Nile Tilapia Oreochromis Niloticus

The aim of this research was to determine the optimum percentage of glycerol addition into the diets of  Nile Tilapia (Oreochromis niloticus) on growth performance, feed convertion ratio, and survival rate. The research was conducted using 15 aquaria with the size of 60 x 50 x 45 cm3, each containing 25 O. niloticus with average initial weight of 4.63 ± 0.15 g. The experiment was conducted using a complete random design with five treatments and three replications. Isonitrogenous (31%) and isocaloric (17 MJ.kg-1) diets were provided for 60 days of rearing period. Five diets were formulated with glycerol content of 0% (G0); 5% (G5); 10% (G10); 15% (G15), and 20% (G20). Fish were fed twice daily with experimental diet at satiation level. The result showed that addition of 10% glycerol in the diet (G10) presented the highest values for weight gain (105.85 ± 0.40%), specific growth rate (3.44 ± 0.01%), protein retention (27.75 ± 0.02%), protein efficiency ratio (2.53 ± 0.15%), lipid retention (60.44 ± 0.03%), and feed convertion ratio (1.59 ± 0.01%) (P < 0.05). Survival rate was not affected by dietary containing glycerol (P > 0.05). Therefore, addition of 10% glycerol into the diet gave a significant increase on growth performance and feed convertion ratio without adverse effect on survival rate of Nile Tilapia.

Feed Conversion Rate

The performance of Nile tilapia (Oreochromis niloticus) raised in cages furnished with an automatic dispenser, supplied at different frequencies (once per hour and once every two hours) and periods (daytime, nighttime and both) was evaluated. Eighteen 1.0m³ cages were placed into a 2000m² pond, two meters deep with a 5% water exchange. One hundred and seventy tilapias, with initial weight of 16.0±4.9g, were dispersed into each 1m³ cage and the feed ration was adjusted every 21 days with biometry. Data was collected from March to July (autumn and winter). Significant difference to final weight (P<0.05) among treatments was observed. The increase in feeding frequency improves the productive performance of Nile tilapias in cages and permitted better management of the food. The better feed conversion rate for high feeding frequency (24 times day-1) can result in saving up to 360kg of food for each ton of fish produced, increasing the economic sustenance for tilapia culture and suggesting less environmental pollution.

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.

 This study was done to explore the effect of replacing mustard oilcake by linseed oilcake in feed on the growth performance of Nile Tilapia (Oreochromis niloticus). Mustard oilcake (MOC) was replaced by linseed oil cake (LOC) at three different level 0%, 50% and 100% to prepare three different types of diets. Diets were prepared with about 18% analyzed crude protein content. Fingerlings were kept in three happa with three replications for each diet in completely randomized design (CRD). Fish of average weight 5.31 g were stocked in happa having size 1.5m×1.5m×1.2m. The experimental fish were fed 3% of their body weight per day, once in the morning for five months continuously. No significant difference (p>0.05) in final mean weight, final total weight, average daily weight gain (DWG), survival rate, extrapolated gross fish yield (GFY), extrapolated net fish yield (NFY) and apparent feed conversion ratio (AFCR) among different treatments were observed. Hence, linseed oilcake can be used as the substitute in the feed of tilapia, if it is locally available.  Journal of Institute of Science and Technology, 2017, 22 (1): 10-16

AbstractThe aim of this research was to find out optimum percentage of given fermentation the prawn waste flour in artificial feed on growth of black nile tilapia. The treatment of this research was giving fermentation the prawn waste flour in artificial feed i.e. 0%, 2,5%, 5%, 7,5%, 10%. Each treatment was repeated 4 times. Feed compositon was made of isoprotein. Fishes weight were about 6.1 – 6.8 g. Fishes were cultured with stocking rate 3 fish per 20 liter water and the fishes were reared for 40 days. Feed amount that consumed by fishes was measured every day to calculate feed conversion ratio. The calculation of fishes amount was done in beginning and end of research to count survival rate of fishes. Water quality was measured on beginning, middle and end of research. The design of this research was Completely Randomized Design. Data analysis used Analysis of Variance (ANOVA) to know the effect of the treatment and that difference among the treatment used Duncan's Multiple Range Test (DMRT). The result of the research showed that the highest growrth rate were attained on feed containing 10% of fermented prawn waste flour. The best feed convertion ratio were attained on feed containing 10% of fermented prawn waste flour.

Abstract This study was conducted to determine an appropriate replacement of fishmeal with amino acids (AAs) and optimized protein levels in practical diets for Oreochromis niloticus with mean initial body weight 12.52±0.63g. Six experimental and a control diet (total 7 diets) divided into two groups, and a control diet (D1) containing 32% protein. The first group contained three diets that included different dietary protein levels, viz. 20 (D2), 25 (D3), and 30% (D4) with AAs when replacing fishmeal by plant protein sources. In the second group, the diets were contained 20 (D5), 25 (D6), and 30% (D7) without AAs. The best growth performance was achieved in fish fed with diet D1. Total feed intake was increased with an increase in dietary protein level with AAs. The specific growth rate showed a similar pattern with a significant difference between control, D4 and D7 compared to other groups. The feed conversion ratio decreased when protein levels in the diets increased. The protein efficiency ratio showed a similar performance, with a slight increase between the control diet and diets with AAs. However, insignificant differences (P>0.05) were observed between diets with and without AAs. An economic evaluation indicated that inclusion of low fishmeal in tilapia diets reduced the price/kg of diets compared to control.

Two experiments were conducted consecutively to evaluate and compare the mean weight (MWT), daily growth rate (DGR), feed conversion ratio (FCR), survival and production rate (PR) in the non-improved strain (NS) of the Nile tilapia, Oreochromis niloticus (Cichlidae) with those in the Genetically Improved Farmed Tilapia (GIFT) strain and the FaST selected tilapia (FaST), from the swim-up fry stage to fish weight of 1.0 g (Experiment 1) and from fish weight of 1.0 to 20 g (Experiment 2). In both experiments, results showed the GIFT and FaST strains to have significantly higher MWT, faster DGR, lower FCR and higher PR than those of the NS. Unlike in Experiment 1, survival rates did not differ significantly among the three strains. In Experiment 1, the improvements in the FaST for the MWT, DGR and PR over those for the NS were 77.9, 72.9 and 33.6%, respectively. In Experiment 2, the improvements for the same parameters were 58.7, 57.8 and 54.5%, respectively. These results indicate the advantage and potential of culturing the FaST or the GIFT strain in Kuwait for improving the production of fresh tilapia, reducing the production cost and increasing the profitability of tilapia farms.
