  • Breeding more uniform Nile Tilapia

    For fish farmers, uniformity of growth and body size is one of the key traits to be improved in future breeding programs. In domestic Nile Tilapia size differences among individuals are very large but the genetic background of this variability is almost entirely unknown. In a new study, published by Genetics Selection Evolution, researchers of Wageningen UR found that variability of harvest ...

  • For lively fish in the water

    For 30 years, trout have been cultivated at the Winkelmann farm in Wietzendorf (Lower Saxony), southeast of the city of Soltau. What started out as a hobby ultimately became a business. Since then, the main goal has been the preparation of fish eggs, caviar (roe). The female trout are brought up in concrete semi-circulating basins and slaughtered after 26 to 29 months as salmon trout. The annual ...

  • New approach to sustain `forage` fishing

    Reduced catches of small oceanic 'forage' fish like sardines and anchovies may be required in some ocean areas in order to protect the larger predators that rely on these species for food. This is a finding of the first major study of the ecosystem effects of fishing forage species: 'Impacts of fishing low trophic level species on marine ecosystems', reported today in the journal Science. Dr ...

  • Fish stocks boost for Yorkshire rivers

    Fisheries experts will be stocking 6,000 barbel at several locations in Yorkshire this week as part of the Environment Agency’s ongoing plans to develop and restore rivers in the region. All reared at the Environment Agency’s fish farm, 3,000 barbel will be stocked into the River Dearne at five locations between Barnsley and Adwick-upon-Dearne and 3,000 barbel will be stocked into the ...

  • ‘Genebank can save South Asian fish stocks’

    As South Asian fish stocks rapidly dwindle through overfishing, experts have suggested the setting up of a regional genebank as a remedy. Other suggestions that came up at a regional consultative workshop on management and dissemination of improved fish breeds to preserve their diversity in South Asia, held ...

  • Satellites help Colombian fishermen chase fish

    Fishermen in Colombia will be able to tap into the latest satellite information to chase shoals of fish in their depleted fishing grounds. Using satellites from NASA — the US-based National Aeronautics and Space Administration — and the European Space Agency, researchers from the National University of Colombia identified chlorophyll hotspots, which indicate the presence of the ...

  • Hormones in wastewater disrupt fish reproduction over generations

    Synthetic oestrogens in wastewater from contraceptive pills can have effects on fish reproduction and survival that worsen over several generations, new research has found. The study suggests that some fish populations may not be able to recover from levels of oestrogen pollution found in many freshwater environments. Freshwater ecosystems are increasingly under threat from both climate change ...

  • Fish stocks boost for rivers and lakes in the North East

    Fisheries experts will be stocking dace, chub, roach, crucian carp and rudd at several locations in the North East next week as part of the Environment Agency’s ongoing plans to develop and restore rivers and lakes in the region. One thousand chub and 2,000 roach are destined for the River Tyne at Prudhoe and a further 3,000 dace and 2,000 chub will be released into the River Team, ...

  • Mediterranean Fishing Nations Adopt Conservation Measures

    ROME, Italy (ENS) - Nations whose fishing fleets work the waters of the Mediterranean Sea have agreed on a series of new measures aimed at conserving the region's dwindling fish populations. The delegates also adopted new, stricter rules for tuna fishing in the face of warnings that illegal, unreported and unregulated fishing is wiping out the world's tunas. The measures were ...

  • First-ever federal rules for offshore fish farming issued

  • Aquaculture Water Quality Workshop Offers Tips to Boost Profitability of Fish Farming

    Healthy water leads to healthy fish and increases the potential for healthy profits for fish farmers. On the other hand, poor water quality can lead to stressed fish, increasing the chance for the animals’ illness and death, and resulting in income losses for farmers, says Matthew Smith, an Ohio State University Extension aquaculture specialist. Water quality management for fish farmers is ...

  • Fishermen, Communities need More than Healthy Fish Stocks

    The Alaska salmon fishery is touted as one of the best in the world. When measured with an ecological yardstick, it is – fish stocks are healthy and the fishery is certified by the Marine Stewardship Council as consistently meeting rigorous biological standards. Fish are individually counted as they swim upstream to ensure there are enough to breed. But Alaska salmon falls behind some of ...
