Estimating the unreported catch of Eritrean Red Sea fisheries

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

“…However, the values gathered through interviews should be checked against independently measured parameters, which can be used as an anchor to translate the interview data to an absolute scale, as is done, for example, when estimating unreported fisheries catches from anecdotes (Pitcher et al 2002, Tesfamichael andPitcher 2007).…”

Illegal, unreported and unregulated fisheries catch in Raja Ampat Regency, Eastern Indonesia

“…Since its original publication, the methodology has since been further refined and widely used, for example, for fisheries in the North Atlantic [17], Iceland and Morocco [18], British Columbia, Canada [19] and Eritrea [20]. The technique has two major advantages: (1) all available data on under-reporting, no matter what regulatory regime is in place, can be combined; and (2) uncertainty of estimates and trends can be addressed by applying a Monte Carlo simulation that uses likely error ranges [21].…”

“…), but the incentive is not worth the cost in terms of fuel, time and travel. Misool island has larger number of villages (20), compared to 3 villages in Kofiau [49]. The catch has good demand from employees of pearl farms in Misool.…”

“…We deliberately Mastrandrea et al (2010). a Percentage uncertainty derived from Monte-Carlo simulations (Ainsworth and Pitcher, 2005;Tesfamichael and Pitcher, 2007). b "Confidence increases" (and hence percentage ranges are reduced) "when there are multiple, consistent independent lines of high-quality evidence" (Mastrandrea et al, 2010).…”
