Assessment of Fish Production Potential of Certain Tropical Reservoirs

Abstract

In India, reservoirs are taking the prime resource as regards capture fisheries and extensive/ semi-intensive aquaculture and covering more than one percent of the country s land surface, in terms of resource size. These reservoirs are created by human activity and therefore host semi-natural ecosystems that can be manipulated in various ways and which already cover three million ha of surface area, are an increasing resource with vast potential for yield extension. newlineThe productivity of reservoir fisheries can be increased by using a number of approaches that combine better harvesting strategies, fertilization, carefully adapted stock enhancement and aquaculture. The natural biophysical constraints of reservoirs define their ecological production procedures, and their socio-economic settings shape the possibilities for human upliftment of production. In anticipation of the fisheries potential of the reservoirs, studies of reservoir characteristics that influence fish production, distribution and production as well as physico-chemical parameters which are temperature, pH, hardness, alkalinity, dissolved oxygen, Free carbon dioxide that could influence the production of the reservoir and play an important role in the biological productivity of a water body. newlineAquaculture is very much essential in the coming future to provide fish protein for ascertaining food security, to ensure socio-economic wellbeing through the generation of livelihood opportunities. Enhancement of productivity in relation to fish production is a very essential factor nowadays. Fish contains proteins and other nitrogenous compounds, lipids, minerals and vitamins and very low levels of carbohydrates and its biological composition shows that it is a good source of protein and essential fatty acids. newlineTo optimize the primary and fish production of some tropical reservoirs we selected five reservoirs of Mahoba district in Uttar Pradesh, India. Category wise all the reservoirs were small and medium and all are based in tropical regions. This study is bas
