Toxicity of Copper (11) Tetraoxo Sulphate to African Catfish (Clarias Gariepinus) Fingerlings
This study was carried out to determine the toxicity of copper sulphate to African Catfish (Clarias gariepinus). The range – finding test was conducted twice in order to get reliable values that could be used for the definitive test. The toxicant (copper sulphate) was introduced at varying concentrations of 10g/l, 20g/l, 30g/l and 40g/l in the first rangefinding test, while it was introduced at...

متن کاملBioassay 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 ...
