Nile Tilapia Oreochromis Niloticus

The effect of substituting fishmeal with crustacean (Callianassa) meal in the diets of mixed sex Nile tilapia (Oreochromis niloticus) fry (0.2 g) was evaluated. Three isonitrogenous and isolipidic diets were formulated to contain 30% CP and 15% CL where fishmeal was substituted with Callianassa meal at 0, 25 and 50% in diets R1, R2 and R3 respectively. The experiment lasted for 6 weeks. The stocking density was 10 fish per tank in an isolated system and the capacity of each tank was 50L. Each treatment was administered in duplicates and fish were fed three times per day (09h, 13h, and 17h). The daily ration corresponds to 10% of the live weight of the fish during the first 2 weeks and was reduced to 8% and then 6% for the second and last two weeks of the trial period. At the end of the experiment, fish fed on R1 (control) diet and R2 diet (25% fishmeal replacement) had similar final weight (0.62 g), absolute mean weight gain (0.42 g), relative mean weight gain (210 %) and specific growth rate (2.50 %) and were significantly different from the values obtained from those fed on R3 diet (50% fishmeal replacement). R3 diet had the best FCR (1.42) and was significantly different from the values obtained from R1 and R2 diets but the values of the diets were not significantly different. The dry matter content of the initial fish (96.33%) and those of the R1 (94.12%) and R2 (95.71%) diets did not differ significantly but were slightly higher than that of the value obtained from fish fed on R3 diet (91.15). The protein content of the initial fish (49.63%) was significantly lower than the values obtained from fish fed on R3 diet (61.95%), R1 diet (54.74%) and R2 diet (52.59%). The fat content of the initial fish (41.51%) was higher than the values obtained when fish were fed on the experimental diets. Among the tested diets, the higher the crustacean meal in the diet, the lower the fat content of the fish muscle. The fat content of R1 (control) diet (29.56%) was slightly higher than the value of R3 diet (24.44%) and slightly lower than R2 diet (32.56%). It is concluded that crustacean meal can replace 25% of fishmeal in the diet of Nile tilapia (Oreochromis niloticus) fry at 0.2 g without any effect on the growth performances and feed efficiency.

Although fumonisins are identified as responsible for alterations in weight gain, little information is available on their effects on expression of growth-related genes, especially for Nile tilapia (Oreochromis niloticus) fingerlings. In this study, Nile tilapia fingerlings were treated with increasing levels of fumonisin B1 (FB1) and fumonisin B2 (FB2) (diets of 0, 20, 40, and 60 mg/kg) to evaluate their effects on weight gain (WG), feed intake (FI), feed efficiency (FE), growth hormone receptor (GHR) and insulin growth factor 1 (IGF-1) mRNA expression in liver of this fish. All variables were evaluated at 15 and 30 days of treatment. Diet containing 0 mg fumonisin/kg was used as control treatment. Treatment with 20, 40, and 60 mg fumonisin/kg of diet significantly reduced WG (P<0.0001) and FE (P<0.0001), while GHR and IGF-1 mRNA expression was reduced both at 15 and 30 days of treatment. Feed intake was not affected by diets in any of the evaluated periods. These results indicate that fumonisins (FB1 + FB2) affect the growth of Nile tilapia fingerlings through mechanisms that involve reduction of GHR and IGF-1 expression.

