Fumonisins - mycotoxins of increasing importance in fish - Aquaculture - - 03/07/2009: "Fumonisins are a group of recently discovered mycotoxins which belong to the family of Fusarium toxins. The contamination of feedstuffs with mycotoxins poses a serious threat to the health and productivity of animals and cause great economic losses. In the USA, the annual losses caused by mycotoxins in grain production are estimated at 900 million dollars. Dependent on type of animal, sex, age as well as the nutritional and health condition of the animal, fumonisins cause different clinical symptoms. Additionally, the occurrence of several mycotoxins in feed is very likely and can amplify the toxic effects of the individual toxin (synergistic effect)."

Successful artificial tuna breeding in Europe

Successful artificial tuna breeding in Europe

World-first breeding techniques pioneered by Clean Seas Tuna Limited to artificially reproduce Southern Bluefin Tuna have been successfully replicated in Europe. European research consortium Allotuna has reported productive spawning of Atlantic Bluefin Tuna - the SBT's northern cousin - using the same strategy conceived by...

Scientists Integrate Data in Three Dimensions Across Coastal Seascapes to Study Climate Effects on Young Fish


From the surface, the two areas of ocean off the coasts of northern New Jersey and Long Island, New York look the same. But to NOAA scientists, the four-square-mile patches could not be more different as they view real-time underwater images and environmental data to try to figure out what...

Chemicals make farmed fish taste like ocean fish

Chemicals make farmed fish taste like ocean fish


An aquaculture company has used artificial flavorings to give its farmed fish the taste of wild-caught pollock. 'It met 10 out of our 10 taste parameters,' said Norbert Sporns, president and chief executive officer of HQ Sustainable Maritime Industries (HQSM). HQSM has signed a joint development agreement with the Beijing division of...

Scientists Find Bird and Human E. coli in Wild Fish


Scientists at the University of Minnesota have found that some of the potentially harmful bacteria in the Duluth-Superior Harbor come from an unlikely source: the fishes. It's not the fishes' fault, though. They are just carrying around bacteria that are already in their environment...

Census of Marine Life lists 122,500 known species, over halfway to complete inventory by Oct. 2010


World Register of Marine Species inaugurated with first 122,500 validated names; over 56,000 aliases for ocean species identified. Census of Marine Life-affiliated scientists consolidating world databases of ocean organisms have demoted to alias status almost one-third of all names culled from 34 regional and highly specialized inventories. The new...

Does oxygenation of fresh water induce cataracts in salmon after sea transfer?

Does oxygenation of fresh water induce cataracts in salmon after sea transfer?


Farmed Atlantic salmon in the fresh water stage are supplied with extra oxygen to maintain well-being and growth. Recent trials carried out by NIFES have shown that oxygenated water in this life stage can lead to cataract development in the sea water stage. Farmed Atlantic salmon can develop cataracts, which are malconditions in the eye. In...

Aquatic Weed Control: Using Grass Carp by Dr. Martin W. Brunson

Aquatic Weed Control: Using Grass Carp by Dr. Martin W. Brunson, Extension Leader/Fisheries Specialist - Mississippi State University Extension Service Information Sheet

Carp, or white amur, have been used for aquatic vegetation control in Mississippi for the past two decades. These fish, used as a 'biological control' for aquatic vegetation, can be effective and cost efficient when stocked at appropriate rates and when the problem-weed species is a plant preferred by carp. Although these fish are voracious herbivores, they exhibit preferences for...
