On September the 25th of 2019, the Intergovernmental Panel on Climate Change (IPCC) will release the first “Special Report on the Ocean and Cryosphere in a Changing Climate.” This report will compile the most advanced science on the severe consequences of climate change for the ocean and the millions of people who depend on ocean ecosystems. But fishermen across the United States don’t need to wait until tomorrow to see the effects that a warming world has on their livelihoods—they are living the effects of climate change every day.
Sixty-five percent of fishermen surveyed by CAP in 2015 believed that climate change could limit their profits and ultimately force them out of their fishery, and recent evidence supports their belief. For example, the Atlantic northern shrimp fishery has been closed for years because the population is below target levels due to warm water in the Gulf of Maine. Meanwhile, the lobster population from the once-thriving southern New England lobster fishery has dropped below minimum threshold levels, causing trap reductions and season closures, among other management measures. Dungeness crabbers on the West Coast experienced such severe losses linked to climate change in 2016 that they have sued fossil fuel companies.
Huon Aquaculture is positioned for a new growth phase after an eventful and sometimes very difficult year, chairman Neil Kearney says.
The Tasmanian-based salmon farmer's 2018-19 performance was hit by an extended run of warm temperatures affecting fish health and growth and moon jellyfish strike which killed some salmon and held back the growth of others.
"Whether farming on land or sea, the reality is that the environment exerts a significant influence over the capacity of any business to deliver growth in sales and earnings," Mr Kearney said in the company's annual report.
The Food and Agriculture Organization (FAO) of the United Nations has recognised Bangladesh as the eighth top fish producing country in the world.
Based on 2017 data, the Economist Intelligence Unit's regular publication World in Figure has published this recently.
According to the publication, Bangladesh produces 4.1 million tonnes of fish while China tops the list with 62.2 million tonnes of fish. Indonesia, India, Vietnam, USA, Russia and Peru are next on the list.
When Dave Kjelstrup landed an internship with the North Dakota Game and Fish Department in the mid-1960s as a UND biology student, there wasn’t much for fish in Devils Lake.
As a student of John Owen, a renowned UND fisheries professor who retired in 1986, Kjelstrup spent three summers working out of the old University of North Dakota Biological Station on Creel Bay, where he learned the fisheries trade from veteran Game and Fish Department biologists such as Dale Henegar and Al Kreil.
Devils Lake in those days was more of a duck slough than a fishing destination, Kjelstrup says, but he and his Game and Fish mentors occasionally would trap perch out of reservoirs in northeastern North Dakota and stock them in Devils Lake.
KIÊN GIANG — The C?u Long (Mekong) Delta province of Kiên Giang will expand marine aquaculture on an industrial scale in an aim to improve residents' income and protect the environment on islands and coastal areas from now until 2030.
The province plans to set aside zones for marine aquaculture in Phú Qu?c, Kiên H?i and Kiên Luong districts, Hà Tiên City, Long Xuyên Quadrangle and U Minh Thu?ng areas, according to its Department of Agriculture and Rural Development.
Nguy?n Van Tâm, director of the department, said the province would develop marine aquaculture in combination with fishery services and tourism.
The revelation, by the national broadcaster NRK, has sparked a major debate in Norway, with fishermen and environmentalists calling for action.
The country’s Directorate of Fisheries has admitted that the number of escapes has been rising year on year.
Last year, the figure was around 160,000, while in 2017 only 17,000 salmon escaped. Nesvik has expressed his concern at the rising numbers, but wants to hear from the industry what action it plans to take.
The communications manager of industry body Seafood Norway, Øyvind Andre Haram, agreed that the sector should have to pay when fish escape.
KHÁNH HÒA – Nha Trang City has set aside a zone covering 70ha of surface water in Nha Trang Bay for cage aquaculture, according to the city’s People’s Committee.
Located in the south-central province of Khánh Hòa, the city will focus on cage farming on Trí Nguyên and Bích Ð?m islands and a 50ha water surface area between Bích Ð?m and Ð?m B?y islands in Nha Trang Bay.
Under an aquaculture plan to 2035 in the bay, approved by the city’s People’s Committee, there will be 100 floating rafts with 2,931 traditional cages in Trí Nguyên and 30 floating rafts with 1,125 traditional cages in Bích Ð?m by 2025.
Scotland's Rural Economy Minister suggested on September the 19th of 2019 that he would intervene to accelerate fish farmers’ licence applications.
The current licensing system is a blockage to expansion that needs to be tackled head on, said Fergus Ewing, addressing the British Trout Association’s annual conference, held over two days in Stirling.
The minister expressed his frustration over what he called a ‘major problem’, and promised to lever his authority to try to achieve a solution.
In answer to a question from Alastair Salvesen, owner of Dawnfresh, the UK’s biggest trout farmer, Ewing said the issue had been raised often by salmon farmers.
Metal pollution from mines, mills and smelters is a hotly contested issue, especially when water passing through contaminated sites leaches metals into local waterways. The issue has become a major aggravation between miners and Indigenous peoples along many Canadian lakes and rivers.
Now Seabridge Gold of Toronto and the Gitanyow Fisheries Authority (GFA) are collaborating on a project applying ‘omic’ approaches to learn more about the impact of heavy metals on aquatic ecosystems. This method will apply environmental DNA (eDNA) to the potential effects of Seabridge’s proposed KSM copper-gold mine 65 km northwest of Stewart, British Columbia.
The project is funded by Genome BC and GFA, under the leadership of Dr. Vicki Marlatt at Simon Fraser University. The team will develop and implement eDNA methods to detect the presence or absence of fish species in the Nass watershed. They will also examine the costs of using eDNA compared to traditional, labour intensive visual or fish trapping surveys.
