Abstract

The high price of fish meal is also a reason for alternatives and better protein sources. This research aims to substitute fish meal with maggot meal in feed for snakehead fish's growth rate and survival. The method used in this research is the experimental method of Completely Randomized Design (CRD), which consists of five treatments and three replications. The treatments used were (A) without the use of maggot flour (control), (B) 15% maggot flour substitution, (C) 30% maggot flour substitution, (D) 45% maggot flour substitution, (E) 60% maggot flour substitution, which was maintained for 50 days. The test fish used were snakehead fish with a 9-10 cm length and weighing 7-9 g. The container used is an aquarium with dimensions of 40x26x28 cm3 or a water volume of 15 L, in which five snakehead fish are placed in each aquarium. The amount of feed given is 5% of the fish biomass. The results obtained during the research showed that treatment E with the substitution of fishmeal for maggot meal at 60% of the feed resulted in the highest absolute length growth of 4.0 cm, the highest specific growth rate of 2.54%, and survival of 87%.

Abstract

The purpose of this study was to determine the optimum content of the addition of curcuma flour with different doses to the feed on the growth of gourami fry (Osphronemus gouramy). The method used in this study was a completely randomized design (CRD) experimental method, which consisted of 5 treatments with 3 replications. The treatment used was treatment (A) without giving curcuma flour (control), (B) giving curcuma flour at 2.5%/kg feed, (C) giving curcuma flour at 5%/kg feed, (D) giving curcuma flour ginger at 7.5%/kg feed, (E) giving curcuma flour at 10%/kg feed. The results of analysis of variance (Anova) showed that the addition of the flour at different doses had a significant effect (P<0.05) on the growth of gouramy fish fry. The results showed that the addition of curcuma flour at 7.5%/kg of feed gave the best results with the highest absolute weight growth of 15.11 ± 0,42 g, the highest absolute length growth of 3.92 ± 0,42 cm, the feed conversion ratio of 1.95 ± 0.11, and survival of 100%. Keywords: Gouramy fish, curcuma flour, growth, feed.

Abstract

The prevention of fish infections caused by Aeromonas sp. bacteria can be achieved using Lactobacillus sp. bacteria. This study aims to identify and analyse the effect of Lactobacillus sp. using the microencapsulation method to treat catfish infected with Aeromonas sp. The identification of Lactobacillus sp. bacteria was conducted through microbiological and molecular tests. After obtaining the test results, the research continued with the application of microencapsulation using the emulsion technique. The impact of this microencapsulation was evaluated on catfish through an experimental approach employing a completely randomised design (CRD), with 10 catfish tested in each experimental aquarium. The study included five treatments, designated as A, B, C, D, and E. Treatment A served as the control, without the administration of Lactobacillus. Treatment B involved the application of Lactobacillus without microencapsulation. Treatments C, D, and E utilised varying doses of Lactobacillus at 0.003, 0.005, and 0.007 g/L, respectively. Each treatment was conducted in triplicate. Microbiological and molecular testing identified encapsulated Lactobacillus sp., specifically Lactobacillus helveticus and Lactobacillus johnsonii. The results indicated that treatment D, comprising a dose of 0.005 g/L of Lactobacillus helveticus and Lactobacillus johnsonii, was the most effective in promoting the healing of catfish infected with Aeromonas hydrophila bacteria.Keywords: Completely randomized design, bacterial infection mitigation, probiotic bacteria, emulsion technique.

Abstract

Decreased water quality can be caused by fish losing their appetite, resulting in a buildup of food waste in the water. One of the additional ingredients that can be used is brackish snail (Faunus ater) flour. This research aims to determine the effect of adding brackish snail (Faunus ater) flour to feed on the growth of African catfish seeds and the appropriate dosage in feed that can increase the growth of African catfish seeds. The method used in this research was experimental with a Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications. The treatments used were (P0) control, (P1) 10% brackish snail (Faunus ater) flour, (P2) 15% brackish snail (Faunus ater) flour, and (P3) 20% brackish snail (Faunus ater) flour. The test fish used were African catfish fry weighing 3-4 g and 5-7 cm long. The container used is waring with a density of 20 fish per pond. The amount of feed given is 5% of the biomass of African catfish seeds. The observation data were analyzed using Analysis of Variance (ANOVA) with the F test at a test interval of 5%, if there were significant differences, continue with Duncan's multiple range test. The results showed that the addition of 10% brackish snail (Faunus ater) flour gave significant results with the highest absolute length growth of 13,3 ± 0,18 cm, the highest absolute weight growth of 36,2 ± 0,18 g, the highest survival of 98,3 ± 2,8%, the lowest feed conversion ratio was 1,1 ± 0,0.Keywords: Brackish snail flour, catfish seed, feed conversion ratio, growth, survival rate

Abstract

Essential fatty acids play a crucial role in fish growth and health. A quality feed containing the right amount of fats can promote fish growth and support metabolic functions. Fatty acid requirements vary depending on the fish species and habitat, with freshwater fish tending to require more n-6 fatty acids, while marine fish require more n-3 fatty acids. The use of fat in feed should be well regulated, as too high levels can interfere with the digestive and metabolic processes of the fish. The use of fish oil mixed in feed as much as 1.5% can help improve the growth performance of carp. Magot oil mixed into the feed as much as 15%/100 g gives the best growth performance in carp. Soybean oil used as much as 10% in feed can increase the content of omega 3, EPA, and DHA in catfish meat. Coconut oil used in feed at 6% proved to have a good impact on the DHA content of tilapia. The purpose of this paper is to review the literature on the role and function of fatty acids in fish growth
