Abstract

This study examines the hatching and rearing process of catfish (Clarias gariepinus) larvae at the Fish Seed Center (BBI) in Lingsar, West Lombok Regency. Pond preparation, parent selection, spawning, larval rearing, feeding, and water quality monitoring are the main focuses. The research method used is observation, interviews, and literature review. The results indicate that pond preparation includes cleaning, liming, fertilization, and water filling, while parent selection is based on physical criteria and egg maturity. Spawning is done naturally with water quality monitoring being important for egg survival. Larval rearing includes feeding and growth measurement done on a scheduled basis. Water quality is monitored periodically to ensure optimal conditions. Although the percentage of egg hatching is relatively low, catfish larval rearing shows good growth with the appropriate approach.

Abstract

The development of Ekas Bay as a center for integrated aquaculture activities, particularly through the Floating Net Cage (FNC) system, can impact phytoplankton abundance and water fertility. Phytoplankton, a type of plankton capable of photosynthesis, acts as a primary producer and serves as a key food source for fish and lobsters. The presence of phytoplankton is closely related to the fertility levels of waters designated for marine aquaculture. This study aims to determine the composition and abundance of phytoplankton in the waters of Ekas Bay. The research employed purposive sampling, collecting phytoplankton samples from five predetermined stations: three points near FNCs and two points distant from the FNC area. The results indicate that the plankton abundance in the waters of Ekas Bay is categorized as mesotrophic. The highest phytoplankton abundance was recorded at Station V with 9,523 cells/L, while the lowest was at Station II with 2,150 cells/L. Based on station characteristics, Station V is the farthest point from FNCs, whereas Station II contains a high concentration of FNCs. The community structure, as indicated by the H’, E, and D values, suggests that the waters of Ekas Bay remain in a stable condition. Phytoplankton from the class Bacillariophyta was the most commonly found, although no specific genus was dominant.

Abstract

From several decades ago until today, coffee consumption has been a cultural norm. Coffee pulp (CP) is a byproduct of the initial separation of husks or seeds from coffee fruits. The increase in coffee production will lead to an increase in CP residues and refuse, which, if left unchecked, will result in environmental issues. Several previous studies have attempted to address this waste by focusing on organic fertilizer products, enhancing soil conditions, biological control, animal feed, and human sustenance. However, only a small number of researchers have conducted studies utilizing CP, and most of them have not been successful in incorporating this raw material into fish nutrition. Consequently, the purpose of this review is to characterize the potential of CP in the field of aquaculture so that additional research can be conducted using this raw material.

Abstract

The global demand for coffee is increasing each year, and as a result, the number of debris that will be generated will also be as large as coffee husks. Therefore, efforts must be made to employ coffee husks. In the disciplines of biogas, fertilizers, bioethanol, biofuels, enzymes, and bioactive compounds, efforts have been made to utilize coffee husks. However, only two researchers have investigated the use of coffee husks as an alternative raw material and preservative for tilapia flesh in the fisheries industry. This article explains the prospective use of coffee husks in the fisheries sector, particularly in fish farming and processing.

Abstract

The improvement of fish immunity is a critical factor in successful aquaculture. In recent years, the use of garlic (Allium sativum) as an immunostimulant has attracted researchers and farmers' interest in enhancing fish's health and disease resistance. This abstract discusses an overview of the use of garlic as an immunostimulant in aquaculture. Garlic is widely known for its antimicrobial, antioxidant, and immunostimulant properties. Several studies have evaluated the effects of garlic supplementation on various species of cultured fish. The results have shown that the administration of garlic in fish feed can enhance immune responses, such as increased immune enzyme activity and antibody production. Furthermore, active components in garlic, such as allicin and diallyl sulfide, have been proven effective against fish pathogens such as bacteria, viruses, and parasites. However, garlic as an immunostimulant in aquaculture still requires further research. Factors such as the appropriate dosage, interactions with farming conditions, and a deeper understanding of the underlying mechanisms must be considered. To optimise the use of garlic, further research is required to explore optimal dosages, interactions with environmental factors, and a better understanding of its effects on fish immune responses. In conclusion, garlic as an immunostimulant in aquaculture shows promising potential. The oral administration of garlic extract through the fish feed is capable of preventing infections by Aeromonas sp. and Aeromonas hydrophila in fish species such as Tawes, Catfish, Dumbo catfish, and Nile tilapia, while also enhancing non-specific immunity, such as increased total hematocrit, total haemoglobin, total erythrocytes, and phagocytic activity.

Abstract

The use of immunostimulants from papaya leaves as a treatment strategy for fish diseases has gained attention in the field of aquaculture. Initial studies have shown that the active compounds in papaya leaves have the potential as immunostimulants to enhance the fish immune system and combat disease infections. Previous studies have revealed that the administration of papaya leaf extracts in fish feed can stimulate immune responses, including activating immune cells such as macrophages and increasing antibody production. The compounds in papaya leaves also exhibit antimicrobial effects that help fight against pathogens causing diseases in fish. Although research findings indicate the potential use of papaya leaf immunostimulants, further studies are needed to understand their mechanisms of action comprehensively. Factors such as effective dosage, optimal administration methods, and their effects on various diseases must be clarified. Safety aspects should also be considered, including potential side effects and residues in fish intended for human consumption. Consideration should also be given to sustainable fish farming practices and the potential environmental impacts of the widespread use of papaya leaf immunostimulants. In conclusion, using immunostimulants from papaya leaves to treat fish diseases shows promising potential. However, further research is required to understand their effects thoroughly, determine the appropriate dosage, evaluate the safety, and consider sustainable aquaculture aspects before their use can be widely recommended in aquaculture practices.

Abstract

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.

Abstract

Mud crab (Scylla spp.) aquaculture holds significant potential in supporting food security, economic growth, and ecological balance. This study aims to summarize various findings related to critical factors in mud crab farming, such as feed types, rearing systems, and stocking density, and their impact on productivity, feed conversion ratio (FCR), and economic profitability. The review highlights that trash fish feed at 15% of body weight yields optimal growth and feed efficiency due to its high protein content. Feed diversification, including stingray and janitor fish, offers promising results with reduced costs. Various rearing systems are employed, ranging from cages and earthen ponds to advanced technologies such as Recirculating Aquaculture Systems (RAS). Small bamboo floating cages demonstrate superior outcomes in growth and survival rates (SR). Mangrove habitats significantly enhance crab growth, while silvofishery systems provide a sustainable farming alternative. Optimal stocking density, such as 4 crabs/m², balances growth and production. Additionally, Scylla serrata exhibits the best growth rate compared to other species, particularly males. Innovations like soft-shell farming technology add economic value to the product. Overall, the success of mud crab aquaculture depends on the optimal combination of feed, rearing systems, and environmental management. This review offers strategic insights for developing efficient, sustainable, and economically viable crab farming practices.
