Reef Fish Assemblage Through Space and Time in a Thermal Transition Zone in the Southwestern Atlantic

open access: yesDiversity and Distributions, Volume 31, Issue 8, August 2025.
ABSTRACT Aim Assessing the structure of reef fish assemblages and their spatiotemporal changes (β‐diversity) in seven reef locations across a thermal transition zone in the southwestern Atlantic. Location Eastern Brazilian coast, from the northern Abrolhos Bank (17° S; 26.37°C) to the southern Espírito Santo state (20° S; 21.13°C). Methods We used four‐

Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay

open access: yesMarine Ecology, Volume 46, Issue 2, March 2025.
ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.

Habitat selection by fish in an artificial reef in Ilha Grande Bay, Brazil

open access: yesBrazilian Archives of Biology and Technology, 2001
The use of artificial structures as a shelter for fishes was evaluated aiming to assess increase in fish abundance in Ilha Grande Bay at Southeast Brazilian coast (Lat: 22°8'-23°5' S; Long. 44º05’-44º40’W).

Zooplankton in Aquaculture: A Perspective on Nutrition and Cost‐Effectiveness

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Successful aquaculture relies on effective feeding strategies for target species, from the larval stage through to sexually mature adults, in both marine and freshwater environments. Aquatic organisms, particularly larvae, instinctively prefer live feeds like algae and zooplankton; larvae are entirely dependent on live feeds due to their undeveloped ...

Hyperostosis in Fishes: An Update With New Species Records

open access: yesJournal of Morphology, Volume 285, Issue 11, November 2024.
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.
