Oxidative stress on zebrafish (Danio rerio) has been evaluated for pH (four levels namely pH 4.5-5.5, 5.5-6.5, 7.5-8.5 and 8.5-9.5) and Dissolved Oxygen (DO 20-30%, 40-50% and 60-70%) in terms of oxygen saturation. Temporally, the exposure for pH levels were maintained from as 1h, 2h, 3h and 4h and for DO, it was (4h, 8h, 12h and 16h. The malondialdehyde (MDA) was used as biomarker of oxidative stress. It was observed that out of all tissues (skeletal muscle, liver, gill and brain) analyzed, zebrafish showed highest stress response in skeletal muscle against both environmental ambiances. In case of pH levels, significant increase in MDA level in skeletal muscle was recorded at pH 4.5-5.5, and the MDA level of skeletal muscle at 2h showed significant increase at this level of pH. Whereas, at DO 20-30% saturation level, skeletal muscle tissue significantly responded at this level of DO saturation and showed the maximum MDA level compared to the other tissues. On analysis for the duration of exposure, it was observed that skeletal muscle of zebrafish showed highest levels of MDA at DO 40-50% O2 saturation for 12h. In conclusion, it has become evident that zebrafish may undergo oxidative stress at pH 4.5-5.5 when exposed for 2hours, similarly, for DO it is 20-30% saturation for 12 hour exposure.

This review aims to investigate the impact of betel leaf extract administration in enhancing non-specific immunity in fish within the context of aquaculture. A literature review was conducted to evaluate previous studies, analyze the mechanisms of action of active compounds, and provide practical recommendations for field implementation. The review results indicate that betel leaf extract has antimicrobial potential that can inhibit the growth of bacteria, viruses, and parasitic agents causing diseases in cultured fish. The administration of this extract also stimulates non-specific immune responses, including increased production of immune cells such as macrophages and lymphocytes. The antioxidant effects of compounds in betel leaves provide protection against oxidative stress, enhancing fish resilience to unfavorable environmental conditions. Despite these positive findings, further research is needed to deeply understand the mechanisms of action of active compounds, taking into account environmental factors in betel leaf extract administration. Integration with other disease management strategies and strict monitoring of environmental safety are crucial aspects of practical implementation. In conclusion, the administration of betel leaf extract can be a promising alternative to enhance fish resistance to diseases in aquaculture. Administering betel leaf extract in feed and water can improve survival rates and egg hatching. Collaboration among researchers, farmers, and other stakeholders is necessary to optimize the practical application of these findings, with the goal of enhancing productivity and sustainability in the aquaculture sector as a whole.Top of Form

Cultivation of milkfish in Indonesia plays a central role in the fisheries sector, covering an expansive area of approximately 600,000 hectares and achieving a production of 621,393 tons in 2014. Milkfish-producing regions are distributed across various areas, including Sulawesi, Kalimantan, and Java, employing diverse cultivation technologies. Milkfish holds a crucial role in meeting food needs and contributing to the economic well-being of communities. Despite the predominantly traditional cultivation practices, yielding between 500 kg to 1 ton per hectare per year, there are also semi-intensive cultivation methods with yields reaching 3 tons per hectare per year. The high demand for milkfish seeds necessitates optimal water quality and strict supervision, serving as decisive factors in attaining optimal production outcomes. This research aims to acquire knowledge and skills related to milkfish breeding techniques, particularly at the Balai Besar Perikanan Budidaya Air Payau (BBPBAP) in Jepara. Data collection methods involve observation, active participation, and direct interviews. The results of this study indicate that the management of feed, broodstock maintenance, and feed management in milkfish breeding at BBPBAP Jepara are well-executed, supporting the success of milkfish breeding. The implications of this research can contribute positively to the development of milkfish cultivation techniques, focusing on milkfish breeding to achieve optimal production outcomes.

The increase in vaname production is carried out to meet market demand which continues to increase from year to year, so that various strategies are carried out in vaname cultivation. Besides of feed quality and disease prevention, water quality management is an effort to regulate and manipulate environmental conditions so that optimal range can supports shrimp growth, until good shrimp quality is obtained. Location of the activity at PT Bumi Harapan Jaya where has produced a lot of shrimp with the best quality, so it is necessary to know how water quality management is applied there. The method is carried out descriptively, namely describing what is done according to conditions in the field. The results of activities in managing water quality are starting from the preparation of ponds, seeds and good water sources. Water quality management during vaname shrimp rearing activities applies measurements of physical, chemical and biological parameters, where physical parameters such as temperature and brightness are maintained in the range of 27-30°C and 30-45 cm. In addition, the pH remains in the normal range of 7.7-8 and salinity 30-34 ppt. Carrying out regular water quality checks is the key to good water quality management, in addition to that, regular siphoning is also necessary to avoid high ammonia content in the culture water.

Koi fish is one type of freshwater fish that is classified as an ornamental freshwater fish that has economic value in the national and international markets. Efforts to develop koi fish cultivation cannot be separated from the breeding stage such as enlargement and nursery activities. One of the koi fish cultivation places in West Lombok Regency is at the Batu Kumbung Lingsar Fish Seed Center, so it is necessary to know what nursery techniques are applied there considering its good production. The activity was carried out for approximately 30 days at the Batu Kumbung Lingsar using a descriptive method. The results of the activities obtained were that in the koi fish nursery technique at the Batu Kumbung Lingsar Fish Seed Center, it started from pond preparation (drying, fertilization, liming, filling with water), parent selection, spawning, nursery and feeding. The pond drying is done for 2 days, liming, fertilization, and filling with water are done for 1 day, the weight of the parent that is ready to spawn is 1.5 kg for the male parent while for the female parent 4 kg, the ratio of the parent used is 2:1 where 6 male and 3 female broodstocks, the nursery is done at the age of 2 days with the results of the offspring spread in the nursery as many as 5000 larvae, and the feeding technique uses the ad satiation method.
