Evaluating Water Quality Parameters for Tank Aquaculture of Cat Fish in Cameroon

Eyongetta Stanley Njieassam

The water quality parameters were evaluated for feasibility of aquaculture in Catfish Clarias gariepinus for 56 days fishe of standard length 63.000 ± 2.361 mm were stocked in equal numbers in fifteen rectangular plastic tanks of size (0.32 m × 0.45 m × 0.24 m) in three replicates per treatment with water level maintained at 3/4 full. The water quality values were taken twice a week and recorded till the end of the experiment. The paired sample correlation was used to compare while the non-parametric tests were used to compare the significant differences for the four treatment groups. At the end of the 56 days study period, the non-parametric Spearman’s Rho test also gave a negative correlation between weights gained and dissolved oxygen values for all treatments and within weeks.
