This study aims to analyze the nutritional value of kalakai leaf fermentation-based feed that is feasible as Climbing Perch feed and analyze the growth performance of Climbing Perch raised by fermentation-based feeding of kalakai leaves. The specific target of this study is to increase the usability and usefulness of kalakai, a typical wetland plant as a feed for wetland-specific fish that can support growth and improve the health status of the fish being kept. The study was carried out using an experimental method on the maintenance of Climbing Perch which was fed based on fermented leaves with 5 treatments and 3 tests. The parameters observed are protein content, crude fiber, water, ash, and crude fat of fermented leaves based on kalakai leaves, weight, and length growth of Climbing Perch, survival, and feed conversion ratio. The results of the research on the nutritional content of feed showed that fermented feed on kalakai leaves has a protein content of 27%-31%, crude fiber content of 4%-7%, water content of 12%-14%, ash content of 11%-13% and crude fat of 4%-6%. It was concluded that there was a decrease in fiber levels and an increase in protein levels. It happens gradually in line with the increase in probiotic dose. The results of the study on the growth performance of Climbing Perch are: absolute weight growth ranges from 1.01-1.52 with the highest data in treatment C which is 1.47 and the lowest in treatment A which is 1.06, the growth of relative weight of Climbing Perch ranges from 28.61%-64.705% with the highest data treatment C which is 64.05% and the lowest treatment A is 28.61%, absolute length growth ranges from 1.41-2.37 with the highest data on treatment C which is 2.15 and the lowest in treatment A was 1.48, the relative length growth ranged from 31.60%-45.81% with the highest data on treatment C which was 45.81% and the lowest treatment A was 31.60%, survival ranged from 98.33-100% and the feed conversion ratio ranged from 3.87-14.83 with the lowest data on treatment C which was 5.56 and the highest obtained in treatment E was 12.20. The results of the nutritional content of feed based on the fermentation of kalakai leaves show that the value of crude fiber and protein is in the recommended range. The growth of Climbing Perch shows excellent development with high survival.
