Silva, Cristina; Azevedo, Manuela; Chaves, Corina; Coelho, Rui; Costa, Ana Maria; Dinis, David; Dores, Sandra; Fernandes, Ana Cláudia; Gonçalves, Patrícia; Lino, Pedro G.; Mendes, Hugo; Moura, Teresa; Nunes, Cristina; Oroszlányová, Melinda; Silva, Daniel Pinto Maria do Carmo; Instituto Português do Mar e da Atmosfera, I.P.The Workshop on Sampling Effort for Biological Parameters (WKSEBP), chaired by Manuela Azevedo and Cristina Silva (IPMA) met in Lisbon, 18 – 20 November 2017, to focus on the analysis of the current Portuguese sampling designs under PNAB/DCF (Programa Nacional de Amostragem Biológica/Data Collection Framework) with the aim to optimize the sampling effort and improve precision on the estimation of biological parameters. Several approaches and methodologies were discussed and guidelines for future work were recommended. Four case-studies were analyzed focusing on: 1) survey sampling for length, 2) atmarket sampling for length, 3) estimation of age-length key and 4) maturity ogive. The number of samples, the effective sample size and the precision in parameters estimation were discussed in each case-study.
