Etrumeus teres: ウルメイワシ

By Y. Iwata

Introduction

image00A round herring is a fish often eaten in Japan. However, few people know very much about a round herring. Therefore, I think that I would like to introduce a round herring.

Description&Taxonomy

The round herring belongs to order herring clupeidae herring, and if it grows, it will be set to about 30 cm.Since eyes seem to be greatly wet, it is called the round herring。The back side of the color of the body is indigo, and the belly side is silver.Moreover, the lower jaw has projected before for a while rather than the upper jaw.

Range & Ecology

The round herring inhabits the warm and shallow sea in the world, and, of course, also inhabits the Tosa bay. A round herring goes north from spring in summer, and goes south from autumn in winterTherefore, it appears in the Hokkaido coast in summer.Food is plankton.

Use & Conservation

A round herring is used as a dried food, and is also served as sashimi or grilled with salt.

Hammerhead shark

by S.Y.

Introduction

image00A common Hammerhead shark is living the coast of the warm seas of the world. And they are living the sea of Kochi. I touched Hammerhead shark with a neighboring fishmonger for the first time in the days of a high school. I was fascinated what attractive. Hammerhead shark is called “Shumokuzame” from the form of the head such as wooden bell hammer ringing Japanese musical instruments in Japan, and in English, the form of the head is likened with a hammer and it is called “Hammerhead shark”.

Description & Taxonomy

Hammerhead shark is a generic name of a shark belonging to order Carcharhiniformes family Sphyrnidae. Nine kinds are known all over the world. Full length is 5 meters, and the big thing becomes 6 meters. Since the head spread horizontally like a hammer and it is sticking out, Hammerhead shark can be recognized immediately. The body back is gray and brown, yellowish-brown, and the ventral is white, there are not the fleck outstanding in particular.

Range & Ecology

Hammerhead shark lives the sea to 100 meters of depth of the water and sometimes sink to 300 meters of depth of the water. They live the offing mainly, but live the coast, a reef, and the estuary. They chase food and may come near a shore. Since eyes stick the both ends of the head, they have a view larger than other sharks, and food can be looked for easily. Hammerhead shark is a strong predator, and they feed not only fish and a cuttlefish and an octopus and Crustacea but also other sharks and prey on one another. Their favorite food is Dasyatis akajei, and they eat to the sting of a caudal fin. They move to high latitude sea area in summer, and come back to the tropical zone when it is winter. Although the life is unknown, probably about 30 years are presumed. Hammerhead shark forms a group uniquely as a shark, and acts. Occasionally the number may amount to hundreds of them.

Use & Conservation

Hammerhead shark is processed into the dried fish called “Maira” and “Tetsuboshi” in Kochi. It matches rice well. The things which is the most terrible for Hammerhead shark is fishery and indiscriminate hunting. It is said that the shark killed by human being becomes from 50 million to 100 million of them a year. In this situation the sharks become extinct. The important thing is Hammerhead shark is only one animal alike other animals, and everyone understands that they are by no means atrocious killer. Hammerhead shark is kept in many aquariums, and their mysterious shape attracts the eyes of many people. And it’s may appeal for the need of the conservation of the shark.

Viewing

If you want to meet Hammerhead shark in Kochi, let’s go to Niyodogawa after the heavy rain. They come to the mouth of a river of Niyodogawa after the heavy rain. Hammerhead shark is one of a few sharks attacking the human being, but is not ferocious as a rumor because they becomes rarely aggressive. If you come across Hammerhead shark in the sea, please read the action exactly calmly. The probability attacked by a shark is hard to happen than being struck by lightning than being stung by the hornet.

Maaji : Trachurus japonicas

by T. Furukawa

Introduction

The aji is one of the most popular fish. It is the maaji which is often seen especially in Kochi. It is at the fresh fish corner of a supermarket mostly. It is the fish that anyone has eaten at once.

The signal which thought that I would investigate about the maaji is lure fishing of the maaji which went together with my friends. Although I was interested in the fish from before, the fish which can be easily fished using bait called the aji did not have interest in particular. However, when I began fishing using lure, unlike bait, I was not able to fish the aji easily. Therefore, I wanted to understand the aji more and investigated about the ecology, the habit, etc. of the aji this time.

