Research Article: Optimizing shrimp growth and yield production: A comparative study of Pacific white shrimp farms along the Persian Gulf coastline

This study aimed to compare the growth and yield of shrimp in different farms of the Heleh (H۱, H۲, and H۳) and Shif (S۱, S۲, and S۳) shrimp farming complexes and investigate the correlation between stocking density, aeration rate, automatic feeder usage, culture period, and harvested yield. Statistical analysis was performed to compare means for average daily growth rate, mean body weight, final yield (ton), survival rate (SR %), feed conversion ratio (FCR), and specific growth rate (SGR) across different farms. The results showed significant differences (p<۰.۰۵) between different farms for the parameters under investigation in the Heleh shrimp farming complex, while for Shif, no significant differences were found between different farms for average daily growth rate, FCR, and SGR (p>۰.۰۵). However, significant differences (p<۰.۰۵) were observed in SR (%), mean body weight, and final yield between different farms in Shif. Further analysis using Pearson correlation showed a high correlation (R>۰.۹) between the production level and the stocking density, aeration rate, and culture period. While the production level increased with an increasing number of automatic feeders, no significant correlation was found between these two parameters. Additionally, a positive correlation was observed between the SR (%) and the stocking density and the number of aerators. These results provide valuable insights into the factors that influence shrimp growth and yield, which can be useful for the development of more efficient and sustainable shrimp farming practices in both Heleh and Shif shrimp farming complexes.
