The potential of freshwater fisheries in Bangka Regency, Bangka Belitung Province, is sufficient to support fisheries activities in this area. An activity that is quite prominent is catfish farming using swamps and tarpaulin ponds on limited land. In this study, the analysis of cultivation activities was carried out on the Bukit Dempo community group who became partners in the national community service activities, in cooperation with Universitas Airlangga and Bangka Belitung University. Characteristics of the pond using a combination of fixed nets with a net diameter of 0.5 cm. In the pond also found water plants in the form of water hyacinth which is expected to be able to make a symbiotic use of the organic material that has been left behind from feed and catfish waste. The cultivation system is classified as semi-intensive with a combination of commercial feed with high protein (31-33%). The main problem in this cultivation system is low productivity and the lack of technology applied in an effort to increase production efficiency Furthermore, high production yields are marketed to Pangkal Pinang City and also to local areas around the Belinyu sub-district. Technical constraints include Motile Aeromonas Septicemia (MAS) due to the bacterium Aeromonas hydrophylla, which causes about 10% of mortality in commodities before harvest. There has been no treatment action in overcoming the disease, so it is necessary to be careful in avoiding death due to disease by observing catfish at the change of seasons.

Vibrio harveyi infection was an obstacle in shrimp culture. Meanwhile, the use of antibiotics in disease control was no longer effective, so the use of immunostimulants such as meniran leaves was the safest alternative. The purpose of this study was to determine the effect of adding different doses of meniran leaf extract (Phyllanthus niruri L.) to feed on the immune system of vannamei shrimp (Litopenaeus vannamei) which was challenged with Vibrio harveyi. This research was an experimental study using completely randomized design (CRD) consist of 5 treatments and 3 replications, namely, P1 (positive control): commercial feed + V. harveyi infection; P2 (negative control): commercial feed + 0.9% NaCl; P3: commercial feed + 0.5% Meniran leaf extract + V. harveyi infection; P4: commercial feed + 1% Meniran leaf extract + V. harveyi infection; and P5: commercial feed + 2% Meniran leaf extract + V. harveyi infection. The parameters observed were survival and immune response. Immune response analysis was carried out by counting hemocytes, phagocytic activation and total bacteria present in the shrimp intestines at the end of the study. The results of this study indicate that the addition of meniran leaf extract affects the immune system and the viability of vannamei shrimp. In conclusion, the addition of meniran extract to vannamei shrimp feed with a dose of 1% can improve the immune system and viability of vannamei shrimp against vibriosis.

The Diatom of Melosira sp. is one of the potential microalgae candidates for future biofuel resource due to its high lipid profile and fatty acid content, high growth rate, and a quick deposition rate. Salinity stress is one of the environmental factors affecting the growth of microalgae and their lipid content. This research was conducted to identify the response of Melosira sp. treated with different salinity levels on the cell growth rate, biomass productivity, and lipid production. The microalgae cells were incubated for 8 days in 1 liter of F/2 growth medium with different salinity levels from 10 ppt to 35 ppt. Cell’s growth, SGR, biomass, lipid, and water quality factors were measured during incubation. This study revealed that the growth pattern of Melosira sp. cells under various salinities was customarily similar. Observation in the 35 ppt salt presenting the biomass productivity was 711.04 ± 69.38 mg.L-1 with lipid productivity which was 60.49 ± 1.72 mg.L-1. On the other hand, the observation of the lowest salt concentration displaying the biomass productivity was 316.64 ± 16.66 mg.L-1 with the lipid productivity which was 41.46 ± 6.94 mg.L-1. Hence, the results demonstrated that the lower salinity stress in 10 ppt enabled significant cell’s lipid production than the higher salinity of Melosira sp. in F/2 medium. Furthermore, lipid productivity was uncorrelation with biomass production pattern. This information may be useful in optimizing Melosira sp. lipid performance as a supporting knowledge.

