IDENTIFIKASI PENYAKIT NON-PATOGEN PADA IKAN NILA (Oreochromis niloticus) BERDASARKAN PARAMETER KUALITAS AIR DI KERAMBA PERAIRAN DESA MALI MALI SEBAGAI INDIKATOR IKAN SEHAT

This study aimed to assess the water quality parameters and identify non-pathogenic diseases as indicators of fish health in the Mali-Mali Village Watershed (DAS). The method employed was a survey conducted at the Mali-Mali Village Watershed in Banjar Regency, South Kalimantan. Water quality samples were collected using purposive sampling at observation stations located upstream, midstream, and downstream of the Mali-Mali Village Watershed. The parameters of temperature, pH, and DO were within ranges that supported the cultivation of Nile tilapia in fish cages at the Mali-Mali Village Watershed. However, the parameters of Ammonia and BOD were at levels that did not support the cultivation of Nile tilapia in fish cages at the Mali-Mali Village Watershed. Generally, no clinical symptoms of non-pathogenic diseases were found
