IN BRIEF - Cooke Aquaculture collaborating on study to track sulphide levels on seabed near salmon farms
Tuesday, June 25, 2019
The consortium – led by Cooke Aquaculture and the Scottish Association for Marine Science (SAMS) with funding from the Scottish Aquaculture Innovation Centre (SAIC) – is exploring how measuring sulphides on the seabed could better track the impact of biomass from fish farms at six sites in Scotland and Canada, the SAIC wrote in a press release on Monday.
The study will be supported by Nova Scotia-based Dalhousie University, the University of the Highlands and Islands (UHI) and Fisheries and Oceans Canada (DFO) and the new approach is expected to monitor the impact of fish farms more quickly, accurately, and cost-effectively. The consortium is also consulting the Scottish Environment Protection Agency (SEPA).
Malta is paying too high a price for the fish farming industry, the Democratic Party said on Sunday as it hit out at large patches of slime blighting the coast.
In a statement, it observed that a consortium which owns a huge blue-fin tuna farm just off Comino was said to have applied for a PA permit.
"This is peak season for tuna fattening before slaughtering begins in October, and our coastal waters from Armier to Sliema are again polluted with slime. This is not naturally occurring foam, but slime. This time round, Comino has also been adversely hit," the party said.
Aquatic animal diseases are the most significant constraints to development and management of aquaculture. Aquatic animal diseases included non-infectious and infectious disease. An aquatic animal is highly affected by infectious diseases such as bacterial, viral, fungi and parasites. Viral aquaculture diseases are difficult to diagnose and control with the medication. No specific treatment is available for viral aquaculture diseases. Viral aquaculture diseases included infectious hematopoietic necrosis (IHN), viral hemorrhagic septicemia (VHS), channel catfish virus disease (CCVD), and infectious pancreatic necrosis (IPN). The aquaculture industry is a fast-growing industry but it’s facing major challenges such as prevention and treatment of diseases among shrimp and aquaculture species.
Advancement in the field of aquaculture therapeutics favors the growth of the viral aquaculture disease treatment market. Growing demand for the effective drug for the viral aquaculture disease treatment expected to boost up the growth of the market. Increasing incidence of viral infectious diseases among aquaculture species propels the demand for the viral aquaculture disease treatment therapeutics. Globally increasing consumption of fishes boosts up the growth of the viral aquaculture disease treatment therapeutics. Growing research and development in the field of veterinary medicines and increasing demand for aquaculture expected to favor the growth of the viral aquaculture disease treatment market. Increasing production of aquaculture species and growing government programs for animal health expected to propel the growth of the viral aquaculture disease treatment market. Moreover, strict regulation regarding the approval of new drug and vaccine expected to restrain the growth of the viral aquaculture disease treatment market. Unavailability of effective treatment option expected to hamper the growth of global viral aquaculture disease treatment market.
We applaud the government for its successful endeavours to increase fish production in the country—efforts that have resulted in Bangladesh ranking third in producing fish from inland water bodies, according to a report by the UN’s Food and Agriculture Organization (FAO) in 2018’. In the 2016-2017 fiscal year, Bangladesh produced a total of 41,34,000 metric tonnes of fish, including a first-time surplus of 84,000 tonnes. One of the ways this has been possible is by prioritising conservation of jatka (small hilsa) and other species through periodic bans on catching, transporting and selling fish from natural water bodies like the rivers and the sea. This ensures safe breeding and spawning of fish and helps to protect their fries. The bans, however, while significantly increasing fish production, have a detrimental effect on the fisher communities as their survival depends on the amount of fish they can catch and sell each day. During the bans, the fisherfolk are essentially jobless and fall into financial hardship.
At a recent seminar, discussants highlighted the need to help out the fishermen during these lean times when they cannot fish. Long-term planning is needed for this which would ensure alternative livelihoods and also provide adequate allowances to the fishermen and their families, most of whom are poor and lead miserable days during the ban periods. The government should start registering fishermen so that they can be properly monitored and assisted. The state minister for fisheries and livestock gave his assurance at the seminar that the irregularities in distribution of food during the ban periods have been reduced significantly in recent times which we hope is something that will be sustained.
The ghost netting Matt Waller hauled out of seemingly pristine waters near Boston Island, in South Australia last year was the last straw.
The tourism operator spends his days showing tourists the beauty of the islands south of Port Lincoln as they head out to dive with the ultimate ocean predator, great white sharks, or playful endangered Australian sea lions.
Mr Waller's workplace is dotted with isolated islands that have remained largely untouched since Matthew Flinders mapped the area in 1802.
The hunting ban started on 15 April 2019 and ended on 1 September. Fishermen said that this year's yield is less compared to 2018, said they could not find the hope.
Fishes decorating the stalls for about 15 days came to the citizens expensive, but argued that the prices of trades are not expensive. 200 years of fish stocks in 18 years, there was a reduction in the records of Istanbul University (IU) Faculty of Water Sciences Faculty Professor. Dr. Saadet Karakulak stated that anchovy and sardine will be abundant this year due to the deterioration in the ecosystem, but that large fish such as bluefish and acorn will be rare.
Professor Dr. Saadet Karakulak said that the most efficient and important sea in fishing is the Black Sea. Stating that 70 percent of hunting is in the Black Sea and there has been a serious decrease in fish stocks in recent years, Karakulak said, “There are many reasons for the decrease. One of them is over-hunting, illegal hunting and unregistered hunting. The impact of over-hunting and global warming is enormous. The increase in temperature leads to changes in the reproductive periods and migrations of fish along with the discharge systems. These have negative effects on fish. ”
The Beernaert family has been catching sole, turbot and monkfish in north-western Europe for at least three generations. But, because of Brexit, decades of seafaring could soon come to an abrupt end.
Benoit Beernaert, the owner of the Mare Nostrum trawler, makes half his annual catch in UK waters. And nobody knows whether his boat can continue to fish those seas after 31 October 2019.
“If I lose half my fishing ground why should I invest? It could be better to finish,” he said. Feelings don’t come into it: “I would finish, rather than go bankrupt. It’s a rational decision, it’s not an emotional decision.”
Commercial fishing of an important species of bait fish is going to be shut down in one of its key areas in New England for about six weeks.
Interstate regulators say the Atlantic herring fishery in the inshore Gulf of Maine is nearing a quota limit and will be subject to restrictions from Sept. 15 to Oct. 31 2019. That means fishermen will not be allowed to bring the fish to land until that date.
The inshore Gulf of Maine's an area that touches coastal Massachusetts, New Hampshire and Maine. Herring fishing's a major industry in New England, where the herring industry is centered. Fishermen sometimes catch more than 100 million pounds of the lobster bait fish in a year.
