IN BRIEF - Devon scientist discovers 20% of male fish now 'trans-gender or intersex'
Tuesday, July 18, 2017
Household chemicals flushed down the drain are making fish confused about their gender, an Exeter scientist says.
Twenty per cent of male fish tested in English rivers are now “trans-gender” or “intersex”, with both female and male characteristics, research by Professor Charles Tyler, a leading fish physiologist and eco-toxicologist from the University of Exeter, has shown.
Male freshwater fish are displaying “feminised” traits, demonstrating “female” behaviour and even producing eggs. And anti-depressants are reducing the natural shyness of some fish.
Exports to China obtained an impressive growth of 60.5% with an estimated value of USD 629.26 million, accounting for 18.1% of Vietnam’s total shrimp export value. Meanwhile China’s shrimp imports are on a strong upward trend to meet rising consumer demands for year-end festivals, especially the Lunar New Year.
The trend also pushes shrimp raw material prices up in some neighbouring countries, including Vietnam. With the move, China is likely to surpass Japan to become the second largest consumer of Vietnamese shrimp in the first quarter of next year.
However, Vietnam just ranks eighth among biggest suppliers of shrimp products to China, trailed by Ecuador, Canada, India, Greenland, Thailand, Argentina and Indonesia.
Wild salmon exposed to open-net fish farms are much more likely to be infected with piscine reovirus (PRV) than those that don't have that contact, a new study has concluded.
The data also show that the virus makes it more difficult for wild salmon to swim upstream to their spawning grounds, which has major implications for the sustainability of the populations.
"The government has to remove this industry from the key salmon migration routes or we risk the complete loss of wild salmon in this province," said Alexandra Morton, lead author on the report and an outspoken advocate for wild salmon.
Bangladesh lags behind most other countries in adoption of modern technologies for shrimp farming and utilisation of economic potential, experts said.
The coastal districts of Bagerhat, Cox's Bazar, Khulna and Satkhira have the potential to become the wealthiest areas of Bangladesh if the opportunities in shrimp and prawn aquaculture are properly explored, they said.
A collaboration of the government, investors, financial institutions and technical specialists is needed to make this happen, they said in a three-day seminar in Cox's Bazar that ended on Sunday 11th of Decemeber 2017.
The United States Department of Agriculture -Safe Aqua Farming for Economic and Trade Improvement project of the Winrock International with the assistance of the WorldFish and the Bangladesh Shrimp and Fish Foundation organised the event.
The programme was organised for bagda hatchery owners and technicians to inform them of the recent international developments in shrimp hatchery technologies.
New Zealand’s efforts to ban harmful fishing subsidies are to be praised, writes Mark Peart.
The public and political furore over the now discarded Trans Pacific Partnership (of which New Zealand was a founding proponent) masked the true extent to which regional and multilateral trade liberalisation can be a force for good.
The revised TPP now goes by the much clunkier moniker of Comprehensive and Progressive Agreement for Trans Pacific Partnership (CPTPP). The revised deal has been lauded by Trade and Export Growth Minister David Parker as an improvement on the old TPP, because it contains much greater benefits for New Zealand, particularly improved agricultural market access.
The intent of this piece, however, is not to try to analyse the new agreement in its entirety, but instead focus on one unheralded, yet important element on which government trade negotiators have spent the past 20 years trying to achieve regional and multilateral agreement.
A three-year project geared at developing sustainable solutions to improve seafood safety and dietary properties has been launched.
SEAFOODTOMORROW, a EUR 7m European Union Horizon 2020-funded project, brings together 35 partners from across Europe. It aims to connect them with up-to-date technology and market-orientated expertise to meet challenges likely to develop over the next 30 years.
It was launched at the Instituto Portugues do Mar e da Atmosfera (IPMA) in Lisbon at the end of November, with all partners meeting for the kick-off event.
Springfield Smoked Fish of Springfield, Mass.is recalling its 1lb. packages of Prescliced Nova Salmon because they have the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious infections in young children, frail or elderly people, and others with weakened immune systems.
The recalled packages were distributed to customers in Rhode Island and Connecticut through retail stores.
The product comes in a 1lb, clear plastic package marked with lot # 42173 on the back of the package and with an expiration date of 12/22/17. UPC 811907018018.

Fishermen across the country are set for a boost as the UK government’s commitment to sustainable fishing secured significant quota increases for key stocks at this year’s annual negotiations. This included an increase in quotas of North Sea Cod, Haddock and Monkfish. Importantly, stocks of both cod and haddock are now accredited as sustainable by the Marine Stewardship Council.
Challenges remain in some parts of the country where the latest scientific evidence means further restraint is needed, for example in the Celtic Sea to revive stocks of haddock and megrim. However, there were increased quotas such as Western Skates and Rays (+15%), Bristol Channel Plaice (+49%), Sole (+9%) and Celtic Sea Cod (+11%). Crucially, a further package of measures has been agreed on sea bass in an attempt to reverse the decline around the English coast.
Total fishing opportunities worth more than GBP 750 million were agreed at this year’s negotiations, including increased quotas for:
North Sea: Cod +10%, Haddock +23% and Monkfish +20%. Irish Sea: Cod +377% and Haddock +55%. Eastern Channel: Sole +25% and Skates and Rays +20% Bristol Channel: Plaice +49% and Sole +9%
Australian rock lobsters are the best in the world but after they started to disappear from unlimited fishing, the government decided the expensive crustacean was going to be fiercely protected.
And that was the expensive lesson a number of Wollongong businessmen learnt yesterday after a judge in the coastal city handed down the biggest fines ever given for illegal fishing in NSW history.
The group of men, who were part of the fishing company that engaged in the major scam, the seafood restaurant that bought them and anyone associated with the crime, were fined a whopping AUD 2.1 million.
That sum is on top of court costs and the money lost on valuable lobster fishing shares.
The Maine Center for Entrepreneurial Development and its partners are expanding next year's Top Gun entrepreneurship program to include companies in the aquaculture sector.
MCED announced Monday that applications are now being accepted for Top Gun 2018, an entrepreneurship acceleration program that has helped more than 175 startups since 2009.
Partnering with the University of Maine, Gulf of Maine Research Institute, Maine Aquaculture Innovation Center and Lewiston/Auburn Economic Growth Council, MCED stated in a news release that the 2018 program will accept about 40 companies in total, about 10 companies in each of the 2018 locations: Portland, Bangor, Lewiston/Auburn and Brunswick.
CHENNAI - Deep sea fishermen need not feel lost any longer. The Indian Space Research Organisation (ISRO) has developed a satellite-enabled hi-tech communication device by which fishermen can stay connected up to 1,500 km from the shore without internet or tower connectivity.
The space agency is planning a commercial roll-out of the device in another couple of months and is popularising it among all coastal states.
The gadget, which will be fitted to the boats, will use NavIC (India’s own regional satellite navigation system) to lock the location of the boat and periodically update the location to the ground control room. Besides, the fishermen will receive text and video messages on ocean weather forecasts. If a low pressure area forms in the Bay of Bengal and is likely to intensify into a cyclonic storm, fishermen will be alerted in advance to take preventive measures.
