Location-specific consequences of beach seine and gillnet capture on upriver-migrating sockeye salmon migration behavior and fate
Fish released after capture, or fish interacting with gear but escaping, sometimes experience fishing-related incidental mortality (FRIM). For adult Pacific salmon migrations, knowing the magnitude of FRIM is important to estimate escapement accurately and to understand the total impact of a specifi...

description | Fish released after capture, or fish interacting with gear but escaping, sometimes experience fishing-related incidental mortality (FRIM). For adult Pacific salmon migrations, knowing the magnitude of FRIM is important to estimate escapement accurately and to understand the total impact of a specific fishery. To determine how multiple gear types are associated with FRIM at different levels of maturity, we captured sockeye salmon (Oncorhynchus nerka) by both gill net and beach seine at three locations along their migration route (10%, 26%, and 72% of a 500 km freshwater migration) and determined their migratory success using biotelemetry. FRIM was higher for fish captured by gill net except at the location closest to spawning grounds. In addition, salmon captured by gill net at the lower river locations temporarily delayed migration, potentially indicating a requirement for lengthier recovery time compared with beach-seined fish. These results provide the first empirical and parallel comparison of these two common in-river fishing methods for salmon, revealing clear differences in FRIM between the two fishing methods in lower river fisheries and the importance of maturity. |
