"Bangladesh has a long coastal strip 710 km with abundant marine resources." We have found so far some 475 species of marine fish, 400 mollusc and 200 species of sea forest. Unfortunately some of them have disappeared, and many more are on the verge of extinction, "Prof Nani Gopal by Chittagong University Marine Biology Department told the news agency."
Johnius Coitor, Nematalosa Galatheae, Pseudapocryptes Gill openings, Thunnus Albacares, Thunnus Obesus and Xiphias gladius are the scientific names of some of the marine fish of different countries, including Bangladesh, have been included in the red list of the International Union for the conservation of nature (IUCN).
He said monsoon variations, frequent droughts and severe storms would also kill the fish in the Interior inland waters and their breeding patterns affect. "If significant impacts on the ecosystems, this would jeopardise an important food source in some coastal areas."
"Several fish as mentioned will be removed from these areas, if they adapt quickly to the changing salinity levels can not." "Fish are also very sensitive to temperature and some species - - can go locally extinct those who swim not far," he added.
The Bay of Bengal had a number of reasons behind the deterioration of ecological Prof. Gopal. These include sea temperature, increase in salinity, Habitat conversion of marine fish, massive resources, introduction of exotic species and commercial use or over hunting further increase.
According to international research by WorldFish with support of the British Department for international development (DFID), both coastal and landlocked countries in Africa, Malawi, Guinea, Senegal and Uganda, four Asian tropical countries - Bangladesh, Cambodia, Pakistan and Yemen, and two countries in South America, are Peru and Colombia, that economically vulnerable to the effects of global warming on fisheries.
