Abstract

This study aims to investigate the effect of the different concentration of RABAL (yeast and lactic acid bacteria) probiotics on the survival, feed conversion, growth and intestinal cells changes of tiger shrimp Penaeus monodon Fab. larvae. This study used a Completely Randomized Design (CRD) method with 4 treatments and 4 replications. Tiger shrimp with average size of 0.02 g was randomly stocked in each container containing RABAL with concentration of 0 ppm (A/control), 75 ppm (B), 150 ppm (C), and 225 ppm (D) with frequency once a day for 30 days. Data were analysed using one way ANOVA. The result showed that the application of RABAL with different doses into the shrimp culture media significantly influences (P0.05) the growth and food conversion ratio of tiger shrimp feed but did not significantly affect (P 0.05) on the survival rate. The value of water quality parameters in this study were still at normal levels for tiger shrimp rearing. As conclusion, the application of probiotics RABAL with different concentrations have positive effect on the absolute weight, absolute length, specific growth rate, feed conversion ratio and intestinal villi surface area of tiger shrimp larvae, without adverse effect on the survival rate of tiger shrimp seed.

Abstract

This study aims to investigate the type, prevalence, and intensity of endoparasites infecting the organs of blood cockles (Anadara granosa) in the waters of Aceh Besar, Indonesia. A purposive sampling method was conducted from March to August 2020 consisting of two sampling sites, namely the waters of Ujung Pancu and Krueng Raya. Endoparasite identification and analysis was carried out at the Parasite Laboratory of the Fish Quarantine Center, Quality Control and Safety of Fishery Products in Blang Bintang, Aceh Besar. The results showed that there were two types of endoparasites living in the blood cockles: namely, Perkinsus sp., which belong to the group Protozoa, and Spiroxys sp. of the Nematode class. The prevalence levels of Perkinsus sp. was 73.33% and were found in the waters of Ujung Pancu; while the lowest prevalence level was 20% in blood cockles that were infected with Spiroxys sp., which were found both in Ujung Pancu and Krueng Raya. The highest intensity level was infections of Perkinsus sp. with a value of 89 ind/species in the Krueng Raya site. The lowest intensity value was infections of Spiroxys with a value of 2 ind/species in Krueng Raya and 2.3 ind/species in Ujung Pancu

Abstract

This study was conducted to determine the effect of water salinity changes on methionine content in tiger grouper juvenile (Epinephelus fuscoguttatus). A total of 2,560 tiger grouper juveniles were used and divided into five groups consist of 1 control group (without exposed to salinity changes) and 4 treatment groups. The salinity was changed every 2, 3, 4, and 6 hours in treatment A, B, C, and D, respectively. Salinity levels were changed during 24 hours by lowering salinity level from 32 psu to 22 psu. Twenty five of fish were collected from each treatment for methionine content analysis. Data were analysed using one way analysis of variance (ANOVA). The results showed that there was a decrease in methionine content in all treatments. A significant decrease (P0.05) of methionine content in treatment A, B, and C were observed after 20 hours (1.15%), 18 hours (1.27%), and 16 hours (1.24%), respectively. While at 0 hours (control), the methionine content was 2.02%. Methionine level in treatment D was not significantly different (P0.05) compared to control group. As conclusion, rearing the tiger grouper juvenile with salinity fluctuations every 6 hours did not lead to methionine deficiency.
