摘要

Mark-recapture experiments on penaeid shrimp in the Gulf of Mexico have provided data on the growth, movement and life history of these important commercial species. Various tag and marking techniques have been used to study shrimp over the past twenty years with varying degrees of success. For long term growth, migration, and mortality studies an external tag was found to be superior. Mortality caused by the tagging procedure is a primary concern in mark-recapture studies. In field experiments, condition of the shrimp to be tagged may be an important factor, determining whether tagging affects mortality. Shrimp in poor condition show signs of visible necrosis (tissue degeneration) and/or recent ecdysis (soft exoskeletons) that make them more susceptible to damage from handling.
