Jurisdictional and administrative limitations affecting management of the halibut fishery

Management of living resources in the northeast pacific and the unilateral extension of the 200‐mile fisheries zone

“…Halibut statistics for the area have been described as perhaps the longest and most complete in the world. (Skud, 1976.) A recent comparison of the statistical area divisions of the various management commissions and agencies (Ehrhardt and Bledsoe, 1975) in the Northeast Pacific shows an incredible difference in the areas covered by each.…”

“…(Skud, 1976.) According to short-term indications, the halibut stock recruitment showed signs of increase by the mid-1970s.…”

“…There is some small catch of halibut in Canadian waters by United States citizens and a larger Canadian harvest of halibut from United States waters in the Gulf of Alaska. (Skud, 1976.) The North Pacific Fisheries Management Council has established a working team to consider various alternative arrangements for halibut management.…”

New technologies to improve bycatch mitigation in industrial tuna fisheries

“…While being repeatedly bitten by sharks, due to their shape, circle hooks roll and slide more so than J‐shaped hooks, perhaps creating a higher probability that circle hooks will become oriented so that it lodges. Factors such as “hook‐spacing” and “bait loss” have been investigated in demersal longlines (Monnahan & Stewart, 2018; Skud, 1978) where catch rates can be affected by the “hook‐spacing” and thereby impact catching efficiency in Pacific halibut fisheries (Bjordal & Lokkeborg, 1996). Moreover, it was reported that bait loss was correlated with soak time and loss was lower for firm‐bodied bait, such as squid (Shomura, 1955; Ward & Myers, 2007).…”
