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.
As the water and sanitation crisis on the Vaal River and its catchment escalates, two government departments have issued a joint statement denying a positive link between mass fish mortality and raw sewage flowing into the river.
Reports over the past weeks have shown fish kills as evidence of sewage discharge into tributaries on the north bank of the Vaal River, and linked that to health risks to millions of people and a constraint to development.
The presence of excessive levels of E.coli in the river is linked to disease outbreaks in especially poorer communities and threatens the phytosanitary status of export farmers who irrigate from the river.
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.
