Fishermen´s perceptions of interactions between seabirds and artisanal fisheries in the Chonos archipelago, Chilean Patagonia [PDF]

, 2013
Interactions between seabirds and commercial fishing activities have been well documented but little information is available regarding the impacts of more traditional fishing practices on seabird populations.

Tori lines mitigate seabird bycatch in a pelagic longline fishery [PDF]

Reviews in Fish Biology and Fisheries, 2021
Albatross bycatch has been increasing over the past decade in the US tuna longline fishery of the central North Pacific. A controlled field experiment was used to assess the efficacy of bird scaring or tori lines as a seabird bycatch mitigation measure for this fishery in a 3-factor sampling design with other mitigation methods (blue-dyed bait, offal ...

Enhanced data collection in the Canadian Arctic for seabird bycatch information yields highly variable results

Arctic Science
Incidental catch of seabirds (bycatch) in fisheries has been identified as a major threat to the conservation of seabird populations. Acquiring accurate, detailed data on seabird bycatch is an ongoing challenge to effective integrated ecosystem ...

Evaluating the potential effectiveness of compensatory mitigation strategies for marine bycatch. [PDF]

PLoS ONE, 2008
Conservationists are continually seeking new strategies to reverse population declines and safeguard against species extinctions. Here we evaluate the potential efficacy of a recently proposed approach to offset a major anthropogenic threat to many ...

Using the empirical Bayes method to estimate and evaluate bycatch rates of seabirds from individual fishing vessels [PDF]

, 2007
Minimizing bycatch of seabirds is a major goal of the U.S. National Marine Fisheries Service. In Alaska waters, the bycatch (i.e., inadvertent catches) of seabirds has been an incidental result of demersal groundfish longline fishery operations. Notably,

Reducing seabird bycatch in the Hawaii longline tuna fishery [PDF]

Endangered Species Research, 2008
Mortality in longline fisheries represents a global threat to some species of pelagic seabirds. Regulations were adopted in 2001 to reduce seabird bycatch in the Hawaii longline tuna fishery. We used a Poisson generalized additive regression modeling approach to evaluate the change in seabird bycatch rates from the pre- to post-regulation period, and ...

Temporally‐indexed multi‐species density impact functions: Quantifying timing and impact of invasive predators on seabird breeding success

Conservation Science and Practice, EarlyView.
Conserving threatened species often requires effective predator suppression strategies, particularly on islands where introduced predators pose significant threats. Density‐impact functions provide a framework to quantify the relationships between predator abundance and impact but are currently limited to a single species with invariant impact.

Commercial viability of locating pelagic longline branchline weights at the hook to reduce seabird bycatch

Endangered Species Research, 2020
Bycatch in pelagic longline fisheries threatens the viability of some seabird populations and reduces fishing efficiency. The mass of a branchline fishing weight and its distance from the hook significantly explain seabird catch risk during setting and ...

Seabird bycatch by tuna longline fisheries off southern Africa, 1998–2000 [PDF]

South African Journal of Marine Science, 2002
The incidental mortality of seabirds in tuna longline fisheries is estimated for the continental South African Exclusive Economic Zone (EEZ). Fishery observers accompanied 13 fishing trips and observed 108 sets (143 260 hooks) during the period 1998–2000.
