FISH studies are continuing to throw up more mysteries with the latest research showing that fish in the Antarctic region  can  to produce a type of antifreeze  which helps them survive very low sub zero temperatures. However, they also  suffer an unusual side effect in the process as scientists have found that the protein-bound ice crystals that accumulate inside the bodies of the fish resist melting even when temperatures rise. University of Oregon doctoral student Paul Cziko, who led the study said: “We discovered what appears to be an undesirable consequence of the evolution of antifreeze proteins in Antarctic notothenioid fish. What we found is that the antifreeze proteins also stop internal ice crystals from melting. That is, they are anti-melt proteins as well,” he told the  Tech Times. His research has been published in the Proceedings of the National Academy of Sciences.

THE Iceland Atlanto-Scandian herring has almost come to a close with some good catches reported at the finale. The trawler company HB Grandi said one of its vessels, the Faxi RE was then steaming home, having finished its last trip of the season and  another of its pelagic vessels, the Ingunn AK,  had already finished its season, docking at Vopnafjördur processing plant with 900 tonnes on board that has now been pumped ashore. According to Róbert Axelsson, who was skipper on board Ingunn during its last herring trip, there was good fishing deep east of Iceland last weekend. The herring caught in the last few days is large, good quality fish and samples on board Ingunn indicate an average weight of 400 grammes. There was minimal by-catch this trip, apart from some blue whiting and a small amount of mackerel with the herring in the first two hauls.  The company’s mackerel quota has also been caught. Next is fishing for Icelandic summer-spawning herring that is expected to start in early October.

Novartis Animal Health Aqua says it has launched its aquacare, an innovative fish health management software to assist fish farmers continuously improve health management practices for the optimum balance of quality and profitability. Aquacare represents a next generation service platform that will enable higher productivity in collection and management of health-related data, and improved decision-making. The software will begin rolling out to customers in a phased approach starting in August. It has been developed in collaboration with Ocea Mercatus, the aquacare tool that combines the fish health expertise of NAH Aqua with the state-of-the-art farm software capability of Ocea. Combined, the two companies invested a total of $1.2 million to develop this pioneering tool which provides real time information and is a step forward towards improving healthcare best practices and the way technical services are delivered by NAH. NAH is a pioneer in fish healthcare systems with more than 10,000 farm visits logged
by the technical services teams globally since 2002.

ONE in six portions of cod sold in UK fish and chip shops is actually a cheaper species, the consumer watchdog organisation Which? says The revelation comes at a time when the government announced the creation of a new food crime unit which has been set up in the wake of the horsemeat scandal. But it will also look at fish. the  consumer watchdog too DNA samples from 45 portions of cod and haddock bought in Birmingham, Manchester and Glasgow and found that seven of them were whiting. The Which? study is not the first time that fraud has been exposed in the seafood industry. Last year, marine protection group, Oceana, published research showing that a third of fish in supermarkets, shops and restaurants in the U.S. was wrongly labelled.
