Recent Advances in Our Knowledge of the Biology and Conserv a Tjon of Mahseers

Mahseers, at one time considered to be of single species, are now represented by six valid species distributed all over India. Unfortunately, their catches have considerably dwindled due to illegal methods of fishing and habitat deterioration. Studies on their fciod habits, ecology of spawning grounds, eggs, larval development and especially methods of artificial propagation have fairly advanced in recent years. Transport of eggs of Tor khudree by air in moist cotton has been possible for easy distribution. Breeding of T. khudree not only by hypophysation, l:>ut even without it. in small ponds by manipulation of flow of water, exercise and feed has also been practicable. Fry and fingerlings of T. khudree is being distributed to many of the states in the country as a measure of rehabilitation and conservation
