The investigation was carried out in two river-estuaries of Khulna district from March 1998 to February 1999, to assess the abundance of black tiger shrimp (Penaeus monodon) post larvae IPL) and to quantify the damage to diffe-ent aquatic organisms during collection of P monodon PL. It was observed that about 384 larvae of other shrimp species, 208 fin-fish and 835 other macrozooplankton were destroyed during the collection of only one PL of P monodon. During the experimental period 0.53 million man days/ year were estimated to be involved in shrimp fry collection and on average 59.0 millionP. monodon PL were collected annually from the surveyed areas. The study implies that mass destruction of valuable aquatic organisms by shrimp seed collectors is a serious threat to biodiversity and coastal ecosystem integrity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
