“…Among these pair groups like prawn, crab, tripods, featherback, eels shared more numbers of niche overlapping pair. The numbers of pair with respect to each groups were noted following the descending order such as prawn (13), crab (11), tripod (11), featherback (9), eel (10), snakehead(8), elopiformes (8), cichlid(8), croaker(5), cyprinid(5), cat sh(5), gerridae (4), belonid (4), thread n (3), perch(2), clupeoid (1), benthos (1). Among the 108 pairs, if we lter the pairs through their magnitude of overlapping then 89 pairs were showing above 20% overlapping, 58 pair with 30% overlapping, 38 pairs with 40% overlap, 29 pairs with 50% overlap, 17 pairs with 60% overlap, 8 pairs with 70% overlap and 1 pair with more than 80% overlapping.…”
