DNA barcoding of marine rocky reef fishes from northern Peru suggests a parapatric speciation in the Tropical Eastern Pacific

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
Using a DNA barcoding technique we found evidence that reinforce the hypotheses of how parapatric speciation could drive the origin of new species in the TEP. Abstract Northern Peru marks the end of an extensive coastal marine region: The Panama province, which is characterized by predominantly tropical and equatorial features and is home to the only ...

Health risk of consuming Sphoeroides spp. from the Navachiste Lagoon complex due to its trace metals and organochlorine pesticides content

open access: yesScientific Reports, 2022
The Navachiste complex (NAV) is impacted by neighbored human activities and is located in the southwestern coastal zone of the Gulf of California. The study determines the trace metal (TM) and organochlorine pesticides (OCP) health risk content in the ...

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).

First Toxicological Analysis of the Pufferfish Sphoeroides pachygaster Collected in Italian Waters (Strait of Sicily): Role of Citizens Science in Monitoring Toxic Marine Species

open access: yesAnimals, 2023
Pufferfish (Tetraodontidae) inhabiting the Mediterranean Sea may represent an emerging public health risk due to the possible accumulation of marine neurotoxins such as tetrodotoxin (TTXs) and saxitoxin (STXs) in their tissues.

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.
