  • Assessing the risk to green sturgeon from application of imidacloprid to control burrowing shrimp in Willapa Bay, Washington. II: Controlled exposure studies

    The activities of two species of burrowing shrimp have a negative impact on the growth and survivalofoysters reared on intertidal mudflats in Willapa Bay and Grays Harbor, Washington. In order to maintain viable harvests, oyster growers proposed the application of the neonicotinoid insecticide imidacloprid onto harvested beds for the control of burrowing shrimp. In test applications, water ...

  • Assessing the risk to green sturgeon from application of imidacloprid to control burrowing shrimp in Willapa Bay, Washington. I: Exposure characterization

    Willapa Bay and Grays Harbor, Washington comprise the largest region of commercial oyster cultivation on the Pacific Coast. The activities of two species of burrowing shrimp impair growth and survival of oysters reared on the intertidal mudflats. In order to maintain viable harvests, the oyster growers have proposed controlling the shrimp by applying the insecticide imidacloprid onto harvested ...

  • 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. ...

  • Thailand: Successful intensive shrimp farming Thailand

    Historically, Thailand is one of the leading shrimp producing countries in the world. And, growing numbers of Thai farmers depend on AIRE-O2® aeration for water quality management. This major Penaeus monodon farm chose the AIRE-O2® aerators, 'for good oxygen transfer and horizontal flow for better circulation'. The manager reported, 'Daily operation of the farm is smoother due to easy ...

  • Use of Aquaclean in freshwater shrimp production

    The increase in popularity of freshwater shrimp (Macrobrachium Rosenbergii) production has prompted researchers to develop better and more efficient production methods. The current production methods are sufficient to justify the growing of freshwater shrimp, however, to stay competitive long term in the market place, producers will have to increase yields and reduce costs. Current niche markets ...

  • Alternative futures for Southern Bluefin Tuna

    This paper examines the outcomes of alternative management scenarios for the Southern Bluefin Tuna (SBT) fishery over the next 30 years. Two criteria are used to characterise outcomes: economic efficiency as measured by the present value of net benefits generated and conservation as measured by the predicted size of the spawning stock biomass in 20 years' time (SSB20). A bioeconomic model, ...

  • Species diversity and ecology of Tonle Sap Great Lake, Cambodia

    Abstract.  Tonle Sap Great Lake in Cambodia, the largest natural freshwater lake in southeast Asia, is situated within the floodplain of the Mekong River. Water levels in the lake vary by about 8 m between the dry season minimum and the wet season maximum when waters from the Mekong River back up the Tonle Sap River. The lake is highly productive – the annual fish catch from the Lake is ...

  • Valuation and Management of Fishing Resources Under Price Uncertainty

    The traditional expected-net-present-value methods cannot properly capture the management flexibility and strategic value aspects of a fishery, and may understate its value. Instead, this paper develops a Real Options model to conceptualize and evaluate fishery exploitation flexibility. Specifically, general models to value the opportunity to either exploit or invest in a fishery are presented. ...
