  • Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries

    The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

  • Nets That Save Fish - Ocean bycatch isn’t inevitable — it’s a design challenge.

    Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t ...

  • Evaluation of management strategies in Ningaloo Marine Park, Western Australia

    The spatial, multi-species nature of coral reef fisheries makes them notoriously difficult to manage. We have developed a simulation modelling approach to examine the effect of management options on the recreational fishery of Ningaloo Reef in Western Australia, that targets Spangled Emperor ( Lethrinus nebulosus ) model. Results show the effects of historical fishing mortality on the ...

  • 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 ...

  • Vulnerability of freshwater fisheries and impacts of climate change in south Indian states economies

    We compare the vulnerability of five states in India national economies to potential climate change impacts on their capture fisheries using an indicator-based approach. States in India (e.g., Karnataka, Tamilnadu, Andhrapradesh, Kerala and Maharashtra) were identified as most vulnerable. This vulnerability was due to the combined effect of predicted warming, the relative importance of fisheries ...

  • Case study: Fish farm

    OverviewKfar Ruppin is one of the leading fish farming coops in Israel. Recent restrictions on water consumption and discharge have led the coop to consider semi intensive closed loop fish ponds. The main objectives in closed loop fish farming applications are prevention of Ammonia and Nitrite accumulation, and removal of suspended solids. Usually, the investment in a closed water cycle system ...

  • Expanding marine protected areas to restore fisheries

    After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand. In response, the oceanic fish catch climbed from 19 million tons ...

  • Damage to Cauliflower Coral by Monofilament Fishing Lines in Hawaii

    Abstract: Many fishing methods and gear types used in coral reefs cause physical damage to the reef substratum. Only recently have monofilament fishing lines been recognized as a cause of coral damage and death. We assessed the extent of damage caused by monofilament fishing lines to the cauliflower coral ( Pocillopora meandrina) colonies in fished and adjacent ...
