Although ariid catfishe species are known to use coastal systems during some stages of their life cycles, the energetic contribution of estuarine resources and habitat use by many species in this family are still unclear. We used stable isotope analyses to estimate the assimilation of primary carbon sources and to infer the use of estuarine and freshwater habitats by two ariid catfishes Genidens barbus (Lacepede, 1803) and Genidens genidens (Cuvier, 1829). An isotopic mixing model revealed that…

Ontogenetic niche feeding partitioning in juvenile of white sea catfish Genidens barbus in estuarine environments, southern Brazil
Cluster analysis revealed that white sea catfish juvenile populations in the three estuaries are composed of two feeding groups, coincident with a bimodal size–age distribution of the juveniles of white seaCatfish.
Estuary hydrogeomorphology affects carbon sources supporting aquatic consumers within and among ecological guilds
The relative importance of carbon sources supporting aquatic food webs within and among estuaries may be influenced by factors that affect relative availability of autotrophic carbon sources, as well
Estuarine recruitment of a marine goby reconstructed with an isotopic clock
This study shows that the use of an isotopic clock strongly complements catch data and is useful to describe the connectivity between populations and suggests that estuarine residence is caused by trade-offs made at the individual level, whereby migration is probably triggered by temperature.
Flux by fin: fish-mediated carbon and nutrient flux in the northeastern Gulf of Mexico
This study utilized stable isotopes to track seagrass-derived production into offshore food webs in the northeastern Gulf of Mexico and found that gag grouper on reefs as far as 90 km from the segrass beds incorporate a significant portion of seagRass- derived biomass.
Ecosystem Services Transcend Boundaries: Estuaries Provide Resource Subsidies and Influence Functional Diversity in Coastal Benthic Communities
This study demonstrated that the locations where ecosystem services like productivity are generated are not necessarily where the services are utilized, and highlighted the importance of integrative ecosystem-based management that maintains the connectivity of estuarine and coastal ecosystems.
Reproductive biology of two marine catfishes (Siluriformes, Ariidae) in the Sepetiba Bay, Brazil.
Low fecundity and separation in spawning period suggest that both species are k-strategist, able to avoid interspecific competition in early stages of life cycle to optimize the use of the available niche.
Marine nutrient contributions to freshwater apex predators
It is demonstrated that anadromous fish may be a significant source of nutrients to tidal freshwater apex predators through their contribution to diets of large, non-indigenous piscivorous catfish.
