Sousa, R.; Pinho, M. R.; Delgado, J.; Pinto, A. R.; Biscoito, M.; Dellinger, T.; Henriques, P.Analysis of abundance and population structure of Plesionika narval was performed on data concerning 5,255 specimens obtained from 62 fishing sets carried out off the Madeira archipelago (Northeastern Atlantic) between 2004 and 2008 in a depth range from 101 to 350 m.

Sousa, R.; Pinho, M. R.; Delgado, J.; Biscoito, M.; Pinto, A. R.; Dellinger, Thomas; Gouveia, L.; Carvalho, D.; Henriques, P.Several experimental surveys were carried out in the Northeastern Atlantic, Madeira archipelago from 1991 to 2008 to explore new fisheries resources. This study examined the selectivity of bottom and floating traps and the analysis of yield-per-recruit (YPR) and biomass-per-recruit (BPR) providing helpful insight to the management of the shrimp Plesionika narval. A total of 28,262 specimens were sampled and the...

Abecasis, D.; Costa, A. R.; Pereira, J. G.; Pinho, M. R.The age and growth of the Helicolenus dactylopterus (Delaroche, 1809) in the Azorean waters were studied using whole and sliced otolith readings. Individuals were collected during demersal surveys carried out around the Azores islands and its most important fishing banks and also from commercial landings. A total of 1024 individuals were measured, weighed and their sex was determined. Individuals ranged from 3 ...
