“…Previous studies have shown that feeding is one of the main factors required for faster growth and higher yield of cultured O. niloticus (Abdel-Tawwab et al 2007, 2010; Limbu and Jumanne 2014). When cultured in semi-intensive earthen ponds, O. niloticus has been shown to thrive on supplementary diets made from agro-byproducts augmented with fertilization based on its omnivorous feeding behaviour (Charo-Karisa et al 2006; Abdel-Tawwab et al 2007).…”

Supplemental effects of mixed ingredients and rice bran on the growth performance, survival and yield of Nile tilapia, Oreochromis niloticus reared in fertilized earthen ponds

Unaffordability of commercial feeds to semi-intensive Nile tilapia, Oreochromis niloticus farmers has led to reliance on supplemental feeding and fertilization for nutrition of their fish without a scientific basis. This study compared the growth, survival, condition factor and yield performance of O.niloticus fed on mixed ingredients (MI) and rice bran alone (RB) diets reared in fertilized earthen ponds in small scale farmers’ ponds. The study also determined phytoplankton composition, biomass and abundance in the experimental ponds. Quadruplicate ponds were stocked with O. niloticus and African sharptooth catfish, Clarias gariepinus at a stocking ratio of 1:3. The initial mean weights of O. niloticus and C. gariepinus were 14.62 ± 0.61 and 20.34 ± 1.44 g respectively. The fish were fed on MI and RB diets with protein content of 184.74 and 126.06 g kg−1 respectively for 270 days. The results showed that growth performance, survival rate and condition factor of O.niloticus were not affected by either feeding with MI or RB diet (p > 0.05). Moreover, there were no significant differences obtained in phytoplankton biomass and abundance in O.niloticus ponds fed on the two diets (p > 0.05). Furthermore, feeding O.niloticus either on MI or RB diet did not affect the net and gross fish yields (p > 0.05). The study revealed that the use of either MI or RB diet does not significantly affect the performance of O.niloticus cultured in semi-intensive earthen ponds where natural food organisms are an integral part of the culture system. Rice bran could be used for semi-intensive culture of O.niloticus in fertilized ponds to boost the production based on its availability and low cost.

“…There is, however, general agreement on the major beneficial effects of prebiotics (Scheppach et al, 2001). Diet supplementation is an important aspect in aquaculture management especially in intensive or in semi-intensive fish culture and is promising for increasing fish production (Liti et al, 2005 andAbdel-Tawwab et al, 2007).…”

A b s t r a c t A r t i c l e I n f oTow experiments were carried out on Nile tilapia (Oreochromis niloticus) fingerlings to evaluate the best stocking rate and the level of a dietary prebiotic, respectively to obtain good performance after 75 days of the rearing. The obtained results revealed that the lowest stocking rate (5 fish/m 3 ) and the highest level of the prebiotic (2 g/kg diet) reflected the best results in most studied measurements for the nutrients utilization, carcass physical and chemical quality, and blood.

A b s t r a c t A r t i c l e I n f oThe use of the microalgae Spirulina in aquaculture has several potential advantages over the production of fish. This study was designed to investigate the effect of different replacement levels of fishmeal with Spirulina on some microbiology counts of common carp Cyprinus carpio L., the trail was conducted for 105 days and for this purpose 200 fingerlings common carp had been used. Five experimental diets were used and Spirulina replaced fishmeal protein from the standard diet at0% (T1), 5% (T2), 10% (T3), 15% (T4) and 20% (T5) levels. Psychrophilic count, coliform and Escherichia coli in common carp muscle, intestine and water rearing had been examined in which no psychrophilic bacteria in carp muscles were found as compared to control that were contain 16×10 4 , and the count of coliform bacteria decreased as the ratio of Spirulina increased in the diets, the highest was in control 1.2×10 2 while the lowest was in T3 with 2×10. Different count of psychrophilic bacteria were in common carp intestine; the higher was in the control group with 600×10 4 , while the lowest count obtained in the T5 with 0×10 4 , the same trend had been shown in the coliform counts in fish intestine in which the highest was in T3 with 35×10 2 but the lowest was in T5 with 2×10. The control showed lowest results in psychrophilic count in rearing water with 2×10 and the highest were in other treatments, regarding coliform counts the lowest value had been shown in T2 and T3 (1.5×10 2 and 1.5×102 ) respectively and the highest was in T4 (4×10 2 ).
