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

Marine 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.

Mitochondrial DNA population structure in white mouth croaker (Micropogonias furnieri) along the atlantic coast of Brazil. [PDF]

, 2004
Variation in mitochondrial DNA (mtDNA) was examined among 149 white mouth croakers (Micropogonias furnieri) from six geographic locations in the Atlantic coast of Brazil (1° S - 340 S).

Hyperostosis in Fishes: An Update With New Species Records

Journal 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.

Cannibalism on planktonic eggs by a non-filter feeding fish, Micropogonias furnieri (Sciaenidae)

Fisheries Research, 2002
Cannibalism by fishes on planktonic eggs is typical of filter-feeding marine planktivores, i.e. fishes that have the ability for filtering large volumes of water and concentrate small food particles. We report an unusual case of cannibalism on planktonic eggs by adults of the non-filter feeding fish Micropogonias furnieri, which are opportunistic ...

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Update of the risk assessment of brominated phenols and their derivatives in food

EFSA Journal, Volume 22, Issue 10, October 2024.
Abstract The European Commission asked EFSA to update its 2012 risk assessment on brominated phenols and their derivatives in food, focusing on five bromophenols and one derivative: 2,4,6‐tribromophenol (2,4,6‐TBP), 2,4‐dibromophenol (2,4‐DBP), 4‐bromophenol (4‐BP), 2,6‐dibromophenol (2,6‐DBP), tetrabrominated bisphenol S (TBBPS), tetrabromobisphenol S

Gillnet selectivity for whitemouth croaker (Micropogonias furnieri) from southeastern and southern Brazil

Latin American Journal of Aquatic Research, 2016
The whitemouth croaker is one of the most important demersal resources of southeast and southern Brazil, and it is caught mostly by bottom gillnets. This fishing system has the advantage of a unimodal distribution of size selectivity, where the optimum length corresponds to the mode of the distribution.
