IN BRIEF - Crayfish survey defies Ministry spin - LegaSea
Tuesday, March 21, 2017
A landmark survey of people who pot and dive for crayfish on the northeast coast between Pakiri and East Cape defies Ministry for Primary Industries’ assurances that the fishery is doing well. More than three quarters (78.6%) of the 822 survey respondents described the size and availability of crayfish in this popular fishery as 1or 2 out of 7. Six per cent rated it as average, and only 2.2% described the fishery as above average.
Of those who took part, 83% supported or strongly supported a seasonal closure to all harvest to help the crayfish recover. Only 7% opposed or strongly opposed the move.
Some were willing to go even further, with 62% supporting or strongly supporting a total closure of the fishery for a fixed time, with a managed reintroduction of fishing once the fishery reopens.
A commercial crab fisherman has been fined CAD 15,000 for harvesting Dungeness crab in a closed area off Haida Gwaii in 2015.
Van Tan Le, skipper of the commercial crabbing vessel Vitamin Sea VI, pleaded guiltily to violating the Fisheries Act on April 10 of this year. The charges arise from Le having set more than 49 crab traps inside soft-shell management area 10—Mcintyre Bay closure area, north of Masset. A routine audit of the vessel’s logbook and electronic monitoring data later revealed possible fishing violations, which triggered a Fisheries and Oceans investigation in the summer of 2015.
In Prince Rupert court Judge Herman Seidemann III ordered CAD 14,000 of the total fine to be used for fisheries preservation and conservation projects in and around Haida Gwaii and the Hecate Strait.
In a press release, the DFO said they considered the offence extremely serious, as fishing during the closure could have detrimental impacts on commercial, First Nations and recreational crab stocks.
The critical habitat designation will require federal agencies to consult NOAA Fisheries if they operate or fund activities that may affect designated critical habitat in more than 3,968 miles of important coastal river habitat from Maine to Florida. Atlantic sturgeon was listed under the Endangered Species Act in 2012 and is comprised of the threatened Gulf of Maine distinct population segment and the endangered New York Bight, Chesapeake Bay, Carolina, and South Atlantic distinct population segments.
The ESA requires that NOAA Fisheries designate critical habitat when a species is listed as threatened or endangered. Under the ESA, critical habitat is defined as specific areas within the geographical areas that are occupied by the species, that contain physical or biological features essential to the conservation of that species, and that may require special management considerations.
The designation of critical habitat does not include any new restrictions or management measures for recreational or commercial fishing operations, nor does it create any preserves or refuges. Instead, when a federal agency funds, authorizes, or carries out activities that may affect critical habitat, it must work with NOAA Fisheries to avoid or minimize potential impacts to critical habitat. The activity of the federal agency may need to be modified to avoid destroying or adversely modifying the critical habitat.
CHENNAI - Fishermen can now receive weather alerts, information on potential fishing zones and tsunami warnings from scientists directly on their mobile phones.
Sagar Vani, a new software program from scientists at Indian National Centre for Ocean Information Services (INCOIS), Hyderabad, will help provide this information in all coastal languages, including Tamil, as well as in Hindi and English.
The researchers have also developed a mobile app for Android phones that fishermen can download to receive alerts before heading out to sea.
THE Petroleum Agency of South Africa (Pasa) has reportedly granted permission for seismic surveys to be undertaken to explore oil and gas along the East Coast.
The surveys, which would entail the use of sound energy to explore gas and oil in the ocean, have raised concerns over the environmental impact they would have.
Local fisherman since the age of 16, Sonny Chetty (78), was fishing at the Port Shepstone beach last week and said he had not caught anything that day and fishing generally was on the decline in the area.
Tasmania's two largest salmon producers will review research that linked the accelerated growth rate of farmed salmon to hearing deficiencies in up to 50 per cent of fish.
Researchers at the University of Melbourne found half of farmed salmon across the globe suffer from an inner ear deformity which can reduce their hearing sensitivity by up to 50 per cent.
Earlier research showed farmed salmon experience the deformity in vastly greater numbers than wild salmon, and the researchers have now linked the deformity to the accelerated growth rates of commercial salmon.
The study has been published in the Journal of Experimental Biology.
Muscat - Fish farming is not a modern concept – the Gunditjmara people in Australia’s south-west farmed eels for food and trade 6,000 years ago. Today Oman is looking to reel in capital to finance next-generation fish farming enterprises across the country.
Aquaculture, the practice of farming fish and shellfish, contributes to almost half of the world’s seafood production. And as fish populations drop and the world’s hunger for seafood continues to grow, aquaculture will become even more important.
According to Sajda al Ghaithy, media director at Ithraa, Oman’s inward investment and export development agency, aquaculture presents a significant opportunity to attract inward investment, create jobs, boost exports as well as enhance the country’s food security.
Rather it's a spa that is keeping 1400 tiny eels alive in the country's only eel rearing facility at the Foxton Wildlife Trust in Horowhenua.
Muaupoko iwi has set up a highly successful aquaculture programme, which is helping rejuvenate the population of tuna (longfin eel) in Lake Horowhenua, but when the temperature dropped in winter at the facility, so did the eel survival rate.
Robert Warrington has been working on the project since its inception, and was stumped as to why the eels began to die.
Aquaculture Systems Technologies LLC, a tenant at LSU Innovation Park, has won a USD 94,000 federal grant to demonstrate a waste control process for use in growing shrimp in small family-owned tank facilities.
About half the shrimp consumed worldwide are produced in ponds, Innovation Park officials said. The ponds depend on internally grown bacteria, known as biofloc, to reduce wastes produced by the shrimp and purify the water. U.S. farmers, who have been growing shrimp in tanks for niche marketing to sushi bars and restaurants, have difficulty controlling the unstable biofloc systems.
Aquaculture Systems produces floating bead filters that are used to purify water for aquaculture tanks, zoos and a variety of wastewater systems.
