The shrimp industry has always relied on sustainable production to survive in this country. One of the solutions to achieve this goal, the prevention of pathogens and their carriers entering shrimp ponds, has been This study compared the efficacy of three-row with one-row water filtration systems in shrimp farms in Bushehr province. The three-row filtration systems consisted of different nets (1000, 500, and 250 microns), with three repetitions, while in the one-row system, only one row of 1000-micron mesh was used. These systems were utilized from the beginning to the end of the rearing period. This study analyzed data on unwanted shrimp, fish, and other species collected through the above systems. Based on the rearing period results, a three-row filtration system with 1000, 500, and 250-micron nets were the most effective in preventing entering particles (living and nonliving), unwanted organisms, eggs, and larvae of aquatic species. However, one-row filtration systems were the least efficient when compared to three-row systems in terms of efficiency. In addition, the number of unwanted organisms collected in shrimp processing centers confirms this issue. Also, in one-row filtration systems, increasing unwanted organisms caused a decrease in the production of 1300–2400 kg/ha, as well as profitability and increased production costs on farms. Compared the performance of the three-row filtration system was higher than that of one-row filtration. Any increase in unwanted organisms in shrimp ponds can lead to diseases because they are pathogen agent carriers. The results obtained indicated that farmers should use sand and micron filters with 1000 (row 1), 500 (row 2), and 250 (row 3) microns, respectively, to improve production, prevent pathogenic agents from entering, and reduce disease risk.
