Effect of warming on European green crab (Carcinus maenas) populations from lar...
Monteiro, João Nuno; Ovelheiro, Andreia; SORDO, LAURA; Palma, Jorge; Pinto, Miguel; Teodosio, Maria; Leitão, FranciscoUnderstanding the effects of climate change on the physiology of marine species, particularly during their early life stages (larvae and juveniles), is essential for predicting population dynamics. Carcinus maenas is a widely distributed species of significant ecological and economic importance. This experimental study investigates the effects of warming on the early life stages of the European green crab, C. m...
Biological traits and population dynamics for sustainable harvesting of Carcinu...
Monteiro, João Nuno; Ovelheiro, Andreia; Maia, Francisco; Teodosio, Maria; Leitão, FranciscoResearch focusing on the biological patterns and population dynamics of Carcinus maenas has not been conducted for the purpose of fishery management along the European coastal systems. This has led to the implementation of fisheries management policies without scientific considerations, adversely affecting fishery profitability. To addrees this gap, we studied the crab species' population dynamics, reproductive...
Impact and size selectivity of fishing gears used in estuarine crab fisheries
Monteiro, João Nuno; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoCrustacean fisheries have expanded in the last decade due to the high economic value of the species. However, estuarine crustacean fisheries remain poorly studied compared with marine crustacean fisheries. In Portugal, the European green crab ( Carcinus maenas) may become increasingly important for the fishing industry and seafood production in general, especially in the current context of overexploitation of e...
Sustainable harvesting alone cannot prevent decline of the green crab fishery i...
Monteiro, João Nuno; Roa-Ureta, Ruben; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoEstuarine fisheries are of high regional socio-economic importance worldwide, by providing an important livelihood for many families. The Portuguese green crab (Carcinus maenas) fishery was assessed using a socio-economic assessment to understand the importance of the fishery and a stock assessment analysis to determine the exploitation status of the fishery during 1960-2020. Fisher knowledge revealed that crab...
