    Overfishing contributes to the depletion of fish stocks. Among fishing practices, discarding fish is a waste of valuable resources and results in lost income that is associated with its effects on future stock growth. This practice depends on several factors, although trawl fisheries account for the highest quantity of discards. In this work, the effects of a specific section of the Galician (Northwestern

  • Micro‐Fishing as an Emerging Form of Recreational Angling: Research Gaps and Policy Considerations
    Fisheries (IF 2.701) Pub Date : 2020-06-07
    Steven J. Cook; Robert J. Lennox; Ben Cantrell; Andy J. Danylchuk

    Micro‐fishing is an emerging form of recreational angling that targets small‐bodied fish in inland and marine waters. Although most fish are presumably released, some are retained as specimens for home aquaria or dissection to confirm identification. To date, very little is known about the effects of micro‐fishing on individuals (e.g., stress, injury, mortality), populations, or communities owing to

  • Has Steller Sea Lion predation impacted survival of Fraser River Sockeye Salmon?
    Fisheries (IF 2.701) Pub Date : 2020-06-07
    Carl J. Walters; Murdoch K. McAllister; Villy Christensen

    The commercially, recreationally and culturally important Fraser River Sockeye Salmon Oncorhynchus nerka have experienced a productivity decline over the last three decades, which along with greater temporal variation in annual abundance (i.e. cyclic dominance) may at least partly be due to Steller Sea Lion Eumetopias jubatus (SSL) predation on returning adult salmon. This assumes that SSL residing

    Fisheries (IF 2.701) Pub Date : 2020-06-05
    Holly S. Embke; T. Douglas Beard; Abigail J. Lynch; M. Jake Vander Zanden

    Recreational fisheries have high economic worth, valued at $190B globally. An important, but underappreciated, secondary value of recreational catch is its role as a source of food. This contribution is poorly understood due to difficulty in estimating recreational harvest at spatial scales beyond a single system, as traditionally estimated from individual creel surveys. Here, we address this gap using

    Long‐term predator diet studies are powerful ecosystem monitoring tools, as has been illustrated by the use of seabird diets to assess the response of forage fish communities to changing ocean conditions (Thayer et al. 2008). In British Columbia, Chinook Oncorhynchus tshawytscha and Coho Salmon O. kisutch are good candidates for a long‐term predator diet study, due to their ubiquity in coastal waters

  • Development of Electrofishing for Fisheries Management
    Fisheries (IF 2.701) Pub Date : 2020-05-26
    James B. Reynolds; Jan C. Dean

    Electrofishing, broadly defined as the use of electricity to capture or control fish, was envisioned in an 1863 British patent application by Isham Baggs. Not until the 1920s, when large, stationary generators were available, did electrofishing applications (i.e., fish barriers) begin. After World War II , applications of electrofishing for fisheries management accelerated in diversity and portability

    Would you accept payment for your fisheries work in “company script” instead of cash? Paying impoverished employees with “company script” in leu of money is something we generally associate with coal operators, logging camps and others in the 19th century. However, in the leanest times of fisheries science during the Great Depression, research of one of AFS’s former Presidents, Homer Swingle (1957–1958)
