Abstract

Fishes have always been an important source of food for mankind. Naturally, man is much concerned with not only its exploitation but also its various research aspects such as taxonomy, biology, fishery, aquaculture and even genetics. Taxonomically, the unit of fishery resources is the species, a concept developed during the classical periods of Linnaeus, Lamark and Darwin. The species concept still remains as the corner stone of scientific research in various aspects of biology. Nevertheless, according to the Darwin's theory of origin of species and modern theories of evolution, the species cannot remain as a constant entity. Each species may undergo further evolutionary changes leading to further speciation. The process and order of such further speciation is primarily by reproductive isolation and transform ation of its populations into different races or sub-species and la ter into new species in an unspecified evolutionary time scale.
