If bycatch rates are high, collecting seedstock for aquaculture operations can have very large consequences for wild fisheries. For example, milkfish constitute only 15% of total finfish fry collected inshore by seine net the remaining 85% are discarded and left to die on the beach. The 1.7 billion wild fry stocked annually in Philippine milkfish ponds thus result in a loss of about 10 billion fry of other finfish species. In India and Bangladesh, up to 160 fish and shrimp fry are discarded for every fry of the giant tiger shrimp, Penaeus monodon, collected to stock shrimp ponds. The magnitude of annual fry bycatch is estimated at 62 million to 2.6 billion in three collecting centres in West Bengal, India.
