翻译这段In India there are two species of anabas available i.e .A.testudineus and A.oligolepis.The fish having less deep body,lower pectoral and shorter snout is A.oligolepis with 46 chromosomes numbers and the fish with more deep body,shorter pectorals andlonger snout is A.testudineus with48 chromosomes numbers.Now anabas is a threatened species due to over exploitation and conservation measure is very much needed.Induce mass breeding and culture of this species may be ensuring to sum the fish in nature.This fish has a tendency to walk away from the pond during rains.Above all,the main constraints of culture of thisfish are non availability of seed from natural resources as well as artificial propagation.So it is essential to develop some of the standard breeding methods to overcome the cultural constraints
