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.

Abstract

Parasites in the body of cultivated fish will cause harm to the fish, because the parasites take nutrients from their hosts, it is necessary to study the intensity and prevalence of parasites in tilapia (Oreochomis niloticus) in order to determine the density of parasite attacks and the percentage of parasites in tilapia. Samples of tilapia (Oreochomis niloticus) were taken from the Central Sangeh Fish Seed Center (BBI). The research was conducted for 3 months from October 4th 2022 to December 13 2022 randomly sampling. Samples of tilapia (Oreochomis niloticus) examined were 36 samples of Nila Nirwana fish. The parasites found in the external organs (ectoparasites) were only found in the tilapia gills, while for the internal organs (endoparasites) parasites were not found in both the stomach and intestines of the fish. The ectoparasites found were Dactylogyrus sp. (2181 ind) and Gyrodactylus sp. (157 ind). The highest intensity was in the genus Dactylogyrus of 60.6 ind/fish including the severe category, while for the genus Gyrodactylus of 4.4 ind/head including the low category. The highest prevalence value was in the genus Dactylogyrus with 92% in the always category while in the genus Gyrodactylus it was 78% in the usual category. This study’s supporting data for water quality includes temperature, pH, DO, and ammonia. Where temperature during the study ranged from 28-30oC, pH or acidity ranged from 7.6-8.5, and DO or dissolved oxygen ranged from 7.3-8.4 mg/L. The water quality result in this study were normal for fish farming.
