IN BRIEF - Up to 100% of breeding female eels dying in drainage pumps
Saturday, February 10, 2018
Documents obtained by Forest & Bird show that for decades, regional council drainage pumps have been brutally killing native eels as they attempt to swim to the ocean to breed.
The reports, created for Waikato Regional Council, contain grisly images of dead eels, many decapitated, with internal hemorrhaging due to high speed spinning, or with extensive spine damage.
At the time of its publication in July 2017, one report concluded that “currently … no pumps in NZ are likely to be ‘fish friendly’”, or safe for fish to pass through.
Forest & Bird’s Fresh Water Advocate Annabeth Cohen says the reports makes grim reading. “The potential scale of the crisis is horrifying. In some cases, all breeding female eels died as they passed through the drainage pumps."
Researchers aim to find out if it is a blip, or a sign that the stock is recovering after warming waters caused the stocks to crash.
Alaska's seafood industry was shocked last fall when the annual surveys showed cod stocks in the Gulf of Alaska had plummeted by 80 percent to the lowest levels ever seen. Prior surveys indicated large year classes of cod starting in 2012 were expected to produce good fishing for six or more years. But a so-called "warm blob" of water depleted food supplies and wiped out that recruitment.
European eels, besides being delicious, have mystified biologists for more than a century. They spend their adult lives in estuaries and rivers, and head to the Sargasso Sea near Bermuda to reproduce. Their tiny transparent larvae then hitch a ride back to Europe on the Gulf Stream. But eel populations have been mysteriously dropping, prompting desperate measures to replenish their numbers.
Now, researchers have a clue about one peril young eels face during their journey: hungry fish. The larvae were once considered too difficult for most predators to spot and catch, but a new study that looks at DNA traces in the guts of fish near eel-breeding waters suggests at least six marine species can make quick work of baby eels.
“The study shows that although eel larvae are likely difficult for predators to see, they do contribute to ocean food webs as prey for other species,” says Michael Miller, an eel expert at Nihon University in Fujisawa, Japan, who was not involved with the work.
KEETMANSHOOP – The //Karas region has great potential for fish farming, fisheries minister Bernhard Esau said during a fish harvest session at the Fonteintjie fish farm in Keetmanshoop on Saturday 18th of August 2018.
“I am very pleased to note that there is potential to start fish farming, aquaculture, here in //Karas,” he said.
Esau said the government is committed to developing aquaculture, especially fresh water aquaculture as, while not discounting mariculture, fish farming must happen where there is water.
The owners of an aquaculture enterprise in Stephenville say there is no need for them to add more sea cages to correspond with a planned expansion of their hatchery.
Northern Harvest Smolt, an affiliate of Marine Harvest, has registered plans to modernize and expand on the land-based salmon hatchery with the provincial government for environmental assessment.
The Newfoundland and Labrador Coalition for Aquaculture Reform, a group opposed to the project, issued a press release earlier this week that alleged Marine Harvest was illegally splitting the project by not also registering plans to expand its marine-based farming operations.
London - The Marine Stewardship Council (MSC) is proud to announce the five winners of the latest round of its scholarship program, including a project to study Arctic food webs, trials to monitor lobster stocks off the coast of Scotland and a project to monitor fish aggregating devices (FADs) in small-scale Indonesian tuna fisheries.
The program provides funding of up to GBP 4,000 per student to support research looking at environmental improvement, supply chain management or best practice in fisheries management. 2017’s winners have already started contributing to ocean sustainability, with their research providing new data and insights into the trade flow of octopus across East Africa, and the effectiveness of LED lights on turtle bycatch in Kenya.
MANILA – The 17th Congress will go on a 12-day break this August to allow President Rodrigo Duterte to sign an executive order (EO) reducing tariffs or taxes on imported fish and corn.
House Majority Leader Rolando Andaya was asked on Monday, August 13, why Congress will be suspending session from August 16 to 27. Under the legislative calendar, Congress usually opens a regular session starting July then adjourns for about a month from mid-October to mid-November.
"One of the reasons would be to allow the President to zero out or reduce the tariffs.... For now, [on imported] fish and corn," said Andaya, who is also Camarines Sur 1st District representative.
Authorities in the German city of Münster have been pumping millions of gallons of water into a lake in an effort to save local fish, as a searing heatwave kills algae vital to their survival.
Twenty tons of fish were found dead in Aasee lake earlier this week, victims of the unseasonably warm summer gripping much of Europe and North America. The extreme temperatures has killed the lake’s green algae, which produces oxygen required for the fish to survive.
According to Deutsche Welle, almost 925,000 gallons of oxygenated water were being pumped into Aasee each hour this weekend to push oxygen levels up and save the aquatic animals. The additional water supply will end on August the 13th of 2018.
PUTRAJAYA - The Fisheries Department has upgraded its analysis of antibiotics and tightened the Sanitation and Phytosanitary (SPS) measures as well as disease inspections at the country’s entry points following reports of freshwater prawns dumping recently.
The department, in a statement issued today, said a joint committee on import and export has been established by the Ministry of Agriculture and Agro-Based Industry together with the Ministry of Health, to discuss the issues from time to time, particularly when there was dumping of prawns from the neighbouring countries.
“The department will also implement monitoring and briefing programmes from time to time to the stakeholders and the public through the industrial consultative council to address this issue apart from acting as a facilitator to registered importers and exporters.
