  23. 23.  Major and abundant fishery resource among the marine pelagic fin fishes of the Indian seas. Distribution in the Atlantic and Indo-Pacific regions and in India they are distributed all along the coast with abundance in the northwest and central east coasts. In India T. lepturus found both east & west coast--- dominating species. Contributed about 92 -95%. Gujarat, Andhrapradesh, West-bengal, northern Maharastra, south-east cost of Tamilnadu, karnataka, Kerala etc are important landing centre.

  35. 35.  Basically ribbon fish is a by-catch species. So, it is come with other species…. Gear are used- Trawl net, Dol net, Gill net, Seine net, hook etc. are used throughout the India. In kerala mainly used- Trawl net, Gill net, Seine nets. By using trawl net ribbonfish landed 73- 74% . The gill net, purse seine and others contributed to 15- 16% during the decade 1991-2000. For catch juvenile trawl net, boat seine and ring seine net (mesh size less than 10mm) are used. Gear Amount(%) Year Trawl net 74 1991-2000 Drift Gill net, Boat 16 ,, seine, Shore seine, Purse seine and others
  36. 36. STATE-WISE DISTRIBUTION OF GEAR :- STATE GEAR Andhra Pradesh Trawl net, Gill net, Seine nets Orissa Trawl net, Gill net Karnataka Trawl net, Seine nets Goa Trawl net, Gill net Maharashtra Trawl net, Dol net Gujarat Dol net, Gill net West-bengal Bag net, Trawl net, Gill net
  37. 37. MANAGEMENT:- Ribbon fish is very important species as a by-catch, so for save this species many management options like effort regulation, closed season, closed area, gear regulation, mesh regulation. Intensive approach also seen for ensure good brood stock, for fishery industry.
  38. 38. OTHER FAcTOR:- It has low price in the market, so acceptable for poor people as a food- used as a cheap protein. Dried ribbon fish also use as fish product. Pearl essence formed from the guanine(present in the skin) Frozen & dried fish both are exported China, Japan and other southeast Asian countries.
