Reproductive traits of the African mud crab (Panopeus africanus) on the South P...
N. Monteiro, J.; Ovelheiro, Andreia; Pinto, Miguel; Teodosio, Maria; Leitão, FranciscoSpecies with high economic relevance are widely studied in contrast with low economic relevance species such as Panopeus africanus, a small crab with a wide distribution along the eastern Atlantic coast, which remains poorly studied in regarding to the biological and ecological issues. Knowledge of reproductive patterns is essential to understand populations dynamics and species biological life-cycle traits. Th...
Socioeconomic importance of the small-scale Mud Crab fishing (Scylla Serrata, F...
Manuessa, Bonifácio; Cuinhane, Calmila J. O.; Borges, Teresa Cerveira; Teodosio, Maria; Leitão, FranciscoMud crab fishing (Scylla serrata) is an important activity contributing to the livelihood of coastal communities in Mozambique. The abundance of this crab and the increase in international companies in the region that exclusively buy crabs and export to the Asian market have caused fisheries to gain local importance in recent years. The present study evaluates the socioeconomic importance of mud crab fishing an...
The diversity of fish larvae in the Bons Sinais Estuary (Mozambique) and its ro...
Mocuba, Jeremias; Leitão, Francisco; Teodosio, MariaThe study of assemblages of fish in their early phases in estuaries is an essential approach to understanding the functioning of these types of ecosystems and their role as nursery grounds for some marine fish species. The main aim of this study was to analyze the ichthyoplankton assemblage in the Bons Sinais Estuary, specifically to clarify the use of this area by species of socio-economic interest. This study...
The influence of upwelling on key bivalves from the Humboldt and Iberian curren...
García-Huidobro, M. Roberto; Aldana, Marcela; Varela, Pablo; García-Herrera, Claudio; Monteiro, Luís; Leitão, Francisco; Teodosio, MariaEastern Boundary Upwelling Systems (EBUS) deliver cold, nutrient-rich waters, influencing coastal biota from the molecular to the ecosystem level. Although local upwelling (U) and downwelling (DU) conditions are often known, their influence on body attributes of relevant species has not been systematically compared within and between EBUS (i.e., below and above regional scales). Hence, we compared the physical-...
Sowing potential transformative changes in the fishing and agrifood systems – c...
Moranta, Joan; Florido-del-Corral, David; López-López, Lucía; Gómez, Sílvia; Agujetas, Julio; Albo Puigserver, Marta; Brent, Zoe W.; Bathily, LamineThe need to better understand the trade-offs between food production, trade and consumption; social and environmental impacts of food systems and food health requirements remains a challenge. Additionally, there is an urgency to transform the food system to reach the dietary patterns required to address the current diet -environment-health trilemma. Transformative changes are required to deal with the food syst...
Macro and microscopic maturation stage key of green crab (Carcinus maenas, Linn...
Ovelheiro, Andreia; N. Monteiro, J.; Gonçalves, Patrícia; Campinho, Marco António; Maia, Francisco; Teodosio, Maria; Leitão, FranciscoGonadal histology is a helpful tool to validate species' macroscopic maturity stages in fisheries biology. Regardless of the many studies on Carcinus maenas, there are still few concerning gonads tissue histology and description of maturity stages. In Portugal, information regarding this species' biology to help support the regulation of crab fisheries, including the minimum landing size, has not yet been defin...
Revealing the role of crab as bait in octopus fishery: an ecological and fishin...
Leitão, Francisco; Monteiro, J. N.; Cabral, Pedro; Teodosio, Maria; Roa-Ureta, Ruben H.In southern Portugal, artisanal octopus fisheries play an important socioeconomic role. Live crab bait in traps was used up to 2010 and banned in 2012. Such regulation, based on co-management advice, was not established under a scientific fundament. As a result, a long-standing controversy ensued with some fishing associations claiming that live crab bait increased fishing effort and exploitation rates and ther...
Eco-socio-economic vulnerability assessment of Portuguese fisheries to climate ...
Pinto, Miguel; Albo-Puigserver, Maria; Bueno-Pardo, Juan; N. Monteiro, J.; Teodosio, Maria; Leitão, FranciscoUnderstanding ecological, and socio-economical vulnerabilities is fundamental towards developing and implementing regional adaptation strategies to climate change. The Portuguese coast is situated in a transition zone between temperate ecosystems to the north, and subtropical with Mediterranean characteristics, to the south, with distinct oceanographic regions (north, centre, and south), fish assemblages and so...
Environmental variability and fishing effects on artisanal flatfish fisheries a...
Baptista, Vânia; Blasco, Ignacio Pérez; Bueno-Pardo, Juan; Teodosio, Maria; Leitão, FranciscoAssessing the effects of fishing activity and environmental variability on fishing species might help to understand their fluctuations and to manage them accordingly. However, despite the increasing number of studies linking fisheries and environmental data, few had a multi-species approach considering flatfish species and different age groups. Therefore, this study aims to determine the effects of environmenta...
Ecological sensitivity and vulnerability of fishing fleet landings to climate c...
Albo Puigserver, Marta; Bueno-Pardo, Juan; Pinto, Miguel; N. Monteiro, J.; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoThe degree of exposure of fishing communities to environmental changes can be partially determined by the vulnerability of the target species and the landings composition. Hence, identifying the species that ecologically most contribute to the vulnerability of the landings are key steps to evaluate the risk posed by climate change. We analyse the temporal variability in intrinsic sensitivity and the ecological ...
