Abstract

This study was conducted in tidal lowland at Banyu Urip Village, Tanjung Lago District, Banyuasin Region, South Sumatera. Samples were collected two times. The water sample was collected during high tide in primary, secondary, and tertiary canals. The result showed the seasonal variation of physical and chemical water parameters such as temperature 27 – 30 ºC, pH 3 – 5, DO 3.7 – 4.5 mg/l, phosphate 0.01 – 0.02 mg/l, TSS 108 – 232 mg/l, and EC 11 – 107 µmhos/cm. This study also identified 10 classes and 10 genera of phytoplankton. It has potential as a natural food source. The result revealed that physical and chemical water quality parameters were still suitable for aquaculture based on Government regulation of Republic Indonesia number 82 year 2001 about water criteria class III for fisheries. Meanwhile, the great challenge of tidal lowland for fishery management is low pH. Therefore, pre-treatment to increase pH before fish rearing is required.

Abstract

Bumi Dipasena Sejahtera as part of Bumi Dipasena, which is managed by PT. Dipasena Citra Darmaja is the largest shrimp farming in Southeast Asia. Since operating in 1980, Bumi Dipasena has made production up to 200 tons/day. However, the current condition shows a decrease in total production to 30 – 40 tons/day from 16.000 operated ponds. Decreasing production is caused by declining water quality. This study aims to find out about nutrient loading and water suitability based on water quality criteria. Nutrient loading is determined from total production calculated from three different ponds. Suitability analysis was conducted by matching and scoring methods based on water quality measured at 7 sites in the inlet, outlet, and pond site. The result shows that nutrient loading has the highest value at the highest production. Water suitability analysis both of inlet and ponds include in suit marginal class (S3).

Abstract

Providing high-quality feed is one of the efforts to increase fish productivity and growth and reduce fish mortality. One of the additional alternative feed ingredients as a source of vegetable protein is dragon fruit peel which can be used as an additional ingredient in fish feed. The study of the chemical composition of feed with the addition of dragon fruit peel flour is essential information to determine the effect of addition and the benefits of by-products (waste) from food processing in aquaculture development. This study aims to evaluate the quality of the chemical composition of feed after being treated with the addition of dragon peel flour through proximate analysis. The test was carried out at the Agricultural Product Technology Laboratory of Lampung State Polytechnic, from June to August 2020. The test results showed that dragon fruit peel flour had a carbohydrate content of 50.74%, crude fiber 26.22%, ash 21.35%, protein 5.08%, and fat 4.80% (dry weight). The test results showed that the addition of dragon fruit peel flour increased the protein content in the feed, which increased with the increase in the added dragon fruit flour. The highest protein content in treatment was 1.5%, namely 37.79% (dry weight), and decreased in the addition of dragon fruit flour by 2.0%. The highest ash content in the addition of 2.0% was 11.32% (dry weight). The content of crude fiber, carbohydrates and fat has decreased with the increasing dose of dragon fruit flour. The addition of dragon fruit peel flour can increase the protein content in the feed to substitute in the manufacture of fish feed. This also increases the utilization of dragon fruit peel waste, especially in aquaculture, to reduce waste disposal into the environment.

Abstract

One of the problems in North African Catfish (Clarias gariepinus) breeding is the inability to spawn spontaneously due to a specific spawning season. This happens due to reproductive dysfunction resulting in a slow development of gonads in catfish broodstock. This research aimed to study the effect of injection of pituitary gland extract from Striped Catfish head waste on the spawning performance of North Africans Catfish. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments were A (pituitary gland 0 mg/kg broodstock), B (pituitary gland 200 mg/kg broodstock), C (pituitary gland 300 mg/kg broodstock), and D (pituitary gland 400 mg/kg broodstock). The spawning process was performed with a ratio of 1:1 between male and female broodstock. The pituitary gland was injected into the head of female catfish at 07:30 pm and at 04:00 am. The research parameters observed were relative fecundity, fertilization rate (FR), hatching rate (HR), and survival rate (SR). The results showed that injection of the pituitary gland from Striped Catfish head waste could increase spawning performance with relative fecundity reaching of 31,357±12,265 eggs/ kg of female broodstock, FR 65±4%, HR 74±14%, and SR 81±10%. Therefore, hypophysation by utilizing Striped Catfish head waste is effectively increases the spawning performance of North African Catfish (Clarias gariepinus) seen from the high values of relative fecundity, FR, HR, and SR of larvae in treatment B (200 mg/kg broodstock).

