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 ...

  • Aided by the Sea, Israel Overcomes an Old Foe: Drought

    A hefty tax was placed on excessive household water consumption, penalizing families with lawns, swimming pools or leaky pipes.

  • Increased oestrogen pollution in European rivers could affect development of brown trout

    Brown trout (Salmo trutta) embryos exposed to oestrogen during development hatched earlier, grew more slowly and had a lower heart rate than unexposed individuals, according to a recent Swiss study. These findings may indicate that oestrogen pollution in some European rivers is contributing to the decline of wild populations of such species. Endocrine disrupting compounds (EDCs) affect ...

  • 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.

  • 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 ...

  • Pesticides may affect all stages of aquatic life

    Ecotoxicity tests that are used to understand the impacts of chemical pollutants on aquatic organisms and ecosystems could be improved by including all life stages of the test animals. These are the conclusions of a study by Belgian researchers, who found that the apparent absorption of some pesticides by the dormant eggs of water fleas may have negative effects on the invertebrates’ later ...

  • Ethanol`s rise can mean loss of hunting lands

    Pheasants once drew hundreds of weekend hunters to Fairbury, Neb., each fall, filling the 45 rooms at Randy Brown's Capri Motel with sportsmen eager to bag their limits. But times have changed. The native grasslands and milo crops that used to dot surrounding Jefferson County have been overtaken by corn and soy crops. Neither provides the shelter that wildlife once enjoyed. This year's opener ...

  • Sting operation - jellyfish `blooms` may endanger fish stocks

    Surges in jellyfish populations may be one reason for a drop in fish stocks observed in the Mediterranean and Black Sea, according to a new report published by FAO. Overfishing, which removes top predators from the sea, is one of the factors behind jellyfish "blooms", or suddenly increased numbers. A "vicious circle" can then follow in which large numbers of medusae feed on fish larvae and ...

    In recent years, one part of the food business has rivaled organics as the hot growth area: "local" food (defined vaguely as coming from the same state or from less than 100 miles away, for example). It's a market segment that has just about doubled in sales and number of outlets over the last ...
