Abstract

The use of the littoral oligochaete Pontodrilus bermudensis Beddard as a dietary supplement promotes maturation and spawning for a prolonged period in Feneropenaeus indicus, Penaeus monodon, P. semisulcatus, Portunus pelagicus, and Scylla tranquebarica. Thus, production of these worms in captivity will be useful for successful management of shrimp/crab hatcheries. To develop a culture protocol for this worm, different organic amendments were tested. Experiments conducted in plastic trays with a 2-cm-thick sand base, have revealed that out of four organic amendments (cow dung; cow dung + seaweeds; cow dung + leaf litter; and cow dung + hay) tested first three promoted multiplication of worms by 108.5%, 280.0%, and 230.0% , respectively, after 30 days. Subsequent experiments conducted in wooden crates with verminbed (12 cm intertidal sand + 5–6
