Sexually Mature

New offspring due to sexual reproduction is not an instantaneous process from its birth, it takes time to be sexually mature. On the other hand, harvesting of commercially profitable fish population before the perfect size or weight is reached is not only a commercial loss but also risks the extinction of the population. Now, we discuss the issue of Ganges-Brahmaputra-Meghna basin, northern Bay of Bengal for the age-selective harvesting of Hilsa shad (Tenualosa ilisha) which lays eggs after its sexual maturation. Harvesting of hilsa before its sexual maturation risks its extinction and due to lamer body weight, it is not a commercially profitable policy. This is a reality of Sundarban estuary for hilsa fish harvesting, therefore, biologically and economically both India and Bangladesh are facing several problems. Empirical data of Frasergunje Fishing Harbor shows a clear picture as the supporting document of this mathematical problem.

Juvenile fishing of the migratory hilsa shad, Tenualosa ilisha (Hamilton, 1822), is rampant in the coastal waters of northern Bay of Bengal and associated Hooghly-Bhagirathi river system. The average annual economic loss due to this was estimated at `497.84 million (around US$ 7.8 million) necessitating urgent need for managing it to maximise benefits from the fishery as it forms a major fishery resource in the region. Factors leading to juvenile fishing and the possible solutions to control the resultant biological and economic loss are discussed.

Abstract Even before Bangladesh's submission on the outer limits of its continental shelf beyond 200 miles from its baseline reaches the head of the queue awaiting the attention of the Commission on the Limits of the Continental Shelf, the maritime boundary delimitations with Myanmar (2012) and India (2014) have produced a unique situation, in which Bangladesh's seabed boundaries have been fully delimited with both neighbours, creating a single continuous outer limit landward of the one submitted to the Commission. This may mean that there is no need to await the Commission's reaction to Bangladesh's submission, as there is nothing to stop Bangladesh simply beginning to exploit areas on its side of the two boundaries. This paper examines whether the position is really that simple, and whether any other state might have grounds for objecting if Bangladesh does so, together with deficits of co-operation that may confound early moves to exploitation.
