Abstract

The distribution, size composition and feeding ecology of Penaeus monodon in the coastal waters of Tungkang, Taiwan, were studied from July 1982 to August 1985. Gravid female shrimp are found inshore and offshore at depths between 10 and 40 m from June to December. Spawning peaks occur in August and November. Juveniles and subadults are found in the Kaoping, the Tungkang and the Linpien estuaries from March to May. Emigration of subadults from Dapong Bay occurs mainly from June to October. Subadults and adults are caught in appreciable numbers in coastal waters between Dapong Bay and Nanshufu at depths less than 40 m from June to January with the peak from July to October. The stomach contents of the shrimp are mainly composed of crustacea, molluscs, fish, detritus and sand granules. Seasonal and geographical variations in stomach content compositions are significant.
