STRUCTURAL IMPROVEMENT IN FISH HABITAT FOR SPORT FISHERIES - PROBLEMS AND APPROACHES

Habitat Complexity: Coral Structural Loss Leads to Fisheries Declines

Direct human impacts and global climate change are altering the composition and structure of coral reef habitats. These changes are simplifying size-abundance relationships of reef fish communities, reducing productivity through the system and ultimately threatening fisheries yields.

Quantitative Decision Analysis for Sport Fisheries Management

Fishery managers often are faced with difficult decisions on how to satisfy the socioeconomic need of the public while maintaining or restoring properly functioning aquatic systems. Such decisions are fraught with the complexity and uncertainty associated with ecological systems, multiple management objectives, and the alternatives under consideration (Varis and Kuikka 1999). To aid the decisio...

Economic Analysis of Protection of Essential Fish Habitat in Alaskan Fisheries: An Analysis of Research Needs

This report identifies the types of information necessary to evaluate the economic impacts of Essential Fish Habitat (EFH) protection and the gaps in the existing knowledge and research methodologies necessary for this evaluation. A discussion of the basic elements of a benefit-cost analysis or a cost-effectiveness analysis for essential fish habitat protective measures (EFHPM) is used to ident...

Estimating Fish Exploitation and Aquatic Habitat Loss across Diffuse Inland Recreational Fisheries

The current state of many freshwater fish stocks worldwide is largely unknown but suspected to be vulnerable to exploitation from recreational fisheries and habitat degradation. Both these factors, combined with complex ecological dynamics and the diffuse nature of inland fisheries could lead to an invisible collapse: the drastic decline in fish stocks without great public or management awarene...
