During the year 1995 – 2003 the higher catches were recorded from 1997 – 2000 with highest of 474456 metric tons in 1999 (Anon, 2006 b). Further separation of the data between cartilaginous and bony fishes indicates higher catch of sharks and rays than that of bony fishes.
Detailed Ecological Assessment Report 2008 – Keti Bunder Elasmobranches are quite diverse and abundant there are number of pelagic and demersal species that often are caught and sometime form abundant part of the commercial catches. Saw sharks (Pristophoridae) are rare and often caught in deeper parts of Arabian Sea. Hammer headed sharks ( Sphyrna sp ) once very common are rare in catches. Saw-fish (Pristidae) are seen in trawl catches. Several species of Rajidae occur through out the Arabian Sea, Rhinobatidae, Torpedinae, Rajinae and Dasyatinae commonly occur in estuaries and shallow open seas. There is no specific fishery but these species are often caught in trawl net and because of low fecundity are especially sensitive to fishing pressure (Anon, 2006 b). Since the study of Qureshi, 1972 no other studies have appeared in the literature. There are some published lists of Elasmobranches species given as check list of Marine fishes of West Pakistan (Jaleel and Khalil Uddin, 1972). Dominant pelagic communities are the fishes of Clupeiformes. These are not only in pelagic ecosystem but also in the benthic-demersal ecosystem. Several species dominant in occurrence in the region belong to genera Ilisha, Pellona, Pellonula, Opisthonema, Opisthopterus and Sardinella (Qureshi, 1955). All Clupeiformes fishes are separated as Clupeoides, Shads, Sardinella Thryssa, Chirocentrus and Megalops. The abundant species is Sardinella longiceps its catches have declined from 45 thousand metric tons in 1995 to 21,000 metric tons in 2003. The other abundant species is Thryssa sp its catches were 17,000 metric tons in 1995 and have declined to 10,000 metric tons. Other species caught show low catches but the decline in their catches from 1995 to 2003 is very distinct (Anon, 2006 b). Mostly these species constitute major part of trash fisheries that is used for poultry feed or in fertilizers industry. Among the marine catfishes Ariidae, Tachysuridae occur inshore and in estuarine areas. Arius, Bagre and Trachysurus dominate this group (Qureshi, 1955). Some larges Size of catfish Ariidae were observed during November surveys in catch from Keti Bunder. Among the fishes of Scorpaeniformes Trigla, Lepidotrigla, Prionotus and Platycephalus are found abundant in the coastal areas, estuaries and along the continental shelf.. (Qureshi, 1955; 1970). Three families Synodontidae, Harpodontidae and Chlorophthalmidae of Myctophiformes are abundant along the continental shelf areas (Qureshi, 1955; 1970). Perciformes is the largest group of fishes that dominate the demersal fish fauna of coast, estuaries, mangrove swamps and continental shelf of the tropical sea. Along the coast of Pakistan three groups of the Perciformes can be separated into species associated with inshore muddy areas, of sandy bottoms like that of continental shelf and those that inhabit rocky areas. Drums and croakers (Sciaenids, Pseudotolithus) dominate demersal fish fauna. On muddy grounds and in the creeks (Hussain, 1973). In associations with Sciaenids are the threadfin fishes Polynemidae, Mugillidae and Ehippidae (Spade fishes) (Qureshi, 1960a. and b. 1969; Husain, 1973). Wide variety of Perciform families occur on sandy grounds are Sparidae, Nemptridae, Poasyidae, Mullidae, Gerridae and Leiognathids. Epinephelus, Serranus, Lutjanus, Lethrinus etc are the dwellers of rocky grounds in estuaries and offshore waters (Hussain, 1973). Generally Groupers and snappers dominate in trawl catches and long line fishing operations (Qureshi, 1955; Hassan, and Qureshi, 1969). The other important commercial group of fishes belongs to Perciformes which is represented by more than 100 species in catches.