Abstract

Pacific white shrimp (Litopenaeus vannamei) is a widely cultivated type of shrimp with high economic value. One of the obstacles in pacific white shrimp cultivation is an infectious disease, especially Vibrio spp. This study aims to identify bacteria of biocontrol candidate against Vibrio spp. This research was conducted by the Laboratory of Fisheries and Marine, Faculty of Agriculture, University of Lampung and the laboratory of PT. Indolab Utama, West Jakarta, from September 2019 to January 2020. Bacteria of Biocontrol candidate were isolated from traditional shrimp pond water in Purworejo Village, Pasir Sakti District, East Lampung Regency. Water samples were taken from the inlet, plot, and outlet. The bacterial screening was carried out by testing the antagonism of bacterial isolates isolated from water samples with several Vibrio bacteria, namely V. harveyi, V. algynoliticus, and V. parahemolyticus on Sea Water Complete (SWC) medium. The bacterial isolates with the highest inhibitory activity were then identified morphologically, biochemically, and molecularly by 16s rRNA. The results showed that from those 10 isolates was found 1 bacterial isolate from water samples. Only one pond plot isolate (P1) was found that had inhibitory activity against V. harveyi and the size was 21 mm. The morphological test results showed the colonies were round, flat edges, convex elevation, cream colored, and included in the negative gram bacteria group. The results of biochemical tests showed that the bacteria were motile. Meanwhile, the molecular test results with 16s rRNA showed that the P1 bacteria were 99% similar to Aeromonas caviae isolates, which were found potential as biocontrol candidates because they can inhibit the growth of V. harveyi bacteria, which was characterized by the formation of a clear zone around the paper disk.

Abstract

Eel (Anguilla bicolor) is an Indonesian freshwater commodity that has high economic value but has slow growth. One method to accelerate eel growth is through feeding with the enrichment of essential fatty acids. The aim of this research is to know the increase of growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil and corn oil. The study used 3 treatments and 3 replications ie A (0% corn oil + 0% fish oil), B (1.5% corn oil + 1.5% fish oil), and C (3% corn oil + 3% fish oil). Parameters observed included specific growth rate, total feed consumption, feed efficiency, fat retention, and survival rate. The supporting parameter is water quality. The data obtained were analyzed by analysis of variance and continued by fisher test with 95% confidence interval. The results showed that there was a significant effect (P <0.05) on the growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil and corn oil. Treatment C (3% corn oil + 3% fish oil) is the optimum dose because it has the best growth performance and best feed efficiency that is specific growth rate (4.67%), total feed consumption (262,9 g), feed efficiency (61% ), fat retention (2.805%), and survival rate (80%).

Abstract

The increase of the growth performance and control of disease can be done by the use of imunostimulan. Immunostimulant is a material that capable of increasing the non-specific immune response of fish. The purpose of this study was to determine the best concentration of immunostimulants in self-formulated pellet feed on the growth performance and immune response of silver pompano fingerling. The immunostimulant content used it was sourced from commercial products Nutricell. There was three concentrations of imunostimulan were used in this study, namely 0.3% (treatment A), 0.5% (treatment B), and 0,0% (treatment K) and one group fish fed with commercial feed as the control and a comparison (treatment P). A total of 840 silver pompano fish seeds with an average initial body weight of 11,13± 1,39 g were kept in 12 cages (0.8 x 0.8 x 0.6 m3) for 30 days. The results showed that the provision of feed supplements containing commercial immunostimulants did not significantly affect the growth rate, The feed conversion and survival rate but produced the highest total leukocyte count of 65,775. x 10. cells/ml and 35.10% phagocytosis rate achieved on the 30th day of treatment. The results of the five-day challenge test showed that treatment A which was the addition of 0.3% immunostimulant feed had lower mortality than other treatments, after being injected with Vibrio alginolyticus bacteria at a dose of 3 x 109 cfu/ml/0.002 g/head fish weight. Based on the results above, it can be concluded that the formulated feed in treatment A which was added with immunostimulant 0.3% (0.7% total in the feed formula) showed a higher survival performance in the nursery phase of silver pompano fish compared to other treatments.

Abstract

Shrimp cultured in Purworejo Village begun in the 1980s. Productivity of shrimp farming in this region, had experienced a peak of success in 1998 with an average production of 200 kg / ha with black tiger shrimp (Penaeus monodon) as the main commodity. Productivity decreases to 120kg / ha then occur due to decreasing environmental quality and susceptible post larvae to disease infections. One effort to increase the productivity of ponds can be done by switching the cultivation of black tiger shrimp to Pacific white leg (Litopenaeus vannamei) shrimp. The purpose of this study was to study the feasibility of semiintensive Pacific whiteleg shrimp cultured. This research was carried out in two shrimp farmer groups namely Sido Makmur and Lestari Gemilang located in Purworejo Village, Pasir Sakti District, East Lampung Regency. The type of research used is a case study and uses descriptive tests. The results showed that Pacific white leg shrimp cultured can produce 10,804,45 kg/3 ha and achieve a profit of Rp. 407.025.500 with a net B/C of 1,7. Moreover, black tiger shrimp culturehas reached 725 kg/5 ha with a profit of Rp. 13.660.000 with net B/C of 1,2. This study concluded semiintensive Pacific whiteleg shrimp is profitable compared toblack tiger shrimp cultured. It is also feasible to be developed by the village community.
