Growth Parameters and Mortality Rates Estimated for Seven Data-Deficient Fishes from the Azores Based on Length-Frequency Data.

Given the scarcity of information suitable for stock assessments, the growth and mortality of seven exploited marine fishes in Azorean waters were estimated based on length-frequency data. The studied species were , , , , , spp. and .

Demographics and Yield-Per-Recruit Assessment of the Vulnerable Spiny Lobster in the Azores-Implications for Conservation and Fisheries Management.

The spiny lobster has been intensively harvested across its range and is generally considered overfished, with global landings declining sharply from an average of 820 t in 1960-79 to 385 t in 2000-19. Despite its economic and ecological importance, limited information is available to perform stock assessments and make robust management decisions. In this study, demographics and exploitation levels of were determined from coastal areas of the Azores, and the relevance of these data for conservation planning was discussed.

Biological Knowledge of Thornback Ray () from the Azores: Improving Scientific Information for the Effectiveness of Species-Specific Management Measures.

Elasmobranchs are globally recognized as vulnerable due to their life-history characteristics, fishing pressure, and habitat degradation. Among the skates and rays caught by commercial fisheries, the thornback ray is one of the most economically important in Northwest European seas. However, the scarcity of biological knowledge about this species in Azorean waters has limited the stock assessment types that can be conducted.

Contributions to Management Strategies in the NE Atlantic Regarding the Life History and Population Structure of a Key Deep-Sea Fish ().

With the commercial fishery expansion to deeper waters, some vulnerable deep-sea species have been increasingly captured. To reduce the fishing impacts on these species, exploitation and management must be based on detailed and precise information about their biology. The common mora has become the main deep-sea species caught by longliners in the Northeast Atlantic at depths between 600 and 1200 m.

Can we consider the stocks of alfonsinos Beryx splendens and Beryx decadactylus from the Azores a discrete fishery management unit?

This paper summarises the detailed information on catch, fork length, weight, sex and maturity of alfonsinos Beryx splendens and Beryx decadactylus collected from targeted surveys in Azores waters, complemented by fishery data, over the past c. 20 years. To date, it was not possible to define if the Azorean component of the population can be considered as a discrete local management unit.
