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

open access: yesLife, 2022
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]

open access: yesBiology, 2023
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]

open access: yesScientia Marina, 2018
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]

open access: yesFishes, 2022
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]

open access: yesScientia Marina, 2018
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]

open access: yesFoods, 2020
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]

open access: yesFoods, 2020
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.

Preliminary data on Trachurus picturatus (Bowdich 1825) phylogeography inferred from mitochondrial DNA sequence data

open access: yesFrontiers in Marine Science, 2015
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 ...

Endoparasites of Trachurus picturatus (Pisces: Carangidae) from the Madeira and Canary Islands: Selecting parasites for use as tags

open access: yesScientia Marina, 2013
In order to evaluate the use of parasites as biological tags to identify populations of the oceanic horse mackerel, Trachurus picturatus, two samples of 100 fish each, caught off the Madeira and Canary Islands from January to June 2009, were examined for
