- ESTADO DOS STOCKS EM 2020 E ACONSELHAMENTO CIENTÍFICO PARA A SUA GESTÃO EM 2021Publication . Costa, Ana; Rocha, Alberto; Pereira, Bárbara; Maia, Catarina; Chaves, Corina; Silva, Cristina; Rosa, Daniela; Feijó, Diana; Mendes, Hugo; Farias, Inês; Figueiredo, Ivone; Wise, Laura; Gaspar, Miguel B.; Lagarto, Neide; Gonçalves, Patrícia; Lino, Pedro; Alpoim, Ricardo; Coelho, Rui; Garrido, Susana; Moura, Teresa; Stratoudakis, Yorgos; Instituto Português do Mar e da Atmosfera, I.P.This report presents the stock assessment results for the species exploited by Portugal in 2020 and the scientific advice for their management in 2021. For each resource the stock distribution area, the source for the scientific advice, the biological reference points, the state of exploitation and scientific advice and the management measures.
- A investigação realizada no IPMA de suporte ao aconselhamento científico para a gestão de espécies de raiasPublication . Serra-Pereira, Bárbara; Maia, Catarina; Lagarto, Neide; Figueiredo, Ivone; Instituto Português do Mar e da AtmosferaIPMA is responsible for the study and scientific advice on the state of exploitation of some skate species with commercial interest. About 80% of skate and ray species’ landings are by-catch from the Portuguese polyvalent fleet, consisting of vessels holding licenses for various fishing gears (e.g. trammel nets, gillnets, longlines) and operating on the Portuguese continental shelf. The five species with more commercial interest are: thornback ray, Raja clavate; blonde ray, R. brachyura; spotted ray, R. montagui; cuckoo ray, Leucoraja naevus; and undulate ray, R. undulata. The Common Fisheries Policy of the European Union is responsible for the management of each skate stock. The management tool used is the establishment of Total Allowable Catch (TACs). In Portugal, additional technical management measures (e.g. seasonal closure, minimum catch size) were also legislated. The quality of scientific advice on exploitation state of the different stocks of skates, which for ICES Division 27.9a (including Portugal and Spain) is done every two years since 2014, is strongly dependent on the quality of available information, particularly on the biology and dynamics of these species and on their fisheries. The economic and social importance of these fisheries for fishing communities makes the research carried out at IPMA fundamental to increase the knowledge on skate and ray species and provide scientific advice for the management of the different stocks occurring in mainland Portugal. This report gives an overview of the research studies carried out at IPMA/IPIMAR since 2003.
- O LABORATÓRIO DE ESCLEROCRONOLOGIA E OS ESTUDOS DE IDADE E CRESCIMENTO DE RECURSOS DA PESCAPublication . Farias, Inês; Soares, Eduardo; Moreno, Ana; Ferreira, Ana Luísa; Silva, Andreia; Serra-Pereira, Bárbara; Dinis, David; Morais, Delfina; Silva, Dina; Santos, Eduardo; Meneses, Isabel; Ferreira, Maria João; Lagarto, Neide; Gonçalves, Patrícia; Alpoim, Ricardo; Dores, Sandra; Garrido, Susana; Moura, Teresa; Azevedo, Manuela; Figueiredo, Ivone; Instituto Português do Mar e da AtmosferaThe Laboratory of Sclerochronology and the age and growth studies of fishing resources A brief description of the growth studies developed by IPMA, I.P. is given in this report, with emphasis on the halieutic species currently studied both within the scope of the National Programme of Biological Sampling (under the EU/DG Fisheries’ Data Collection Framework (DCF)) as of other research projects and research lines of interest for the Institute. With the aim of disseminating the importance of the multiple growth studies and of their application to improve the knowledge on the biology and dynamics of the commercially exploited species, a summary of the techniques and methodologies applied in the Laboratory of eclerochronology is included.
