Abstract

This study investigated the structural relationships between laver production (PR) and environmental factors in the Haenam coastal area using climate and oceanographic data collected from September 2022 to April 2025. A structural path analysis model (L-Path) was constructed based on correlation analysis and tested using SmartPLS 4.0 to evaluate direct and mediating effects. Air temperature (AT) had a significant positive effect on seawater temperature (ST), whereas ST negatively affected salinity (SL) and dissolved oxygen (DO). Both SL and DO showed significant positive direct effects on PR, and indirect pathways such as AT→ST→SL→PR and AT→ST→DO→PR were statistically significant. Rain falls (RF), sunshine duration (SD), and nutrients (DIN, DIP) showed no significant direct effects on PR. These results suggest that laver production in the Haenam region is primarily regulated by a hierarchical mechanism in which climatic factors influence physical conditions, subsequently altering chemical properties that control biological production.
