Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

open access: yesJournal of Fish Biology, EarlyView.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

Trophic niche overlap between native and non‐native fishes in central Anatolian lakes, Türkiye

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Central Anatolian region of Türkiye exhibits exceptionally high freshwater fish diversity and endemism and is increasingly exposed to the introduction of non‐native taxa. We examined the diet composition, prey selectivity and interspecific dietary overlap among eight native and five non‐native fish species across seven lakes in Central ...

Fishing areas characterisation using the SIMOcean platform

open access: yesAquatic Living Resources, 2017
In this study, the relationships between sea surface temperature (SST), chlorophyll-a (Chl-a) concentration and catch locations of sardine (Sardina pilchardus) and Atlantic chub mackerel (Scomber colias) were explored using satellite-derived SST and Chl ...

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management

open access: yesFish and Fisheries, Volume 27, Issue 5, Page 1134-1150, September 2026.
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.

Introgressive hybridization erodes morphological divergence between lentic and lotic habitats in an endangered minnow

open access: yesEcology and Evolution, 2021
Introgressive hybridization may erode phenotypic divergence along environmental gradients, collapsing locally adapted populations into a hybrid swarm. Alternatively, introgression may promote phenotypic divergence by providing variation on which natural ...
