<p>This experiment was conducted to evaluatee the nutritional value of <em>Leucaena leucocephala</em> leaf meal (LLM) with supplementation of sheep rumen liquor crude enzyme on the growth of Nile tilapia. Fish were fed isonitrogenous (± 32% crude protein and C/P ± 9.25 ccal/kg) diets for 50 days.  Six diets were  formulated to contain hydrolyzed LLM at level 10%, 15%, 20%, 25% and 30% (Diet A, B, C, D and E respectively) and one diet acting as a control (Diet K, 0% LLM). All diets were isonitrogenous and isoenergy.  A seven week feeding trial was carried out on triplicate groups of eight fish (9.38  ± 0.41) in 18 aquarium with a recirculating system.  Fish were fed twice daily at satiation.  Results of the present study indicated that the fish fed diet contained 0%, 10% and 15% of lamtoro leaf meal had significantly higher in specific growth rate (SGR) than other groups (<em>p</em><0.05).  The amount of feed consumed was no significant different in all groups and have tendency decreasing the amount of feed consumed with the increasing of <em>Leucaena</em> leaf meal hydrolyzed content in the feed. Feed efficiency in treatment 10% LLM has significantly difference with treatment 0, 20, 25, 30% LLM.

An 8-week feeding trial was conducted to evaluate the effect of Moringa oleifera leaf meal (MOLM) on growth performance, antioxidant status and morphological indexes in Nile tilapia (Oreochromis niloticus). Resistance to Streptococcus agalactiae was also assessed based on a 192h challenge experiment after feeding trial. Fish (initial mean weight 4.05±0.05g) were held in 21 tanks (volume 300L, 30 fish/tank), with triplicate treatment groups being fed to apparent satiation three times each day on practical diets adding different levels of MOLM (0, 0.1, 0.5, 2, 5, 10 and 20%). Sampling procedure was performed after 24h of fasting. Growth metrics showed no significant differences among groups. Whole-body lipid content, viscerosomatic index and intraperitoneal fat ratio were decreased as dietary MOLM levels increasing. Total superoxide dismutase (T-SOD) and reduced glutathione content (GSH) were significantly influenced by MOLM. Moreover, the lowest cumulative mortality rate (CMR) after challenge experiment was noted in 10% group. Based on CMR and quadratic regression analysis of liver GSH content, it was concluded that dietary MOLM levels of 8.15-10.00% may be beneficial for enhancing resistance to S. agalactiae infection. Our results suggest that the maximum additive amount of MOLM reached 20% under the condition of the present study.

Pigeon pea (Cajanus cajan) meal was substituted for soybean meal in the practical diets for Nile tilapia Oreochromis niloticus fingerlings. Six iso-nitrogenous diets (35% crude protein) were formulated in which heat-treated soybean meal was replaced at varying levels (0, 20, 40, 60, 80 and 100%) with protein from pressure-cooked and sun dried pigeon meal (23% crude protein). Nile tilapia fed 60% pigeon pea meal had significantly (P<0.01) better growth response and nutrient utilisation. Growth was depressed in low pigeon pea fish and also in high (above 60%) pigeon pea diets. The poorest feed conversion ratio was observed from 100% pigeon pea fed fish.

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.

Production feasibility of monosex nile tilapia, Oreochromis niloticus was studied in eight brackish water ponds, where tilapia fries with the average body weight (ABW) of 0.15 g were stocked at a density of 5/m2. Salinity of the ponds varied from 11 ppt to 14 ppt. Fishes was fed with floating feed containing 35% crude protein. After 105 days of culture, production of tilapia was 6334.20- 8099.50 kg/ha with an average mean of 7456.35 ± 589.60 kg/ha. This production was achieved when average body weight and survival of tilapia was 176.50 ± 18.44 g and 84.42 ± 7.23%, respectively. This growth and production tilapia was higher and very much comparable to the production of tilapia reported from freshwater bodies. The study indicates that tilapia can be grown as crop diversification in brackishwater ponds, where stocking of shrimp now become risky due to invasion of diseasesBangladesh J.
