The stability of a fishery system was investigated using two forms of a stochastic computer simulation model that was individually based in terms of the fishing boats. Fish catch was partitioned among boats according to two catch processes: an unranked process in which all boats had equal ability to catch fish and a ranked catch model in which a boat’s ability to catch fish depended on its weal...

compensatory growth response and body composition of male sailfin molly, poecilia latipinna subjected to short-term starvation and subsequent feeding were studied for 54 days. four feeding schedules were used in this study: c, control (were fed to apparent satiation throughout the experiment); t1, treatment 1 (3 days starvation and 6 days refeeding); t2, treatment 2 (6 days starvation and 12 da...

Knowledge of fish diversity, population data and the stock size, and calculation of the amount of proper catch are essential for a wise and sustainable management of lakes. This research reports a study on fish populations in Dorudzan reservoir, Fars Province. The fish were sampled from three stations in the late Summer and mid Spring 2015, three days each, using nylon gill nets. The mean lengt...

Globally, farmed seaweed production is expanding rapidly in shallow marine habitats. While seaweed farming provides vital income to millions of artisanal farmers, it can negatively impact shallow coral reef and seagrass habitats. However, seaweed farming may also potentially provide food subsidies for herbivorous reef fish such as the Siganidae, a valuable target family, resulting in increased ...
