Abstract

apiat (Barbonymus schwanefeldii) is one of the economically important freshwater fish found in the Muaro Pijoan River, Jambi. Intensive fishing pressure and water quality degradation due to anthropogenic activities pose threats to the sustainability of this fish population. This study aims to examine the size distribution and growth patterns of kapiat in the Muaro Pijoan River as a scientific basis for development of freshwater aquaculture. Sampling was conducted in October 2025 using traps and gillnets. A total of 83 kapiat were collected, consisting of 51 males and 32 females. Male fish had a total length range of 110–160 mm with a weight range of 20–55 g, while female fish had a total length range of 120–166 mm with a weight range of 21–71 g. The size distribution of male fish was dominated by the 134–141 mm size class (25 individuals), while female fish were dominated by the 156–164 mm size class (13 individuals). Length-weight relationship analysis showed that male fish exhibited a negative allometric growth pattern (b = 2.6399; R² = 0.7313), indicating that length growth was faster than weight gain. In contrast, female fish exhibited a positive allometric growth pattern (b = 3.4445; R² = 0.8998), indicating that weight gain was faster than length growth due to the gonadal maturation process. The relatively smaller size distribution compared to other populations suggests environmental influence on growth performance. These results provide baseline information for domestication strategies, broodstock selection, and feeding management in freshwater aquaculture systems

Abstract

Catfish farming (Clarias gariepinus) is one of the rapidly growing aquaculture sectors in Indonesia. However, the main challenges frequently encountered are limited cultivation land and declining water quality due to the accumulation of metabolic waste, particularly ammonia. The Recirculating Aquaculture System (RAS) offers a solution by reusing culture water, assisted by mechanical, chemical, and biological filtration processes. RAS aims to minimize external water exchange while maintaining water quality at levels suitable for fish survival and growth. This article aims to review the concepts and benefits of recirculating systems in catfish culture, based on a literature review of scientific journals and related books, using a descriptive-exploratory approach. The review indicates that RAS provides numerous benefits, including improved water-use efficiency, enhanced water quality, reduced ammonia concentration, and increased stocking density and productivity in catfish culture. The role of filtration units and microorganisms is crucial in maintaining system stability, particularly in the decomposition of organic waste and toxic compound
