Abstract

Indonesia is the second largest supplier of white shrimp (Litopenaeus vannamei, Boone 1931) in the USA market. Hence, the need for its sustainable production and improved growth. Probiotics, among others, are known for their growth enhancing attributes. Therefore, this study was conducted to determine the effects of powder and liquid probiotics on the growth of white shrimps at the Minaloka Jaya shrimp ponds, Grabag District, Purwerojo Regency, Central Java. The shrimps were cultivated for 60 days and applied with three probiotic treatments, namely commercial liquid probiotics with dosage of 10 mL/kg feed, powder probiotics with dosage of 10 g/kg feed and liquid probiotic with dosage of 10 mL/kg feed. Each probiotic preparation was administered four times a day to over 150,000 vannamei shrimps which were cultured in a semi-intensive system. Probiotics in powder and liquid forms contain Lactobacillus fermentum, L acidophilus, L. plantarum, L, curvatus, Bacillus licheniformis, B. subtilis, and B. polimyxa. B. megaterium, B. coagulans, Pseudomonasputida, Nitrosomonas sp. and Nitrobacter sp. Using the Randomized Block Design (RBD), the three treatments were replicated five times. The application of probiotics in both powder and liquid forms had increased the growth yield of the vannamei shrimp. However, the powder probiotic had shown better growth performance than the commercial liquid probiotics and liquid preparation of probiotics. Probiotic powder form provides a specific growth rate (SGR) of 8.18%, absolute body length of 9.68 cm, absolute biomass of 6.78 g, and feed conversion ratio (FCR) of 1.93.

Abstract

The aim of this research was to analysis the effect of different aquaculture systems on the water quality in cultivation of catfish (Pangasius hypophthalmus). This research was conducted at Fourth Building Hatchery Faculty of Fisheries and Marine Sciences of Padjadjaran University from June to August 2017. The research was using Completely Randomized Design (CRD) with three treatments and four replications. The Treatment A were cultivation in recirculation system, treatment B cultivation on biofloc system, and  treatment C cultivation  in conventional system (control). The parameters of this research are absolute growth rate and water quality include temperature, acidity (pH), dissolved oxygen (DO), nitrate, ammonia and phosphate. Data were analyzed using the Fingerprint Analysis Variety and followed Duncan's Multiple Range Test at the level of 95%. The results showed that the modification of the cultivation system had an effect on the growth rate of catfish. The results showed that the highest absolute growth was in treatment B that is 5.3 gram. The most effective cultivation system in producing water quality in cultivation of catfish is the recirculation system. This can be seen from the low ammonia concentration value of 0.00268 mg/L, phosphate 0.45 mg/L and nitrate 0.31 mg/L at the end of the study.

Abstract

Intensification of culture through stocking densities and high feeding rates can cause water quality problems. Utilization of the recirculation system in intensive cultivation is important to maintain water quality. This study aims to determine the best type of aquatic plants in RAS for the growth of carp fish seeds. The research in January - February 2021. The test fish used were carp fish with a length of 6 - 7 cm and a weight of 3 - 5 gr. The feed used is commercial feed with a protein content of 31 - 33%. Feeding was carried out at 08.00 A.M and 04.00 P.M  with 3% fish biomass. This study used an experimental method with CRD with 4 treatments and 3 replications. Treatment A (Control, without plants), treatment B (cotton fiber, bio balls, activated charcoal and kale), treatment C (cotton fiber, bio balls, activated charcoal and watercress plants) and treatment D (cotton fiber, bio balls, activated charcoal and pakchoy plants). The results showed that the use of different aquatic plants had a significant effect (P <0,05) on SR, SGR, length growth and absolute weight, plant height, and a number of leaves, but no significant effect (P> 0,05) on FCR. The best treatment in this study was B with an SR value of 82,22 ± 7,70%, SGR 4,08 ± 0,14%, absolute length 4,97 ± 0,27 cm, absolute weight 15,81 ± 1,96 gr, plant height 60,67 ± 18,01 cm, number of leaves 20,42 ± 9,66 leaves and FCR 1,10 ± 0,0896

Abstract

The purpose of this study was to determine the effect of submerged cage depth on the growth of green lobsters (Panulirus homarus) in Vietnamese-style cultivation on the East Coast of Pangandaran. The submerged cage was intended so that the lobsters are not disturbed by the situation/water quality in the upper layer of the water. The research method used a completely randomized design using 3 submerge cage depth treatments and 4 repetitions with different ones, A (2 meters); B (3.5 meters); and C (5 meters). Lobster maintenance was carried out for 40 days using a submerged cage with a diameter of 80 cm and a height of 90 cm. Each cage contains 10 lobster seeds measuring 40 g. Frequency of feeding 2 times a day. The amount of test feed given was 20% of the lobster weight each day. Measurement of water quality as supporting data was carried out at the beginning and end of the research. Sampling was done every 10 days and the observed parameters were growth rate, feed conversion ratio (FCR), and feed efficiency (FE). Lobster growth performance showed that treatment C (placement of cages at a depth of 5 meters) was the best among the others, as well as the daily growth rate (LPH) of 1.35%, feed conversion ratio (FCR) of 12.8, and feed efficiency ( EP) of 8.6%. The water quality in the submerged cage with a depth of 5 meters was DO 5.22 mg/L, the water temperature was 28 Celsius, pH was 7 and salinity was 34 ppt.
