Morphological covariates of the ontogenetic shift from nauplii to copepodite prey in larval fish. [PDF]

J Fish Biol
Abstract Larval fish are active planktonic predators, with many species feeding initially on copepod nauplii and gradually shifting their selection to copepodites. This study evaluated whether it is possible to develop a general widely applicable empirical model to describe the transition from feeding on copepod nauplii to copepodites in relation to ...

Utilizing Environmental DNA Metabarcoding to Assess Fish‐Based Food Resources in Key Foraging Areas of the Black Stork [PDF]

Ecol Evol
This study employed environmental DNA (eDNA) to assess fish‐based food resources in key foraging areas of the Black Stork (Ciconia nigra)—Zhanghe Canyon and Qixi River National Wetland Parks in Henan, China. Results show that the main prey in these habitats are fish from the orders Siluriformes, Cypriniformes, and Perciformes, with no significant ...

Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding. [PDF]

Ecol Evol
We analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...

Complete mitochondrial genome sequence and SNPs of the Korean smelt Hypomesus nipponensis (Osmeriformes, Osmeridae) [PDF]

Mitochondrial DNA. Part B. Resources, 2019
In this study, the mitogenomes of four smelts (Hypomesus nipponensis) were sequenced and the genomic variation and phylogeny were examined. The mitogenome consisted of 16,782 bp and showed 99.5 ∼ 99.7% sequence similarity with the previously released ...

Evaluating ecosystem caps on fishery yield in the context of climate stress and predation. [PDF]

Ecol Appl
Abstract Ecosystem‐based fisheries management strives to account for species interactions and ecosystem processes in natural resource management and conservation. In this context, ecosystem‐wide caps on total fishery catches have been proposed as one tool to manage multispecies fisheries with an ecosystem approach.

Haemobaphes disphaerocephalus sp.n. (Copepoda : Lernaeoceridae) from the gill cavity of Thaleichthys pacificus (Richardson, 1836) (Osmeridae) [PDF]

Acta Ichthyologica et Piscatoria, 1976
A description of a new parasitic copepod species, Haemobaphes disphaerocephalus sp.n., of the family Lernaeoceridae is presented. The parasite lives in the gill cavity of Thaleichthys pacificus (Rich.) (Osmeridae), which occurs over the Oregon-Washington

Modelling fishing-induced evolution in pikeperch (Sander lucioperca) and vendace (Coregonus albula), Lake Oulujärvi, as template for ecosystem model. [PDF]

J Fish Biol
Abstract Fishing‐induced evolution can impact fish trait distributions, with previous studies highlighting declines in size and age at maturation. However, the effects on fish growth remain less understood, and different fishing methods may exert distinct selection pressures on populations.

A Y-linked anti-Müllerian hormone type-II receptor is the sex-determining gene in ayu, Plecoglossus altivelis.

PLoS Genetics, 2021
Whole-genome duplication and genome compaction are thought to have played important roles in teleost fish evolution. Ayu (or sweetfish), Plecoglossus altivelis, belongs to the superorder Stomiati, order Osmeriformes.
