Snakehead fish (Channa striata) is an economically important fish. In order to meet market needs, the current supply is more dependent on catches in public waters than on cultivation. One reason is the lack of seed production from hatcheries. The purpose of this study was to analyze the effect of using...

Extension activities regarding independent feed production are certainly very much need-ed by aquaculture business actors because feed is one of the important factors in support-ing the development of a shrimp farming business. This study aims to improve the knowledge, attitudes and skills of the main...

The Chaetoceros is a genus of microalgae that belongs to the diatom group with the class of Bacillariophyceae. These microalgae are often found in Indonesia marine waters. Chaetoceros calcitrans is a species of microalgae that is widely used as natural feed in the fisheries sector because it has a high...

Fish living in aquatic ecosystems constantly encounter spatial and temporal changes in water temperature that shape their physiology and survival. Such thermal variation also modulates the immune response of fish against bacterial infection. Temperature shifts influence bacterial morphology, metabolism,...

The intensification of fish farming in Indonesia is at high risk of disease outbreaks, especially Aeromonas hydrophila bacterial infection that causes motile aeromonads septicemia (MAS). Vaccines are an essential alternative to disease control compared to chemicals or antibiotics. This study aims to...

The cultivation of Litopenaeus vannamei shrimp is closely linked to the aquatic ecosystem influenced by various factors, with the shrimp pond habitat playing a central role in determining aquaculture success. Shrimp farming performance is commonly assessed by the feed conversion ratio (FCR) and survival...

Alginate is widely used for encapsulation material in the development of fish drugs enrichment. In this study, alginate was developed to construct granules containing fish vaccines. The preparation of granules using alginate with food and pharmaceutical grade was compared to obtain the best shape. The...

Coastal ecosystems such as mangroves and coral reefs support marine biodiversity and stability, with microalgae as primary producers and environmental sentinels. We present the first comparative assessment of microalgal diversity and environmental drivers across adjacent mangrove and reef habitats in...

The Merangin Geopark area in Jambi features a rocky river with a fast current, creating a unique habitat that promotes ecomorphological adaptations among the resident fish species. The objectives of this research are: (1) to document the fish fauna of the Merangin Geopark, (2) to determine the IUCN conservation...

The construction of the Jambi–Riau Toll Road, which traverses several major river systems in central Sumatra, raises ecological concerns regarding the potential impact on freshwater fish biodiversity. This study was conducted to assess the baseline diversity and ecological condition of fish fauna in...

Cengklik and Mulur reservoirs are two important inland water bodies in Surakarta regency, serving as water sources and habitats for diverse fish communities. Understanding the structure and composition of the fish communities is vital for biodiversity monitoring and resource management. This study aims...

Fishes from the Lethrinidae family are demersal fish that have important economic value and are widely found in tropical waters, including in Maluku waters. The propose of this study is to inventory fishes from the Lethrinidae Family that are sold at Mardika Market, Ambon, Indonesia. This research was...

Socah Village has a huge potential of fisheries resources, one of which is mullet (Family: Mugilidae). Research on the biological aspect of mullets in Socah Waters has not been carried out, so it is necessary to research the frequency of length and weight, the length at first capture (Lc=Lc50%), and...

This research assessed the sustainability of glass eel management in the Cimandiri Estuary and River. The evaluation utilized the framework of the seven domains of ecosystem-based fisheries management specific to inland fisheries. The study commenced in December 2024 and concluded in March 2025. Primary...

Tamblingan Lake is the smallest lake in Bali and plays a vital role in the surrounding environment. The fish community in Tamblingan Lake includes the bonylip barb (Osteochilus vittatus), spotted barb (Barbodes binotatus), silver rasbora (Rasbora argyrotaenia), convict cichlid (Amatitlania nigrofasciata),...

In order to preserve environmental equilibrium and sustain the way of life for coastal populations, mangroves are an extremely vital ecosystem. The purpose of this study was to assess the structure and health of the mangrove community in Lembung Paseser Village, Sepulu District, Bangkalan Regency. The...

Small pelagic fisheries are shaped by fleet characteristics, fishing gear, operational tactics, and management strategies. However, critical gaps persist in understanding technical aspects such as vessel size, engine power, gear types, fishing duration, and crew composition. This desk study focuses on...

Flying fish (Exocoetidae) represent an important marine resource in the Aru Islands, Eastern Indonesia, where their eggs have long been harvested using traditional bale-bale gear. However, recent increases in exploitation by andon fishers from Sulawesi have placed growing ecological strain on the resource...

Mineral-rich sea salt is considered a healthier alternative to conventional salt due to its lower sodium content and retention of essential minerals. However, its quality can be influenced by environmental conditions and storage duration. This study aimed to evaluate the quality of mineral-rich sea salt...

The skin of black snapper (Lutjanus griseus) is a promising, environmentally sustainable, and economically viable alternative source of collagen. This study aimed to examine the effects of acetic acid concentration and hydroextraction duration on the quality characteristics of the extracted collagen....
