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.

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.

Seasonal foods, gonadal maturation, and length-weight relationships for nine fishes commonly captured by shrimp trawl on the Northwest Gulf of Mexico Continental Shelf [PDF]

open access: yes, 2008
Recent emphasis on ecosystem approaches to fisheries management renews interest in, and the need for, trophic information about fish communities. A program was started in 1980 at the National Marine Fisheries Service Galveston Laboratory to develop a ...

Farming-up coastal fish assemblages through a massive aquaculture escape event [PDF]

open access: yes, 2014
We investigated the changes on the mean trophic level of fish assemblages across different spatiotemporal scales, before and after a massive escape event occurred off La Palma (Canary Islands), which resulted in the release of 1.5 million fish (mostly ...

Low retention of restocked laboratory‐reared long‐spined sea urchins Diadema antillarum due to Spanish hogfish Bodianus rufus predation

open access: yesRestoration Ecology, Volume 32, Issue 8, November 2024.
The die‐off of the long‐spined sea urchin Diadema antillarum in the 1980s highlighted its crucial role as a primary grazer in tropical western Atlantic coral reefs. However, natural recovery has been slow, exacerbated by a new die‐off in 2022. Interest in actively restoring D.
