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

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,

Trends in abundance indices derived from commercial fisheries for priority marine stocks in the Azores

open access: yesJournal of Fish Biology, Volume 103, Issue 4, Page 815-827, October 2023., 2023
Abstract Large‐scale assessments of fish and shellfish populations may be valuable for identifying the impacts of fishing pressure on stocks, but they are rarely possible due to a lack of long‐term datasets. In this study, a two‐part mixed‐effect model for lognormal data was used to obtain historical abundance indices for 16 priority fish and shellfish

Climate change disrupts core habitats of marine species

open access: yesGlobal Change Biology, Volume 29, Issue 12, Page 3304-3317, June 2023., 2023
Marine species have started to shift their distributions across the global oceans in response to changing climate. Understanding how these changes will affect future marine life is crucial for conservation management and the provision of ecosystem services.

Comparing otolith shape descriptors for population structure inferences in a small pelagic fish, the European sardine Sardina pilchardus (Walbaum, 1792)

open access: yesJournal of Fish Biology, Volume 102, Issue 5, Page 1219-1236, May 2023., 2023
Abstract Otolith shape analysis has been one of the most used approaches to study population structure in the past decades. Currently, two sets of shape descriptors are used to perform otolith shape analysis, namely, Elliptic Fourier descriptor (EFd), which focuses on the overall otolith shape differences, and Discrete Wavelet descriptor (DWd), which ...

Comparison of anisakid infection levels between two species of Atlantic mackerel (Scomber colias and S. scombrus) off the Atlantic Portuguese coast

open access: yesScientia Marina, 2017
Anisakiasis is a problematic zoonotic infection associated with the consumption of raw or undercooked fish. Atlantic mackerel (Scomber colias) is of high commercial interest in Portugal and has been reported as a common host of Anisakisspp. In this study,

Metabarcoding confirms the opportunistic foraging behaviour of Atlantic bluefin tuna and reveals the importance of gelatinous prey [PDF]

open access: yesPeerJ, 2021
Studies of the diet, feeding habits and trophic activity of top marine predators are essential for understanding their trophodynamics. The main direct method used for such studies thus far has been morphological inventories of stomach contents.
