Abstract

Guppy fish is one type of ornamental fish which is in great demand due to its interesting color variations. Color of ornamental fish will be brighter if the feed contains color pigments. The study aims to determine the effect of Astaxanthin supplement in pellets on the color brightness of guppies and to find the best dose of Astaxanthin supplement in pellets on the color brightness of guppies. The method used in the study was complete randomized design (CRD) consisting of five treatments (Astaxanthin supplements of 0%, 2%, 3%, 4% and 5%) and three replications. The experimental fish were male guppy fish Strain HB Red ± 3 cm length with a density of 3 fish/aquarium. Feeding was done twice a day and siphoning was done every afternoon. The parameters observed were Chroma value, survival rate and water quality. The results show that the supplement of Astaxanthin in pellets successfully increase the brightness of guppies and the best dose of Astaxanthin supplement in pellets was 5% with an increase in Chroma value of 4.82%. The survival rate obtained was 100%. Water quality includes an average temperature of 26-27 ℃ and pH of 6-7 and dissolved oxygen (DO) was 6.95-7.93 ppm

Abstract

The high cost of commercial feed in Nirwana tilapia aquaculture leads to elevated production costs and reduced profits. As a solution, the provision of natural feed is proposed as an alternative to reduce production expenses. This study aims to compare the growth of Nirwana tilapia fed with three different natural feeds: Tubifex sp., Chironomus sp. larvae, and maggots. The experiment was conducted using a completely randomized design with three replicates for each treatment. The feeding rate was 3% of the fish’s body weight, administered three times a day. The parameters measured included absolute biomass, absolute length gain, daily growth rate (Specific Growth Rate, SGR), survival rate (SR), and water quality during the 30-day rearing period. The results showed that feeding Nirwana tilapia with Tubifex significantly increased growth compared to the control group (commercial pellets), Chironomus larvae, and maggots. The absolute biomass from Tubifex feeding was 5.23 ± 0.89 g, absolute length was 4.2 ± 7.8 cm, SGR was 1.52 ± 0.33%, and SR was 90%. The next highest growth was seen in Chironomus larvae, followed by maggots, with the control yielding the lowest results.

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.
