Using fish eDNA metabarcoding, we successfully described an overwintering fish community in ice‐covered environments. eDNA data indicated that the dominant species were Clupea pallasii in the lagoon and Tribolodon spp. in the inlet river. Our findings suggested that the eDNA technique is useful for studying ice‐covered areas and could provide new ...

ABSTRACT Pikeperch (Sander Lucioperca) belongs to main predatory fish species in freshwater bodies throughout Europe playing the key role by reducing planktivorous fish abundance. Two size classes of the young‐of‐the‐year (YOY) pikeperch are known in Europe and North America.

Seasonal stability in parasite assemblages of the Brazilian flathead, Percophis brasiliensis (Perciformes: Percophidae): Predictable tools for stock identification [PDF]
A comparison of the composition and structure of parasite communities of the Brazilian flathead, Percophis brasiliensis Quoy et Gaimard (Perciformes: Percophidae) among seasons during one year was carried out in the Argentine Sea.

Using two datasets with multiple decades of data, we find that larval fish in the northeast Pacific are, on average, appearing earlier in the year over time. These shifts can be partially explained by shifts in the seasonality of ocean temperature, upwelling, and prey abundance.

The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

Larval development of the Mexican Snook, Centropomus poeyi (Teleostei: Centropomidae)
We document for the first time the early ontogeny of Centropomus poeyi based on captive raised material representing 0-19 days posthatch (dph). The achievement of early developmental landmarks (i.e., yolk-sac depletion, flexion, development of fins) and ...

Abstract Marine fish communities are highly diverse and contribute significantly to ecosystem processes. However, understanding their specific functional roles and the importance of different prey groups for sustaining fish communities has been limited by the historical classification of fishes into a few coarse trophic guilds.