Taxonomy & Description

The scientific name of the maaji is “Trachurus japonicas”. The maaji is lone of the kinds included in “Perciforbes-Carangidae-Trachurus”.

The fish of Carangidae generally have two dorsal fins and they have 1~2 strong thorns before the anal fin. Those forms resemble the flat leaf of the broadleaf tree, and the sections are a long and slender spindle shape. Moreover, there are scales popularly called “zengo” on the lateral line on the body side. They are large and strong compared with the scales of the portion of other body. The back color is dark and the abdominal color is bright. (It changes with kinds.)

Range & Ecology

Many maajis ranging the south Japan except Okinawa and the East China Sea. They crowd together and inhabit the reef region with the depth of 1~150 meter. The maaji ride on a warm current around January, and go north. And they go south around autumn. “Kiaji” and “Kuroaji” of two kinds are mainly in the maaji. The kiaji establish on the coast and live. They establish to the reef the coral reef and the sandy mud bottom which are on the coast. The kuroaji migratory offshore and live.

The feeding habits of the aji are carnivorousness and eat the zooplankton, small fish, the crustacean, shellfish, the cephalopoda and the polychaete etc. Since the inside of the stomach of the aji will be empty in one day, they take food every day. Their natural enemies are birds and large-sized carnivorous fishes beside humans. The body color of maaji can defend themselves from such a natural enemies. Moreover, they have the character to flock to light. And they flock in quest of the strength of the most suitable light. However, the strength of the suitable light changes with environmental conditions at that time.

Use & Conservation

The maaji are mainly used for food. How to eat is various and especially sashimi, the broiled with salt and the dried fish are delicious. DHA which activates the brain and EPA which lowers cholesterol are abundantly contained in the aji. Moreover, they are used as bait when fishing a cuttlefish and a flatfish, or are treated as the object fish of fishing. It is in how to fish the aji variously, and there are mainly “sabiki fishing” and “lure fishing”.

Viewing

We can be seen the aji mostly in the whole sea in Kochi Prefecture. In the sea near Kochi University, we can be seen they to Urado bay and Usa bay etc. The best season is from August to March.

Dark Chub: Nipponocypris temminckii

by T. Nakayama

I caught this in Yusuhara town during golden week.

Introduction

Do you know kawamutsu? It is seen in narrow waterways , a lot of rivers. In early summer, we watch the fish change color.

Taxonomy

Its scientific name is Nipponcypris temminckil. It is a member ofCypriniformes(called “koi” in japan). It is called Dark chub in English.

Range & Ecology

Kawamutsu is major river fish in Japan. Its size is 10-15cm and is found in many rivers. It lives in West Japan and East Japan. During breeding season, Kawamutsu’s body change breeding color. Male kawamutsu change into red color, in body, shallow water spawn.They eat aquatic insects, crustacean, small fish, and algea. Kawamutsu is omnivorous.

Use & Conservation

Kawamutsu called one of species “Haya” staple Ugui, and Oikawa . “Haya” origin Japanese word “Hayai” In Japan, people eat “Kanroni”,”Karaage” and so on.

Where to see in Kochi

Kawamutsu is seen a lot of river and narrow waterways. So we can watch near Kochi University.During the recent Golden Week holiday, I went to Yusuhara town. Yusuhara town have river source of Shimanto river. It very beautiful. It is important to protect river and preserve the animal ecology.

Pygmy seahorse: Hippocampus bargibanti

by Y. Nagano

Introduction

Have you ever heard of a living creature called pygmy seahorse? It is very tiny seahorse which has only recently been discovered. It was difficult to spot due to its mimicry capability and small size.

Taxonony

The classification of Pygmy seahorse is still being debated, but it is a member of the seahorse family. Any seahorse with a length of about 20mm is called pygmy sea horse. Therefore, there is not a regular classification called pygmy seahorse.

Range & Ecology

It is said that pygmy sea horse has many place witch were just discovered in 1999 years and have not been discovered yet. Therefore, specification of distribution is not yet understood. As a known place,they are temperate areas and tropical areas, such as South America and Africa,globally.

