Abstract

Many freshwater fish farming activities are carried out to meet the increasing demand for fish consumption. One commodity with high market demand is African catfish (Clarias gariepinus). The success of cultivation activities is the maintenance of broodstock is very influential on the eggs production. It is necessary to pay attention to the nutrients in the feed during cultivation. This study aims to determine the effect of adding soybean oil to feed on hatching eggs carried out at the Regional Technical Implementation Unit (UPTD) of Freshwater Aquaculture, Denpasar City. African catfish (C. gariepinus) were fed twice a day with feed mixed with soybean oil with three treatments namely 0%, 3% and 5% for five months. The fecundity and hatchability of eggs were calculated using a 10x10cm transect and analyzed using ANOVA analysis. Water quality observations were carried out once a week and ammonia at the end of each month. The results of this study obtained that fecundity values ranged from 214-546 grains/transect and egg hatchability values ranged from 0-62,62%. The results of observations of water quality showed a value that could still be tolerated by African catfish during the study. These results indicate that adding of 3% soybean oil to the broodstock feed of African catfish helps to increase the quality and quantity of hatching eggs.

Abstract

Mackerel (Rastrelliger sp.) is a pelagic fish commodity that has high economic value because mackerel is a consumption fish and is easily found in all sea waters in Indonesia. Mackerel is a fish that is hunted for consumption because of its high omega-3 content, so it is really necessary for us to pay attention to the quality of the mackerel from the threat of parasites that can cause disease. This research was being conducted to determine the distribution of endoparasite microhabitats, intensity, prevalence, and the relation between the length of the fish and weight of fish with the number of parasites. The research samples were collected from Kedonganan Fish Landing Base, Badung, Bali, which was carried out from October 2021 to November 2021. The research used a descriptive quantitative method and the sampling method was carried out by random sampling. The total samples of fish examined were 35 fish consisting of two species, R. Kanagurta (20 fish) and R. brachysoma (15 fish). Endoparasites of the Anisakis genus were parasites with the highest intensity and prevalence values : 4,06 ind/fish and 82,86% with a low infection rate. The relation between the length of the fish and body weight of fish with the number of parasites was in the opposite direction and had a very low effect with a value of correlation (r) between length and the number of parasites are 0,031 and a value of correlation (r) between weight and number of parasites are 0,00547.

Abstract

Giant prawns are one of the freshwater aquaculture commodities with high economic value. The high demand for giant prawns is constrained by the low quality of larvae, which affect the prawn growth to reach consumption sizes. Conventional efforts have been made to treat the bacterial diseases in the prawn cultivation using antibiotics. However, it has risk of causing pathogenic bacteria to become resistant to antibiotics. Such issue can be overcome by using inhibiting quorum sensing from pathogenic bacteria, especially thiophenone compounds. This study aimed to determine the effect of adding thiophenone compounds on the survival and growth of giant prawn larvae from Center for Giant Prawns (BBUG) Klungkung, Bali tested with Vibrio harveyi. A completely randomized design of 4 treatments (A: control, B: Larvae and Vibrio harveyi (105 CFU/ml), C: Larvae and thiophenone (10µM), D: Larvae, thiophenone (10µM) and Vibrio harveyi (105 CFU/ml)) and 3 repetitions was done in laboratory. A total of 12 experimental units containing 20 larvae with 0.2liter seawater media at 28?C. The results showed that the survival rate of giant prawn larvae was significantly higher when the larvae challenged with Vibrio harveyi compared to un challenged larvae. Furthermore, there was no difference in prawn larvae growth between the treatments indicated by similar value of Larvae Stage Index (LSI). This study has demonstrated the benefit of employing thiophenone compounds to improve the quality of giant prawn larvae. Further study in challenging the thiophenone compounds with other bacteria that might threat the giant prawn growth is still needed.

Abstract

White snapper (Lates calcarifer) is one of the marine aquaculture commodities in Indonesia, which has high economic value and fast growth. This study aims to investigate the influence of Saccharomyces cerevisiae addition into feed on the growth of white snapper (Lates calcarifer). The growth observed was the absolute length growth, the absolute weight, feed conversion ratio, survival, and specific growth rate. This research used experimental methods with complete randomized design non-factorials. White snapper (size 2-3 cm) was maintained for 30 days at a stocking density of 1500 Ind/m3. There were 2 treatments conducted, K treatment (control) and S treatment (pellet + Saccharomyces cerevisiae 100 ml/kg feed). Data analysis was done using t-test. The result showed that the addition of Saccharomyces cerevisiae resulted in decreasing of feed conversion ratio. The absolute length and weight, specific growth rate and survival were higher than the treatment without the addition of Saccharomyces cerevisiae, but not statistically different (p>0,05). The S treatment resulted in higher value of the feed conversion ratio (2,28), growth (7,21 cm/month), absolute weight growth (13,75 g/ month), the specific growth rate (11,92 % /day) and survival of (84,07 % /month). Water quality values such as temperature ranged from 29-31,6 OC salinity 27-32 ppt, pH 7,11-7,57, and dissolved oxygen 1,74-5,64 ppm.
