چکیده

This paper presents an experiment in which two different fish culture system types were evaluated for the short-term commercial of fingerlings Clarias gariepinus maintained at half recommended stocking rate; 82.5/m3 2 m3 water volume indoor blue fiber-glass tanks (IFT) and outdoor black plastic (OPT). The research objectives to assess suitability viability tanks. Initial mean body weight graded C. IFT OPT 11.32±2.25 g 10.92±2.44 (mean±standard deviation) respectively. study lasted eight weeks with attaining post-juvenile sizes 174.95±74.30 178.84±52.04 respectively not significantly p > 0.05. Survival termination was 81.21±0.0% 81.21±2.5% As attained larger 100 above between 6 8, skin lesions frayed fins observed comparatively more reared than fish. It may be concluded that systems are vastly terms resultant survival growth performance African catfish, however, duration halved when maintaining reported rate order prevent distress as a fallout aggression they increase size.

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Bioassay using the water soluble fraction of a Nigerian light crude oil on Clarias gariepinus fingerlings.

A 96-hour bioassay was conducted using the water soluble fraction of a Nigerian light crude oil sample on Clarias gariepinus fingerlings. 0, 2.5, 5.0, 7.5 and 10 mls of water soluble fractions (WSF) of the oil were added to 1000 litres of de-chlorinated tap water to form 0, 25, 50 , 75 and 100 parts per million representing treatments 1 to 5 respectively. Each treatment had two replicates with ...