Swar NMS, Mohamed AHW. 2018. Incorporation of dietary palm date seeds in all-male Nile tilapia (Oreochromis niloticus) diets. Nusantara Bioscience 10: 193-202. The study utilizes a 45-days randomized factorial design 3×2, three levels (25, 50 and 75%) of palm date seeds, three levels (non, with and without) of 3% bakery yeast (Saccharomyces cerevisiae) and three replicates. The observation was carried out in twenty-one plastic aquaria. All-male Nile tilapia (Oreochromis niloticus) fingerlings were put in each aquarium. Each aquarium was provided with well-aerated and triggered dechlorinated tap water with an average weight of 1.9±1.11 g/fish (10 fish/aquaria) and a total length of 5.18±0.69 cm/fish. Fish were given food three times/day (10 days, at 8.30,11.30, 3.30 A.M) at a rate of 12, 8 and 4% of body weight, to examine the impact of partial substitution of animal protein (fish meal) in the diet on growth achievement, carcass contexture, feed utilization, condition factor (k) and feed expense. Seven experimental diets were prepared; control diet (T0, CP 36.84) concluding 45% (fish meal) as animal protein and 0% (palm date seed meal) plant protein. Tested diets (T1, T2 and T3) concluding 25, 50, 75% with 3% bakery yeast (CP 35.71, 35.53, 34.74) and 25, 50, 75% without yeast (CP36.01, 36.27 and 35.57) respectively ; so, they substitute about 75, 50, and 25 of fish meal diet respectively. The outcomes showed that, tilapia were given food on T1, T2 and T4 diets (25, 50, and 25%) substitution with and without yeast respectively registered the greater growth achievement, feed and protein utilization than other experimental diets such as control diet, also they indicate the highest condition factor (K) grades which state that the fish are in decent health. Tilapia were given food by diet T3 (25% fish meal) T5, T6 (50 and 25% fish meal) with and without yeast respectively possessed deficient growth and diverged remarkably (p>0.05) from the other diets. Diet contexture remarkably had an impact on carcass contexture. These data prompted that Palm date seed with and without yeast S. cerevisiae can, to a certain extent, substitute fish meal (animal protein) in a diet for all-male Nile tilapia fingerlings at level-up to 50 and 25% with and without yeast respectively, without any unfavorable result on accretion achievement. Furthermore, fish diet, partially substituted with 3% yeast, resulted from superior accretion achievement than other diets within the present experimental circumstance. This study showed that there is an economic efficiency of confounding palm date seed (plant protein) as partial substitution of fish meal (animal protein) with and without yeast in all-male Nile tilapia, that it could decrease the expense of feeds.

The present study assessed the effects of incorporating sea clam (Senilia senilis)meat mealas a partial replacement for fishmeal on the growth performance, survival and whole-body composition of Nile Tilapia Oreochromis niloticus fry(0.2 g).Three iso-proteins (26%) and iso-caloric (11%) diets where fishmeal was substituted withclam meat meal at 0% diet A,10% diet B, and 15% diet C were prepared.The experiment was conductedfor 12 weeks. The stocking density was 15 fish per tank in an isolated system consisting of 9 plastic tanks of 80L each. Each treatment was administered in triplicates, and fish were fed three times per day (09 :00h, 13 :00h, and 17 :00h). The daily ration corresponded to 10% of the fishs live weight during the first month and was reduced to 8% and then 6% for the second and last month of the trial period.The results of this study showed that the incorporation of clam meat meal in the diet of Nile Tilapia fry has benefited growth in fish fed the tested diets. The best growth performance was obtained in the fish fed with diet B containing 10% clam meat meal: 10.57g for absolute mean weight gain 4.75% /d for SGR 0.82 for FCR 2.14 for PER, followed by diet A.Diet C has the lowest growth performance: 8.37g for weight gain,4.44%/d for SGR,0.99 for FCR, and 1.75 for PER. The best survival rate was obtained by diet C (93.33%), followed by diet B (80%), and the lowest by diet A (71.11%). The protein contents of the tested fish were moderately higher than that of the initial fish. No big difference was observed among the tested diets. The ash content is reduced sharply after two months feeding. The lipid content of the tested fish decreasedslightly in comparison to the initial fish. At the end of the study, fish fed with diet B showed the best growth performance among other diets. These results indicatethat clam meat meal can be included up to 15% in the tilapia diet without affecting the nutritional quality of the feed.

The nutritive potential of water melon (Citrullus lanatus) seed meal as dietary protein source in the diet of Nile tilapia (Oreochromis niloticus) using growth performance and nutrient utilization were evaluated in a 56 day feeding trial. One hundred and fifty tilapia fingerlings of average weight 6.12±0.05g were acclimatized for a week, weighed and allotted into five dietary treatments; containing 0, 15, 30, 45 and 60% Citrullus lanatus replacement levels with soybean meal respectively. The diets (35% crude protein and 10% lipid) were isonitrogenous and isolipidic. Each treatment was replicated three times with ten fish per replicate. Fish were fed 5% body weight on two equal proportions per day to determine weight gain, percentage weight gain, specific growth rate, food conversion ratio, protein efficiency ratio and net protein utilization. The result from the study indicated that there was no significant (p>0.05) differences in the FCR and PER between the fish fed control diets and the fish fed test diets.
