Nutrient Loading Increases Red Snapper Production in the Gulf of Mexico
Joshua M. Courtney, Amy C. Courtney, Michael W. Courtney

TL;DR
This study hypothesizes that increased nutrient loading from rivers and artificial structures has significantly boosted red snapper populations in the northern and western Gulf of Mexico, contrasting with declines elsewhere.
Contribution
It introduces the novel hypothesis that nutrient loading and artificial reefs synergistically enhance red snapper populations in specific Gulf regions.
Findings
Nutrient loading increased nearly 300% since 1950.
Red snapper populations shifted towards nutrient-rich northern and western Gulf.
Artificial structures may work with nutrient loading to support red snapper growth.
Abstract
A large, annually recurring region of hypoxia in the northern Gulf of Mexico has been attributed to water stratification and nutrient loading of nitrogen and phosphorus delivered by the Mississippi and Atchafalaya rivers. This nutrient loading increased nearly 300% since 1950, primarily due to increased use of agricultural fertilizers. Over this same time period, the red snapper (Lutjanus campechanus) population in the Gulf of Mexico has shifted strongly from being dominated by the eastern Gulf of Mexico to being dominated by the northern and western Gulf of Mexico, with the bulk of the current population in the same regions with significant nutrient loading from the Mississippi and Atchafalaya rivers and in or near areas with development of mid-summer hypoxic zones. The population decline of red snapper in the eastern Gulf is almost certainly attributable to overfishing, but the cause…
