Metapenaeopsis sibogae (De Man, 1907) (Decapoda: Penaeidae Rafinesque, 1815) is distributed throughout the South Pacific and Southeast Asia gaining in commercial importance. There is, however, no study available on population biology of this species, which restraining our capabilities to design its sustainable management conservation protocols. We therefore studied reproductive M. delineate for first time ovarian maturation, size at sexual maturity, spawning season. Ovaries from females...

Saltmarsh and seagrass communities are coastal macrophytes. These perform a number of important ecological functions, one which is to support substantial fishery resources either as nursery ground or refuge from predators. The Bangladesh coast houses saltmarsh but there has been sparse information on the diversity fisheries adjacent these plant communities. Consequently, this study was carried out obtain shoot density biomass dominant (Porteresia coarctata) (Halophila beccarii) species...

Climbing perch Anabas testudineus is commercially important fish in Asian countries, mostly Bangladesh, China, India, Malaysia, Pakistan, Sri Lanka and Thailand. Also, it used as valuable food different countries of the world. Nevertheless, its natural populations are seriously declining due to heavy harvest, habitat destruction other ecological changes habitat. This paper recommends actions for conservation long-lasting isolated A. countries.

Amblypharyngodon mola Hamilton 1822 is widely distributed in the freshwaters of Southeast Asia and commercially important. We studied size at sexual maturity (TL50) A. addition to its fecundity indices using samples collected from Ganges River, Bangladesh.
