This chapter explores the evolving dynamics of marine resource management, emphasizing the role of fishers in shaping and managing marine environments. Traditionally viewed through the lens of extractivism, this chapter challenges the conventional understanding of domestication by highlighting the deliberate practices that fishing communities employ to ensure sustainable management of marine environments and resources. Through a case study in Baja California, Mexico, the chapter illustrates how local fishers, organized into cooperatives, actively engage in adaptive comanagement strategies that integrate traditional ecological knowledge and modern conservation principles. These strategies, which include selective harvesting, agglomeration, grazing, translocation, and the establishment of areas or reserves, reflect a growing awareness of the need to balance ecological resilience with community well-being. Recognizing the historical and contemporary role of human agency in marine ecosystems, the chapter advocates for management frameworks that incorporate diverse conservation strategies and local ecological knowledge (LEK). In doing so, it emphasizes the importance of collaborative approaches to fisheries management that address the challenges posed by climate change and overfishing and ultimately promote sustainable practices that ensure the long-term viability of marine resources for future generations.
