Management proposal based on the timing of oral incubation of eggs and juveniles in the sentinel species Genidens genidens (Siluriformes: Ariidae) in a tropical estuary [PDF]

open access: yesNeotropical Ichthyology, 2018
Ariids such as Genidens genidens are particularly susceptible to overfishing because of their complex reproductive mechanisms, which result in slow replenishment of stocks.

Sexual dimorphism in the catfish Genidens genidens (Siluriformes: Ariidae) based on otolith morphometry and relative growth [PDF]

open access: yesNeotropical Ichthyology, 2019
Genidens genidens is a species susceptible to population declines in view of their reproductive biology peculiarities. Morphometric differences between sexes are observed in the literature, and these differences should also be evident in otolith ...

Are the Temporal Changes Observed in the Reproductive Biology of the Estuarine Conguito Sea Catfish Related to Increased Small‐Scale Fishing Effort on the Northwestern Pacific Coast of Mexico?

open access: yesMarine and Coastal Fisheries, Volume 14, Issue 4, August 2022., 2022
Abstract Biological parameters relating to the reproductive biology of Conguito Sea Catfish Cathorops liropus were investigated in 1979–1984 and 2015–2018 from an estuarine system on the northwestern Pacific coast of Mexico. In the first period, the spawning season occurred during the dry–warm season (April–June), according with the percentage of ...

Revealing the drivers of taxonomic and functional diversity of nearshore fish assemblages: Implications for conservation priorities

open access: yesDiversity and Distributions, Volume 28, Issue 8, Page 1597-1609, August 2022., 2022
Abstract Aim Understanding patterns and drivers of biodiversity are essential towards developing effective conservation strategies for shallow marine habitats broadly. However, little is known about the natural and anthropogenic factors that structure fish biodiversity of sandy beaches, one of the largest and most socio‐economically valuable nearshore ...

Virulence‐Associated Genes and Antimicrobial Resistance of Aeromonas hydrophila Isolates from Animal, Food, and Human Sources in Brazil

open access: yesBioMed Research International, Volume 2020, Issue 1, 2020., 2020
Aeromonads are natural inhabitants of aquatic environments and may be associated with various human or animal diseases. Its pathogenicity is complex and multifactorial and is associated with many virulence factors. In this study, 110 selected Aeromonas hydrophila isolates isolated from food, animals, and human clinical material from 2010 to 2015 were ...
