- Diets of the sole Solea vulgaris Quensel, 1806 and Solea senegalensis Kaup, 1858 in the lower estuary of the Guadiana River (Algarve, southern Portugal): Preliminary resultsPublication . Sá, R.; Bexiga, C.; Vieira, L.; Veiga, Pedro; Erzini, KarimThe feeding habits of two major species of sole, the common sole Solea vulgaris Quensel, 1806 and the Senegalese sole Solea senegalensis Kaup, 1858 were studied in the lower estuary of the Guadiana River (Algarve, southern Portugal). An evaluation of the number, weight, and feeding coefficient of prey types showed that S. vulgaris feed on a limited variety of prey (only Polychaeta and Tanaidacea) and present low-intensity feeding activity, with small differences in diet between seasons. S. senegalensis also have a low-diversity diet (with only one more taxa, Amphipoda), but exhibit more intense feeding activity which varies seasonally, although with little seasonal variation in the relative importance of the main preys. The diet composition of these two species suggests feeding specialization.
- Research and management priorities for Atlantic marine recreational fisheries in Southern EuropePublication . Pita, Pablo; Artetxe, Inaqui; Diogo, Hugo; Gomes, Pedro; Gordoa, Ana; Hyder, Kieran; Pereira, Joao; Pita, Cristina; Rangel, Mafalda; Garcia-Rodrigues, Joao; Sague, Oscar; Veiga, Pedro; Vingada, Jose; Villasante, SebastianMarine Recreational Fishing (MRF) is an important activity in Europe, with 9 million fishers and generating annually 6 billion in direct expenditures. However, there is a lack of data and understanding of MRF in Europe, particularly in Southern countries, which prevents a number of fish stocks from being effectively assessed and managed. In November 2016, a participatory workshop on MRF was held in Vigo (Spain) to identify challenges and opportunities for data collection, and to diagnose key research gaps and management issues for MRF in the Southern European Atlantic. Experts from a wide range of disciplines (researchers, policy makers, fisheries managers and commercial and recreational fishers) highlighted that the management of MRF is a challenge due to complex and dispersed legal frameworks, with multiple administrations involved, and overlapping uses of space with commercial fishing, aquaculture, navigation and tourism, among others. The lack of strong and representative fishing associations hampers research and management initiatives. Effective communication between recreational fishers, researchers and fisheries managers is also lacking. Despite the ecological, social and economic relevance of MRF, there is no systematic and comprehensive collection of information on fishing effort, recreational catches, expenses, social profile and access conditions of European recreational fishers. These data would be useful to avoid biases in the assessment of recreational fisheries due to the great diversity of ecosystems, species and typologies of users. Strategic recommendations and research priorities were also identified to address knowledge gaps and are discussed in the context of the management of MRF across Europe.
- First record of the Mediterranean parrotfish, Sparisoma cretense in Ria Formosa (south Portugal)Publication . Abecasis, D.; Bentes, Luis; Ribeiro, Joaquim; Machado, Daniel; Oliveira, Frederico; Veiga, Pedro; Gonçalves, J. M. S.; Erzini, KarimSeveral juvenile specimens of Sparisoma cretense, a previously unrecorded species, were caught using beach seining in Ria Formosa.The hypothesis that these occurrences are related with climatic changes is discussed.
