In a series of prey- choice experiments, 3 gastropod and 4 crustacean predators were each offered 3 Tridacna spp. and Hippopus hippopus. In a second series, T. gigas and H. hippopus were each offered to the gastropod ...

It has been predicted that the global demand for fish for human consumption will increase by more than 50% over the next 15 years. The FAO has projected that the increase in supply will originate primarily from marine ...

The growth performance of three experimental groups consisting of mixed sex fish (control), hormone-treated fish and progeny of YY male tilapia, all originated from the genetically improved farmed tilapia (GIFT) strain was ...

Barbus paludinosus and Barbus trimaculatus were sampled in Lake Chilwa and the Mnembo River mouth between February 2004 and January 2005, using nets equivalent to those used commercially, to analyse their reproductive ...

Catch rates for both Nile perch (Lates niloticus) and dagaa (Rastrineobola argentea) from Kenyan waters of Lake Victoria have steadily increased through the 1980s, even though the fishing effort also increased during the ...

Based on the encouraging results obtained by earlier workers, the concept for a floating hatchery was developed for producing tilapia for both farming and enhanced fisheries in the freshwater lakes and coastal lagoons of ...

Selection response for body weight at marketable size was measured for channel catfish, Ictalurus punctatus, grown in earthen ponds at 7500 fish/ha. Three generations of mass selection for increased body weight in Kansas ...

It is proposed that the "recruitment pattern" routine of the ELEFAN II program can be modified to allow, in addition to length-frequency data, the use of "restructured" data files. An example, based on Oreochromis niloticus ...

The present study aimed to investigate the effect of both garlic and yeast (Saccharomyces cervecesa) on survival and growth performance of cultured Nile tilapia (Oreochromus niloticus), besides studying its immune stimulatory ...

Rearing fish in seasonal floodplains raises productivity but can adversely affect the poor and the biodiversity of important natural fisheries. Equitable community institutions enable poor rural households to cooperate ...
