Ph Range

pH is one of the important water quality parameters in aquaculture. This study aimed to observe the growth performance and survival rate of common carp (Cyprinus carpio) Rajadanu strain reared in culture media with different pH levels. Fish (length: 3.60 ± 0.18 cm; weight: 1.68 ± 0.18 g) were stocked in nine aquariums (40 cm x 40 cm x 30 cm) for 10 days with a stocking density of 25 fish per aquarium. The treatments used were (A) pH 4-5, (B) pH 5-6, and (C) pH 6-7, with three replications. A commercial feed containing 28% protein was given daily and as much as 3% of the total biomass. The observed data were analyzed using variance analysis (ANOVA), followed by Duncan test. The results showed that the pH treatments did not affect the growth (length and weight) and survival rate of common carp Rajadanu strain (P>0.05). The best growth was achieved by the fish group reared in water with a pH range of 6-7 (length = 0.38 cm; weight = 0.17 g). The highest survival was attained by the fish group reared in water with a pH range of 5-6 (90.66%).

Pellet Feed

This study was aim to determine the different pellet feed source on the growth and survival rate of Nile tilapia. The purpose of this research was to provide information of the best feed for the growth and survival rate of Nile tilapia.Completely Randomized Design, with 3 treatments ( treatment A: community-made pellet, treatment B: commercial pellet PF500; treatment C: commercial pellet 885) and 3 replicate was used for the research. Nile tilapia with 3-4 cm length placed in nine aquariums with stocking density 6 fishes/L. Feeding treatment given twice a day at level 3 %/ body weight.  The parameters observed include growth rates, survival, and feed conversion. Supporting data was observed for water quality. Observation was carried out for 30 days.The results showed that the average weight, in treatment A was 101,66 g, treatment B was 118.33 g, and treatment C was 128.33 g. The average yield of relative growth in treatment A was 111.44%, treatment B was 134.23%, and treatment C was 135.76%. Treatment C shows the highest value, then treatment B and treatment A. The average yield of feed conversion, treatment A was 1.11; treatment B 3.21; and treatment C was 3.37. Survival rate of all treatments was 100%.
