IN BRIEF - Krill found to break down microplastics – but it won't save the oceans
Wednesday, March 14, 2018
A world-first study by Australian researchers has found that krill can digest certain forms of microplastic into smaller – but no less pervasive – fragments.
The study, published in Nature Communications journal on Friday, found that Antarctic krill, Euphausia superba, can break down 31.5 micron polyethylene balls into fragments less than one micron in diameter.
The study was conducted in laboratory conditions with new plastics. The lead researcher, Dr Amanda Dawson, who completed the study as part of a PhD with Griffith University, said that it was likely that microplastics in the ocean would be even easier to digest because they had already been degraded by UV radiation.
The Zimbabwe Parks and Wildlife Management Authority (Zimparks) has introduced 100 000 kapenta fish in the Tokwe-Mukorsi Dam under the government’s ambitious command fisheries programme that will see the decentralisation of the pelagic and non-migratory sardine-like fish from Kariba Dam.
Zimparks spokesperson, Tinashe Farawo said the introduction of the kapenta in the country’s largest inland dam in Masvingo on Monday marks the beginning of the wildlife management authority’s effort to decentralise kapenta fishing and take it to the country’s 10 provinces.
“The project will be monitored by ecologists and if it succeeds, it will cascade to other dams in the country’s 10 provinces,” he said.
Kapenta, the freshwater, pelagic and non-migratory sardine-like fish flourishes in waters with a depth ranging from 20 to 40 metres under tropical temperatures between temperature of 21°C and 29°C and Farawo said the Tokwe Mukorsi Dam offers such conditions.
Peruvian seafood company Pesquera Centinela S.A. achieves Friend of the Sea's certification for fish meal and fish oil from Engraulis ringens fished in the South East Pacific Ocean (FAO Area 87) only by Friend of the Sea approved purse seine fleets.
Friend of the Sea's standard for sustainable fish feed, fish meal, fish oil and Omega-3certifies that the oil originates only from fisheries that are compliant with Friend of the Sea’ssustainable fishing requirements (including good fishery management, selective fishing gears and social responsibility) and that a full chain of custody is in place throughout the supply and production chain.
Pesquera Centinela S.A. operates as a subsidiary of The Romeo Group. The two audited processing plants are located at Tambo de Mora and Chancay, North of Lima. 58% of the raw material used for fish meal and fish oil comes from the company’s own fleet, whereas 41% from a third party fishing fleet, which is monitored by the Peruvian Government.
MEXICO CITY - A coalition of environmental groups has filed a lawsuit with the U.S. Court of International Trade, seeking a ban on Mexican seafood from the upper Gulf of California.
The groups say shrimp and fish imported from the Gulf endanger the vaquita porpoise, which are critically endangered.
Vaquitas have been decimated by nets et for the totoaba fish, whose swim bladder is considered a delicacy in China and commands high prices. Some nets set for shrimp and other fish may also endanger the species.
The Center for Biological Diversity and others said Wednesday the U.S. government has failed to ban seafood that endangers marine mammals, despite a petition and lawsuit filed in 2017.
PEMBROKE - The Maine scallop fishing season opened during the first week of December 2017 and now, with two weeks or less remaining, reports on how good a season it has been are decidedly mixed.
On the good side of the ledger, there seemed to be plenty of scallops, often in places where none have been seen for years, Melissa Smith, who coordinates scallop management for the Department of Marine Resources, said last week.
With the season ending for draggers on March 29 2018 along the Downeast coast (divers get six more days between March 30 and April 14), Smith said, only one of the seven rotational management zones that were open to fishing at the start of the season has been fully closed to fishing. Last year as the season ran down, only two of the seven rotational areas open at the season’s start remained fully open at its end.
From Southeast Alaska to the Bering Sea, Alaska halibut fishermen are gearing up to head out to sea as the 2018 halibut season opens at noon March 24. It's an annual ritual for both commercial fishermen and charter operators seeking to make their living through the pursuit of the tasty flatfish.
Out of concern for the health of the halibut stock, the 2018 Pacific halibut catch limits are lower and charter management measures are tighter compared to previous year.
PORTLAND, MAINE - Spring is in the air and baby eels are in the rivers. Or at least that's what Maine fishermen hope.
The state's big-money baby eel fishery is scheduled to get started on Thursday. Fishermen seek the eels, called elvers, in rivers and streams so they can be sold to Asian aquaculture companies as seed stock.
The elvers are frequently worth more than USD 1,000 per pound, and this year is expected to be especially lucrative because of supply issues elsewhere in the world. Maine is the only state in the U.S. with a significant elver fishery.
Boston, MA– Certified Quality Foods (dba Seafood Analytics), announces the introduction of Fishboard, a fully integrated electronic fish-monitoring device. Fishboard allows researchers, aquaculture farms, processors, at-sea observers, fishermen, and other participants in the seafood industry to quickly and easily measure and store important electronic information about fish.
With Fishboard, users can quickly and easily assess length, weight, health, condition, and degradation status and body composition of individual fish. The device displays real-time observation and storage of all measurements. Stored values can be used for comparisons, growth trends, reports, and analysis while real-time data can be used for immediate evaluation of individual fish health and growth. GPS, pictures and other data can also be added. Fishboard is the first device to market with all of these capabilities.
The measurable benefit is a simple-to-use electronic monitoring device that can assess physiological condition, nutritional status, and body composition of fish in real-time. The user-friendly design and usage of the machine allows anyone to measure, store and send valuable fisheries data. Dr. Keith Cox developed the device while on assignment with the National Marine Fisheries Service in Alaska, with applicability ranging from fishermen to research agencies. Funding for the research and development was through the North Pacific Research Board (NPRB).
