What can ecology contribute to ecosystem-based management?

Area of Science:

• Marine ecology
• Fisheries science
• Ecosystem management

Background:

• Modern fishing practices significantly alter marine environments, impacting seafloor habitats, food webs, and ecosystem functions.
• Current management strategies often lack a holistic view, failing to account for the complex interactions within marine ecosystems.

Purpose of the Study:

• To highlight the urgent need for integrating diverse ecological information for effective ecosystem-based management.
• To advocate for an expanded definition of essential fish habitat that includes critical food-web dynamics.
• To emphasize the importance of considering interactive stressors and ecosystem functions for maintaining marine ecosystem resilience.

Main Methods:

• Review and synthesis of existing ecological, oceanographic, and fisheries data.
• Conceptual framework development for ecosystem-based management.
• Analysis of the role of ecosystem functions in adaptive capacity.

Main Results:

• Disturbing the sea floor, altering food webs, and shifting ecosystem functions are key impacts of modern fishing.
• Integrating natural history, oceanographic, habitat, behavior, and ecological information is essential for effective management.
• Expanding essential fish habitat to include food-web relationships is critical.

Conclusions:

• A broader perspective encompassing ecosystem functions and interactive stressors is necessary for maintaining ecosystem vitality and resilience.
• Maintaining multiple ecosystem functions enhances adaptive capacity to environmental changes.
• An ecological understanding of resilience requires embracing uncertainty and employing diverse human management approaches to preserve ecosystem functions.
