Type: Journal Article
The integration of paddy cultivation with prawn/fish culture can become a viable alternative to effectively utilize the vast area of derelict polders (embanked coastal flood plains) in Kuttanad, India. Nearly 55 000 ha of ...
Some aspect of population dynamics of three penaeid shrimp (P.monodon, P.semisulcatus and M.monoceros) from the Bay of Bengal, Bangladesh.
Type: Journal Article
In the Bay of Bengal of Bangladesh area the values of asymptotic length (La) for tiger shrimp (Penaeus monodon), green tiger shrimp (Penaeus semisulcatus) and brown shrimp (Metapenaeus monoceros) were found to be 30.0 cm, ...
Efficacy of chemical markers and physical tags for large-scale release of an exploited holothurian.
Type: Journal Article
Hatchery-produced juveniles need to be distinguished from wild conspecifics in order to evaluate the success of restocking experiments and stock enhancement. The commercially valuable sea cucumber Holothuria scabra, or ...