Pygmy sea horse is seen in Japan in Kashiwajima, Hachijozima, Okinawa, Kishuu, Izu, etc.
Since pygmy sea horse seen in Japan differs in appearance, it is called Japanese pygmy seahorse.

Use & Conservation

Pygmy sea horse is new! Therefore, for a diver, it is extremely popular. Of course, a diver trade association will profit, if the diving position which pygmy seahorse inhabits is known. Then, scramble of pygmy sea horse is carried out.

This is actual to an ashamed thing in Japan. Argument does not cease between diver contractors or among communities by that.
In order to prevent these, the statute which does not break the ecology of pygmy sea horse is required. For that purpose, it must be indicated as a new species.

Where to see in Kochi

The place where pygmy sea horse is seen in Kochi is kashiwazima. Kashiwajima is a place where tides, such as the Japan Current, collide, and it is famous for the four seasons in the sea. Much coral which colors the sea is the highlights. The kind of fish gathering in kashiwazima drops to 1/3 of whole Japan. How about searching, when diving by Kashiwajima? You can see pygmy sea horse, if you have diving ability.

Phoxinus

by K. Gempei

Haya is a generic name for Phoxinus, a fish with elongated medium-sized body among cyprinid freshwater fish from Japan. Main fish are Aburahaya (Amur Minnow) , Ugui (Japanese dace), Oikawa (Pale chub), Kawamutu (Dark chub),  takahaya( Upstream fat minnow), and numamutu (a subspecies of Kawamutu).

Description & Taxonomy

Takahaya grow to a length of about 10 cm and have elongated spindle-shaped form. Their body color is dark brown and dim gold small dots are scattered on their side of the body. Scales are small and their skin has strong slime.

Takahaya belong to a subspecies of Chinese minnow indigenous to Japan. There is a fish very similar to Takahaya. It’s an Aburahaya. The point of distinction with Takahaya and Aburahaya are that takahaya’s tail height is higher and form is stockier than Aburahaya. In addition, Takahaya’s body color is more yellowish than Aburahaya. Furthermore, Takahaya’s scale is bigger and width of head is wider than Aburahaya. However, having large individual and locality differences, these features are not perfect in that distinction.

Range & Ecology

Takahaya live in upstream areas of rivers in west Japan. They gather at a deep pools and stagnant pools gentle stream. They tend to prefer cool water. If it is a small river that has a steep slope and there are no other fish, they will be able to live in an estuary. They live in not only a main course of a river but also a pond or an irrigation canal flowing in clear water.

They are omnivorous and eat insects, plants seed and stuck algae. They live in more downstream area than yamame (Seema) and amago(Red spotted masu trout) and upstream area than kawamutu(Dark chub) as segregation of other freshwater fish. In addition, they live in more upstream than Aburahaya in Honshu.

They spawn from spring to early summer and in this term, male snout change like spatula. When they spawn, a number of them gather at muddy sand or gravel bottom in upstream and spawn stirring up bottom sediment. Fish called haya is eaten by carnivorous fish like catfish or black bass.

Use & Conservation

They don’t sell as an edible fish. Their taste is so-so.

Takahaya have been designated an endangered species by the prefecture. In Tokyo takahaya has been designated the most dangerous state (※vary by region and season). But this is not enough to worry about extinction.

They are famous as Gedo in mountain stream fishing. (Gedo is a fishing term. Gedo is a fish other than the favorite targeted fish. Often used when someone had a fish take the bait. ) So even beginner can catch easily, they are good fish to enjoy fishing.

Viewing

They living in throughout west Japan, we can see anywhere. If you go to Gifu Freshwater Aquarium World・Aqua Toto Gifu, you can see not only haya but also relation with other fish. Aqua Toto is one of the largest freshwater aquariums in the world. There are also amphibians and reptiles live in near water, so even someone who be not interested in fish enjoy there. In kochi you can see haya at Shimantogawa gakuyuukann.

Fresh water fish in Kochi : Donko

by M. Takano

Odontobutis obscura is called “donko” in Japan. But it is also known as cozikimara (Shiga Prefecture), doroboume and dokan (Kinki district), ushihustu (Wakayama Prefucture), Donpo (Nagasaki Prefucture) and Gomo Anagomo in various places in Japan. The generic family of Donko is gobioidei . Among the  Gobioidei of Japan, donko are rare fresh water fish.

