The restoration of water quality needs to be monitored on the rivers in Indonesia. Land occupation and land conversion are the main problems that have an impact on the handling of water quality in the Muara Gembong area. The research location is located in Muara Gembong District, Bekasi Regency, West Java. Water quality testing in this study was carried out directly in the field using in situ digital measuring instruments including pH, air temperature, DO, TDS, Phosphate, Brightness and Salinity. Meanwhile, the TSS and BOD parameters were tested in the laboratory at the Secretariat of the Indonesian Biodiversity Conservation Unit (IBCU). The results of the Pollution Index showed that the research location was divided into 2 groups, namely moderate pollution Beting Outfall, Bungin Outfall and Upstream), light pollution (Middle Stream, Bendera Outfall, Outfall Bloom and Outfall Herons). The results of PCA analysis with a variance value of 40.8% showed that the location of the study was holistic by BOD value, phosphate content and salinity as environmental parameters that determined environmental conditions.

Larvae health management is a key factor in the hatchery of humpback grouper (Cromileptes altivelis) to prevent mass larval deaths and cause financial losses. Management of humpback grouper larvae health includes larval rearing, larval feed management and larval disease control. The primary data collection method was carried out in 3 ways, namely observation, active participation and interviews. Secondary data retrieval by studying literature from various related sources. The humpback grouper larvae were reared in the hatchery to control the temperature and condition of the larvae. Larval ponds are sterilized with 3-5 ppm chlorine in the morning and rinsed thoroughly so that no chlorine remains. Larvae were reared from the age of 1 day to 45 days. Feeding the larvae was started when the larvae were 2 days old with Nannochloropsis occulata. Rotifers were given when the larvae were 2-3 days old with a density of 5 individuals/ml. Artemia was given when the larvae were 20 days old until the age of 40 days. Pellets are given when the larvae are 8-10 days old with a pellet size of level 1. The pellet size continues to increase according to the larva's mouth opening. The disease that often attacks larvae is Viral Nervous Necrosis (VNN). The characteristics of larvae infected with VNN are reduced appetite, weak movement, larvae float on the surface and lie on the bottom of the pond. VNN attacks can only be overcome by prevention. The bacteria that often attack the larvae are Vibrio alginolyticus. Vibrio alginolyticus can be treated with antibiotics or non-antibiotics. The use of antibiotics is not recommended because they have negative side effects, so you can use other alternative medicines derived from herbal plants (phytopharmaceuticals).

The needed for carp in Jayapura City was greatly increasing along with the high growth and increase of population in Jayapura City. Cultivation of carp (Cyprinus carpio) can be done intensively and semi-intensively by taking into account the economic value. However, from cultivation activities, the problems that were often faced in cultivation activities were the attack of dangerous types of pathogens such as parasites. Parasite was a fish disease that occurs more frequently. Parasites were organisms that live on the body of other organisms and generally have a negative effect on their host. This study aimed to identify and the prevalence of ectoparasites to determine the type and level of ectoparasite attack on carp (C. carpio) seeds and to reduce the impact of ectoparasites which was feared to reduce the amount of carp production from cultivation. The method used was a direct survey to the Local Fish Seed Center and fish farmers in the Koya Barat area. The fish used were carp in the seed phase where the fish's immune system was still weak, making it more susceptible to contracting parasites. This study showed that there were 4 types of parasites found during the study that infected carp seeds, namely Dactylogyrus sp, Gyrodactylus sp, Trichodina sp, and Lernea sp. The average prevalence rate of Dactylogyrus sp. at stations I, II, III, and IV was 25%, Gyrodactylus sp. 8.3%, Trichodina sp. 8.3% and Lernea sp. 5% with the lowest prevalence rate.

