Eco enzymes are derived from the fermentation of organic matter, particularly fruit and vegetable peels, offering the advantage of being a versatile natural cleaning solution. They also serve as essential nutrients for plant and algae growth, while converting CO2 into carbon trioxide (CO3), which benefits marine plants and aquatic life. This study aimed to investigate the impact of providing alternative feed/companion in the form of eco enzyme liquid, composed of 90% organic matter from three types of fruit peels and 10% vegetable residues from fern plants, on the growth of Pangasius djambal in conventional fish ponds with peat water. The implementation of 1 litre of ecoenzyme per 100 ml of peat water in the fish ponds led to the enhancement of Pangasius djambal, resulting in increased weight and varying lengths. The correlation coefficient (>1) indicates a strong relationship between fish weight and length, suggesting that the total weight of the fish is directly proportional to its length. Moreover, the water quality standards, including physical, chemical, and biological parameters, in the conventional fish enlargement ponds with peat soil pond water type were well-maintained, preventing contamination from feed residues and fish feces, even after 28 days of fish enlargement.