Bonylip barb (Osteochillus hasselti) is a favourite freshwater fish, especially in West Java, Indonesia. Cultivation of bonylip barb is carried out in a conventional method; therefore, it is necessary to apply new cultivation technology, namely biofloc. The purpose of this study was to know the growth, feed efficiency, and survival rate of Bonylip barb in biofloc system cultivation (C/N ratio 10) with different stocking densities. This research was conducted in March – July 2021, and the experiment was conducted at the Laboratory of Aquaculture, Faculty of Agriculture, Djuanda University, Bogor. The object of research is bonylip barb seed (size 4.5 – 5.5 cm). The research design was a completely randomized design with three treatments of stocking density {A (10 fish/21 L), B (20 fish /21 L), and C (30 fish /21 L)} with four replications. Parameters observed were specific growth rate, feed efficiency, survival rate, and water quality. Furthermore, data were analyzed using analysis of variance (ANOVA) and LSD test. The results showed that treatment A (stocking density 10 fish/21 L) had the best performance with a specific weight growth rate (2.03 ± 0.15%), feed efficiency (78.7%), and survival rate (100%). Water quality during the study was feasible for bonylip barb life. Keywords: Biofloc, Molasses, Osteochillus hasselti, Specific Growth Rate, Survival Rate

This study was executed to resolve the argument on the growth superiority of three Nile tilapia strain such as, existing strain of Nile tilapia (ESNT), genetically improved farmed tilapia (GIFT) and sex reversed Monosex cultured in brackishwater pond and to comprehend the relationship of water physico-chemical parameters with the growth. Analogous age group of fish each weighing about 0.62±0.09 g with iso-stocking density (5ind./m2) and a culture tenure of 120 days was considered. The physico-chemical variables were at their optimal level over the entire time span of culture. However, all physico-chemical variable beyond alkalinity and ammonia showed strong positive correlation with mean fish weight. The study revealed that, weight gain by GIFT strain was nearly 25.9% and 5.10% higher than Monosex and ESNT strain, respectively. The highest final mean body weight was achieved in the GIFT strain (223±8.60 g) and there was significant difference among the strains. The highest apparent SGR of 16.85%/day was attained in the GIFT strain without significant variation across the strain. GIFT strain gave significantly (p<0.05) higher gross fish yield (9789.70 Kg ha-1) along with best feed conversion ratio (FCR) and survival, whereas they differed significantly among the three strains. The GIFT strain showed closest isomeric growth while the rest two had allotropic growth pattern. Thereby the results established that, strain difference significantly (p<0.05) impacted the growth parameters and GIFT was the best strain. Overall results greatly minimizes the controversy on growth pattern of different strains of Nile tilapia reared in brackishwater ponds, Bangladesh.
本研究旨在解决在咸淡水池塘中养殖的尼罗罗非鱼现有品系(ESNT)、改良养殖罗非鱼遗传改良品系(GIFT)和性别逆转单性罗非鱼生长优势的争论，并了解水体理化参数与生长的关系。在相同的放养密度(5条/m2)和120天的养殖周期下，每条鱼体重约为0.62±0.09 g。在整个培养过程中，理化指标均处于最佳水平。除碱度和氨外，其他理化变量均与鱼的平均体重呈显著正相关。研究发现，GIFT品系的增重比Monosex品系和ESNT品系分别高出近25.9%和5.10%。GIFT菌株最终平均体重最高(223±8.60 g)，菌株间差异有统计学意义。GIFT菌株的表观SGR最高，为16.85%/d，菌株间差异不显著。GIFT品系能显著(p<0.05)提高鱼总产量(9789.70 Kg ha-1)、饲料系数(FCR)和成活率，但3个品系间差异显著。GIFT菌株表现为最接近的异构体生长模式，其余2株均为同素异形体生长模式。结果表明，菌株差异对生长参数影响显著(p<0.05)， GIFT菌株为最佳菌株。总体结果极大地减少了对孟加拉国咸淡水池塘养殖的尼罗罗非鱼不同品系生长模式的争议。

