Abstract

Environmental factors play an important role in the growth and survival of fish, both directly and indirectly. This role is not limited to determining the success of fish growth in terms of length and weight; fish behavior, feeding patterns, and metabolism are also affected. Photoperiod itself is defined as the length of time of light and dark exposure. This study aims to evaluate the effect of photoperiodism on the growth rate and physiological response of red tilapia (Oreochromis niloticus). The study was conducted in Gandus District, Palembang City. Data and analysis were performed using a completely randomized design (CRD) with several parameters such as growth rate, weight gain, survival rate, and behavior of red tilapia observed qualitatively in response to treatment with varying light exposure times. The treatments given were 3 variations of light and dark exposure and 5 repetitions with variations P1: 20 hours of light: 4 hours of dark (20T; 4G) P2: 16 hours of light: 8 hours of dark (16T; 8G), and P3: 12 hours light : 12 hours dark (12T; 12G). The analysis results showed that red tilapia had a positive growth response, characterized by an increase in fish length and weight, caused by increased metabolism due to an increase in feed consumption rate. Fish behavior changed compared to the control group due to physiological stress caused by prolonged exposure to light.

Abstract

This community service initiative, conducted under the Community-Based Empowerment Scheme, aims to enhance the economic independence of the Burai Village Youth Organization (Karang Taruna) through the implementation of biofloc technology in catfish cultivation and the utilization of maggots (Black Soldier Fly larvae) as an alternative feed source. The program was carried out from March to November 2025, comprising several stages: initial exploration, Focus Group Discussions (FGDs), outreach, technical training, and field practice. The training focused on three key aspects: (1) biofloc-based catfish farming, (2) maggot cultivation as a high-protein feed, and (3) basic marketing and bookkeeping strategies. The outcomes showed a significant improvement in the capacity of village youth to manage productive, fisheries-based enterprises. However, challenges remained, including fish mortality rates of up to 30% due to unstable water quality and maggot mortality caused by high environmental temperatures. Corrective measures were implemented through regular water quality monitoring, improved feed management, and better control of maggot rearing conditions. Overall, this program successfully strengthened the technical and managerial skills of Karang Taruna members, fostered an entrepreneurial mindset, and opened up sustainable business opportunities utilizing local resources.
