Abstract

Catfish (Clarias sp.) is one of the economically important freshwater fish that has been widely cultivated both traditionally and intensively. Catfish has many advantages such as fast growth, resistance to disease, and can live in water conditions that are low in oxygen content. The use of microbubble technology is expected to support the performance of catfish farming with a biofloc system. With the application of this technology, it is hoped that the oxygen supply from micro-sized air bubbles will increase. Because the diameter of the air bubble is less than 50 µm, it is expected to last a long time in the water and can spread horizontally so that it can be utilized optimally by catfish and biofloc. The purpose of this study was to evaluate the effectiveness of microbubble technology on the growth performance of catfish. The research method used a completely randomized design, with 4 treatments and 3 replications. The variables measured during the study included survival rate, length and weight growth, specific growth rate, feed conversion ratio (FCR), and water quality including temperature, dissolved oxygen (DO), pH, ammonia (NH3), nitrite (NO2-), nitrate (NO3-), oxygen consumption rate (OCR), and total organic matter (TOM).

Abstract

This study evaluates the suitability of water quality in the Lingsar Sub-watershed, West Lombok, for the cultivation of tilapia (Oreochromis niloticus), gourami (Osphronemus gouramy), and catfish (Clarias gariepinus). Field measurements were conducted during June–July 2024 across several sampling points. Key water quality parameters were assessed and compared with established aquaculture standards and the physiological requirements of each species. The findings indicate that the general water quality conditions, including temperature, pH, dissolved oxygen, and levels of nitrogen compounds, support the growth of all three species. The sub-watershed is highly suitable for more tolerant species such as catfish and tilapia, while gourami cultivation is also feasible with more intensive management. It is concluded that the Lingsar Sub-watershed holds considerable potential for development as an integrated aquaculture zone. Sustainable development through regular water quality monitoring and the adoption of eco-friendly technologies is recommended.
