  • 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 ...

  • 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 ...

  • Much-in-demand common sole can now be reproduced all year round

    Common sole in the North Sea only spawns in April and May. Because the next generation of this much-in-demand fish cannot be reproduced well in captivity, it cannot be raised profitably in fish farms. However, researchers at IMARES Wageningen UR managed to select the conditions for farm-raised sole in such a way that the fish started reproducing even outside the season. By selecting the right ...

  • What`s for dinner? Genetically engineered salmon OK`d by FDA

    What's for dinner? Before long, it may well be genetically modified salmon, the first such altered animal cleared for human consumption in the United States. Critics call it "frankenfish," but the Food and Drug Administration granted its approval on Thursday, saying the faster-growing salmon is safe to eat. It could be available in a couple of years. "There are no biologically relevant ...

  • Floating vegetative mats may help clean fishery wastewater

    The feasibility of using floating vegetation to remove nutrients from fishery wastewater is being tested by Agricultural Research Service (ARS) scientists. The researchers' long-term goal is to develop a system to treat the wastewater, return it to ponds for reuse, and use the nutrients to produce biomass or plant material. The floating mats act as filters to remove the nutrients from the water. ...

  • New Species Recovery Credits Intended to Offset Harm

    The U.S. Fish and Wildlife Service is seeking public comment on a new program designed to help federal agencies conserve imperiled species on non-federal lands while allowing them to suffer harm on federal lands. The recovery crediting system gives federal agencies flexibility to offset the impact of their actions on threatened and endangered species on federal lands by undertaking conservation ...

  • Surrogate sushi: Japan biotech for bluefin tuna

    Of all the overfished fish in the seas, luscious, fatty bluefin tuna are among the most threatened. Marine scientist Goro Yamazaki, who is known in this seaside community as "Young Mr. Fish," is working to ensure the species survives. Yamazaki is fine-tuning a technology to use mackerel surrogates to spawn the bluefin, a process he hopes will enable fisheries to raise the huge, torpedo-shaped ...
