Pangasianodon hypophthalmus grows well in a dark tank completed with an aquaponic system. To improve the growth, a feed supplement made from Moringa oleifera might be used as it is rich in protein, vitamins A, B, C, and minerals. To understand the effect of M.oleifera addition in the feed of fish, research has been conducted in June-July 2022. M. oleifera leaves were dried and powdered and then mixed with commercial fish feed pellets. There were 4 treatments of M. oleifera dosages, namely T0 (no M. oleifera), T1 (10 g/kg), T2 (15 g/kg), and T3 (20 g/kg). The fish was reared in a 100L container (30 fishes/tank, around 4 g BW and 8 cm TL), covered with a dark-colored tarp, and completed with the aquaponic system using Ipomoea aquatica. The feed was given 2 times/day, ad libitum. Samplings were conducted once/10 days, for 40 days. Results showed that the survival of fish in all treatments was 93.3 – 98.89%. The growth of fish, however, was different. There was no difference in fish body weight (BW), total length (TL), and specific growth rate (SGR) of fish fed with Moringa, they were around 23.5 g BW, 5.8 cm TL, and 4.3 cm SGR respectively. While those of the control fish were 13.0 g BW, 4.23 cm TL, and 2.89% per day SGR respectively. The fish that was fed with Moringa-enriched pellets showed the highest Feed Efficiency (90.42-97.46%) and the lowest FCR (1.03 – 1.11). While in the fish that was not fed with Moringa showed the lowest FE (75.48%) and the highest FCR (1.33%). Data obtained indicate that Moringa positively improves the growth of fish as well as improving feed efficiency
浅眼穿梭鱼生长良好，在一个黑暗的水箱完成了水共生系统。辣木富含蛋白质、维生素a、维生素B、维生素C和矿物质，因此可以添加以辣木为原料的饲料来促进生长。为了了解在鱼类饲料中添加油油菌的效果，研究人员于2022年6月至7月进行了研究。将油橄榄叶片干燥并制成粉末，然后与商品鱼饲料颗粒混合。4个处理，分别为T0(无油油菌)、T1 (10 g/kg)、T2 (15 g/kg)和T3 (20 g/kg)。将鱼饲养在一个100L的容器中(30只鱼/缸，体重约4克，长约8厘米)，用深色防水布覆盖，并使用水培系统完成。饲喂2次/天，可随意饲喂。采样1次/10 d，共40 d。结果表明，各处理鱼的成活率为93.3 ~ 98.89%。然而，鱼的生长情况却不同。饲喂辣木对鱼体重(BW)、总长度(TL)和特定生长率(SGR)无显著影响，分别为23.5 g BW、5.8 cm TL和4.3 cm SGR。对照组分别为13.0 g BW、4.23 cm TL和2.89% / d SGR。饲粮添加辣木微丸的饲料效率最高(90.42 ~ 97.46%)，饲料效率最低(1.03 ~ 1.11)。而未饲喂辣木的鱼，其FE最低(75.48%)，FCR最高(1.33%)。结果表明，辣木对鱼的生长有积极的促进作用，并能提高饲料效率

