As Alaska's salmon season draws to a close, lots of fall fisheries are just getting underway from Ketchikan to the Bering Sea.
Southeast is one of Alaska's busiest regions for fall fishing, especially for various kinds of shellfish. Nearly 400,000 pounds of side stripe and pink shrimp are being hauled in by a few beam trawlers, and the season for spot shrimp opens Oct. 1. Usually about half a million pounds of the popular big spots are hauled up in local pots over several months.
Dungeness crab fishing also will reopen in Southeast in October, and up to 200 Southeast divers will head down for more than 1.7 million pounds of sea cucumbers starting October 1. A 140,000 pound sea cucumber fishery at Kodiak attracts around 20 divers and smaller cuke catches in the 5,000 to 20,000-pound range also occur along the Alaska Peninsula, the Aleutians and Bering Sea.
HCM CITY – The use of modern technologies in aquaculture would ensure sustainable development, experts said at a conference on water monitoring systems in HCM City on Thursday 20th of September 2018.
Hu?nh Qu?c Kh?i from the B?c Liêu Province Agricultural Extension Centre said that hi-tech in aquaculture, such as water monitoring systems or recirculating aquaculture systems, permits easier detection of anomalies and better control of fish farms.
It also requires less manual work and time, and is more environmentally friendly.
Phan Thanh Lâm of the Research Institute for Aquaculture No. 2 said that water monitoring systems were especially crucial for shrimp farming, as shrimp are highly susceptible to external factors such as temperature, pH levels and salinity.
The recreational advocacy group LegaSea is bitterly disappointed the Minister of Fisheries has deferred making decisive cuts to commercial catches of tarakihi on New Zealand’s east coast for at least another year. In October Stuart Nash will apply a 20% cut to the commercial catch, while LegaSea has been campaigning for a 65% reduction.
LegaSea spokesperson Scott Macindoe says the decision is a blow for the fishery as the 20% will be negated in some areas by the fishing industry’s ability to carry forward 10% of uncaught catch from the previous year. There are fears that commercial interests will succeed in keeping the stock low to maintain jobs in an unproductive fishery.
"It’s a body blow for one of New Zealand’s best loved fish. The fishery has been on the downward slide for 30 years. It is disappointing that Stuart Nash has decided on a 20% cut this year and only signaled further cuts in 2019, unless industry can deliver a "plan to rebuild the stock within 10 years." It is the Minister’s job to rebuild depleted stocks."
All of Malta’s five tuna farms have been fined for the occurrence of so-called ‘slime’ and other breaches of permit conditions over the past two months, The Sunday Times of Malta has learnt.
The Environment and Resources Authority (ERA) has been imposing daily fines on the farms.
For two months running, members of the ERA’s enforcement directorate have been conducting inspections on the fish farms on alternate days, covering north and then the south. On some days all farms were examined in a blitz of inspections.
Some of the farms have since come into line with environmental legislation while others are cooperating with the ERA to move towards compliance. Fines of up to EUR 70 daily are lifted as soon as compliance is achieved.
A test fishery for chinook salmon on the Fraser River this year is reporting dismal returns, raising new concerns for the endangered southern resident killer whales who rely heavily on these fish for their survival.
The federal government announced in May a reduction in harvest of chinook by roughly one-third and closures in some key whale foraging areas after declaring the southern resident killer whales are facing an imminent threat to their survival. The federal government acknowledges that lack of prey is one of the critical factors affecting the whales’ recovery.
But Misty MacDuffee, wild salmon program director for the Raincoast Conservation Foundation, said the daily results from the Albion test fishery on the Fraser had already demonstrated the need for a complete closure of both marine commercial and sport fisheries on chinook, in order to leave prey for the whales.
Amarin shares surged in Monday's premarket after the biopharmaceutical company's fish oil capsule showed dramatic benefits to heart patients in a clinical trial.
Amarin said its capsule, Vascepa, significantly reduced the risk of serious cardiovascular events over a placebo in trial results involving 8,179 statin-treated adults with elevated cardiovascular risk.
"We are delighted with these topline study results," John Thero, president and CEO of Amarin, said in a press release. The company said the trial met the primary endpoint with a 25 percent risk reduction.
Shares of Amarin were nearly 300 percent higher in premarket trading Monday 24th of September 2018, around USD 11.85 a share. By midmorning, the stock was up more than 220 percent.
According to a study published in the journal Pediatric Research, pregnant women can enhance the development of their unborn baby's eyesight and brain function by regularly consuming fatty fish during pregnancy. The findings suggested that infants whose mothers are fish three or more times a week during the last trimester of their pregnancy fared better than those whose mothers ate no fish or only up to two portions per week. According to the researchers, the results of the study suggest that frequent fish consumption by pregnant women is of benefit for their unborn child's development.
As per the researchers, this may be attributable to long-chain polyunsaturated fatty acids within fish, but also due to other nutrients like vitamin D and E, which are also essential for development. For the study, the research team analysed results of a small group of mothers and their children drawn from a larger study.
In the study, the mothers had to keep a regular food diary during the course of their pregnancy. Fluctuations in their weight before and during pregnancy were taken into account, along with their blood sugar level and blood pressure. The team recorded the levels of nutritional long-chain polyunsaturated fatty acid sources in the mother's diet and blood serum, and the levels in the blood of their children by the age of one month.
On a ship near the top of the planet, a 54-kilogram steel claw dumps out mud freshly scooped from the bottom of the sea. Jackie Grebmeier gets to work with a pair of tweezers, picking shrimplike critters called amphipods out of the muck.
Grebmeier has been digging up animals in the waters between Alaska and Russia for more than 30 years. And she has noticed a trend: A retreat has begun here at the edge of the Arctic. With temperatures rising, creatures such as amphipods have been inching northward. Meanwhile, clams and fish and whales from balmier climes have begun to move in.
"We're starting to see changes that we've never seen in the decades we've been studying this area," says Grebmeier, a biological oceanographer at the University of Maryland Centre for Environmental Science (UMCES) in Solomons.
New catch limits set for 32 fish stocks New Zealand
The commercial tarakihi (Nemadactylus macropterus) catch in the fisheries areas off the east coast of the North and South Islands is to be reduced by 20 per cent in an effort to rebuild the depleted stock.
