Abstract

Aquaculture is an activity to cultivate aquatic biota in controlled media. One of the cultivated fish resources is tilapia (Oreochromis niloticus). Tilapia production continues to be increasing to meet increasing of consumer demand. The emergence of the problem of organic matter levels in the water could be harmful to both of fish and the environment. One of the solution to overcome this problem is by application of biofloc technology. The purpose of this study was to determine the diversity and composition of plankton species in tilapia biofloc ponds in Tiga Village, Susut District, Bangli Regency. This research was conducted in March-May 2021 in Tilapia Biofloc Pond. The research used a simple random sampling method. Sampling was carried out once in three biofloc ponds where each pond had 5 points. Data analysis is using the Microsoft Excel program. The data is present in the tables and charts consisting of the abundance, diversity, composition, dominance, and uniformity index of plankton. Based on the research results, it is known that there are 12 genus of phytoplankton and 4 genus of zooplankton. Phytoplankton diversity index values ??ranged from 1.31 to 1.65. Zooplankton diversity index values ranged from 0.79 to 1.08. The composition of phytoplankton species came from the genus Scenedesmus, Chlorella, Coelastrum, Chroococcus, Gonatozygon, Pediastrum, Nitzschia, Navicula, Synedra, Triceratium, Chaetoceros, and Pesudanabaena. The composition of zooplankton species comes from the genus Brachionus, Euchlanis, Tokophyra, and Vorticella. The water quality measured during the study was a temperature value ranging 25 oC, a pH value ranging from 7,12 – 7,18, a DO value ranging from 6.6 to 6.9 mg/L, an ammonia value ranging from 1.41 to 1.51 mg/L, and a nitrate value ranging from 1.84. -3.69 mg/L. This value is still in the optimal range for plankton life.

Abstract

Vannamei shrimp (Littopenaeus vannamei) known as white shrimp is widely cultivated in Indonesia because it has high economic value. Conventional cultivation of vannamei shrimp is often represented by poor sewage treatment, where aquaculture waste is discharged directly causing a decrease in water quality in the environment. This study used 2 different cultivation systems, namely RAS (Recirculating Aquaculture System) and conventional systems (flow-through system). The research located at BPIUUK Karangasem, Bali. Water quality monitoring in each tank was carried out including ammonia, nitrite, TSS (Total Suspended Solid), and the abundance of microbes. Measurement of weight and length starts from the age of 30 days of shrimp with further checks every 7 days. A sampling of water quality, as well as measurements of weight and length, were carried out by random sampling method in each rearing tank. Based on the research data, the quality of aquaculture water using RAS and conventional system were not significantly different. The data on the abundance of microbes obtained in cultivation using RAS and conventional were also not significantly different, where RAS reaching 2.0 x 105 cfu/mL, while in conventional system was obtained 2.1 x 105 cfu/mL of total bacteria count. The growth rate with the average value of ADG (Average Daily Growth) in RAS is 0.88 g slightly higher compared to it is 0.80 g in conventional system. This study concluded that cultivation using RAS and conventional by flow-through system were not significantly different in terms of water quality, microbial abundance, and shrimp growth rate.

Abstract

Abalone is one of the sea snails that have high economic value and has advantages because it has a high protein content of 71.99%, a fat content of 3.24%, and can be used as medicine. The high demand for abalone causes the increase of wild capture and lead to scarcity of abalone in the waters. One way to overcome this problem is by cultivate the abalone. Abalone cultivation can be done with a monoculture system. One of the technologies applied is by using a recirculation aquaculture system (RAS), which is reprocessing the water used so that it can be reused for cultivation activities. The purpose of this study was to analyze the parameters of water quality, growth length, weight and survival of abalone (Haliotis squamata) seeds using the RAS system. The research was conducted in June – September 2020 at the Shrimp and Shellfish Parent Center, Karangasem, Bali. The research was performed by purposive sampling method. The water quality parameters data such as nitrite, ammonia, TSS pH, temperature, DO, and salinity were taken. The results of the measurement of water quality are nitrite 0 – 0.338 mg/L, ammonia 0 – 0.09 mg/L, TSS 0 – 15 mg/L, pH 7 – 8, temperature 26 – 28 oC, DO 4.3 – 7.07 mg/L, and salinity 31 – 38 ppt. Those values are still in the optimal range for abalone culture. The growth in length and absolute weight of abalone seeds during the study were 25.17 mm/ind. and 9.15 g/ind., respectively, and the survival value was 99.5% during the 100-day culture period.

Abstract

Swordfish (Trichiurus lepturus) with the local name Layur is one of the demersal fish commodities that has high economic value because it is an export commodity with high omega 3 content.. The high demand for layur fish must be supported by good fish quality and quality. The quality control is needed related to fish diseases, one of which is fish parasites. Endoparasite infection in marine fish can be zoonotic and dangerous if consumed by humans. This research was conducted to determine the intensity, prevalence, abundance and correlation of fish sex with the number of endoparasites. The research sample was obtained from the Kedonganan Fish Market, Bali which was held from September 2022 to November 2022. The sampling method was carried out by purposive sampling by paying attention to the secondary sexual characteristics of the swordfish. The total sample of fish examined was 36 fish consisting of 18 male fish and 18 female fish. Endoparasites of the genus Acanthobothrium were parasites with the highest intensity and abundance values, namely 46.05 ind./fish and 28.14 ind./fish, while the highest prevalence value was obtained from the Genus Lecithochirium of 86.11%. The correlation between fish sex and the number of endoparasites was analyzed using the Mann – Whitney test with an Asymp value. Sig 0.506 and Z value -0.665. These results showed an insignificant relationship (p > 0.05) between the sex of the fish and the number of endoparasites in the whitefish that were sampled in this study.

Abstract

Tilapia is a type of fish favored by freshwater fish consumers because it is easy to cultivate. The problem faced in freshwater fish farming activities is the high price of artificial feed. To deal with these problems, alternative feeds are needed to reduce the use of artificial feeds such as sudden apu wood (Azolla pinnata). This study aims to determine the effectiveness of the sudden apu wood (Azolla pinnata) on the growth and survival of tilapia (Oreochromis niloticus) and to help fish farmers reduce the use of artificial feed. The research method used is an experimental approach method. The experimental design in this study was a Randomized Block Design (RAK) which consisted of 3 treatments with 3 replications. Treatment A (direct feeding of 100% Azolla pinnata plants), Treatment B (direct feeding of 50% Azolla pinnata plants and 50% pellets), and Treatment C (100% pellet feeding). The results showed the absolute weight growth of treatment A 12.18±5.66 g, treatment B 17.73±4.40 g, treatment C 24.53±3.80 g. The absolute length growth of treatment A was 2.22 ± 0.60 cm, treatment B 2.54 ± 0.40 cm, treatment C 3.50 ± 0.37 cm. The survival rate of treatment A was 66.67±11.54%, treatment B and treatment C were 100±0%. Feed conversion ratio (FCR) for treatment A 4.8±2.28, treatment B 2.1±0.45, treatment C 1.7±0.17. The water quality of the three feeding treatments had no significant effect on pond water quality and was still within the optimal range for tilapia growth and cultivation.