Description & Taxonomy & Range

Donko can be as big as 25 centimeters in diameter. They are larger than other Gobioidei fresh water fish in Japan. The head is bigger other Gobioidei. The mouth is big and the lip is thick. There are fine teeth on an upper and lower jaw. Pectoral fin has evolved. The pelvic fin has divided into two sections and Coloring is Brown. They are classified into the Odonto butidae family Perciformes. This specie is set as type species of the Odontobutis Bleeker ,1876 from East Asia. In old times,the population distributed around Japan to be a kind. But there are five groups in Japan: “Yamakage, Biwa, Ise, Hitomi, Higashisheto , Nishiseto, Nishikyuusyuu, Hitomi group became “Odontobutis”

Ecology

They live in rivers, lakes, ponds, rice paddies and irrigation canals. Donko like places where water flows gently , and spends all its life in a fresh water environment. They live alone and are territorial. They are Nocturnal, and in daytime, Donko live under the rock or water plant. They  are predacious  to small fish, aquatic insects and crustacean, but don’t react to the one that doesn’t move. The breeding time is July flow April. The female lays in the nest, and the male looks after the eggs. There is a brood parasitism situation too. The fly that hatched is already big . Of  the fresh water Gobiodei, there are three varieties in Japanese: “Donko’’ “Ishidonko’’and “Kawayoshinobori.’’

Use & Conservation

Donko are sometimes, though rarely, used for food. The cooking method the fry without coating and the salt scorch. And, meat is white meat and so very delicious. But as a rule, they are not eaten raw. They are likely to be kept as a pet. since they are comparatively easy to care for. The habitat of Donko is decreasing now due to the pollution of water.

Viewing

If you would like to swim in rivers, try the Niyodo or Shimanto rivers in Kochi. The Donko live in the bottom in the river welcome you at that time. And if a Donko fish nibbles your foot, it means good luck!

Japanese lates

by Y. Nishioka

Description

Japanese lates is rare fish. First, they are very few to be fished by fisherman. Next,
they are endemic in Japan and distribution is narrow. They live in Kochi and Miyazaki.
Then, they decrease by public business like reclamation. Finally, they are appointed en-
dangered species.

Ecology

The biology of Japanese lates is interesting. First, they are nocturnal and very alert.
And they are a bottom dweller in shallow water in freshwater, estuaries and the ocean. Next, their fry are known to have been observed in ecology. It seems to mimic in the dead leaves on their head state on eelgrass bed. And, they eat animal like fish, crustacean, and polychaete. Finally, spawing season is speculated June to July.

Taxonomy

Barramundi is similar to Japanese lates, but different species. To begin, both of them
are length of 1 meter, body is metallic gray in overall color, darker upperparts and ligh-
ter underparts. Next, Japanese lates has eyes which gleams red in the darkness, but Barramundi has eyes which gleams gold in the darkness. To finish, their anal fin are
different. Second spines is the longest of three spines of anal fin, is Japanese lates and Third spines is longest of three spines of anal fin, is Barramundi.

Nile perch is similar to Japanese lates too. First, Nile perch is bigger than Japanese late. They reach maximum length of about 2 meters, weight is 200kg. Next, they eat fish, crustacean and insects. their fry eat zooplankton. And, their body is silver, their eye is dark black. Finally, they feed impact at planted lake. In Lake Victoria, endemic species decreased and small groups are extinct by arrival of Nile perch.

Viewing

Finally, Japanese lates lives in Shimanto river and Urado bay. They are appointed endangered species. If you go to Shimanto river or Urado bay, you must not fish them. They are very rare fish.

Chub mackerel

by T. Nishida

Scomber japonicus, or the Chub mackerelhas been eaten long by Japanese. Scomber japonicus is one of Scomber. Japanese eat many S.japonicus every year. S.japonicus in Miyagi is became brand and called “KINKA SABA”. Its name is different from each area. For example it is called Hirasaba in Kochi and Shizuoka, Hirasu in Nagasaki, Takkuri in Kagoshima, Honsaba in some area.

