IN BRIEF - 500 Species Of Fish Change Sex In Adulthood: Researchers
Monday, July 15, 2019
WASHINGTON - Five hundred species of fish change sex in adulthood, often in response to environmental cues, researchers have found.
"I've followed the bluehead wrasse for years because sex change is so quick and is triggered by a visual cue. How sex can reverse so spectacularly has been a mystery for decades. The genes haven''t changed. So it must be the signals that turn them off and on," said Prof Jenny Graves, one of the researchers of the study.
Bluehead wrasses live in groups, on coral reefs of the Caribbean. A dominant male with a blue head protects a harem of yellow females. If the male is removed, the biggest female becomes male in just 10 days. She changes her behavior in minutes and her color in hours. Her ovary becomes a testis and by 10 days it is making sperm.
Hundreds of fishery stakeholders and scientists will gather in Anchorage next week as the state Board of Fisheries begins its annual meeting cycle with a two-day work session.
The seven-member BOF sets the rules for the state’s subsistence, commercial, sport and personal use fisheries. It meets four to six times each year in various communities on a three-year rotation; this year the focus is on Kodiak and Cook Inlet.
The fish board and the public also will learn the latest on how a changing climate and off-kilter ocean chemistry are affecting some of Alaska’s most popular seafood items at an Oct. 23 2019 “talk and Q&A” on ocean acidification (OA) in Alaska.
KUALA LUMPUR - The government plans to strengthen the nation’s maritime enforcement assets in an effort to curb encroachment by foreign fishing boats which resulted in Malaysia losing up to RM5 billion in fisheries revenue every year, the Dewan Rakyat was told.
Agriculture and Agro-based Industry Minister Datuk Seri Salahuddin Ayub said the ministry would submit the proposal to the Cabinet, which includes a suggestion to purchase a mother ship to facilitate enforcement operation at sea.
“Prior to this, the government has taken firm action by carrying out an operation dubbed ‘Ops Naga’ and will continue doing so with the commitment from three ministries, namely my ministry, the Home Affairs Ministry and Defence Ministry.
KUALA TERENGGANU - The fish stock in the country's territorial waters is now getting less and the size is getting smaller due to human greed.
Universiti Malaysia Terengganu (UMT) Fisheries Gear Technology and Fisheries Ecology senior lecturer Dr. Mohd Fazrul Hisam Abd Aziz said fishermen were able to get mega-sized fish easily 15 years ago compared to the present situation and it was one of the signs of the level of pressure on the country's fisheries stock.
One of the reasons for stock loss was illegal fishing, unreported and uncontrolled (Illegal, unreported and unregulated (IUU)) fishing.
PONTIAN - The Ministry of Agriculture and Agro-Based Industry (MOA) has asked the Fisheries Research Institute to conduct a feasibility study on a new location for the caged fish breeding industry in Kukup near here.
Its deputy minister Sim Tze Tzin said the study which will cover several criteria including the depth of sea water, the oxygen content and the quality of water, is a long-term effort to help revive the sector.
This follows a recent incident in August when 44 fish breeders lost RM5 million after thousands of their stock died due to water pollution which occurred after the Lekima typhoon struck.
Gustav Witzøe will take over as CEO of SalMar effective 21 October 2019. From this date the current CEO, Olav Andreas Ervik, will become managing director of the new subsidiary SalMar Ocean AS and responsible for the company’s ventures in ocean-based fish farming.
SalMar’s initiatives in ocean-based fish farming has to date been organised as a business area within SalMar and headed by Gustav Witzøe. These activities will now be transferred to a subsidiary which Ervik wanted to lead.
Both Witzøe and Ervik emphasise that this change will ensure continuity in management and that it is a logical consequence of SalMar’s ambition to lead in the development of ocean-based fish farming.
As part of a rebranding campaign, the Global Aquaculture Alliance on Oct. 16 2019 launched a redesigned Best Aquaculture Practices (BAP) website. The refreshed BAP site is more consumer-facing, peppered with messaging that better explains the depth and comprehensiveness of the industry-leading third-party aquaculture certification program.
The new BAP site is anchored by the new BAP logo, unveiled on July 25 as the first step in a multi-step rebranding campaign that’s officially being rolled out this month with the launch of the redesigned BAP site. The rebranding campaign acknowledges the BAP program’s journey from an industry-facing solution to a publicly recognized brand.
Among the features of the new BAP site is a marketing toolkit containing assets for retailers, foodservice operators and consumers, encouraging consistent messaging about the BAP program. The new BAP site also contains a new “Where to Find” page with retail and foodservice endorser logos that are sortable by region and segment as well as a new “Our Logo” page with information about the new BAP logo.
