Threats and Strategies for Conservation of Indigenous Fish Fauna of Paschim Medinipur: A Review
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 1
Abstract
Present work is a conceptual analysis and assessment of threats to indigenous fish fauna of Midnapur, West Bengal, India and suggestive remedies for protection of live gene bank of indigenous fish species. Development of standard protocol of induce breeding for small indigenous threatened fish species and its incorporation into the composite fish farming (community aquafarming system) will certainly be the sustainable conservation strategies to protect these threatened group of aquareseorces. 2. Biodiversity conservation in general and fish genetic resources in particular have become issues of great concern both globally and nationally. India is one of the 17 mega biodiversity hot spots contributing 60-70% of the world’s biological resources. In India, out of 765 native freshwater fish recorded by NBFGR, about 450 may be categorized as small indigenous freshwater fish species (SIFFS) which grow to the size of 25-30 cm in mature or adult stage of their lifecycle. Of the 450 SIF about 23% are highly important as food and local significance and play a significant role in the aquarium trade and in providing local livelihood security. Although rural population depend highly on indigenous species of fish for nutrition in many parts of India, very little attention has been paid on their role in aquaculture enhancement, nutrition, biology, captive propagation and biodiversity conservation research. They are quite invisible, absent from statistics and indigenous knowledge about the SIFFS and their benefits has been poorly documented. Consequently, many small indigenous fishes have become threatened and endangered due to pollution, over exploitation coupled with habitat destruction, water abstraction, siltation, channel fragmentation, diseases and introduction of exotic varieties. In order to achieve sustainable utilization, appropriate planning for conservation and management strategies are of utmost importance. The greatest challenge is to secure the IPRs related to SIFFS’ so that the country is able to maintain its stake on its indigenous resource and their potential benefits. Conservation of SIFFS is also essential to maintain ecological/nutritional and socio-economic equilibrium.
