Clarias serniosus, a new walking catfish (Teleostei: Clariidae) from Laos.
Clarias serniosus, a new Southeast Asian walking-catfish species, is described from the Bolavens Plateau in southern Laos. The new species is a member of the C. batrachus species complex, and can be distinguished from congeners in the complex in having a combination of: occipital process length 15-17 % HL, head length 28.2-28.6% SL, head width 18.5-19.2% SL, head depth 13.0-13.7% SL, distance b...
متن کاملEffects of Feeding Frequency and Handling on Growth and Mortality of Cultured Walking Catfish Clarias fuscus
Two experiments were conducted to study the effects of feeding freqnency on growth, and of handling stress on growth and mortality, in intensive tank culture of the walking catfish Clunas fuscus. In the first experiment, fish were grown from an initial weight of 37 g for 34 d. A fixed ration of 3.0% body weight per day was divided into either 1, 2, or 3 feedings per day, and fish were either ha...
متن کاملResponses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density
In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...
