Molluscan fishery input and output data, 1999-2009, from Pakistani marine waters was analyzed by using two specialized software, CEDA and ASPIC, used in fisheries management. The highest and the lowest molluscan catch values were observed in 1999 (10208 t) and 2006 (6162 t) respectively, with an average catch of 8109 t y-1. Among five surplus produ...

Males that present infrequently in parthenogenetic Artemia are commonly called “rare males”. By rearing cloned parthenogenetic Artemia in the laboratory, the frequency of rare males was observed for seven Artemia populations with different ploidy compositions. The results showed that the values of the male:female ratio varied from 0.53:1000 to 1.40...

Four demersal trawl surveys were carried out in Pakistani marine waters in 2009-2010. Length frequency data of 3219 individuals were used to estimate growth, mortality and exploitation, whereas data of 671 individuals were used to estimate length weight relationship in Otolithes cuvieri (Trewavas, 1974). Length ranges from 3 - 35cm and weight range...
