Steve Wozniak

Well it certainly seems to be a time for breaking records. An angler has just become the first person in the world to break the ultimate fishing record, by reeling in an astounding 1,000 different species of fish.

Steve Wozniak, a native Californian 47 years of age, has spent a decade on his quest for mastering the creatures of the sea, and he has made his rounds in over 63 different countries to accomplish his goal. He has spent an astonishing 20,000 hours fishing on piers, beaches, riverbanks and boats just waiting for a fish to take the line. He has caught everything from a small minnow to a giant 900 pound beast of a shark.

Steve has shelled out an amazing amount of money, more than 50,000 Great Brish Pounds and has stored up somewhere in the neighborhood of one million air miles by traipsing around the world, his rod and his tackle box his only companion for 10 years.

Steve has made his rounds on every continent minus Antarctica, including such places as the exotic Isle of Wight and the far reaches of Cambodia.

He has managed to capture just about every freshwater fish which calls Britain home and has spent 2 years and 4,000 Great British Pounds trying to land himself an Atlantic salmon from Scotland.

What can we say? The man loves his fishing. In a week full of broken records, we’d like to welcome Steve to the ranks of the Big Fish.

Namibia

Researchers have found a “super fish” which is actually able to not only survive, but thrive in a previously thought uninhabitable region off of Africa’s south-west coast, which also happens to be infested by jellyfish.

This “super fish” is actually helping to keep the local ecosystem going, and is single handedly helping to preserve an important fishery as well.

One of the ecosystems off the coast of Namibia, the Beguela ecosystem, was at one point is history chock full of sardines. However, overfishing of the area, and various other environmental factors have caused the population of sardines to take a nose dive, and the ecosystem became overrun with algal blooms and jellyfish swarms.

The algae has almost consumed the entire oxygen supply of the water, and the waters closer to the surface are full of jellyfish and algae.

It has been discovered that bearded gobies are making their home at the very bottom, and they are the only vertebrate to do so. The stomach contents were examined, and revealed that these bearded fish eat the dead algae which falls from the surface, and they also eat the jellyfish! This astounding discovery was made by Anne Utne-Palm, of the University of Bergen, Norway and several of her collegues.

The team of researchers also discovered that the gobies are able to survive for hours in water with extremely low oxygen levels by lowering their metabolic rate, and when they run low they pop back to the surface for more oxygen!

What a Fish!

The world record for a shark being landed by a fishing rod, has just been broken by two Danish fisherman. Per Jensen and Henrik Hansen successfully landed themselves an 880 kilo, 4 meter and 10 cm Eqalussuaq (also known as a Greenland Shark, or Somniosus microcephalus) in Norway’s Bokna Fjord. The Bokna Ford is in Rogaland County, between Stavanger and Haugesund.

The previous record for such a rod caught shark was said to be in the neighborhood of 775 kilos.

When asked about the adventure, and overall catch, Henrik Jensen responded, “It all went very well”.

The two Danish fisherman had made their way to the Bokna Ford, as they had recently heard that rather big Greenland sharks were prowling the waters. As to the bait? They simply used an empty potato sack full of plaice.

The Greenland shark is not generally considered edible as its flesh is toxic and contains timethylene oxide, which when ingested causes the same symptoms as being drunk as a skunk.

It is interesting to note that if the Greenland shark is prepared in a rather difficult process, it can be eaten, and is even considered a delicacy in Iceland (even more so in Greenland) where the fish, which is not normally a danger to humans in general, is closely tied into the Inuit folklore.

Norwegian fisheries regulators have banned all fishing of the critically endangered European eel starting in 2010 and cut 2009 catch quotas by 80 percent. The Norwegian Ministry of Fisheries also has announced that all recreational fishing of European eels shall stop on July 1st.

The European eel (Anguilla anguilla) is listed as critically endangered in Norway and on the IUCN Red List of Threatened Species. As early as 1999, the International Council for the Exploration of the Seas (ICES) warned fishery authorities about how the European eel stock was outside safe biological limits and that the fishery was unsustainable.

”The Minister of Fisheries is making an important, and the only right choice, and is showing international leadership in fisheries management,” said WWF-Norway CEO Rasmus Hansson in a response to the new regulation. “Norway’s Fisheries Minister, Helga Pedersen, has used every occasion to point out that Norway is the best in the world on fisheries management, and by making bold moves like this they have probably earned the title.”

WWF now hopes that the Norwegian decision will influence the European Union and its member states to do their part in protecting the European eel. As of today, eel fishing is allowed within the EU despite the grave condition of the European stock.

