Many of the world's fisheries are in trouble - they no longer yield the catches, and potential profits, they once did. The habitats that support fisheries have been damaged by pollution and other irresponsible use of coastal land. Destructive fishing methods like trawling and blast fishing have also changed fish habitats resulting in support of fewer fish.
The authors draw on more than 1000 scientific papers covering 11 groups/species of marine invertebrates. From this large literature, they distill 20 lessons for assessing and guiding the use of restocking and stock enhancement in the management of invertebrate fisheries.
- Written by 7 expert authors
- Covers 11 groups/species of marine invertebrates
- Reviews over 1000 scientific papers
- Identifies 20 lessons that can be learned from past restocking and stock enhancement initiatives
- Proposes a new approach to assess the potential value of hatchery releases to
complement other forms of management
- Assesses progress of disciple against the blueprint for a responsible approach
