Evidence of shifting baseline and Fisher judgment on lane snapper (Lutjanus synagris) management in a Brazilian marine protected area

Abstract The integration of knowledge from fishers and conventional scientific data is promising as a subsidy for the establishment of proper management procedures for fishing resources. In this context, the potential use of local ecological fisher knowledge from the Marine Extractive Reserveof Corumbau (MERC) in northeastern Brazil was evaluated regarding the shifting baselineof the lane snapper Lutjanus synagris. Semi-structured interviewswere carried out with 222 fishers who identified L. synagrisas the main fish resource used in MERC. The relationship between the maximum L. synagrisweight caught on the best fishing day among fishers of different age categories was not significant (p = 0.306). However, older fishers significantly (p