Norway, one of the two countries that openly defy the IWC ban on commercial whaling, has suspended this year’s whale hunt mid-season after catching less than half the quota of 885 whales. The suspension coincides with this week’s annual IWC meeting in Portugal, but is not linked to the meeting or any adjacent negotiations. Instead, a lack of demand in the Norwegian distribution chain is cited as the reason behind the surprising deferment.

“The number of whales killed so far is enough to meet the known demand,” said Willy Godtliebsen, head of sales at the Norwegian Fishermen’s Sales Organisation (NFSO). “They may resume the hunt later if new buyers turn up.”

According to NFSO marketing director Lise Mangseth, the suspension is an effect of the current financial crisis. The financial situation has dissuaded processing plants from freezing and stocking the meat the way they normally do, in order to save money.

“More generally, [the suspension is due to] organisational problems rather than a problem of demand,” Mangseth said. “The whalers are such small actors and the volumes from the hunt are so limited that the distribution chains don’t really want to invest in their product and there are no marketing campaigns as there are for other food products“.

She also claimed that it isn’t unusual for whalers to take a break during the season.

Greenpeace are interpreting the suspension as a sign of waning consumer demands for whale meat.

“If they don’t start the hunt again later this season, 2009 will be the ‘worst’ year for whaling since Norway resumed commercial whaling”, Greenpeace spokesman Jo Kuper said.

Norway resumed whaling in 1993, despite international protests. When Norwegian whalers were asked to suspend their hunt on Tuesday this week, 350 Minke whales had been harpooned since the start of the whaling season in April. Normally, the hunt would continue until October.

Scientists tagging sharks off the Irish coast have tagged a surprisingly high number of Basking sharks this year: 50 specimens in just three days.

“I would normally expect to be lucky if we tagged 50 in a whole year,” said Dr Simon Berrow of the Irish Whale and Dolphin Group.

Basking SharkA record

Together with National Parks and Wildlife Service conservation ranger Emmett Johnston, Dr Berrow set out earlier this week to tag sharks off Donegal, as part of a project funded by the Heritage Council.

“In two hours last Monday we tagged 23 sharks, and we found 19 the following day – four of which had been tagged the day before,” Dr Berrow said. By the third day, they had tagged their 50^th basking shark.

Basking sharks were once a significant source of income for Irish whalers and the coastal towns of Galway and Waterford did for instance have street lights lit with basking shark oil as early as the 18^th century.

The importance of Basking sharks in Irish culture is evident in the number of names and monikers give to these peculiar creatures. In Irish, this “monster with sails” is known under the names Liabhán chor gréine (Great fish of the sun), Liop an dá (unwieldy beast with two finns) and Liabhán mór (great leviathan) – just to mention a few. The epithets “Fish of the sun” and “Sunfish” both pertains to its fondness of swimming just under the surface.

In the mid-1970s the Irish stopped their whaling, but the problems weren’t over for these sharks since they frequently ended up as by-catch in drift nets; a fishing method now outlawed in Irish waters. In addition to this, Norwegian whalers continued to hunt for shark off the Irish coast until 1986.

The Basking shark (Cetorhinus maximus) is listed as Vulnerable on the IUCN Red List of Threatened Species, and is a protected species in Great Britain but not in Ireland. However, the European Union has just placed a moratorium on fishing for Basking sharks in these waters.

If you spot a Basking shark in Irish waters, the Irish Whale and Dolphin Group would very much like to know any details about the sighting. You can find more information at www.baskingshark.ie.

Japan needed to cede more ground, says outgoing head of the International Whaling Commission (IWC) William Hogarth*, voicing regrets over his failure to design a compromise regarding Japanese “lethal research” on whales.

After a meeting next month in Portugal, Hogarth will step down as both US delegate and head of the world whaling body. While announcing his disappointment in leaving the chairmanship without having resolved the “scientific whaling” issue, Hogarth also said that his efforts brought civility to the IWC, where annual meetings had long been showdowns between pro- and anti-whaling nations.

Norway and Iceland are the only nations that hunt whales in open defiance of the 1986 IWC moratorium; Japan is instead using a loophole in the moratorium that allows for lethal research.

In a series of closed-door negotiations with Japan and other nations lead by Hogarth, Japan allegedly offered to reduce but not end its annual Antarctic whale hunts; an offer which infuriated the neighbouring countries Australia and New Zealand.

Japan accuses Western nations of cultural insensitivity and is currently pushing for the IWC to accept whaling of the coast of Japan, since whaling is a time-honoured Japanese tradition.

One of the highlights of Hogarth’s time as head of the International Whaling Commission was a compromise brokered by him in 2007, in which Japan agreed to suspend plans to expand its hunt to include Humpback whales – a species that haven’t been hunted by Japanese whalers for several decades.

