Monitoring of water quality in the catfish (Clarias sp.) farming in Tuban Regency

Abstract

Fish need a decent environment for their life and livelihood. Types of fish that have different respiratory organs such as catfish can survive in extreme water conditions. However, in order to grow and develop naturally in a cultured environment, they need optimum water quality. This study aimed was to determine the quality of water in catfish aquaculture ponds in three partner locations for Community Service activities in Tuban Regency, East Java. The method used in this research is descriptive, with 3 points of location for water sampling, namely, in Jenggolo Village (A), Tegalagung Village (B), and Campurejo Village (C), Tuban Regency. The results of the study showed that the highest temperature in the pond in Campurejo Village was 30.2 °C. The highest pH in the pond in Tegalagung Village is 7.59. The highest dissolved oxygen in the pond in Jenggolo Village was 13.4 mg L-1. The highest nitrate level was in the pond in Tegalagung Village, namely, 25 mg L-1. The highest phosphate content in the pond in Tegalagung Village. Furthermore, the highest Total Ammonia Nitrogen (TAN) levels are in the pond in Tegalagung Village, which is 16.6 mg L-1. Based on the results, the water quality parameters were classified as great. However, some parameters are less than optimal at different locations. Water quality management needs to be developed to optimize the growth of catfish.
