Abstract

Described is an automatic sampling device used to collect and preserve postlarval shrimp (Penaeus spp.). At timed intervals, seawater is pumped through collecting nets which retain samples of organisms including shrimp. A maximum of 12 samples can be collected in 24 hours. Each sample is preserved immediately in 10 percent Formalin. These samples may be removed once after each 24 hours of operation, or they may be accumulated with similar samples over a longer period of time. Comparison is made between catches with the automatic device and those made with the Renfro beam trawl.
