Abstract

The study investigated the effects of different salinity levels in a biofloc system on the growth and survival of climbing perch (Anabas testudineus). It employed a completely randomized design with five treatments, each replicated three times. The treatments consisted of maintaining climbing perch in the biofloc system at various salinity levels: 0 g L⁻¹ (P0), 2 g L⁻¹ (P1), 4 g L⁻¹ (P2), 6 g L⁻¹ (P3), and 8 g L⁻¹ (P4). The results demonstrated varying impacts across the treatments. The most favorable outcomes were recorded in the group maintained in the biofloc system with molasses and a salinity of 6g L⁻¹ (P3). This treatment yielded an absolute length growth of 1.40cm, weight growth of 1.78g, a survival rate of 92.52%, feed efficiency of 69.02%, and a floc volume of 10.6mL L⁻¹. Throughout the rearing process, total suspended solids (TSS) ranged from 91 to 145mg L⁻¹, total dissolved solids (TDS) were at 7984.81mg L⁻¹, pH was 7.60, dissolved oxygen was 4.81mg L⁻¹, ammonia levels ranged from 0.020 to 0.077mg L⁻¹, and nitrate levels varied between 2.25 and 11.75mg L⁻¹. In conclusion, salinity influences the growth of climbing perch in the biofloc system, with 6g L-1 identified as the most effective salinity level.
