Comparing Fisher Interviews, Logbooks, and Catch Landings Estimates of Extraction Rates in a Small-Scale Fishery

Assessing Changes in Fisheries Using Fishers’ Knowledge to Generate Long Time Series of Catch Rates: a Case Study from the Red Sea

“…Even the most independent abundance measurement, the underwater visual census, had sampling problems, e.g., depth limitation, and there was also a mismatch between the area sampled by the visual census and the fishing grounds (Daw 2008, Daw et al 2011. O'Donnell et al (2012) compared CPUE data from interviews, logbooks, and official catch landing records. Although they found that all sources showed similar trends, absolute CPUE values from interviews were higher and more variable.…”

Methodological considerations when using local knowledge to infer spatial patterns of resource exploitation in an Irish Sea fishery

“…The queen scallop fishery is ephemeral in nature, thus while fishers may identify a broader landscape of suitable fishing grounds that produced catches in previous years, it may not relate to the current fishing season. Thus we provide further evidence that LK reliability and precision can vary between fisheries and species (Gilchrist et al, 2005;O'Donnell et al, 2012). This highlights the importance of appraising LK data on a case by case basis, and the benefit of having some prior knowledge of a community, or preliminary study, to ensure a representative sample is obtained.…”

“…More recently, researchers have sought to establish sources of bias and error in LEK but they remain poorly understood, and its use has therefore http://dx.doi.org/10.1016/j.biocon.2014.10.013 0006-3207/Ó 2014 Elsevier Ltd. All rights reserved. been challenged (Folke, 2004;Gilchrist et al, 2005;Hill et al, 2010;Leite and Gasalla, 2013;O'Donnell et al, 2012;Teixeira et al, 2013;Zukowski et al, 2011). Decisions made through the interpretation of inaccurate data could lead to flawed management strategies (Ludwig et al, 1993), therefore there is a pressing need to understand more fully the reliability of LEK and its value to management (Folke, 2004).…”

“…The communities of people who live and interact with species, habitats and resources are increasingly considered as a valuable source of quantitative data (Danielsen et al, 2005;Gilchrist et al, 2005;Hill et al, 2010;Jones et al, 2008;Moreno et al, 2007;O'Donnell et al, 2012). Participatory monitoring (PM) and local ecological knowledge (LEK) are forms of community derived data that are gaining recognition.…”

Identification and Characterization of Métiers in Multi-Species Artisanal Fisheries. A Case Study in Northwest Spain

“…To do so, 30 demersal fleets from Denmark, the United Kingdom (England), the Netherlands, France and Spain were investigated, but in almost all the cases, vessels chosen for the project registered total length ranges above 10 -12 metres, as well as a weak representativeness of so-called small-scale fisheries 4 . In many cases identification and characterization of artisanal métiers have been carried out based on alternative approaches such as onboard samples or surveying methods [10] [11] [30]- [32], although researchers have also pointed out reliability problems that may arise when data elicited from resource users are employed [33]. Nevertheless, there is no precedent in exploring the potential of other sources of information to identify and characterize poor-data artisanal fisheries, as for example the administrative registers of fishing licences used by artisanal vessels: in many South-European coastal regions, artisanal vessels are required to communicate to fishing Administration each daily change in the fishing gears they used (equivalent to different artisanal fishing licences), so that it supplies an interesting source to be applied in monitoring their activity.…”
