Abstract

There are obstacles in the aquaculture business that is still often faced by farmers, one of the challenges is the high price of commercial feed. Feed as an energy source for growth is a reasonably high-cost component in production that reaches 40-89 %. In the control of food for efficiency, it could be done by the fasting method. This research was aimed to analyze the effect of periodic fasted of giant prawn (Macrobrachium rosenbergii de Man, 1879) against growth and feed efficiency. This research was conducted at IBAP Installation, Probolinggo District - East Java Province. The experimental method used completely randomized design with five treatments and three replications, such as; P0: feeding without fasting (as control), P1: a-day fasted, a-day feeding, P2: a-day fasted, two-days feeding, P3: a-day fasted, three-day feeding, P4: a-day fasted, four-days feeding, P5: a-day fasted, five-day feeding. The results showed that periodic fasted of M. rosenbergii no significant effect on the daily growth rate, absolute weight growth, and feed efficiency. However, by looking at the rate of growth, this fasting method could be used as an alternative to saving feed. The P5 showed the most effective in increasing daily growth rate, absolute weight growth, and effectiveness of giant prawn feeding. The strategy of periodic fasted to increase the production of giant prawns should consider the other supporting factors such as ideal water quality (pH, temperature, and DO), proper stocking density, and feeding periods on schedule.

Abstract

One of the freshwater fishes that began to be developed is Wader fish, but there is still a lot of information that has not been supported on fish farming techniques. One of them is the optimal stocking density for cultivation. The purpose of this study was to study the effects of different stocking densities on the growth and survival rates of the Wader Cakul fish (Puntius binotatus). This research was conducted in May - July 2018. The method used in this study was to use a Completely Randomized Design with 4 training, namely P1 (2 fish/liter), P2 (3 fish/liter), P3 (4 fish/liter) and P4 (5 fish/liter). Each treatment was repeated 3 times. The main parameters were absolute growth rate (length and weight gain)(GR), specific growth rate (SGR), survival rate (SR), and feed conversion ratio (FCR). Data were analyzed using ANOVA (analysis of variance) and continued with the Least Significant Difference Test. The results showed that different stocking densities gave significant values (P <0.05) for GR, SGR, SR and FCR comparisons. The best treatment in this study was P1 with a growth value of 0.31 ± 0.01 gram, SGR 3.50 ± 0.03%, Long Growth 1.97 ± 0.05 cm, SR 85.07 ± 2.17% and FCR 1.47 ± 0.02. P1 (2 fish/liter) is the best maintenance to increase the growth, survival rate, and feed efficiency of the cakul wader fish.Keywords: Wader cakul, Puntius binotatus, Growth rate, Survival rate, Feed Conversion Ratio

Abstract

Perkasa pangasiid (Pangasianodon hypophthalmus) is a superior catfish selected by the family that has been released by the Minister of Marine and Fisheries as aquaculture fish which has a selection response of 38.86 %. Genetic quality improvement to accelerate growth can be done through selection activities. The performance test of the Siamese catfish from the selection (Perkasa strain) compared to the non-selection strain (local strain) originating from the farmer. The purpose of this study was to compare the productivity of selection and non-selection Siamese catfish cultivation maintained in a net pond. The initial seeds of the test fish were 3.76 g to 3.79 g with a total length of 2 inches to 3 inches kept in a net pond measuring 3 × 5 × 1.25 m. The water level was around 100 cm with a density of 175 fish/net. Maintenance was carried out for six months. Test parameters observed included: weight gain, specific growth rate, biomass harvest, productivity and cost of production. The results showed that Siamese catfish which were selected for six months of maintenance had a final weight of 698.40 ± 164.54 g and non-selection strains of 595.77 ± 103.41 g. As well as having a higher specific growth rate (3.51 %), higher harvest biomass (11.44 %), and higher productivity (18.71 %) than non-selection Siamese catfish. Based on the bioeconomic analysis, the selection of enlarged Siamese catfish cultivation can reduce production costs up to Rp 390 /kg. The use of Perkasa Pangasiid superior seeds can increase harvest biomass higher than the non-selection seeds.
