R TOOLBOX GUIDELINES FOR AGE READING ANALYSES
Silva, Andreia V.; Soares, EduardoFish otolith age calibration and exchanges are carried out periodically to improve the quality of age data used in age-based stock assessments. These calibrations use online tools for age reading and the statistical analysis are frequently done on Eltink 2000 spreadsheet. With the replacement of this software and Eltink limitations, statistical evaluation was performed using R code. This change has shown clear ...

Accumulation of chemical elements and occurrence of microplastics in small pela...
Silva, Joana M. da; Alves, Luís M.F.; Laranjeiro, Maria I.; Bessa, Filipa; Silva, Andreia V.; Norte, Ana C.; Lemos, Marco F.L.; Ramos, Jaime A.The assessment of contaminant exposure in marine organisms often focuses on the most toxic chemical elements from upper trophic level species. Information on mid-trophic level species and particularly on potentially less harmful elements is lacking. Additionally, microplastics have been considered emergent contaminants in aquatic environments which have not been extensively studied in species from mid-trophic l...
REPORT OF THE WORKSHOP ON MODELLING CATCH-PER-UNIT-EFFORT (WKCPUE)
Coelho, Rui; Fernandes, Ana Cláudia; Mendes, Hugo; Moura, Teresa; Serra-Pereira, Bárbara; Silva, Andreia V.; Silva, Cristina; Azevedo, ManuelaStandardized Catch-Per-Unit-Effort (CPUE), i.e., data from commercial fisheries that have been statistically modelled to remove fishery dependant effect, are often used in stock assessments as indicators of abundance and biomass. Here we report the outcomes of the workshop on modeling CPUEs that took place virtually on the 3-5 November 2020 and 6-7 January 2021 organized by IPMA and integrated in PNAB/DCF (Nati...
