Global warming poses a critical challenge worldwide, driven by high levels of carbon emissions. This study aims to evaluate the carbon sequestration potential of Kappaphycus alvarezii seaweed cultivated using the longline system in Bondo waters, Mlonggo District, Jepara Regency. The research involves measuring carbon absorption, analyzing carbon content, estimating the total carbon sequestration …

Mozambique tilapia (Oreochromis mossambicus) is an important aquaculture commodity in Indonesia; however, its productivity can be constrained by disease outbreaks, including Aeromonas hydrophila infection. The use of natural feed additives containing nutritional and bioactive compounds is a promising strategy to improve fish growth and health. This study aimed to evaluate the effectiveness of oct…

A common problem faced by betta fish breeders during the hatchery stage is the low survival rate of fry, as they are highly susceptible to changes in water quality and disease. Therefore, fry management is necessary to increase survival rates by using natural ingredients that are environmentally friendly and do not cause resistance. Ketapang leaves (Terminalia catappa) and betel leaves (Piper bet…

Small-scale fisheries in coastal areas utilize various fishing gears, including bottom gillnet, which can catch fish species with different trophic levels. Fishing activities may influence the trophic structure of fish communities and the vulnerability of species to exploitation. This study aimed to analyze the trophic structure, vulnerability level, conservation status based on the IUCN Red List…

Polystyrene microplastics (PS) in aquaculture systems may impair shrimp behaviour and survival, yet experimental evidence directly linking exposure intensity with easily observable behavioural indicators remains limited. This study evaluated the effects of sublethal PS exposure on swimming behaviour and survival of whiteleg shrimp during a 45-day rearing period. A completely randomized design was…

Argulus sp. is one of the ectoparasites that commonly infects common carp (Cyprinus common carpio) and can reduce fish health and productivity. One environmentally friendly control method is the use of natural ingredients such as noni fruit (Morinda citrofolia) which contains bioactive compounds that have antiparasitic properties. This study aimed to analyze the effect of noni fruit extract on th…

Giant gourami (Osphronemus gouramy) is a freshwater fishery commodity with high economic value and is widely cultivated in Banyumas Regency. However, the emergence of diseases caused by pathogenic bacteria often becomes an obstacle in cultivation activities because it can reduce the survival rate and productivity of fish. This study aims to identify the types of pathogenic bacteria found in goura…

Fungal infections in shrimp are one of the main challenges in shrimp farming activities that have the potential to reduce productivity levels and crop quality. Fungi are known as opportunistic microorganisms that can cause serious problems, especially when pond environmental conditions are not supportive. Fungal attacks generally occur when shrimp experience physiological stress due to temperatur…

Tilapia is the most widely cultivated fish in Banyumas which is susceptible to bacterial diseases caused by the increasing number of disease cases in tilapia (Oreochromis niloticus) due to high cultivation intensification. One of the diseases that often attacks is streptococcosis caused by the bacteria Streptococcus sp., which can cause mass mortality and major economic losses for farmers. The pu…

Fish farming has increased significantly compared to capture fisheries due to overfishing and the excessive exploitation of wild fish resources. However, the intensification of aquaculture systems is often followed by the emergence of various diseases, including ectoparasite infestations. Ectoparasites are important pathogens that can reduce fish productivity and health status. Their presence may…

The development of stable and palatable artificial feed remains a major challenge in the culture of Asian swamp eel (Monopterus albus), mainly due to the continued reliance on natural feeds such as earthworms. This study evaluated the effects of different binder types and concentrations on feed stability and eel feeding responses using pasta feed formulations combining commercial pellets and eart…

Motile Aeromonas Septicemia (MAS) is one of the bacterial diseases that attacks and causes mass death of nile tilapia. Disease control in fish farming using synthetic antibiotics has caused problems in aquaculture, such as bacterial resistance to antibiotics, drug residues in fish, and water pollution. Therefore, alternative measures to control MAS that are safe and environmentally friendly, such…

Pacific oysters (Crassostrea gigas) are one of the major aquaculture commodities that contribute greatly to the Japanese fishing industry. This study aims to describe the oyster farming management system based on field research experience in Hyogo Prefecture, Japan. The method used was participatory observation for eight months, covering all stages of aquaculture from seed collection to post-harv…

Choux pastry is a baked product that generally has low fiber content due to its primary ingredient, wheat flour, which contains minimal dietary fiber. Incorporating alternative ingredients rich in fiber can enhance its nutritional value. One such ingredient is Eucheuma cottonii seaweed flour, which is high in dietary fiber and offers potential for innovation in the utilization of fishery-based pr…

Cytochrome P450 (CYP450) enzymes are vital enzymes in the metabolic processes of fish, playing a crucial role in the detoxification of xenobiotics and the regulation of endogenous compounds. The biotransformation of pollutants, including pesticides, medicines, and polycyclic aromatic hydrocarbons (PAHs), which build up in aquatic environments, is facilitated by these enzymes, especially those in …

Mud crab (Scylla serrata) is a fishery commodity that has high economic value and has a wide salinity tolerance so that its growth can be developed. The growth of mud crabs can be influenced by genetic traits such as moulting. In cultivation activities there are methods that can accelerate the moulting process such as environmental engineering (increasing and decreasing the salinity of the mainte…

Aquatic animal health management is a critical aspect of maintaining the sustainability and productivity of aquaculture systems. The increasing complexity of aquatic ecosystems and the challenges posed by the emerging diseases necessitate innovative approaches for effective health management. Molecular medicine necessitates the integration and analysis of genetic, molecular, cellular, and clinica…

The use of herbal plants in aquaculture has emerged as a sustainable and eco-friendly approach to improving fish health, enhancing immunity, and boosting growth performance. Various herbs are rich in bioactive compounds that stimulate non-specific defense mechanisms, enhance phagocytic activity, and reduce oxidative stress through their antioxidant properties. These immunostimulatory effects impr…

One material that can be used to improve feed quality is octopus ink. Octopus ink can serve as an alternative nutrient source to optimize catfish growth. Ink produced by cephalopods such as squid, octopus, and cuttlefish contains various components, including fat, protein, ash, and carbohydrates. The aim of this research is to determine the effect of administering octopus ink extract (Octopus sp.…
