Abstract

This article focuses on characterizing the salinity tolerance of Hogfish (Lachnolaimus maximus) to develop low-salinity aquaculture protocols. Through four experiments, the study found that Hogfish can survive acute transfers to salinities as low as 8 g/L for short durations and tolerate rapid transfers to salinities of at least 12 g/L without significant physiological stress. Long-term growth at 16 g/L salinity was comparable to that at full-strength seawater (32 g/L), suggesting potential cost savings by reducing saltwater use in recirculating aquaculture systems. However, feed conversion ratios were high, likely due to feeding behavior and fish age, indicating a need for improved diets and further research on salinity tolerance across life stages to optimize culture conditions.