Vaname shrimp (Litopenaeus vannamei) is one of the commodities that is very promising for aquaculture and is a prima donna because of the high international market demand so that vaname shrimp production needs to be increased. Increasing shrimp production can be done with a high stocking density system. However, one of the drawbacks of this system is that it can reduce water quality because this system requires high feeding. Declining water quality will cause stress to the shrimps and cause diseases that cause failure in shrimp enlargement, it is necessary to manage water quality properly and appropriately. The main parameters observed in this study were stocking density, feed management and water quality monitoring. Water quality during the observation is still in the normal range of brightness, 25-90 cm, temperature ranges between 27-31.8.0C, pH between 67.1-8.7, salinity 19-31 ppt, dissolved oxygen between> 4.03 -5.60 mg / l, alkalinity ranges from 74-154 mg / l, TOM ranges from 24.8-90.0 mg / l, ammonium ranges from 0.5-5 mg / l, nitrites range between 0.5 -18 mg / l, and phosphate ranges from 0.25-18 mg / l.

The most important factor in speeding up fish depends on the food given. The feed given was in the form of artificial feed (pellets) because of the practicality of its availability. However, commercially made feed was of course more expensive, and can pollute the air compared to natural feed which was easy and can be in the surrounding environment. For this reason, it was necessary to look for natural feed as an effective and efficient alternative feed to ripen the gonads of male and female swordtail. The research used a completely randomized design with 4 treatments and 3 repetitions and arranged randomly. Treatment by giving different natural food to the broodstock swordtail: treatment A (commercial pellets), B (Daphnia/Moina), C (blood worms) and D (mosquito larvae feed). Each broodstock treatment used was 27 females and 9 males (ratio 1: 3). The results of water quality measurements of all treatments with an average DO 4 mg/L, temperature 26 to 27oC, pH 7-8 and 30 mg/L hardness, thus showing the water quality during the research, the water condition was suitable for the maintenance of broodstock of swordtail, so that it supported growth. and breed of swordtail to produce tillers. The results showed that the highest average birth rate of swordtail broodstock produced in treatment D were 141 fish followed by treatment B 125 fish, then treatment C of 117 fish. and the lowest was in treatment A with a birth rate of 102 fish.

The results showed that the highest average birth rate of swordtail broodstock produced in treatment D were 141 fish followed by treatment B 125 fish, then treatment C of 117 fish. and the lowest was in treatment A with a birth rate of 102 fish.","PeriodicalId":250719,"journal":{"name":"Journal of Aquaculture Development and Environment","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126524413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Tilapia is one of the consumption fish commodities that was very popular with the public. The development of tilapia aquaculture was growing rapidly, especially saline tilapia. The high potential of saline tilapia development causes the demand for fingerlings to increase. This research aimed to determine the best dose of salinity increase in the effort to adapt freshwater tilapia to saline tilapia. In addition, it also observed survival, growth and feed efficiency. The method used was experimental method with completely randomized design and data were analyzed using SPSS16 and Tukey's test. The research treatments included the levels of addition of salinity by 1 ‰/day, 2 ‰/day, 3/day and 4 ‰/day. The difference in salinity had a significant effect on Survival Rate (SR), Growth Rate (GR), Specific Growth Rate (SGR), Feed Conversion Ratio (FCR) and Feed Utilization Efficiency (FUE). The best treatment in this research was the addition of salinity of 1 ‰/day with SR of 96%, GR of 35.1 g / t, SGR 1.22% w / day, FCR of 1.04 and FUE of 96%.
罗非鱼是一种非常受大众欢迎的消费鱼类商品。罗非鱼养殖业发展迅速，尤其是咸味罗非鱼。咸水罗非鱼的高发展潜力导致对鱼种的需求增加。本研究旨在确定使淡水罗非鱼适应咸水罗非鱼的最佳盐度增加剂量。此外，还观察了成活率、生长和饲料效率。采用完全随机设计的实验方法，采用SPSS16和Tukey检验对数据进行分析。研究处理包括1‰/d、2‰/d、3‰/d和4‰/d的盐度添加水平。盐度差异对成活率(SR)、生长率(GR)、特定生长率(SGR)、饲料转化率(FCR)和饲料利用效率(FUE)均有显著影响。本试验的最佳处理为盐度为1‰/d, SR为96%，GR为35.1 g / t, SGR为1.22% w /d, FCR为1.04,FUE为96%。
