A researcher has commented that this past Wednesday his team has discovered that a local freshwater salmon species classified as extinct by the government about seven decades ago, still lives on in Lake Saiko.

Tetsuji Nakabo, Kyoto University professor, commented that he took a look at nine fish from the lake and discovered that they were strikingly similar – in fact the same as – the “kunimasu” or “black kokanee” species of salmon.

If this find is confirmed, it will be the very first time a fish species in Japan which has been classified as extinct has been found living still, the Environment Ministry explained. The ministry has commented it is going to do its best to verify the claims of Nakabo and review its classification of the salmon.

The salmon, a landlocked sockeye, had been seen earlier on only in Lake Tazwa, and was believed to have died off due to an inflow of toxic water sometime in the 1940’s.

However, Nakabo explained there are records which show the salmon’s eggs were taken to other lakes, including Lake Saiko and Lake Biwa, to help improve stocks about half a decade earlier than when they supposedly went extinct.

The species “likely propagated from the eggs from that time,” Nakabo explained.

This discovery came in February, after Nakabo asked fish expert Sakana-kun to show a likeness of the extinct fish.

Sakana-kun requested samples of “himemasu” – a fish similar to that of the “kunimasu” – and discovered they were very similar, and just possibly the same!

Bowhead whales - No connection to the incident.

Foreign Minister McCully has raised the alarm to anti-whaling protesters that ships of Japanese origin will be armed to the teeth, and cautions activists to keep an eye out.

The Cove promo poster

Japanese fishermen led a swarm of dolphins into “the Cove”, a cove which made quite a stir when released in an Oscar-winning documentary, however these Japanese fishermen did not finish the job, and no dolphins were slaughtered.

An inside source in the seaside village of Taiji, which was shown in “The Cove”, has commented that a select few of the dolphins herded were kept to be sold to aquariums, however the majority were set free Friday in the morning. No further details were volunteered.

The decision to let the majority of the dolphin go free is a far cry from the past practice of killing them all.

Sea Shepherd, the conservationist group, has been keeping close tabs on Taiji, with a tiny crew of activists this past week, and has been urging people to aid in the cause of saving the dolphins.

Dolphins swim in large groups, known as pods, in the ocean. The fishermen of Taiji round them up, by making noises which scare them, and lead them to the cove. They then go about selecting the best for sale, and promptly dispense with the rest, stabbing them repeatedly, until the waters run red with blood.

Hopefully this new practice of letting the rest go will catch on, and mother earth will no longer need to shed tears for her lost dolphin children. If the slaughters continue, who knows what will become of the poor dolphins, and the innocents of Taiji.

The area of the census ranges from Japanese to Australian waters.

Japan along with Australia have some of the world’s most diverse oceans, however thousands of the marvelous creatures in their deeps, remain unknown to man, and global warming is a major concern, suggests a newly performed census.

Both Japan and Australia are the proud owners of 33,000 some odd known species, according to a decade long scientific survey of the life in the sea, aptly dubbed “What lives in the Sea”.

However, there could be more than 200,000 species in the vast waters of Australia, which are surrounded by three oceans and four seas, which extend from the icy southern pole, to the coral-rich tropics.

“This constitutes a vast array of highly diverse habitats and ocean features, but many have received limited if any exploration,” wrote Alan Butler, from Australia’s Commonwealth Scientific and Industrial Research Organization, who is the lead author of the work.

The majority of the 33,000 species which were noted for Australia were animals, including fish, seabirds and of course marine mammals, with an astonishing rate of new fish and shark species being found on a continuing basis. Butler has guessed that only about 20 percent of Australia’s total marine species have been discovered to date.

Life was most densely populated in the northeast, which is where the World Heritage-listed Great Barrier Reef makes its home, and is cock full of turtles, colorful corals, dolphins and dugongs.

“Australia is of tremendous ecological interest,” explained Jessie Ausubel, a representative for the marine census. “It is advanced in creating protected marine areas, around coral reefs but also around its deep-sea areas.”

A representative of Japan’s Agency for Marine-Earth Science and Technology, Katsunori Fujikura, has commented that somewhere in the vicinity of 155,000 species have been spotted in the waters surrounding Japan, which only accounts for a mere 30 percent of all estimated life, and only 33,000 have been officially recorded on the books.

“The reason why such high diversity occurs is undoubtedly the varied environments existing in Japanese waters,” explained Fujikura.

