Comparing Aquatic Environmental DNA Collection Methods Across a Diel Cycle in a Lotic System

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Water samples were collected over 25 h from the Tangipahoa River, Louisiana, using active and passive environmental DNA methods to detect fish assemblages. Active sampling involved collecting water samples at hourly intervals for 25 h, whereas passive sampling deployed a stationary filter for 25 h.

Length–Weight Relationships for 22 Mid‐Atlantic Species Show Variability in Slopes Spatially, Temporally, and With Published Regressions

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
Despite their importance in understanding stream food webs and community dynamics, small‐bodied and nongame fish remain relatively understudied. This is also true of the basic ecology for these taxa, such as calculating length–weight relationships (LWRs).

Rapid Decline of Olfactory and Gustatory Receptor Sensitivities of Wild Catfish (Ictaluridae) after Capture

, 1973
In several species of catfish (Ictaluridae), comparably high sensitivities of olfactory and gustatory receptors to α-amino acids as a class were confirmed.

Short-term infection dynamics of the monogenean parasite Ligictaluridus floridanus (Monogenea: Dactylogyridea: Ancyrocephalidae) on channel catfish Ictalurus punctatus (Actinopterygii: Siluriformes: Ictaluridae) [PDF]

Acta Ichthyologica et Piscatoria
Ligictaluridus floridanus (Mueller, 1936) is a monogenean parasite that affects farmed channel catfish, Ictalurus punctatus (Rafinesque, 1818). No studies, however, have been conducted on this monogenean’s infection dynamics. The aim of this study was to

A draft genome of the striped catfish, Pangasianodon hypophthalmus, for comparative analysis of genes relevant to development and a resource for aquaculture improvement

BMC Genomics, 2018
Background The striped catfish, Pangasianodon hypophthalmus, is a freshwater and benthopelagic fish common in the Mekong River delta. Catfish constitute a valuable source of dietary protein. Therefore, they are cultured worldwide, and P. hypophthalmus is

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Effects of Temperature, Air Exposure Time, and Bleeding on Post‐Release Movement of Angled Channel Catfish

Fisheries Management and Ecology, Volume 32, Issue 5, Page 320-329, October 2025.
ABSTRACT Catch‐and‐release angling is an effective conservation tool only when released fish survive. Measuring the physiological response of sportfish to capture has recently been enhanced by the use of accelerometers to measure post‐release movement.

Microstructures of barbels and bony plates of Satyrichthys laticeps (Actinopterygii: Peristediidae)

Journal of Fisheries, 2020
Barbels are sensory-appendage near the mouth of many fishes including Cyprinidae, Ictaluridae and Peristediidae and commonly used for identification of the species.
