Abstract

Catfish (Clarias gariepinus) that are reared with probiotics as biofloc-forming agent is thought to increase the fish production. Applying swamp probiotics to the water media has never been studied to ensure the flocks' availability in the rearing media. This study aimed to determine the appropriate frequency of probiotics application collected from swamps for biofloc formation to improve the catfish production. This study used a completely randomized design with two treatments and three replications. The treatments were composed of different application frequency of swamp probiotics: (P1) once in 42 days of rearing and (P2) twice in 42 days of rearing. Data on flock volume, total bacterial colonies, absolute growth rate, feed efficiency, survival rate, and water quality were analyzed by T-test with a 95% confidence level. Meanwhile, the flock composition data were analyzed descriptively. The results showed that P2 obtained the best treatment with a floc volume of 68.33 10.41 mL/L, absolute length growth of 8.18 1.03 cm, absolute weight growth of 19.30 3.12 g, feed efficiency of 135.24 7.98%, survival rate of 89.33 6.21%, biomass production of 24639.50 1344.51 g, temperature of 28.85-29.59C, pH of 7.27-7.42, dissolved oxygen (DO) of 3.91-5.72 mg/L, ammonia of 0.45-1.15 mg/L, and total dissolved solids (TDS) of 717.33-885.50 mg/L. Therefore, swamp probiotics should be applied to catfish culture media twice for 42 days of rearing or once every 21 days.Keywords:BioflocCatfishProbiotics from swamp

Abstract

Photoperiod manipulation is one of the environmental management strategies that can influence the physiological condition of fish and support the success of aquaculture production. This study aimed to analyze the photoperiod preference of Indonesian leaffish (Pristolepis grooti) during the the post-transportation recovery period. The experiment used a Completely Randomized Design with three photoperiod treatments and three replications: (A) 24 hours light:0 hours dark (24L:0D), (B) 12 hours light:12 hours dark (12L:12D), and (C) 0 hours light:24 hours dark (0L:24D). The study was conducted at the Experimental Pond Instalation, Aquaculture Study Program, Universitas Sriwijaya. The results showed that treatment C (0L:24D) produced the lowest blood glucose level (93.33±2.08 mg dL⁻¹), the highest feed efficiency (1.67±0.05%), and relatively better absolute weight growth (0.05±0.01 g), with a survival rate reaching 93.33±11.55%. The oxygen consumption level indicated significant differences in metabolic activity among treatments, reflecting the best physiological condition of Indonesian leaffish under a 24-hour dark photoperiod (0.110±0.008 mg O2 g-1 h-1). Water quality values during the recovery period (temperature 28.1-30.2°C, pH 7.6-7.9, dissolved oxygen 2.9-3.1 mg L⁻¹, and ammonia 0.421-0,895 mg L⁻¹) were within the range that supports the survival of Indonesian leaffish. Treatment C (0L:24D) indicated the photoperiod preference of Indonesian leaffish during the post-transportation recovery period because it was able to maintain better physiological conditions, thereby supporting improved aquaculture performance during the subsequent culture period.
