  • Study: Wastewater treatment improves fish health

    A decade-long study by Canadian researchers concludes that improved water treatment benefits fish populations. University of Waterloo researchers found that within a year after an upgrade to one of the area’s municipal wastewater treatment plants, there was a 70 percent decrease in the occurrence of intersex fish in Ontario’s Grand River. Within three years there was a full recovery ...

  • The effects of surface water abstraction for rice irrigation on floodplain fish production in Bangladesh

    Abstraction of surface water for irrigation poses a serious threat to the sustainability of floodplain fisheries in Bangladesh. Previous fisheries research has accorded a central role to dry-season (Rabi) water maintenance in safeguarding the health of the fishery, but rice irrigation water abstraction dries up water bodies at a rapid rate. Having reviewed various aspects of this water ...

  • Assessing The Health of Marine Ecosystems Through Fisheries Data

    Ecosystem Health Assessment (EHA) started to be applied in environmental management in the late 80s. Since then, a considerable number of ecological indicators have been applied for EHA. Jørgensen et al. (2005a) have classified these indicators into eight levels corresponding to: indicators based on specific ...


  • The Effect of Creosote on Vitellogenin Production in Rainbow Trout (Oncorhynchus mykiss)

    Abstract  As part of a broader investigation into the effects of creosote treatments on the aquatic biota in pond microcosms, we examined the possible implications for vitellogenin (Vtg) production in Oncorhynchus mykiss [rainbow trout (RT)]. Vtg is the precursor of egg yolk protein and has emerged as a useful biomarker of exposure to estrogenic substances. Our a priori intent was to assess ...

  • Bioaccumulation and distribution of perfloroalkyl acids in seafood products from Bohai Bay, China

    Ten perfluoroalkyl acids (PFAAs) were measured in the seafood collected from Bohai Bay, China, in 2010. The summed concentrations of the PFAAs were in the ranges of ND–194 and 4.0 to 304 ng/g dry weight for invertebrates and fish, respectively. The levels of perflurooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) in the seafood were lower than those from North America, the Mediterranean ...

  • Overfishing Threatens Critical Link in the Food Chain

    The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten ...

  • Toxicity of forest fire retardant chemicals to stream‐type Chinook salmon undergoing parr–smolt transformation

    Long‐term fire retardants are used to prevent the spread of wildland fires. These products are normally applied by aircraft and are intended specifically for terrestrial application, but fire retardants have entered aquatic habitats by misapplication and/or accidental spills and have resulted in fish mortalities. The authors examined the toxicity of two fire retardant products, PHOS‐CHEK 259F ...

  • Rising Meat Consumption Takes Big Bite out of Grain Harvest

    http://www.earth-policy.org/data_highlights/2011/highlights22 World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption. ...
