Increasingly acidic conditions in the ocean—brought on as a direct result of rising carbon dioxide levels in the atmosphere—could spell trouble for the earliest stages of marine life, according to a new report in the August 5th issue of Current Biology, a publication of Cell Press. Levels of acidification predicted by the year 2100 could slash the fertilization success of sea urchins by an estimated 25 percent, the study shows. "If other marine species respond similarly—and there's...

With extension programmes, researchers can transfer their knowledge on aquaculture to end users for commercial fishing to save endangered species and even to harvest a commercially viable crop in ponds or coastal waters. Aquaculture occupies a strategic position in the economic development of India. The country is in the process of mordernising its fish production programmes, which in turn depends largely upon application of improved practices based on science and technology. This is...

Giant blue-fin tuna and other semitropical fish are increasingly being caught in South Korean waters, a phenomenon linked to global warming. At a fish market in Busan, three blue-fin tuna were put up for auction Thursday. The fish, 2.32-2.43 meters in length and 250-300 kilograms in weight, were caught near Jeju Island last Sunday. They fetched 3 to 3.1 million won each. They were the largest tuna caught off the southern coast in recent months. Korea had an unusually large number...

The project “Development of Marine Aquaculture and Assessment of Fishery Resources in the Andaman Sea, Thailand” is a follow-up to the Norwegian-Thai post-tsunami project of 2005-06. The Institute of Marine Research (IMR) is the key adviser to the project, which aims to enable the Thais to run fish farms that use modern aquaculture technology on their own. The project is being run by the Thai fisheries authorities in collaboration with IMR.

A boat towing a fish cage is business as usual on fish farms. But a cage towing a boat? That novel role reversal was on display recently in Culebra, Puerto Rico, as part of a project led by Cliff Goudey, director of MIT Sea Grant's Offshore Aquaculture Engineering Center (OAEC). Goudey conducted the tests at Snapperfarm, Inc., an offshore fish farm that has been growing cobia in submerged cages for five years. The spherical cage, developed by Ocean Farm Technologies, Inc. of Searsmont, Maine,...

The Chesapeake Bay’s blue crab population remained below the long-term average in 2007, according to a report approved by the NOAA-chaired Fisheries Steering Committee. The population of spawning-age blue crabs in the Chesapeake Bay in 2007-08 was 120 million, down from 143 million in 2006-07. The interim target population for spawning-age crabs is 200 million. “The science provided by the Blue Crab Advisory Report is critical as state resource managers make decisions...

Their prized terriers are given samba-dancing lessons, their choicest beef herds are treated to daily massages and now, in an effort to produce the most delicious sushi in the world, Japanese tuna are to be given acupuncture. The company in Osaka which patented the technique claimed that calm tuna thrashed about less in their death throes. Once the fish have received the brief treatment, the blood becomes purer and the flesh has a better flavour, Toshiro Urabe, the president of...

Tilapia is often touted as the single most important aquaculture product in the 21st century. In fact, Dr. Kevin Fitzsimmons, president of the World Aquaculture Society, called tilapia as the "food fish of the 21st century." Tilapia has been around since biblical times. Most of them were raised before in Africa, but accidental and deliberate introductions of tilapia into freshwater lakes made them feasible to be raised in tropical climate such as Indonesia, the Philippines,...

Reefs where fishing is not allowed are much less prone to infestation by the devastating crown-of-thorns starfish (COTS), according to a new analysis of AIMS’ long-term surveys of the Great Barrier Reef. AIMS scientist Dr Hugh Sweatman predicts that any future waves of COTS outbreaks will not be as destructive as the three waves that have affected the GBR since 1960, because the area of no-take zones on the GBR was increased from 4.5 per cent of the Reef to 33 per cent in 2004....

Scientists at Europe’s food safety watchdog have addressed the impact of various farming systems on the welfare of Atlantic salmon. Experts of EFSA’s AHAW Panel considered that the main factors affecting Atlantic salmon welfare are water quality, stocking density, diet and the process by which the fish are sorted by size (grading). In its risk assessment, the Panel produced a ranking system for potential welfare hazards in the various farming systems, which can be used by risk managers to gauge...

After two years of scientific collaboration and consultation, the Marine Stewardship Council (MSC) today launches its new Fishery Assessment Methodology designed to improve the quality and consistency of fisheries assessments, without either raising or lowering the ‘bar’ against which the performance of a fishery is assessed. The new Fishery Assessment Methodology is an addition to the existing MSC Fishery Certification Methodology (which defines the process for assessments), and will...

In August of 2004, new Virginia Tech Food Science Ph.D. recipient Fletcher Arritt presented his findings at the conclusion of his doctoral research. Dr. Arritt’s work was focused on the prevention of toxin production by Clostridium botulinum in fishery products. In his research, Arritt investigated the effects of different types of packaging for breaded and battered Alaskan Pollock fillets and raw flounder fillets. Different packaging techniques can have a pronounced effect on...

The international marine conservation group, Oceana, declared its concern regarding the breach of the deadline set by the Salmon aquaculture task force that should have, at the end of June, defined the way in which it would undertake the reduction of the use of antibiotics in the salmon industry, among others themes. The task force, called by the Minister of Economy, Hugo Lavados, with the purpose of identifying the problems that affect the salmon aquaculture industry and advancing in...

Scientists at Woods Hole are trying to train 5,000 hatchery-raised black sea bass to respond to a dinner bell for their meals, and one glance at sky-high supermarket fish-counter prices will explain why the researchers are willing to be the butt of jokes. The hope is that the fish, like Pavlov's dogs, will become so attuned to 20 seconds of programmed sounds that, even after they are released into the wild and eat many meals on their own, the signal will eventually draw them back into a...

Talking fish are no strangers to Americans. From the comedic portrayal of "Mr. Limpet" by Don Knotts, to the children's Disney favorite, "Nemo," fish can talk, laugh and tell jokes--at least on television and the silver screen. But can real fish verbally communicate? Researchers say, "Yes," in a paper published in the July 18 issue of the journal Science. Further, the findings put human speech--and social communications of all vertebrates--in evolutionary context. By mapping the...

Artificial reefs have been identified as among the means to boost the fish population and meet the national fish production target of two million tonnes a year. Fisheries Department director general Datuk Junaidi Che Ayub said it was among the measures taken to overcome a depletion of marine resources and prevent trawlers from encroaching the shoreline to catch fish. “This means of rehabilitating marine resources and habitats has proven effective. “It will...

The average American ate 16.3 pounds of fish and shellfish in 2007, a one percent decline from the 2006 consumption figures of 16.5 pounds, according to a NOAA’s Fisheries Service study. Americans consumed a total of 4.908 billion pounds of seafood in 2007, slightly less than the 4.944 billion pounds in 2006. The U.S. continues to be ranked the third largest consumer of fish and shellfish, behind China and Japan. Shrimp remained the top choice for seafood in the United States at...