Japan’s waters are just about 11 times larger than the land area, and they feature coral reefs, ince bound seas and trenches (which can be up to 10 kilometers deep). The strong ocean currents in the area, mean that roughly 5 percent of the species found there are actually unique to Japanese waters.

By contrast, 19 percent of New Zealand’s 17,000 marine species are found only around the isolated island state, and Antarctica’s Southern Ocean also hosts many species not found anywhere else.

“Most species in the Southern Ocean are rare, with over half of the known benthic (sea-bed) species having only been found once or twice,” explainedHuw Griffiths, a report author, from the British Antarctic Survey.

The extremely remote, and even hostile, Antarctic region is the home to 8,000 some odd recorded species, with sponges, small crustaceans, and moss animals richly represented.

However, over 90 percent of the marine environment is over one kilometer below the waves, and less thn 10 percent of the total deep-sea area has been explored, “implying there are still a great many species yet to be described” Griffiths explained.

Handcuffs

A Japanese company was caught with their hands in the cookie jar. They were caught in one of the biggest fisheries bust in New Zealand, illegally reeling in 600 tonnes of fish.

The Fisheries ministry has said that Kanai Fisheries Company, Aurora Fisheries, a New Zealand fishing company, and four Japanese Citizens have pleaded guilt to a combine 54 charges in the Wellington district court.

Each charge means a hefty fine of up to $250,000, bringing the possible total to a staggering $1,350,000 in damages, not including other penalties.

Andrew Coleman, the Fisheries Ministry’s field operations deputy chief executive, has commented that the operation lasted almost two years, involved 25 staff, and was the biggest operation in the history of the organization.

He went on to comment that the Japanese company bought out part of Aurora Fisheries quota which in turned allowed them to fish in New Zealand waters.

Tomi Maru 87, the company’s fishing boat, then proceeded to catch 112 tonnes of silver warehou and 481 tonnes of ling in a short two year period. The problem is that the area where the fish were reeled in was off the southern coast of the South Island, and outside of Aurora’s quota area.

However the company reported that the fish were caught well inside these boundaries. The export value of the ill gotten fish was estimated to be in the vicinity of $2.4 Million.

It should be noted that even though a guilty plea has been entered, does not mean any convictions will be made… Only time will tell.

Greenpeace Japan has just recently released its “red list” this past 21st of July. This comprehensive little guide outlines the different endangered species which are currently being sold in supermarkets or served up in restaurants.

Greenpeace Japan has launched this “red list”, which is a ranking guide for seafood, in the hopes that it will force supermarkets in Japan to remove the endangered fish from their shelves, and stop selling them.

The Japanese version of this list contains around 15 different kinds of fish, including 5 different kinds of tuna which are very popular locally, which Greenpeace thinks shouldn’t be put on the shelves or in anyone’s frying pan. Research has shown that roughly 25 percent of the world’s tuna and 45 percent of the soon to be extinct Blue Fin Tuna is eaten by the Japanese. Greenpeace is hoping that by releasing this list will help to discourage consumers and retailers from eating the fish.

It should be noted that the fish on this list are those that Greenpeace thinks are susceptible to overfishing, are fished from rapidly depleting stocks, or are reeled in by using methods deemed to be damaging to ambient environments in the ocean and other fish species. The list for Japan includes Atlantic salmon, Bluefin Tuna, Greenland halibut, monkfish, red snapper and sharks. Greenpeace also has country specific lists and can be found on the corresponding Greenpeace website.

One has to ask… If it’s not OK for the Japanese to fish these “endangered fish” why is that same fish not on all the lists for the rest of the world???

bluefin tuna

A whale of a tuna was reeled in off Japan, and turned quite a few heads at a fish market in Tokyo on Friday. This was the largest recorded tuna reeled in since 1986, weighing in at 445 kilograms (981 pounds), and sold for 3.2 million yen ($36,700).

“Many of the people who work at the market have never seen a tuna that big,” said a government official from the Tokyo Metropolitan Government, who regulate the Tsukiji fish market. It is interesting to note that the Tsukiji fish market is one of the largest fish markets in the world.

The monstrous tuna, which was auctioned off at 7,200 yen per kilogram, had already had its guts removed and gills cleaned off, which means this whopper of a fish must have weighed more when it was first reeled in off Nagasaki prefecture this week, the official continued.

“It is extremely rare to see a tuna heavier than 400 kilograms,” he said. Yes it is very rare indeed. Tuna generally only reach the 200 kilogram mark, and it is rare to find one of this size.

