Abstract

One of Indonesian aquaculture superior commodities is vannamei shrimp. The problems faced by freshwater vannamei shrimp farmers is that the shrimp growth is not optimal at 0 ppt salinity. Regarding shrimp survival, the crucial minerals needed are calcium (Ca), potassium (K), and magnesium (Mg). Calcium is able to increase shrimp skin calcium levels and the length of molting cycle, as well as for the growth of shrimp biomass and an increase in dissolved calcium can lead to an increase in pH. This research utilized calcium hydroxide Ca(OH)2, and was conducted for 45 days. The results showed that the highest SR value at P2 was 73.33%. The highest specific weight growth value was found in P3 as much as 6.21%/ day, and the highest specific length rate was found in P3 as much as 2.66%/ day. The highest coefficient of variance in weight was found in P2 with 46.3%, and the highest coefficient of variation in length was found in P2 with 12.88%. The best FCR value was found in P3 with 0.48. Therefore, adding Ca (OH)2 could increase the growth of vannamei shrimp in freshwater.

Abstract

The aim of this research is to analyze the effect of giving tuna bone meal as a mineral source to vaname shrimp cultivated in freshwater media, at doses of 1%, 2%, 3% and 4%. Fish bones are a form of fish processing industry waste that contains the highest calcium among fish body parts, because the main components of fish bones are calcium, phosphorus and carbonate. The calcium content in tuna bone meal is higher than the calcium content in other fish bone meal, namely in catfish bone meal 13.48%, mandidihang fish bone meal 2.12%, catfish bone meal 30.95% and in fish bone meal tuna ranges from 23-39%. Based on research that has been carried out, the addition of tuna fish bone meal has a real influence on the growth of specific weight, absolute weight, specific length, absolute length but there is no significant difference to FCR. The best value was obtained in Treatment 5 with the addition of tuna bone meal at a dose of 4% ( 4 grams / 100gram feed). Specific weight values at P5 (2.85%), absolute weight (27.8), absolute length (6.00cm), specific length (3.46%)

Abstract

In the aquaculture industry, feed plays a vital role because more than 50% of the production cost is for feed procurement costs. The feed used must not only contain good nutritional content, but also be economically affordable. The better the quality of the feed, accompanied by the cheaper the feed, the success of fish production activities can be guaranteed. The purpose of this study was to increase the use of local fish meal as a substitute for commercial fish meal in tilapia feed formulations. This study used a completely randomized design (CRD) model consisting of four treatments and three replications. The treatment applied was feeding the fish with artificial feed made from a combination of local fish meal with commercial fish meal at different doses. The treatments in this study werea (commercial fish meal 30% + local fish meal 0%), B (commercial fish meal 20% + local fish meal 10%), C (commercial fish meal 10% + local fish meal 20%), and D (commercial fish meal 0% + local fish meal 30%). The results of the analysis of variance (ANOVA) test showed that the treatment had no significant effect on the value of survival rate (SR), but had a significant effect on the value of Specific Growth Rate (SGR), Feed Conversion Ration (FCR) and blood glucose levels (GD). The SR values of treatment A, B, C, and D were 96.7%, 96.7%, 96.7%, and 100%, respectively. The SGR values of treatment A, B, C, and D were 0.15% / day, 0.24% / day, 0.29% / day, 0.35% / day, respectively. The FCR values of treatment A, B, C, and D were 10.25, 7.47, 5.00, and 4.16, respectively. The GD values of treatments A, B, C, and D were 217.67 mg / dL, 160.33 mg / dL, 155.00 mg / dL, and 132.67 mg / dL, respectively. The water quality during the research was still classified in the optimum range of tilapia rearing water quality, namely temperature 29.0?31.9 oC, pH 7.0?8.2, DO 4.3?5.9 mg / L, and ammonia 0.0011-0.0293 mg / L.

Abstract

Litopenaeus vannamei is a high-economic fishery commodity that has euryhaline properties, which is tolerant of a wide range of salinity values ??(2 – 40 ppt). The euryhaline of vannamei shrimp are still not well optimized. The purpose of this study was to determine the appropriate dose of ketapang leaf addition to increase mineral solubility in freshwater vannamei shrimp culture medium. The results of this study are expected to be useful as information for vannamei shrimp cultivators in freshwater media about technology for meeting mineral levels in the media so as to maximize production value. This study used a completely randomized design (CRD) method which consisted of 4 treatments and 3 replications. The treatment applied was the addition of ketapang leaves with different doses to increase the solubility of calcium carbonate (CaCO3) in cultivation media, namely A. Ketapang leaves (DK) 0 ppt + CaCO3 50 ppm; B. DK 120 ppm + CaCO3 50 ppm; C. DK 240 ppm + CaCO3 50 ppm; D. DK 360 ppm + CaCO3 50 ppm. The results showed that the appropriate dose of ketapang leaves that could increase mineral solubility in freshwater vannamei shrimp culture media was 360 ppm (treatment D). At this dose, the value of the specific weight growth rate of vannamei shrimp can increase, which is 0.76%/day. Treatment A is a control treatment that gives the lowest value for the specific weight growth value, which is 0.40 %/day.