Kabupaten Sumbawa Barat sea (KSB) is included in WPPNRI 573, including the Sawu Sea area, Indian Ocean waters, western Timor Sea, southern Java waters, and southern West Nusa Tenggara (KKP, 2014). The potential for demersal fish is in second place after pelagic fish with a total production of 103,501 tons from the potential fishery resources of WPPNRI 573 of 929,330 tons. An increase in catches that exceeds the sustainable potential value will reduce the catches of the next cycle and even have the potential for the extinction of fishery resources. So it must be overcome by making arrangements for the fishing effort to match the carrying capacity of the resource. The purpose of this study was to determine the sustainable potential of demersal fisheries and their level of utilization in West Sumbawa Regency. The methods used in the preparation of this study are field surveys and descriptive methods. The data obtained were analyzed statistically and descriptively, estimating fish stocks using the Schaefer Surplus Production Model. The results showed that the relationship between effort and CPUE obtained a linear equation y=8809-4.425x with R=0.024 which means that there is no relationship between fishing gear and catch. The catch is influenced by external factors such as seasonality and oceanographic conditions. The optimum effort value is 19,489.91 trips per year and the maximum sustainable catch is 8,584,332 kg per year. The last year's utilization rate value was 0.01% with an effort level value of 0.01%. The utilization rate is still relatively low, namely less than 100%.
Kabupaten Sumbawa Barat海(KSB)被列入WPPNRI 573，包括Sawu海区域、印度洋水域、西帝汶海、爪哇南部水域和西努沙登加拉南部(KKP, 2014)。在WPPNRI 573的929,330吨潜在渔业资源中，底栖鱼类的潜力仅次于远洋鱼类，总产量为103,501吨。捕获量的增加超过可持续的潜在价值，将减少下一个周期的捕获量，甚至有可能导致渔业资源的灭绝。因此，必须通过安排与资源承载能力相匹配的捕捞努力来克服这一问题。本研究的目的是确定西松巴哇县底栖渔业的可持续潜力及其利用水平。在本研究的准备工作中使用的方法是实地调查和描述性方法。对获得的数据进行统计和描述分析，使用Schaefer剩余生产模型估计鱼类资源。结果表明，渔获量与渔获量之间的关系为线性方程y=8809-4.425x, R=0.024，说明渔具与渔获量之间不存在关系。渔获量受季节性和海洋条件等外部因素的影响。最佳努力值为每年19,489.91次，最大可持续捕获量为每年8,584,332公斤。去年的利用率值为0.01%，努力水平值为0.01%。利用率还比较低，即不到100%。

The Pangkal Babu Mangrove Forest has an important role in a fish habitat that is closely related to the livelihoods of fishermen so it has an overall economic relationship. This study aims to analyze the condition of mangrove forests, the triangulation relationship between mangrove forests and fish resources, and the community's economy as well as forms of local wisdom in protecting and preserving mangrove forests. This research was conducted in the Pangkal Babu Mangrove forest area, Tungkal Ilir District, West Tanjung Jabung Regency. The method in this study is a survey method. The sampling technique for the condition of the mangrove forest was using the Line Transect Plot method at 3 different stations. The data analyzed included the density of mangrove forests, fishery resources, the economy, and the local wisdom of the community. The results showed that at station I the condition of mangrove vegetation in Pangkal Babu was in moderate criteria with 1,467 trees/ha, station II was in very dense criteria with 3,367 trees/ha, and station III was in moderate criteria with 1,000 trees/ha. Fishery production for 5 years is 93,221 kg with many trips of 2,115 and a CPUE value of 44.13 kg/trip. Fishery production has exceeded the sustainable potential both biologically (MSY = 82,297 kg) and economically (MEY = 82,296 kg). The value of the coefficient of determination (R2) is 0.82 or 82%, which indicates that the fluctuation in fishery production is caused by the area of mangrove forests by 82%.

Turmeric (Curcuma longa) contains curcumin that can be used to improve the health as well as the immune system of the fish. The health and immune system condition of the fish can be predicted based on the hematology of the fish. A study that aims to understand the effects of turmeric addition in fish feed pellets on the hematology condition of common carp has been conducted from March to May 2022. The turmeric powder was mixed well with the feed pellets and the dosages of the turmeric powder were as follows: 0 (Control, no turmeric addition), P1 (0.5 g/kg), P2 (1 g/kg), and P3 (1.5 g/kg). The fish was reared in circular plastic containers (25 L), completed with an aerator and circulation pump) for 49 days, 15 fish/ container. During the research, the fish was fed 3 times/ day, at satiation. Samplings were conducted 2 times before the treatment was applied and by the end of the experiment (the 49th day). Results show that the addition of turmeric powder in the fish feed pellets clearly affects the hematological of the fish. Fish that was fed with turmeric-enriched pellets showed a higher percentage of lymphocyte and which means that the immunity of the fish is improved. The best treatment P3 showed 81.55% lymphocyte, 6.55% monocyte, 5.44% neutrophil, and 5.44% thrombocyte. Data obtained indicate that the fish fed with turmeric pellets perform better in hematological conditions than the fish with no turmeric-enriched pellets.

