The use of parasites as biological tags for stock identification of blue jack mackerel, Trachurus picturatus, in the northeastern Atlantic waters

Frontiers in Marine Science, 2016
The use of parasites as biological tags for discriminating stocks of blue jack mackerel, Trachurus picturatus (Osteichthyes, Carangidae), in the northeast Atlantic Ocean is assessed herein. In this study the following parasites have been selected as possible biological tags: roundworms Anisakis spp.

Age and growth of the blue jack mackerel, Trachurus picturatus Bowdich, 1825 (Pisces: Teleostei) off Madeira archipelago. [PDF]

, 2006
Between 1984 and 1986, 630 pairs of sagitta otoliths were collected to determine the age and growth of the blue jack mackerel, Trachurus picturatus from Madeiran waters.

Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors. [PDF]

Ecol Evol
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

Development of species‐specific multiplex real‐time PCR assays for tracing the small pelagic fishes of North Pacific with environmental DNA

Environmental DNA, 2022
Environmental DNA (eDNA) has become a popular non‐invasive method to study the presence of organisms in the environment. To study the ecological behavior and migration routes of small pelagic fishes that are difficult to trace with traditional capturing ...

Assessment of a Social Media-Based Method for Determining Raptor Diet. [PDF]

Ecol Evol
This study mined social media as a citizen science method to reduce the time burden and biases associated with recording accurate diet information for predators. In total, 1985 prey observations were recorded of two Australian coastal raptors and were used to produce diet profiles that were compared by region, social media platform, and against other ...

Complementary Role of Fishers’ Experiential Knowledge to Conventional Science in Terms of Species-Specific Biological Traits and Population Changes in Azorean Waters

Biology, 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 ...

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

Frontiers 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 ...
