Abstract

The use of automatic feeding equipment can increase the productivity of vannamei shrimp cultivation and harvest yields. This research aimed to determine which of the three feeding methods (manual, 120° autofeeder, and 360° autofeeder) produces greater growth and production results for vannamei shrimp. The shrimp used came from Sura Tani Pemuka which were stocked from 23-25 July 2022 at PL (post larval) age 11. When using a 360° autofeeder with a total area of 5,880 m2 and a density of around 169 individuals/m2. When using a 120° autofeeder with a total area of 2,840 m2 and a density of around 166 fish/m2. The manual method is used with a total area of 2,500 m2 and a density of around 187 individuals/m2. The research method was carried out by means of descriptive observation and analysis. Data collection was carried out during shrimp sampling activities, checking water quality, and harvesting. The research results showed that the use of a 360° autofeeder, 120° autofeeder, and manual resulted in sequential growth performance including: survival rates of 39.37%, 51.47%, and 32.47%; average weight growth of 21.53 gr/head, 17.47 gr/head, and 10.12 gr/head; daily weight growth of 0.31 gr/day, 0.25 gr/day and 0.16 gr/day; and, feed conversion ratios were 1.84, 1.73 and 2.23. The harvest results achieved using the 360° autofeeder, 120° autofeeder, and manual method reached 4558.32 kg, 3670.18 kg, and 1294.965 kg, respectively.

Abstract

Microcapsules are small round particles with uniform walls or layers around them that generally have a diameter from 0.2 to 5000 µm. Microencapsulation is a process that converts solid or liquid materials into capsule form which aims to protect and maintain active ingredients from environmental influences such as humidity, high temperature, light exposure, or oxidation processes. Microcapsule formation can be done using the crosslink method. Microcapsule size is affected by the stirring speed of the encapsulator machine. During microencapsulation of fish meal with eggs and gelatin using the crosslink method, the stirring speed is 3000 rpm, 3500 rpm, 4000 rpm, 4500 rpm, and 5000 rpm. In the microencapsulation process of fish meal with eggs and gelatin, the smallest average diameter at a speed of 5000 rpm, which is 18.220 ± 3.3 µm and has a yield of 26% while the largest diameter at a speed of 3000 rpm, which is 33.53 ± 4.8 µm and has a yield of 28.4%. Based on the results of the Tukey SPSS test, the speeds of 3000 rpm (33.53 ± 4.8 µm), 3500 rpm (30.25 ± 4.4 µm), 4000 rpm (26.30 ± 3.5 µm), 4500 rpm (22.50 ± 4.1 µm), and 5000 rpm (18.220 ± 3.3 µm) were very significantly different (P <0.05) in each treatment.

Abstract

Eel (Anguilla sp.) is a leading freshwater fish commodity. In the intensivesystem, high stocking density results in high production costs. Maggot meal isan alternative raw material that has complete nutritional value such as fishmeal but is cheaper. The purpose of this study was to determine theeffectiveness of substituted fish meal with maggot meal on the growth andsurvival rate (Anguilla bicolor) Elver phase. The method carried out in thisstudy used an experimental method with a completely randomized design(CRD) consisting of 4 treatments and 3 replications with a combination of fishmeal and maggot meal, P0: 100% TI and 0% TM, P1: 80% TI and 20% TM,P2: TI 60% and TM 40% and P3: TI 40% and TM 60%. The results of rearingfor 60 days showed a significant effect on absolute weight growth, specificgrowth rate, and yield, while the yield had no significant effect on absolutelength growth, feed conversion, and survival. The results of the water qualityparameters of the media are temperatures ranging from 24 °C -29,8 °C, pHranging from 5,14-7,7, DO ranging from 2,4 mg/l – 5,1 mg/l and ammoniaranging from 0 ppm – 0,01 ppm.

Abstract

The growing demand for catfish in the market is prompting farmers to consistently enhance their production capacity. Several obstacles are encountered during production growth, such as pathogen attacks, suboptimal growth, and low survival rates. This study aimed to determine the effectiveness of Minaraya probiotics with different doses in feed on the growth and immune response of catfish. The method used in this study was an experimental method with a completely randomized design (CRD) consisting of four treatments: control (without probiotics), and treatments P1, P2, and P3 with the addition of Minaraya probiotics at 2, 5, and 10 mL per 2.5 kg of feed, respectively, each with three replications. The parameters observed included survival rate, SGR, DGR, FCR, PER, AF, RB, and leukocyte differentiation. The results showed that the survival rate in all treatments was relatively high, ranging from 95% to 98.89%. The results also showed that the addition of Minaraya probiotics significantly (p<0.05) increased growth parameters (SGR and DGR) and feed efficiency (FCR and PER), with the best dose being in treatment 3 (P3) at a dose of 10 mL/2.5 kg of feed. On the other hand, the non-specific immune response also increased in the treatment given Minaraya probiotics, as indicated by increased phagocytic activity, respiratory burst, and proportion of lymphocytes, neutrophils, and monocytes, as well as an increase in the total number of erythrocytes after Aeromonas hydrophila infection. The application of Minaraya probiotics in a sustainable cultivation system can improve catfish productivity and health.