Taxonomy

Family is Scombriae, genus is Scomber and species is S.japonicus. There are is four varieties of the genus Scomber: Scomber colias, Scomber scombrus, Scomber australasicus and Scomber japonicus. S.colias range from western the Atlantic Ocean and resemble S.japonicus in form. S.scombrus ranging from northern the Atlantic Ocean. S.australasicus have many black spots on belly. S.japonicus resemble S.australasicus in form but it don’t have a black spot on belly.

Description

S.japonicus is fifty centimeters long. Their body is slender and ellipse. Their scale is small. Lateral line’s scale is 210 to 220. Back is greenish-blue and black curved lines. Belly is silver and white.

Range

S.japonicus live facing warm current of semitropic and temperate water. They like water temperature of 14 to 17 degrees.

Ecology

S.japonicus make cloud and swim surface coast. It travel to north on spring and south on fall. It travel 10km per a day. There are shoal which stay around area of rock too. It eats small fish, zooplankton and cephalopod. The laying eggs season is February to August. They lay eggs which is 1mm across and a number of eggs are from 100000 to 1400000. Many fry are eaten by other fishes because they are not protected by parents. Its life span is 6 to 7 years.

Use

S.japonicus is eaten by human all over the world and it become supplement because they contain a lot of DHA and EPA. Its season is fall and winter, but it is bad on summer. When we eat it, we mind Anisakis. Anisakis is worm and finally parasite on mammals. We especially mustn’t eat raw fish.

S.japonicus is eaten by people of Kochi, but S.australasicus is more famous than S.japonicus in Koch. It is because in southwest Kochi catch S. australasicus which is called “Shimizusaba” by Tosa. Its season is fall to winter but we can eat all the them year around. It is delicious so it is famous in Japan.

Conservation

S.japonicus are not protected because they are plentiful.

Marbled Rock Fish

by N. Takimiya

Do you know the fish that we can fish easily and is delicious to eat ? Its scientific name is Sebastiscus marmoratus better known the Marbled rock fish. This fish is loved by many people the old days in Japan and has eaten many people. So this fish has as many as 13 dialect names, gashira,  or gare in the Kansai area; bokka in the San’in region, bokkou in Shimane, akamebaru, akatinn in Okayama, gakane in Tokushima, hogo in Hirosima and Ehime, gagara, hogo in Miyazaki , arakabu , garakabu, gabu in Kumamoto and Kagoshima.

Description & Taxonomy

The fish grows to a maximum total length 30cm and weights of 2.8kg. It’s body color is usually seen in the light-colored irregularly shaped spots on the brown-red back, the body colors and patterns are due to mutations in habitat and populations. This body coloration is a kind of the adjustment that comes not to be found easily from the enemy and the catch by the color matched to the rock and the seaweed. The body coloration is different according to the place where it lives. For instance, the fish that lives in a shallow place has the color of the rock and the seaweed.

This is on the other hand because of a body red color’s being counterbalanced to blue light of the environment and seeing a sober gray, and becoming a protective coloration the fish that lives in the depth is vivid red in a blue sea.

The section of the body is round, eyes are small, and the fish’s mouth is also bigger than the rockfish. To fish, it is necessary to take care because there are sharp barbs on the fins.

This fish belong to Scoroaeniformes, suborder Scorpaeniformes, family Scorpaenidae, subfamily Sebastinae, genus Sebastiscus, species S.marmoratus. The origin of the generic name comes from Sebastos of Greek, and the trivial name comes from Latin that means the marbling.

Range & Ecology

It is found from Hokkaido to the southern Penninsula, China, Taiwan, and Philippine waters until distributed. In Kochi, S.marmoratus lives off of the Katsurahama beach, and in Urado Bay.

It lives in the area of reef near the coast, hollows of rock and tetra jar and port surroundings to about 200 m depth and lurks in the shadows during the day, strike out looking for food at night.

Also it is an ovoviviparous animal and mates in autumn and produce tens of thousands of small fish in 1~3 months later. The fingerling in the mother’s grows up in the nutrient of the yolk. It lives in outside body in April ~Novemver.

S.marmoratus eats the mussel worm, the crustacean, and the fingerling.

