CONSERVATION OF FISHERY RESOURCES:
The
potential of fishery resources in the state are immense. The major potential resource
attributes to the cold and riverine fisheries. It comprises of game fishes like mahseer,
also known as the ‘National fish of India’
and snow trout. Ornamental fish species such as loaches, danio, barillius etc., are also
added assets. But unfortunately, this fishery resource of the state is threatened due to
indiscriminate and destructive fishing methods like poisoning, dynamiting, bleaching,
electric fishing, and use of unregulated mesh size net. This destructive fishing method
indiscriminately kills the juveniles and the brooders leading to decline in riverine fish
species. Hence serious efforts from all corners should be made to conserve our riverine
fishery resources. The following approaches for conservation of aquatic flora and flora
and their ecosystem, are therefore considered.
- Deforestation
and overgrazing activities along the sloppy catchments need to be checked immediately.
- Soil
and water conservation measures need to be intensified.
- Enforcement
of fishery legislation (Indian Fishery Act/Nagaland Fisheries Act) in streams, rivers and
lakes to be effectively implemented.
- Specific
gear and mesh size need to be regulated to protect the juveniles.
- Observation
of closed season during breeding seasons.
- Declaration
of breeding and feeding grounds of fishes as reserves/sanctuaries.
- Banning
the use of poison, bleaching powder, dynamite and electric for fishing.
- Seed
ranching and their protection may be maintained for the declining stocks.
- Mass
awareness through extension activities and voluntary agencies about the need for
conservation of fish stocks and their ecosystem.
