Abstract
Stingrays belonging to Family Dasyatidae are commercially exploited in Pakistan (Northern Arabian Sea) since long and mainly landed as bycatch of trawling and bottom-set gillnet fishing, In some areas along Sindh and Balochistan coast target stingrays fisheries based on fixed gillnet used to main source of their landings. It is estimated that their commercial landings ranged between 42,000 m. tons in 1979 to 7,737 metric tons in 2019. Analysis of the landing data from Karachi Fish Harbour (the largest fish landing center in Pakistan) revealed that 27 species of stingrays belonging to 14 genera are regularly landed (January 2019-December 2019). Smooth coloured stingrays (Himantura randalli/M. arabica/M.bineeshi) contributed about 66.94 % in total annual landings of stingrays followed by cowtail and broadtail stingrays (Pastinachus sephen and P. ater) which contributed 24.42 %. Spotted/ocellated/reticulated stingrays (Himantura leoparda, H. tutul, H. uarnak and H. undulata) contributed and 5.71 % in total annual landings of stingrays. Scaly whipray (Brevitrygon walga) and aharpnose stingray (Maculabatis gerrardi) contributed about 1.95 % and 0.98 % in total annual stingray landings of stingrays, respectively. Three species leopard whipray (Hiamntura undulata), round whipray (Maculabatis pastinacoides) and Indian sharpnose stingray (Telatrygon crozieri) are reported for the first time from Pakistan coast. There is an important aimed fisheries for stingrays based in some coastal villages along Balochistan coast where fixed bottom set gillnet placed in shallow waters (15-20 m.), however, these fishes are also caught as by-catch of gillnetting and shrimp trawling. The paper discusses about commercial landings and conservation aspects of stingrays in Pakistan. It urges for enactment of national and provincial legislation for protection of stingrays as well as for placing some of the species which are either critically endangered, vulnerable or near threatened to be placed CITES appendices. It also urges for evaluation of a large number stingrays which have not been assessed for their IUCN Red List listings
