A sustainable aquaculture model in Indonesia: multi-biotechnical approach in Clarias farming

Abstract

Clarias catfish is the second rank of Indonesian commodity after tilapia in the production of freshwater aquaculture. It is due to the biotechnical innovations in aquaculture for breeding and grow-out, as well as selective breeding of superior fish. Nowadays, Clarias farming is a promising business because of a large market available in line with food security, fish farmers’ welfare, and sustainable aquaculture. The objectives of this paper are to review the latest status of Clarias catfish, improvement technologies used, challenges, constraints, and strategies to increase and maintain national production. In terms of seedlings production, the existing technology is relatively well-established with available segmentation in fingerling production. As for grow-out, many innovations such as the use of probiotics, biofloc, aquaponics, RAS, and IMTA provide opportunities for various business scales. The availability of technology based on a biotechnical approach enables to improve and maintain the sustainability of national Clarias production. The progress of Clarias farming in the last decade should be suggested as a model for other potential species. It is recommended that genetically improved Clarias by utilizing the potential of local catfish should be applied to produce specific advantages for development in certain areas and to increase business productivity.

Sustainable Development: The Case for Aquatic Biodiversity in Indonesia’s Peatland Areas

“…Ponds must be prepared in numerous phases before they can be used for peatland fish farming. In the future, it is intended that fisheries development for community empowerment and welfare, such as catfish and snakehead fish farming in Indonesia, will be adopted [35,36].…”

“…For example, in order to improve the identification of indigenous fish, DNA barcoding must be implemented [43]. This has been done in a number of economically important freshwater fish, including the snakehead C. striata [32,35], Asian redtail catfish Hemibagrus nemurus [44], striped catfish Pangasius hypophthalmus [45], and African catfish Clarias batrachus [44].…”

Chloroform Fraction from Methanol Extract of Starfish Acanthaster planci Stimulates Catfish (Clarias sp.) Macrophage Immunomodulatory Activity

“…Catfish (Clarias sp.) is Indonesia's most important freshwater commodity (Gustiano et al, 2021). Some cultivators are willing to increase production yield by implementing an intensive cultivation system and rearing fish in a small area with a high stocking density.…”

“…Clarias sp. culture has some deserving perspectives in Indonesia (Diatin et al, 2021;Gustiano et al, 2021;Henriksson et al, 2017). Clarias sp.…”

Biological Activity of Catfish (Clarias gariepinus) Mucus Gel on the Wistar Rats (Rattus norvegicus) Wound Healing Process

“…1 It is a preferred consumption freshwater fish, which has several advantages, including high nutritional content, fast growth, being easy to breed, being easy to adapt to all water conditions, being easy to cultivate, and being easy to market with relatively low capital requirements and therefore having a relatively affordable price. 2 According to Indonesia Central Bureau of Statistics data, national production of Clarias gariepinus catfish commodities has increased rapidly, reaching over 1 million tons with a value of more than 17 billion IDR. 3 In 2017, production increased by 131 percent from the previous year.…”
