文摘
- •
A method to estimate the relative catch efficiency of different fishing gear.
- •
Assess effect of gear changes on catch efficiency for a Spanish longline fishery.
- •
Results demonstrated that a thicker snood line reduced catch efficiency on hake.
- •
Hook type and snood line length used had no effect on the efficiency of the fishery.
