Abstract

This research aims to determine the bioecological aspects of Betta fusca as teaching material for the Ecology Course. The research method used is an exploratory method. The research results showed that the length-weight relationship of Betta fusca fish showed negative allometric results, which means that the increase in length of the fish was not proportional to the increase in weight. The male to female sex ratio was found to be 1:2, indicating the predominance of females over males in the observed population. The physical and chemical parameters of the water observed showed variations, but everything was still in optimum conditions to support the life of Betta fusca. The conclusion of this research is that the bioecological conditions of Betta fusca in Labuhanbatu Raya Regency still support the sustainability of the population of this species.

Abstract

This study aims to examine the growth aspects of the fourfinger threadfin (Eleutheronema tetradactylum) caught in the waters of the Barumun River, Labuhanbatu Regency, North Sumatra. The research was conducted using a survey method, with fish samples collected from traditional fishermen in Telaga Suka Village using gill nets. The total length of the fish was measured using a ruler with an accuracy of 0.01 mm, and the weight was measured using a digital scale with an accuracy of 0.05 mg. Data analysis included size distribution based on Sturges’ rule and the length-weight relationship using a logarithmic approach. The results showed that the river-caught E. tetradactylum had a relatively even size class distribution ranging from 195–315 cm, while the bubble threadfin exhibited more varied sizes ranging from 138–168 cm. The length-weight relationship for both species indicated a negative allometric growth pattern, with b values of -3.9984 (river threadfin) and -5.5749 (bubble threadfin), indicating that length growth occurs faster than weight gain. In conclusion, E. tetradactylum in the Barumun River shows growth influenced by environmental factors, fishing gear, and anthropogenic activities. The species holds significant economic value for local communities, and thus its management should be directed toward sustainability.
