Effectiveness of Green Water System as Larval Gourami (Osphronemus gouramy) Cultivation Technology-Efforts to Increase Larval Productivity

Abstract

The crucial phase occurs at the larval stage, which often experiences mass mortality. The green water system is an aquaculture technology that offers a solution to increase larval survival and productivity. This study aims to determine the effectiveness of green water system technology in increasing larval survival and productivity. Experiments were carried out with three treatments: control without treatment, Green water using Spirulina sp. (T1), and Chlorella sp. (T2) with treatment replication units of 3 times each. The results showed that green water system cultivation technology had significant survival and final length compared to the control without treatment (p<0.05). Green water system technology effectively supports larval life by providing natural food and bioremediation mechanisms to convert organic matter in the environment so that a multi-trophic level balance occurs. This technology has a beneficial impact and has the prospect of being developed for broader applications in the future.
