Review of investigation on the feeding of the European grayling [Translation from: Flora Slodkowodna Polski. Tom 2. Cyanophyta, Glaucophyta (ed. K. Starmach) p350-352. Warsaw, Polska Academia Nauk, 1966] [PDF]

, 1981
The composition of the food of the European grayling and the character of its feeding has been studied fully enough, but this knowledge is scattered in the literature and often contradictory.

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

Journal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

Journal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Effects of Ocean Acidification and Summer Thermal Stress on the Physiology and Growth of the Atlantic Surfclam (Spisula solidissima)

Journal of Marine Science and Engineering
This study examines the physiological response of the Atlantic surfclam (Spisula solidissima) to ocean acidification in warm summer temperatures. Working with ambient seawater, this experiment manipulated pH conditions while maintaining natural diel ...

Endocrine‐Nutritional Synergy Between Sex Inversion and Microencapsulated Bioactives Enhances Growth, Intestinal Development, and Oxidative Stability in Nile Tilapia Larvae

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the combined effects of sex inversion and microencapsulated supplementation with organic acids and essential oils on growth performance, tissue morphology, gene expression, and oxidative status in Nile tilapia (Oreochromis niloticus) larvae.

Year‐round colony‐level differences in foraging behaviour and diel activity of yellow‐legged gulls from natural and urban colonies

Journal of Zoology, EarlyView.
GPS‐tracked yellow‐legged gulls from urban (Porto) and natural (Berlenga) colonies showed contrasting foraging strategies. Urban gulls remained near cities and followed human routines, while natural gulls foraged farther and used marine habitats. Abstract Urbanisation has led to increased populations of opportunistic species like gulls, driven by the ...

Effects of flooding regime and diel cycle on diet of a small sized fish associated to macrophytes Efeitos do regime hidrológico e do ciclo diário na dieta de uma espécie de pequeno porte associada à macrófitas

Acta Limnologica Brasiliensia, 2012
AIM: In this paper we assessed the effects of flooding (low and high water period) on the feeding activity and diet composition of Serrapinus notomelas in patches of the macrophyte Eichhornia azurea in a shallow floodplain lake (upper Paraná River ...
