Modern fisheries management is strongly based on ecosystem theory. Ecosystem management involves direct manipulation of the habitat and population as well as human activity in order to optimize sustainable returns to humans. The ecosystems approach is widely viewed as a new concept in management of fisheries and aquaculture. Ecosystems based...
The need for management of the marine ecosystem using a broad perspective has been recommended under a variety of names. This paper uses the term Ecosystem Management, which is seen as a convergence between the ecological idea of an organisational hierarchy and the idea of strategic planning with a planning...
There is increasing concern among fisheries scientists and managers over
the ecosystem effects of fisheries exploitation. This concern has been
motivated by several publications inferring that the structure of marine
ecosystems has been dramatically altered by historical patterns of fishing.
Among the most cited studies is the paper by Pauly...
Every fish species is part of a complex ecosystem which competes with
other species for resources. Likewise, the harvesting of fish species often
involves technological interactions which results in catching multiple
species as well as temporal interactions between species as fishermen
allocate their effort across multiple fisheries over the course...
Large-scale ecosystem assessments aim to assist ecosystem management by synthesizing current scientific knowledge on an area, and by providing a foundation for policy discussions and decisions on land management. These assessments go beyond traditional research efforts by moving away from narrow scope, system, and institutional boundaries, and by attempting to...
The push for ecosystem based management has opened up not only for including more of the natural
systems when managing fish resources, but also a broader perspective on the human systems, and the
diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries...
Explains terms and concepts used to discuss ecosystem management (biodiversity, habitat fragmentation, edge effects, interior species, corridors, population dynamics), including a glossary. Describes the importance of private forest lands in the stewardship of forest ecosystems. Provides suggestions for managing private property for wildlife.
This document provides definitions and a general overview of streams and lakes of San Juan County (SJC) and then describes impacts to these water bodies and strategies for determining widths of buffers that protect their functions. It similarly provides definitions and a general overview of SJC upland (terrestrial) habitats, describes...
There is a consensus in the scientific community that overexploitation of most fisheries worldwide has had significant negative effects on coastal marine ecosystems, and the majority of assessed fish stocks still require rebuilding programs. Almost all of the scientific studies conducted in recent decades have focused primarily on analysis related...
