Question

how can we effectively conserve the fish population?

Answer 1

Fishes exhibit enormous diversity in size, shape, biology and in the habitats they occupy. The great majority comprises bony fishes, mainly teleosts. In addition, there are around 800 species of cartilaginous and 70 of jawless fishes (lampreys and hagfishes). It is believed that out of 4000 species of vertebrate recognised world over 22000 are fish species; of which 8411 are fresh water while 11650 are marine.  As per the report more than 24500 fin fish species exist throughout the world. However, there is prediction of around 28500 fish species representing more half of the vertebrate diversity. They surveys emphasised that there could well be at least 5000 species more to be discovered.

In India 2163 species of finfish have been recorded from upland cold (157; 7.26%), warm waters of the plain (454; 20.99%), brackish water (182; 8.41%) and marine environment (1370; 63.3%).In terms of habitat, fishes live in almost all conceivable aquatic habitats, ranging from Antarctic icecap to hot springs as well as fresh to saline waters. As per the FAO, a sustainable fisheries development envisages an eco-friendly, equitable mode of development that can sustain livelihood over generations. An attempt has been made to assess the current status of fish biodiversity, delineate the threatened species of India vis-a - vis their causative factors to formulate appropriate strategies for their conservation and rehabilitation.