The remains of a 15 meter[1] long sea living predator has been found in Svalbard, an archipelago located about midway between mainland Norway and the North Pole. The animal, a species of pliosaur dubbed Predator X by the group of scientists who discovered it, lived in the ocean 147 million years ago during the Jurassic period.

The skull of Predator X is twice as big as the skull of a Tyrannosaurus Rex and researchers believe the jaws of this hunter could exert a pressure of 15 tonnes[2]. The weight of the live animal is estimated to be around 45 tonnes[3].

“It is the largest sea dwelling animal ever found and as far as we know it is an entirely new species”, says palaeontologist Espen Madsen Knutsen[4] from the Olso University in Norway to Swedish newspaper Dagens Nyheter.

Knutsen is a part of the research team who dug out the skull and backbone of the creature during a two week long research expedition to Svalbard in June 2008. The remains were first discovered by Professor Jörn Hurum[5] from the Natural History Museum at Oslo University in 2007. Hurum noticed a piece of bone sticking up from the permafrost, but since it was the last day of the 2007 expedition the group was forced to leave the bone behind without any further investigation after having jotted down its GPS position.

Parts of the head and backbone was dug out during the abovementioned June 2008 expedition and together with an earlier find of a smaller specimen of the same species located just a few kilometres away, scientists have now managed to map together a good picture of what the live animal once looked like.

“We haven’t unearthed a high number of parts yet, but the parts that we do have are important ones and this has made it possible for us to create an image of what Predator X once looked like”, says Knutsen.

In the excavated area, palaeontologist have found roughly 20,000 bone fragments – the remains of at least 40 different sea dwelling Jurassic animals. Once you’ve started digging in this region, it is fairly easy to spot the bones since their pale colour contrasts sharply against the black earth of the Svalbard tundra. The main difficulty is instead the short dig period and the fact that much time is spent restoring the excavated area after each dig.

“Each time we leave a dig site we have to restore the area. There can be no traces of our activities. This forces us to use half of our time digging up the same spot all over again when we return”, Kutsen explains.

Svalbard lies far north of the Arctic Circle and the average summer temperature is no more than 5°C (41°F), while the average winter temperature is a freezing −12 °C (10 °F). In Longyearbyen, the largest Svalbard settlement, the polar night lasts from October 26 to February 15. From November 12 to the end of January there is civil polar night, a continuous period without any twilight bright enough to permit outdoor activities without artificial light.

The team plans to return to Svalbard this summer to carry out more digging. They hope to find another specimen in order to make the skeleton more complete, and they also wish to unearth the remains of other animals that inhabited Svalbard at the same time as Predator X.

If you wish to learn more, you can look forward to the documentary shot by Atlantic Productions during the Svalbard excavations. The name of the documentary will be Predator X and the animal is actually named after the film, not the other way around. The film will be screened on History in the USA in May, Britain, Norway and across Europe later this year and distributed by BBC Worldwide.

Scientists from three different European countries – Norway, Belgium and the UK – are now launching a new research project where the aim is to find out if cods can feel pain or not.

“Most people agree that mammals and birds can feel pain, but people are less sure about fish,” says project leader Øyvind Aas-Hansen of NOFIMA, an aquaculture research institute whose headquarters are in Tromsø, Norway.

Fish show many signs of being able to experience pain, but we still know very little about how their brains react to stimuli that would cause mammals and birds to feel pain. According to some scientists, the brain of a fish is not equipped with certain structures needed to process pain, but others believe that fish nevertheless do sense some type of pain.

What we do know is that fish show a long row of behavioural responses that could be interpreted as signs of pain, such as avoidance reactions. Fish are also capable of producing pain-relieving opiates and the fish brain is equipped with receptors for both pain and opiates.

The European researchers hope that modern medical technology, especially functional magnetic resonance imaging (fMRI) and electroencephalograms (EEGs) will make it possible for them to learn more about how the cod brain actually works. The aim of the study is to indentify which parts of the cod brain that becomes activated when a cod is exposed to potentially painful stimuli, and the researchers will also study how these signals are processed.

In order to test the brain of a fish, there is no need to expose it to any type of severe or prolonged pain; a mild stimulus that simply provokes an unpleasant sensation is enough to see how the brain reacts. “We will use the same procedures as those used on healthy human volunteers,” Dr Aas-Hansen explains.

If cods are indeed able to feel pain, Dr Aas-Hansen hopes that the results of the study will be used as yet another argument in favour of keeping aquarium fish in benevolent conditions. The study is however unlikely to affect European legislation since most regulations already assume that fish can feel pain.

Dr Aas-Hansen also points out how comparative research on how the brain works in different animals can give an insight into our own human brain. “This is ground-breaking work,” he says. “No other scientists have previously studied the cod’aquarius brain this way.”

The project will run for three years and is funded by the Norwegian Research Council.
