Analysis of resource use efficiency among small-scale fish farms in Cross River State, Nigeria

The study used the stochastic production frontier model to analyze the resource use efficiency among small scale fish farms in Cross River State, Nigeria. The mean efficiency of 0.89 was obtained indicating room for farm efficiency improvement by 11%. Quantity of feed, farm size (pond size), labour and capital had significant influence on fish production in the study area, with positive coefficients of feed quantity and...

Dietary added bamboo charcoal can evoke Pangasianodon growth and can reduce ammonia from culture medium

Ninety-days feeding trial was conducted to determine the growth performances and reduction of ammonia by adding of dietary bamboo charcoal (BC) of pangasiid catfish, Pangasianodon hypophthalmus. Four levels of BC (0, 0.5, 1, and 2% treated as T0, T1, T2 and T3, respectively) were supplemented to the test diet composition. The growth performance and ammonia elimination were influenced by feed type. The mean value of...
