The diversity of fish consumed in Bangladesh is a key aspect of diet and culture. Although total fish production in Bangladesh has been rising due to aquaculture, there are widespread concerns for loss and overexploitation of floodplain capture fisheries. The two are not effectively the same, because the resulting diversity of fish differs under each circumstance, as does access to fish and res...

The explosion of the Chernobyl Nuclear Power Plant resulted in some of the most radioactively contaminated habitats on earth. Despite evacuation of all human inhabitants from the most contaminated areas, animals and plants continue to thrive in these areas. This study examines the levels of contamination and genetic damage associated with radiocesium in catfish (Ictalurus punctatus) from the co...

Food and habitat are important environmental factors, which play significant role in the physiology of fish. The present experiment was conducted to ascertain effects food on hematological parameters rohu Labeo rohita reared from first feeding pond with natural foods aquarium using formulated feed for three months (90 days). Fish were sacrificed after rearing period hemato-biochemical (hemoglob...

The population of Bangladesh is increasing tremendously and to keep pace with the increasing demand of fish protein, farmers intensified fish production from the water bodies which created environmental pollution. To tackle the situation the raft and rack aquaponics experiment was conducted to reduce the water pollution and have vegetable production from high density poly-culture fish ponds. Th...

Organisms are exposed to strong selective pressures from several sources, including predators and pathogens. Response to such interacting selective pressures may vary among species that differ in life history and ecology in predictable ways. We consider the impact of multiple enemies (fish predators and trematode parasites) on the behavior of larvae of three anuran species (Lithobates (=Rana) s...

Salt evaporation ponds have played an important role as habitat for migratory waterbirds across the world, however, efforts to restore and manage these habitats to maximize their conservation value has proven to be challenging. For example, salinity reduction has been a goal for restoring and managing former salt evaporation ponds to support waterbirds in the South Bay Salt Pond Restoration Pro...

Propagule pressure and habitat characteristics are important factors used to predict the distribution of invasive alien species. For species exhibiting strong propagule pressure because of human-mediated introduction of species, indicators of introduction potential must represent the behavioral characteristics of humans. This study examined 64 agricultural ponds to assess the visibility of pond...

Ecologists have long realized that stable species richness values can mask rapid turnover in species composition. Because turnover occurs as a consequence of both local and regional processes, understanding the responsible factors provides insight on processes influencing community structure at different scales. Despite the insights to be gained from data on species turnover, they remain relati...

Two experiments were conducted in 200-m earthen ponds at Asian Institute of Technology, Thailand, for 87 days to test the feasibility of an integrated pen-cum-pond system, which utilizes wastes from intensive culture of hybrid catfish (Clarias macrocephalus C. gariepinus) as nutrients for semi-intensive culture of Nile tilapia (Oreochromis niloticus). This integrated pen-cum-pond system enhance...