Currently, the problem of increasingly limited land availability has led to increasingly limited cultivation activities. The decreasing number of large cultivation locations requires people to be more creative in utilizing narrow locations and in saving water. Fish farming in buckets is a potential solution for aquaculture in a narrow area with more efficient use of water, easy for the community to do in their respective homes with relatively small capital, and finally able to meet the nutritional needs of the community. The purpose of this study was to determine the growth of tilapia (Oreochromis niloticus) kept in buckets using water spinach plants (Ipomoea aquatica). This research used two treatments, namely P0: control (fish farming in buckets without using plants) and P1: fish farming in buckets using plants. Parameters observed were absolute weight growth, absolute length growth, feed efficiency, and survival. The results showed that the P1 treatment resulted in an absolute weight growth of 3.44 g, an absolute length growth of 1.12 cm, feed efficiency of 93.08%, and survival of 100%. While the P0 treatment resulted in absolute weight growth of 3.92 g, absolute length growth of 1.21 cm, feed efficiency 81.75 %, and survival of 82.5%. Rearing tilapia in buckets without water spinach plants better results than using water spinach plants.

High floc accumulation in intensive catfish culture will increase the bacterial consumption of oxygen and affects the dissolved oxygen in the media is relatively low then affecting the fish growth. For control the floc accumulation is to remove the flock regularly. However, removing a large amount of floc will affect the flock's ability to control nitrogen waste in the water and the utilization of the flock as feed for fish will be minimum. The research was conducted to evaluate of floc volume levels on water quality and production performance of catfish culure in the biofloc system. The research design used a completely randomized design (CRD) with 4 treatments and 3 replications. The research treatments were floc volume level (KVF), namely (KVF) 20-40 ml/L, (KVF) 40-60 ml/L, (KVF) 60-80 ml/L and (KVF) 80-100 ml/L. The results showed that the water quality in all treatment were within the safe level for catfish. (KVF) 60-80 ml/L and 80-100 ml/L had higher survival rates of 100% (P <0.05). The growth rate in (KVF) 80-100 ml/L showed the lowest value compared of other treatments (P <0.05). (KVF) 60-80 ml/L can improve feed conversion ratio and increase protein retention by 59.17%, significantly different compared to other floc level treatment (P <0.05).

For control the floc accumulation is to remove the flock regularly. However, removing a large amount of floc will affect the flock's ability to control nitrogen waste in the water and the utilization of the flock as feed for fish will be minimum.

The COVID-19 pandemic has caused lobster cultivators (Panulirus spp.) in East Lombok Regency to try to fulfill their daily needs by looking for other jobs. The purpose of this study was to determine the impact of the COVID-19 pandemic on the sustainability of the lobster cultivation business in East Lombok Regency. The research method used was descriptive qualitative method based on the data generated during the research. Analysis of the data used in this research was the Net Benefit Cost Ratio to determine the amount of net profit from costs and investments. Stakeholder perceptions were analyzed descriptively. The results of the analysis show that the lobster cultivation business is still feasible to do, so it can be concluded that the COVID-19 pandemic has no impact on the sustainability of the lobster cultivation business in East Lombok Regency. To maintain the continuity of lobster cultivation in East Lombok Regency, it is necessary to ensure the availability of feed and guarantee access to marketing.

The purpose of this study was to determine the administration of Caulerpa racemosa extract in clinical sign and intestinal histopathological profile of whiteleg shrimp (Litopenaeus vannamei) after infected by Vibrio parahaemolyticus. The study was conducted using a completely randomized design (CRD) with six treatments and three replications. Shrimp were divided into six groups, two control groups without the administration of C. racemosa extract, the other four groups with the administration of C. racemosa extract with successive doses; 30 mg/kg (P1), 60 mg/kg (P2), 120 mg/kg (P3) and 240 mg/kg (P4) through feed. On the 15th day of rearing, the control group was divided into two groups: negative control (K-) was injected with PBS and then positive control (K+) and four other treatments (P1, P2, P3 and P4) were infected with V. parahaemolyticus. The results showed that intestinal damage caused by V. parahaemolyticus infection were inflammation and necrosis. The administration of C. racemosa extract had a significant effect on the histopathological profile of the whiteleg shrimp intestine. The lowest percentage of damage was found in the P4 treatment, which was 19.6% with a indication of low damage. Clinical sigs appeared at 48 hours post-infection pale hepatopancreas, empty intestines, reddened uropods and gnats. From this study, it can be concluded that the administration of C. racemosa extract to the feed at a dose of 240 mg/kg is the best dose in reducing the level of damage to the intestinal organs of whiteleg shrimp infected with V. parahaemolyticus.
