Benefits of Shrimp Stock Improvement: A case study of the U.S. shrimp farming industry

摘要

IN MANY shrimp farming regions of the world, farmers still rely on the capture of wild shrimp to stock their ponds. Shrimp are caught as postlarvae and stocked directly for growout or as broodstock which are subsequently spawned in captivity to provide seed. Negative environmental consequences of this activity are not well documented, although there are concerns that harvesting wild shrimp for aquaculture purposes can deplete local shrimp populations. In addition, incidentally caught organisms (by-catch) may be captured with the target shrimp during collection, and this by-catch usually is discarded because there is no economic incentive to process, release, or save it.
