Distribution of decapod larvae in the Bombay Harbour-Thana-Bassein Creek regions

Variations in the abundance and composition of larval decapods were studied from 90 km stretch of the Bombay Harbour-Thana Creek-Bassein Creek (BHTCBC) system for a period of 15 months. The larvae belonged to Penacidea, Caridea, Anomura and Brachyura. Among these, brachyurans were the most abundant in the entire study area indicating good potential for crab fishery. Penaeus, Metapenaeus and Parapenaeopsis were the genera recorded in the family Penaeidae of which Metapenaeus spp. were the most common. Generally there was a higher abundance of Penaeus and Metapenaeus during monsoon probably indicating intense breeding. A few genera of decapods showed patchy occurrence in this system. Results of this first investigation were quantitatively and qualitatively evaluated with comments on fishery potential of the commercially important groups of decapods.
