“…Perhaps the remaining 15 agencies have not suggested that barbless hooks are beneficial relative to barbed hooks because literature accounts are contradictory (e.g., Taylor and White 1992;Schill and Scarpella 1997;Turek and Brett 1997). However, there is compelling evidence that barbless hooks are easier to remove than barbed hooks (Diggles and Ernst 1997;Schaeffer and Hoffman 2002;Cooke et al 2001;Meka 2004).…”

Many recreational anglers practice catchand-release angling, where fish are returned to the water with the presumption that they will survive. However, not all fish survive, and those that do often experience sublethal consequences including injury and stress. There is compelling scientific evidence that angler behavior and gear choice can affect the success of catch-and-release as a management and conservation strategy. Because anglers often look to government natural resource agencies for guidance on how to handle and release fish properly, there is a need to assess whether their outreach materials are readily accessible and provide the necessary and correct information on the subject. Therefore, on-line catchand-release guidelines developed by state and provincial natural resource agencies across North America were evaluated to determine whether their guidelines were consistent with the best available scientific information. This analysis revealed that there was immense variation in the depth and breadth of coverage among jurisdictions. Agency guidelines contradicted one another in several areas including air exposure, angling in deep water, venting trapped gases, and resuscitation. In many cases, the guidelines failed to provide sufficient direction to actually be of use to anglers or provide direction consistent with contemporary scientific literature. This analysis will assist with developing outreach materials that promote sustainable recreational fisheries and in maintaining the welfare status of individual fish.

“…In a meta-analysis of salmonid hooking mortality, Taylor and White (1992) concluded that the use of barbed hooks caused higher mortality than the use of barbless hooks during baitfishing. However, other workers identified a flaw with this analysis, and concluded from the same data set that no difference in mortality between hook types was demonstrated (Schill and Scarpella 1997;Turek and Brett 1997). Responding to the criticisms, Taylor and White (1997) called for more primary research, recognizing that the number of existing trials of baited, barbless hooks was small.…”

Effect of Hook Type on Mortality, Trauma, and Capture Efficiency of Wild, Stream‐Resident Trout Caught by Active Baitfishing

We used an active fishing technique (tight‐line fishing with immediate hook set) to compare mortality, injury, and capture efficiency of wild, stream‐resident salmonids captured by barbed or barbless single hooks baited with leaf worms Lumbricus rubellus. Mortality at 72 h (2– 7%), anatomical hooking location (superficial or deep), and eye damage (5% of captures) in brook trout Salvelinus fontinalis did not differ between hook types. However, brook trout that were deeply hooked were more likely to die when barbed hooks were used. Mortality and eye damage in brown trout Salmo trutta were similarly low, but sample sizes were insufficient for comparison of hook types. Hook types did not differ significantly in terms of hooking efficiency, frequency of fish escape after hooking, or the mean unhooking time in which fish were held out of water. Active baitfishing resulted in levels of postrelease mortality that were substantially lower than those commonly reported in baitfishing mortality studies.

“…A substantial body of subsequent work has generally shown no significant difference in hooking mortality between nonanadromous salmonids (hereafter, trout) caught on barbed and barbless hooks regardless of whether bait, lures, or artificial flies were used (Thompson 1946, cited by Shetter andAllison, 1955; Hunsaker et al initiated some controversy when they used a dubious variant of a meta-analytical procedure to conclude that use of barbed hooks in baitfishing caused much more postrelease mortality of trout than barbless hooks (33.5% versus 8.4% mortality, respectively). This finding was subsequently criticized by several workers (Schill and Scarpella 1997;Turek and Brett 1997) because of an apparent flaw with their procedure.Despite considerable attention given to barbed-hook versus barbless-hook mortality over many years, the question remains unsettled as to whether barbless hooks reduce postrelease mortality when baitfishing for trout. For example, after their meta-analysis that largely showed barbed hook restrictions to be relevant socially but not biologically, Schill and Scarpella (1997) noted the possibility of some merit with the use of barbless hooks by bait anglers when releasing trout.…”

Hook Shedding and Mortality of Deeply Hooked Brook Trout Caught with Bait on Barbed and Barbless Hooks

We compared hook shedding rates, mortality, and bleeding of cultured brook trout Salvelinus fontinalis subjected to intentional deep hooking on size-6 barbed or barbless single hooks (with line cutting) baited with leaf worms Lumbricus rubellus. Hook shedding at the end of the 6week holding period averaged 20% and did not differ between hook types. Neither immediate mortality (average ¼ 12.5%) nor mortality after 5 d (average ¼ 20%) differed between hook types. Although we cannot demonstrate a survival advantage for cultured brook trout that were baitfished with barbless hooks over those caught on barbed hooks, we did find that significantly less bleeding was caused by barbless hooks. Further research examining whether the use of barbless hooks results in increased survival of wild brook trout or other trout species under different fishing conditions is warranted.Westerman (1932) reported that barbed hooks caused slightly more mortality than barbless hooks when brook trout Salvelinus fontinalis (size range ¼ 89-178 mm) were caught with bait at a Michigan fish hatchery, but the validity of this result has since been questioned for several methodological reasons (discussed by Schill and Scarpella 1997). A substantial body of subsequent work has generally shown no significant difference in hooking mortality between nonanadromous salmonids (hereafter, trout) caught on barbed and barbless hooks regardless of whether bait, lures, or artificial flies were used (Thompson 1946, cited by Shetter andAllison, 1955; Hunsaker et al. initiated some controversy when they used a dubious variant of a meta-analytical procedure to conclude that use of barbed hooks in baitfishing caused much more postrelease mortality of trout than barbless hooks (33.5% versus 8.4% mortality, respectively).

For example, after their meta-analysis that largely showed barbed hook restrictions to be relevant socially but not biologically, Schill and Scarpella (1997) noted the possibility of some merit with the use of barbless hooks by bait anglers when releasing trout. In addition, DuBois and Kuklinski (2004) found no statistical difference in overall mortality associated with barbed and barbless hooks in active baitfishing for wild brook trout, most of which were not deeply hooked. However, they noted that deeply hooked trout were significantly more likely to die when barbed hooks were used than when barbless hooks were used. Further, Jenkins (2003) surprisingly reported no mortality after 26 d in relatively large (mean fork length ¼ 254 mm) cultured rainbow trout Oncorhynchus mykiss that were deeply hooked on barbless Jhooks (5 mm between point and shank; evidently size 8). In that ...
