The Pink Shrimp fishery in the Southern Gulf of Mexico has dramatically declined from annual yields of about 24,000 metric tons in the mid-1950s to early 1970s to approximately 1,200 metric tons currently, with overfishing initially believed to be the primary cause. However, an inverse relationship between stock abundance and temperature, along with a decrease in recruitment and primary production since the 1970s, was noted, prompting the creation of a trophic model using Ecopath with Ecosim for ecosystem management. This model, which incorporates the Atlantic Multidecadal Oscillation as a climate change index, suggests that balanced harvesting at a 40% catch/biomass ratio for all resources is essential for sustainability, highlighting the inadequacy of conventional single-species management approaches.