Red ginger is a natural ingredient that contains several antibacterial compounds such as essential oils, flavonoids, terpenoids, phenols, and zingiberene. This research was conducted from June to August 2021. The purpose of this study was to analyze the structure of the gill and liver tissue of jambal siam fish and to obtain the best dose of adding fermented red ginger to the feed before and after being challenged with Aeromonas hydrophila bacteria. The method used is an experimental method using a one-factor Completely Randomized Design (CRD) with five treatment levels and three replications, namely: Feeding without fermentation of red ginger and without being tested against A. hydrophila (Kn), Feeding without fermentation of red ginger and tested against A. hydrophila (Kp), Feeding with a dose of 150 mL/kg (P1), dose 175 mL/kg feed (P2), dose 200 mL/kg (P3). The results showed that the structure of the gill tissue of Jambal Siam fish showed damage such as hypertrophy, hyperplasia and bent lamellae. The best results were found in the P2 treatment, a dose of 175 mL/kg feed and tested against A.hydrophilla bacteria

A pump is a machine or device that raises liquid from a low surface to a higher surface or moves liquid from a low-pressure to a high-pressure area. A centrifugal pump is a machine or equipment used to provide energy to a fluid (liquid) based on the centrifugal force generated by a rotating impeller. So that the liquid can be moved or moved from one place to another. As it receives energy through the impeller, the fluid velocity will increase. This kinetic energy is then converted into compressive energy by the pump housing (casing) in the form of a spiral (volute) or a centrifugal pump or fixed blades (diffuser) surrounding the impeller so that the liquid exits the pump at a high speed. The maintenance method for the bilge pump auxiliary machine is carried out in 6 stages, namely, the first stage opening the filter box, the second stage removing the inner filter and filter box cover gasket, the third stage installing new anti-rust on the inside of the filter box cover, the fourth stage removing the box filter connecting faucet and the bilge pump pipeline, the fifth stage opens the connection of the pipe and the bilge pump, the sixth stage ensures that all components of the bilge pump are firmly installed and perform operational test

This study aimed to determine the effect of IB frequency using different simple aspirator on fertility, weight loss and hatchability of Payakumbuh duck (Anas platyrhynchos domestication) eggs. This study used 8 male and 20 female ducks, 90% egg production. In this study, all hatched the hatched eggs. This study used an experimental method with a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments consisted of: P1 is 1 x 2 days, P2 is 1 x 4 days, P3 is 1 x 6 days, P4 is 1 x 8 days; the parameters observed were fertility, weight loss and hatchability. The results of the analysis of variance showed that different AI frequencies had a significant effect (P < 0.05) on the fertility of hatching eggs, but had no significant effect (P > 0.05) on weight loss and hatchability. It can be concluded that P2 had a significant effect (P < 0.05) on fertility because fertile eggs were higher than other treatments. The characteristics of Payakumbuh ducks (Anas platyrhynchos domestication) spermatozoa are milky white and yellowish white, thick and watery consistency, specific odor, volume 0.24±0.05 ml, pH 7.37±0.51, mass movement +, ++ and +++, live percentage 79.06±3.68%, concentration 2.342 billion cells/ml, motility 75.00±7.56% and abnormality 12.06±0.82%. The results of the analysis of variance showed that different AI frequencies had a significant effect (P < 0.05) on the fertility of hatching eggs, but had no significant effect (P > 0.05) on weight loss and hatchability. The frequency of IB 1 x 4 days had the highest fertility rate, namely 67.72 ± 7.99%. A simple Aspirator can function properly with the need for repairs and upgrades in several parts of the tool such as current source, and fan capacity
