Poaching and excessive fishing have led to a significant decline in the population of native fish species in the southern part of Tamaulipas, Mexico. The issue is exacerbated by the lack of surveillance in the region's water bodies. As a result, traders like Gustavo Gutiérrez Guerrero in Tampico have seen a drastic reduction in their catch, with some species seeing an 90% drop. This problem is further complicated by the unequal shrimp ban between Mexico and the US, and the disregard for fishing bans by unauthorized fishermen. Authorities, along with sport fishing clubs, are calling for increased enforcement to combat poaching and preserve marine life. The decline in fish numbers not only impacts traders but also threatens the tourism potential of Miramar beach, as it hinders large fish catches necessary for tournaments.
