Length-Based Spawning Potential Ratio (LB-SPR) for Red Grouper (Epinephelus morio) and Associated Species in the Commercial Fishery of the Yucatan Peninsula, Mexico

Figure 5

Bar plot illustrating the Spawning Potential Ratio (SPR) using the LB-SPR Model for the red grouper fishery and its associated species. The black dotted line indicates the SPR reference value, while the red dotted line represents the critical minimum SPR value and whiskers denote the 95% confidence intervals. A SPR below 0.20 suggests an elevated risk of decline, particularly in the supply of juvenile fish.