The largest Japanese caught tuna ever sold at the Tsukiji fish market was a 496 kilogram specimen reeled in in the spring of 1986. However, the largest tuna recorded in the world came from Canada, caught in 1995 weighing in at an astounding 497 kilograms.

There has been a steep decline in global tuna stocks due to overfishing over the past decades. This has caused Western nations to put in a motion for a trade ban on the endangered Atlantic bluefin Tuna.

Bottlenose dolphin

Tokyo (AP) – “The Cove”, an award winning documentary which exposes a Japanese village engaging in the acts of hunting down and killing dolphins, has finally made its debut on Saturday after being delayed by angry nationalist protests.

Of the six cinemas which started showing the film, a small number completely sold out, and the others were just plain empty. Another 18 cinemas are scheduled to show the film at a later time.

At a popular art theater in Tokyo, Image Forum, somewhere in the neighborhood of 30 protesters were seen brandishing Japanese flags, and were shouting out slogans against the film. The police were seen trying to stop shoving matches between the protesters and the small group of supporters for the film.

The film goers didn’t seem to take notice, and weren’t the least bit reluctant to go and see the film, as the first two showings at the theater were completely sold out.

One movie goer, Tomokazu Toshinai, had this to say about the film, “I didn’t know about dolphin hunting. Whether it’s TV or movies, Japanese have a right to know these things.”

In the last month, three other theaters which were scheduled to show the film canceled the showings, after some rather intense protests and telephone campaign against the documentary. The Nationalist groups are saying that the United States produced film is Anti-Japanese, has no bearing on reality, and is in cahoots with a militant anti-whaling organization.

Sounds weird? If so you haven´t heard about the ”fish mail box” in Inada Park, Kawasaki, Tama River in Japan near Tokyo. The ”fish mail box” is a 7 meter by 4 meter large concrete water tank that have been placed along the river to give people a place to drop unwanted fish. The goal of the fish box is to prevent people from releasing fish into the river, since foreign species can wreck havoc with local ecosystems.

People are encourage to call before they drop off their pets as fish can die from the shock if not acclimatized correctly, but it is is permitted to just drop off fish as well. People are also encouraged to drop off tropical invasive species they catch in the river in the fish box.

The fish left in these fish boxes are cared for by Mitsuaki Yamasaki, 51, the head of a local river fish association, before they are placed in new homes. The box is receiving about 10,000 fish a year ranging from small fish to large gars.

The Tama River has seen a lot of new species released in it in recent years during which the aquarium hobby has become even more popular in Japan than before. This has in no small part to do with the movie “Finding Nemo”, even if the increase in popularity started before the movie was released. More than 200 species of foreign tropical fish have been found in the Tama River ranging from typical aquarium fish such as guppies and angelfish to less frequently kept creatures like piranhas and arowanas, earning it the nick name the Tamazon River. Some of the tropical species have established breeding populations while others haven´t, but most species can survive the winters by staying near water treatment areas along the river.

Mitsuaki Yamasaki and other members of the local river fish association are afraid that breeding populations of gars will establish themselves in the river since more and more gars are sold and they have been found in the river. Gar species are predatory fish that could have a severe negative impact on native fish such as sweetfish . Gars are likely able to establish breeding populations in a river with the conditions of the Tama River.

It can not be denied that with over 10,000 fish received by one of these fish boxes since it opened the initiative could aid the struggle to prevent invasive species from getting a foothold in local waters, and it might be an idea that deserves being tried in other problems areas around the world, such as Florida. The only question is if projects like this could work with out the devotion and support from people like Mitsuaki Yamasaki, people who are really passionate about what they do.

A transparent goldfish that reveals its inner organs has been developed by a joint research team of Mie University and Nagoya University in Japan.

The aim of the project was to create a transparent fish that makes it possible for researchers to study blood constituents and organ behaviour without having to dissect the animal. Unlike ordinary goldfish variants, this type has therefore been made really big and can weigh up to 1 kg. Up until now, the transparent fish of choice for researchers have been the see-through zebrafish, but this tiny fish only weigh abut 3 grams and is therefore much more difficult to study than the 1 kg goldfish.

The translucent goldfish was developed in just three years by repeatedly letting selected pale goldfish specimens mate with each other.

“Pale-colored goldfish have little commercial value, but their negative value has turned into a positive,” said Mie University Associate Professor Yutaka Tamaru.

The creation of a transparent goldfish was announced Wednesday last week at the annual meeting of the Molecular Biology Society of Japan.
