To investigate the potential of extensive net cage culture for Nile tilapia (Oreochromis niloticus) fingerlings, an experiment was conducted in net cages suspended in a fertilized pond. Mixed-sex population of Nile tilapia with an average initial body weight of 0.065 g was used to stock in experimental cages. Four treatments; non added-substrate without supplemental feeding (NSNF), non added-substrate with supplemental feeding (NSAF), added-substrate without supplemental feeding (ASNF), and added-substrate with supplemental feeding (ASAF) were tested. The results indicated that addition of substrates which gave an additional submerged surface area of approximately equal to the total cage surface area did not show significant effect on the growth (p > 0.05). The fish gross yield obtained from non added-substrate cages without supplemental feeding was 1.22 kg/m3 for a 56-day period.DOI: http://dx.doi.org/10.3126/on.v10i1.7752

This research was conducted in May-June 2017 in Hatchery Indoor Maksudi, Astanaanyar, Bandung. This research aims to find out the optimal BIOM-S probiotic on culture media of Nile tilapia, and the influence to survival rate and growth rate of Nile tilapia. This research was conducted by an experiment using Completely Randomized Design (CRD). This research consisted of five treatments and three replications, which were treatment A (control), treatment B (giving probiotic with 0,6 ml/L concentration), treatment C (giving probiotic with 0,8 ml/L concentration), treatment D (giving probiotic with ,0 ml/L concentration), and treatment E (giving probiotic with 1,2 ml/L concentration). The parameters in this research were the survival rate and specific growth rate. Survival rate and specific growth rate used data analysis with F test to find out the influence of each treatment. The concentration of optimal probiotic based on the results was 0.8 ml/L, it produced the highest survival rate for 81.67% and the specific growth rate for 0.039%.

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.

Significant Difference

Fish meal is generally expended as the foremost protein supply in the fish diet. The rising cost of this component inflicted the aquaculture industry to seek a substitute in lessening the pellet cost. Thus, fish waste was tested in this study to investigate its viability. An experiment was performed to study the effects of fish waste and carcass on the growth performance of Nile tilapia fry. Solid fish waste of three different common species available in Mukah’s wet market was formulated into an artificial diet. The diet was formulated into three treatments consist of three protein levels (40%, 45% and 50%) with 4000 kcal/kg energy. A controlled group was fed with a commercial pellet consisting of 45% protein level. Fish were fed at 4% of body weight twice daily for 45 days. Fry reared in a controlled group was discovered highest weight gain, specific growth rate and length gain. There was no significant difference in all treatments for all parameters measured. The lowest weight gain and specific growth rate were recorded in fish fed 45% protein level (T2) group. Fish in T3 (50%) achieved the highest survival rate while T1 (40%) group recorded the lowest. The best and lowest Feed Conversion ratio (FCR) was recorded in the control group. In conclusion, the performance of formulated feed using fish waste is similar to commercial pellet as no significant difference can be observed in all parameters measured.

Water Ph

The present work aimed at reassessing the suitable range of water pH for culture of Nile tilapia, Oreochromis niloticus L. juveniles in eutrophic water. Two hundred and forty tilapia juveniles (1.37 ± 0.04 g) were stocked in twenty 250-L polyethylene tanks (12 fish per tank) for eight weeks. In the control tanks, the pH of water was not adjusted at any time, varying freely over the entire study. In the slight acidification treatment, the culture water was acidified daily to reach a water pH between 5.5 and 6.5. In the moderate acidification treatment, there were daily applications of HCl solution to reach a water pH between 4.5 and 5.5. In the alkalinization treatment, tanks received daily applications of Na2CO3 and NaOH to achieve a water pH between 8.5 and 9.5. Acidification of water, regardless the degree, i.e., slight or moderate, was not able to significantly affect final body weight, specific growth rate and yield of fish. It can be concluded that the acidification of water up to pH 5.5 has no negative influence on growth of Nile tilapia fingerlings in eutrophic tanks. Accordingly, the suitable range of water pH for rearing Nile tilapia should be set at 5.5 – 9.0.
