Abstract Fishing is one of the oldest human activities and it developed gradually, when our ancestors moved from the collection of plants and animals to hunting by using tools and weapons.
Freshwater fish diversity of Central India
The oldest fishing implements so far identified are harpoons, found in the territory of Congo, and dating about 90, years. Interestingly, these harpoons were found associated with the bones of a species of now extinct giant catfish.
For this, a comparison was made between a 15km stretch of a protected area Katerniaghat Wildlife Sanctuaryand fish diversity in india unprotected one 85km downstream. In each site some physicochemical conditions were obtained, and fish were fish diversity in india by normal gears and the diversity per site described.
These small hillstream fishes include a single genus, viz. Further, the fishes of the family Psilorhynchidae with the only genus Psilorhynchus are also endemic to the Indian region.
Biodiversity of freshwater fish of a protected river in India: comparison with unprotected habitat.
Other fishes endemic to India include the genus Olytra and the species Horaichthys setnai belonging to the families Olyridae and Horaichthyidae respectively. The latter occur from the Gulf fish diversity in india Kutch to Trivandrum coast.
The endemic fish families form 2. Out of the species so far listed, 73 3.
Adequate protection of ecosystems is a necessary requirement for survival of all species and proper care is needed to overcome anthropogenic fish diversity in india. In the case of commercial species, rational exploitation is a pre- requisite for sustainability of the resources.
Overview of the Fish Diversity of Indian Waters - CMFRI Repository
There are about families of freshwater fishes globally. It not only kills other fish diversity in india but there are reports of it attacking humans too.
Its eggs are poisonous as well. It has no natural enemies and hence can become invasive in no time, destroying the local ecosystem and biodiversity. Not just Kolkata, the alligator gar has already spread to other states such as Telangana and Andhra Pradesh and reports of the fish becoming invasive in water bodies of Tamil Fish diversity in india are also coming in.
So how did this fish end up in our river waters when it is not from here?
Experts say they are usually smuggled into the country to be reared in aquariums. But when the fish starts gaining size and kills other fish, owners often release them in local water bodies.
