Abstract

Aquaculture technology using Recirculating Aquaculture System (RAS) is basically a technology for fish farming by reusing water used in production. This technology is based on the use of mechanical and biological filters, and this method in principle can be used for all species cultivated in aquaculture such as fish, shrimp, shellfish and others. This study was carried out at Station for Investigation of Fish Health and Environment (LP2IL) Serang’s field test facility starting from June to November 2020 (110 days of sand lobster grow-out period). In this study, the RAS system used for grow-out of sand lobster uses a series of containers, compartments, tanks and equipment for water treatment with the following purification stages (1) sedimentation containers; (2) physical filtration; (3) biological filtration, (4) disinfection of water by UV irradiation, (5) removal of CO2, (6) clean water reservoirs and (7) tanks for grow-out of sand lobster. In this study, a series of tests were carried out on several biological activities parameters of sand lobster including growth weight and length, FCR, SR, molting and biomass, which were measured every two weeks during grow-out period. From the results of this study activity, it is found that the biological parameters of sand lobster grow-out with RAS is improving when compared to sand lobster grow-out in flow through water system (FT).

Abstract

Water quality is a limiting factor of life for aquatic biota, especially biota that lives in a pond. Therefore, water quality management is very necessary so that cultivation activities, especially ponds can continue and do not cause negative impacts on the surrounding environment. Various factors can decrease the water quality of aquaculture ponds one of which is from the remnants of feed and fish manure. Feed is one of the contributors to the dissolved organic matter in the cultivation pond. Maggot or black shoulder fly larvae are one of the alternatives that can be used as fish feed. Maggot has a high animal protein content of 30-45%, so it is very effective to be used as an alternative to additional feed in fish farming. The purpose of this research is to find out the difference in pond water quality between ponds by using maggot and pond feed by using pellet feed. The data taken in this study is primary data using the Complete Randomized Design (RAL) method with 3 treatments and 3 replays in each treatment. These treatments include Full Maggot Control (MU), 50% pellet, and 50% maggot (PU). Data obtained include; ammonia. Nitrites, and nitrates. The results showed that the average final value of ammonia, nitrite, and nitrates respectively treatment is KU ( 0.22 mg / L, 0.44 mg/L, 3.667 mg/L), PU (0.022 mg/L, 0.042 mg/L, 3.433 mg/L), MU (0.046 mg/L, 0.028 mg/L, 2.653 mg/L). The results illustrate the conclusion that the provision of maggots as an alternative and additional feed can improve the quality of aquaculture water.

Abstract

Feed is one of the most important aspects that cannot be left out in the fish farming process. One of the problems often faced by cultivators is the high price of feed due to the use of imported raw materials, such as soybean meal flour. To reduce the use of soybean meal flour, a new innovation was carried out in the form of substitution of local raw materials, namely Indigofera sp. This study aims to determine the effect of TDI (Indigofera sp.) as a substitute for soybean meal flour on growth performance on rearing red tilapia (Oreochromis sp.). This study used a completely randomized design with 4 treatments and 3 replications. P1 (without TDI usage), P2 (10% TDI usage), P3 (20% TDI usage), P4 (30% TDI usage). The data obtained were analyzed using analysis of variance (ANOVA) then further tested with Duncan's test. Based on statistical analysis, the test feed had a significant effect (p<0.1) on FCR was not significantly different (p>0.1) on the growth of absolute weight, absolute length, SGR, and SR of fish. The result of this study is that the use of TDI (Indigofera sp.) can be used up to a dose of 30% as a substitute for soybean meal flour in red tilapia feed, because it produces the same absolute weight growth, absolute length growth, SGR, and SR as the control feed.

Abstract

Length of time entering readiness early reproduction so that the relative fecundity and the low degree of fertilization and the degree of hatching in the goldfish hatchery are a challenge in the effort to provide goldfish seeds in quality and quantity. The effort was made by combining kroto and oocyte developer in the female goldfish. This experiment was carried out in September 2019-March 2020 at the Aquatic Productivity Laboratory of the Faculty of Agriculture, University of Lampung. The test fish used were 60 females 5-month-old brood stock, with an average weight of 14.69±3.69 g. This study used a completely randomized design using two factors, kroto (g / kg of fish) and oocyte developer (ml / kg of feed) with two levels each: K1O1 (0 + 0), K2O1 (30 + 0), K1O2 (0 + 0.5), and K2O2 (30 + 0.5) and 3 replications for each treatment. The results showed that factor K (kroto) and factor O (oocyte developer) had no effect on the relative fecundity of female goldfish during 8 weeks of maintenance. Meanwhile, the combination of kroto and oocyte developer affected the relative fecundity of the female goldfish at the 8th week of rearing, the degree of fertilization, and the degree of hatching

Abstract

One of major problem of siamse catfish (Pangasianodon hypophthalmus) culture is Edwardsiliosis bacterial disease of Edwardsiella ictaluri, causes economic losses because it causes high mortality and reduces the quality of fishery products. Currently, the use of antibiotics as an effort to control the disease has been prohibited due to the impact of residual hazards, resistance and decreased food safety value. Therefore we need an alternative solution that is effective, efficient and applicable through the vaccines application. The aim of this research was to analyze the effectiveness of the Whole cell Edwardsiella ictaluri vaccine with different doses and different application methods to protect Siamese catfish (Pangasianodon hypophthalmus) from Edwardsiellosis disease. The research was conducted using a completely randomized design (CRD) method consisting of 3 methods, namely oral vaccine, immersion vaccine, and injection vaccine. Each method consisted of 4 different dose treatments with 3 replications. The results showed that the vaccine application using different methods resulted in different survival rates, relative survival rates, specific growth rates and mean time to death. The oral vaccine method using each different dose resulted in the best survival rate, relative survival percentage, and mean time to death. The immersion vaccine method with a dose of 10.9 resulted in the highest specific growth rate.

Abstract

Based on data from KKP, Indonesia recorded the value of crab meat exports in2017 ranked 3rd largest after Tuna and shrimp, namely by value nearly $ 411 million. This makes the crab catching volume increased. But there is a quality crab that is not always in condition good because of the disease that often attacks crab. Disease caused by parasites that affect population reduction and decrease in body weight of the organism, this is what causes the occurrence of consumer rejection. Attacks from ectoparasites can cause harm organs in the host organism, among others, damage to the body surface and  the gills of the host. This study aims to find out identification, intensity and prevalence of ectoparasites found in crab in Margasari Village Waters, Labuhan Maringgai District, East Lampung Regency. This study includes taking 40 crab samples obtained from the catch of fishermen from two stations, Panceran and Gambas stations. The data of ectoparasite samples found from the examination results are then recorded and for ectoparasite attacks on crab can be analyzed by counting prevalence and intensity. Crab ectoparasites identified in the Margasari village, Labuhan Maringgai, East Lampung Regency, among others Octolasmis sp., Chelonibia sp., and Thompsonia sp. In this study Thompson sp. it is the highest intensity crab ectoparasite, amounting to 471 / individual while Chelonibia sp. the Panceran station has a moderate prevalence of 33%, and other ectoparasites have low prevalence throughout the station
