Modular system innovation for increasing milkfish production on traditional ponds in Usto village, Mare district, Bone

One of the milkfish cultivation techniques (Chanos chanos) to increase pond productivity is a modular system. Modular system is a pond cultivation technique with a tiered plot model, where connecting between ponds is made, the purpose of which is to make milkfish easily move between ponds. The purpose of this study is to analyze the effectiveness of modular system innovation techniques (tiered plots) in increasing the production of bait milkfish in traditional ponds in Usto Village, Mare District, Bone. The research was conducted from August to the end of November 2023, at the location of the 2023 Matching Fund - Kedaireka program in a traditional pond in Usto Village, Mare District, Bone Regency, South Sulawesi Province. The research method used is a quantitative research method with a type of experimental research. Primary data measurements include; water quality measurement, including; temperature, salinity, pH and dissolved oxygen. While the parameters of the organization include the length of the fish from stocking to harvest. The data analysis method used is descriptive statistical analysis, in order to obtain an overview of the success of modular system techniques in traditional ponds. The results of the study obtained that the modular system technique can increase fish growth quickly, with the process of transferring fish periodically between ponds, making fish experience different conditions and physiological conditions that feel new. The modular system provides an average fish growth rate of 4.5 cm within 3 months or an average of 0.15 cm per day, with the highest rate occurring in rearing pond I, which is during the initial phase of post-stunting maintenance, which is an average growth rate of 6.2 cm per month, or 0.21 per day. Thus, this modular system technique can be used to increase the productivity of traditional ponds.
