2. 'The sea is our life'. Woman in the fishery sector of the Valencian Community.

Traditionally the role of women in fishing has gone largely unnoticed, but now in recent years there has been a growing interest about them. However, the task of identifying and quantifying the role played by women in fisheries has yet to be fully developed. This study tackles the role of women in...

3. Population effect of a large-scale stream restoration effort on Chinook salmon in the Pahsimeroi River, Idaho.

Stream habitat restoration is an important tool for fisheries management in impaired lotic systems. Although small-scale benefits of stream habitat restoration are commonly investigated, it is difficult to demonstrate population effects. The Pahsimeroi River Chinook salmon Oncorhynchus tshawytscha...

13. Effect of gear design on catch damage on cod (Gadus morhua) in the Barents Sea demersal trawl fishery.

Damage incurred during the catch process is an indicator of the overall quality of fish and fish welfare. Because catch quality is difficult to improve once it has deteriorated, it is important to preserve quality during the catch process. Atlantic cod (Gadus morhua) is the most important species...
