Pengaruh penambahan karbon aktif terhadap pertumbuhan dan kelangsungan hidup lele (Clarias gariepinus) dalam wadah terkontrol

This study aimed to determine the effect of addition of different activated carbon on growth of catfish, feeding efficiency, and feeding conversion ratio and survival rate. This research was carried out in the Aquaculture Technology laboratory, Faculty of Fisheries and Marine Science. The media test was an aquarium with the size of 60 x 40 x 40 cm placed in laboratory. The experimental design was a completely randomized design with 5 treatments and 3 repetitions. The charcoal used in this experiment was A: 1%, B: 2%, C: 3%, D: 4%, E: without charcoal. The observed variables were total growth, relative growth, daily growth, feeding efficiency, feed conversion ratio, and survival rate. The results of statistical analysis on growth parameters indicated the same effect on the growth of 4-6 cm catfish juvenile. The highest weight gain was achieved in treatment C (2,62±0,1), which was pellet feeding with a composition of 3% charcoal, as well as relative growth (413,47±36,3), and daily growth (1.3±0,2). The treatment showed significant effect on efficiency. The highest feed conversion ratio was in treatment E (2,06±1,4), which was pellet feeding with 0% charcoal, and the lowest in treatment C (0,76±0,1). This study concluded that addition of charcoal 1%, 2%, 3%, 4% and without charcoal had the same effect in triggering 4-6 cm catfish growth.Keywords: Active carbon, catfish, growth, feeding efficiency, feeding conversion

This study aimed to evaluate of patin seed (Pangasius hypothalamus) that is given Tubifex sp. as additional feed. The experiment design was used completely randomized design with four treatments and four replications. The treatments studied were 100 % pellet without the addition of Tubifex sp. (A), 95 % pellet with the addition of Tubifex sp. 5 % (B), 90 % pellet with the addition of Tubifex sp. 10 % (C) and 85 % pellet with the addition of Tubifex sp. 15 % (D). Patin seed stocking density was 1 individu/l with the length of 3-4 cm and weight of 0,15-0,28 g. The culture period for one cycle of fish farming was 40 days. The ANOVA test showed commercial feeding with the addition of Tubifex sp. as additional feed gave the significant effect on the specific of growth rate, length and feed conversion ratio, but did not give the significant effect on survival rate of patin seed. The best dose to increase the growth of catfish seeds is 85% commercial feeding with the addition of Tubifex sp. 15%.

Feed Costs

Feed is one of the production costs which accounts for 65% of the total production cost of sangkuriang catfish (Clarias sp.) cultivation, so there is a need for alternative feed ingredients that can reduce feed costs. The use of local raw materials in making feed can be an alternative in cultivation activities and is expected to reduce production costs. This study aims to determine the effect of feeding local raw materials with different proteins on the growth of catfish seeds and to analyze the cost of feed production. This research was conducted on March 20 to June 18 2020 at the Integrated Field Laboratory of the Faculty of Agriculture, University of Lampung. The research design used was a completely randomized design with 4 treatments and 3 replications, namely feed A (32%), feed B (30%), feed C (33%) and feed D (36). The data obtained were analyzed by using the ANOVA test and followed by the Duncan test. The parameters observed in this study were absolute weight growth, daily growth rate, feed conversion ratio, survival rate, protein retention, water feed resistance, feed cost analysis and water quality. The results showed that D feed with 36% protein treatment had a significant effect on the feed conversion ratio of sangkuriang catfish. Feed D resulted in the lowest FCR of 0.58.

Clarias gariepinus juveniles of average weight, 17.57±1.95 g and an average length of 14.26±0.39 cm were exposed to environmentally relevant concentrations of 0 (control), 2.5, 25, 250, and 500 µg L-1 atrazine in a quality-controlled 28-day bioassay. Growth performance was assessed bi-weekly and fish samples were taken from different tanks to determine the relative growth rate, specific growth rate, feed conversion ratio, condition factor and behaviour. At the end of two weeks of exposure, the relative growth rate and the specific growth rate among exposed fish groups was found to reduce significantly (p<0.05) compared to the control, an indication of poor growth performance. The average specific growth rates (SGR) of control fish is 3.86±0.02 %/w at the end of the exposure duration while recording -0.64±0.09 in the 500 µg L-1 group. Feed conversion ratio increased significantly from control to the group with highest atrazine concentration. Condition factor (K) of fish among treatment groups showed significant decrease in values with increasing concentration of atrazine in a dose-dependent pattern. Atrazine exposure resulted in behavioural anomalies including erratic swimming, clinging to the water surface, loss of equilibrium, lethargy, and discolouration. The behavioural responses were found to be concentration-dependent. The length-weight relationships for both control and atrazine exposed fish exhibited positive allometric growth and significant relationships as depicted by the value of R2 (coefficient of determination) except in the fish group exposed to 500 µg L-1 atrazine which exhibited negative allometric growth. Findings from this study indicate interference with normal behaviour and growth performance of C. gariepinus juveniles with ecological implications in water bodies exposed to atrazine even at reduced concentrations.

Barb (Barbonymus balleroides Val. 1842) is one of the native species found in many rivers of Asian countries, including Indonesia. This species had higher commercial value compared with other fish species popular among consumers. In terms of supporting its domestication, information regarding the optimal aquaculture system of the fish is needed, one of which is its rearing location. Currently, there is limited information on rearing the fish at different locations with different altitude. This research aimed to obtain the growth of barb fingerlings reared in three locations with different altitudes. The study was conducted in the ponds located at Cijengkol area (ASL<200 m), Maleber (200 m<ASL<400 m), and Ciherang (ASL>400 m), West Java. Fingerlings of domesticated barb (total length 4.48 ± 0.10 cm; weight 0.95 ± 0.06 g) were stocked in three fixed net cages (size 2 m × 2 m × 1 m) in a pond (40 m × 20 m) at each location. Fish were fed with commercial feed (30% protein) of 5% biomass three times per day during 120 days of rearing. Water quality parameters observed were temperature, dissolved oxygen, and pH. Measured parameters were length gain, weight gain, specific growth rate, average daily growth, biomass gain, feed conversion ratio, and survival rate. The results showed that the fish reared in Maleber showed the best growth and feed conversion ratio compared to other locations (P<0.05). Meanwhile, no significant differences were found on the survival rate within all treatments. The growth of barb fingerlings is more optimal if reared in midland areas which have suitable temperature ranges for their growth.