Use & Conservation

S.marmoratus is very delicious because this fish puts on much fat. So this fishes are used cooking, slowly in a soy broth, deep-flying, broil that has been srinkled with salt. Actually, I have eaten my father caught by deep-flying and it was very delicious. But the supermarket and fish shop cannot see so much because the price might be high.
Many S.marmoratus exists sea of Japan. But the protection activity is actively done.

Let’s introduce you two activities. One is in Nagasaki, in the southern part of Ariake Sea, the resource management activity of  S.marmoratus that the haul is in the decreasing tendency every year is done. The other is being done by TOYO SUISAN. Those activities are in both regions and the fry discharge activities and come from a idea to achieve a rich sea-making for the future.

Viewing

If you would like to see S.marmoratus, you can see to go fishing in shallows. This fish can be caught even by the beginner. In Kochi, you can see it in The Takaoka fishing port, The Yoshikawa port, Katsurahama, Muroto, Urado. Let’s fish also by you holding out.

Fish in Kochi of fresh water:Ayu

by N. Kishita

Many species live in Kochi. In the species, famous creatures living a clear river in Kochi are exist. One of them is ayu.

Description

Ayu is about 25 cm long and are a fresh water fish living a clear stream in Japan. They live in Shimanto River, Niyodo River, Yasuda River, Monobe River, Shinzyou River, and so on. Ayu comes down the river immediately after they hatch from the spawns, it enters the sea, spends winter, goes back the river again next spring, it parents, and spawn is laid in autumn. The one to go up from spring to summer is called “Noboriayu” and the one that descends the river to lay spawns in autumn is “Otiayu”.

Use & Conservation

The ayu in Kochi is known as a special product of Kochi, and to fish, is visited from summer to autumn by many clients. When making in edible ayu, the ayu might be called “Sweet fish” to have a peculiar smell. Adult fish’s ayu comes to eat the moss that is attached to the stone in the riverbed. So, the ayu that grow up eating the pure moss in a clean river isn’t a bad taste, and we can enjoy a smell the ayu original. Ayu’s cooking method is ayu grilled with salt, candied ayu, ayu sushi, and so on.

“Hifuriryou” done in summer is a traditional fishing method that has been taken over the Niyodo River and Shimanto River now. Hifuriryou can catch ayu by driving in them by the flame of the flambeau that shakes to a dark surface of a river. A fantastic flame that floats on the night of summer is Shimanto River’s poetic events of summer.

However, ayu’s poor catch becomes a serious problem in Shimanto River and Niyodo River, and so on in recent years. The decrease of haul is caused by a decrease of stream flow, the deterioration of the water quality, the change in the river, a decrease in the nursery area place, and the factor such as decreases in fry’s run-up in either river. In an effort to increase their number various activities are done, such as releasing ayu, independent changes of the fishing season of each fishery cooperative, and holding the symposium is done.

Viewing

Kochi’s ayu is one kind of typical fishes in Kochi, other prefectures’ people also love. It is necessary to do inhabitants of the prefectures best to protect the ayu now since the number of ayu decreases.

Akame

by R Yamamoto

Introduction

The “Master of Shimanto river” is an another name of “Akame”. Its scientific name is Lates japonicas.

Description & Taxonomy

First,“Akame” is 1m long. Secondly, they are named “akame” in Japanese which means “red eye.” This comes from their eyes shining red in the dark when light is reflected. Their face is similar to perch. We can fish for it in Cape Asizuri in Kochi. Finally,they are kind of perch. There are some kind of them. For example “Baramandy”which lives in southeast Asia. Taiwan and Australia “Nile pearch”and “Pseud Akame”

.

Range & Ecology

 “Akame” live in Japan only.In especially,West Japan. Their fry live in water-weed and eating water-insect. And when they grew up,they can lap ocean and river some level, starting eat fish.

Use & Conservation

“Akame” is usually cooked into sashimi and salty baked fish. And they are popular for target of fishing. However their unusual size has led to over fishing. As a result, their number are decreasing.

Viewing

If we continue over hunting to them,”Master” may disappear. It is duty for us to protect unusual creature. And I like fishing very much. So I want to fishing Akame. I heard we can fish Akame in Cape Asizuri from person of Kochi. Two weeks after, we will have a summer vacation. So,I think I will go Cape Asizuri for fishing Akame.
