Spatial and temporal extension of eutrophication associated with shrimp farm wastewater discharges in the New Caledonia lagoon.
Shrimp farming in New Caledonia typically uses a flow-through system with water exchange rates as a tool to maintain optimum hydrological and biological parameters for the crop. Moreover, the effluent shows hydrobiological characteristics (minerals, phytoplankton biomass and organic matter) significantly higher than that of the receiving environment. Separate surveys were carried out in a bay (...
متن کاملCharacterization of Shrimp Farm Effluents in Honduras and Chemical Budget of Selected Nutrients
The percentage of world shrimp production in Central America is only about 7% (Rosenberry, 1994), but the industry is important to local economies. In Honduras, over $70 million was generated by shrimp culture in 1994 placing the industry third in national export earnings. Sustainability of the industry is economically critical, and could depend on estuarine water quality. A 2-yr baseline of wa...
متن کاملBenthic macroinvertebrate susceptibility to trout farm effluents.
The direct effects of a Virginia trout farm on benthic macroinvertebrates were examined using multiple approaches. Static laboratory tests with the amphipod, Hyallela azteca, were conducted with exposures to water taken from a spring and from effluent both above and below a sedimentation basin. Onsite mesocosms were constructed to expose previously colonized artificial substrates to the same tr...
متن کاملIntegrated treatment of farm effluents in New Zealand's dairy operations.
Maintaining growth through intensification in the New Zealand dairy industry is a challenge for various reasons, in particular sustainably managing the large volumes of effluent. Dairy farm effluents have traditionally been treated using two-pond systems that are effective in the removal of carbon and suspended solids, however limited in their ability to remove nutrients. In the past these nutr...
متن کاملNutrient removal from farm effluents.
The objectives of the study were: (i) to examine the efficiency of nutrient removal during the treatment of dairy farm effluent in a two-pond system, and (ii) to produce an inexpensive but effective nutrient trap which could be recycled as a nutrient source or soil mulch. The concentration of chemical oxygen demand (COD), biological oxygen demand (BOD), nitrogen (N), phosphorus (P) and potassiu...
