Growth Parameters and Mortality Rates Estimated for Seven Data-Deficient Fishes from the Azores Based on Length-Frequency Data [PDF]
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 Trachurus picturatus, Sparisoma cretense,

Complementary Role of Fishers’ Experiential Knowledge to Conventional Science in Terms of Species-Specific Biological Traits and Population Changes in Azorean Waters [PDF]
Combining scientific information with fishers’ perceptions may be a robust approach for directing decision-makers working with marine ecosystems. This is particularly the case when baseline data on a vulnerable stock are poor, as the integration of ...

Reconstructing discards profiles of unreported catches [PDF]
In Portugal it has been estimated that unreported catches represent one third of total catches. Herein, information on landings and total unreported catches (discards) by commercial métier were disaggregated into high taxonomic detail using published ...

Modelling Fish Growth with Imperfect Data: The Case of Trachurus picturatus [PDF]
Growth modelling is essential to inform fisheries management but is often hampered by sampling biases and imperfect data. Additional methods such as interpolating data through back-calculation may be used to account for sampling bias but are often ...

By-catch species susceptibilities and potential for survival in Algarve (southern Portugal) deep-water crustacean trawl fishery [PDF]
Bottom trawling for crustaceans in Portuguese coastal waters is an important fishery in terms of revenue, despite its negative impacts on deep-sea ecosystems.

Seasonal Sensory Evaluation of Low Commercial Value or Unexploited Fish Species from the Portuguese Coast [PDF]
Overfishing is increasing over time, and according to FAO (Food and Agriculture Organization), about one third of the world’s fish stocks are now overfished.

Adding Value to Bycatch Fish Species Captured in the Portuguese Coast—Development of New Food Products [PDF]
We live in a world of limited biological resources and ecosystems, which are essential to feed people. Consequently, diversifying target species and considering full exploitation are essential for fishery sustainability.

The populations of marine pelagic fishes, in particular the migratory ones as the Trachurus picturatus (Bowdich 1825), may be erroneously considered an homogenous population unit because they show broad geographic distributions, large population sizes ...
