ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

We measured a positive linear relationship between eDNA concentration and abundance for larval Delta Smelt (Hypomesus transpacificus) with N = 1 larva exceeding the limit of detection for the novel qPCR assay. Field experiments quantified the probability of detection for eDNA sampling methods at known abundances and distances from source. ABSTRACT Rare

Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.

ABSTRACT Spatio‐temporal species distribution models (SDMs) are valuable tools to support fisheries management, as they account for long‐term and time‐varying unmeasured variation (spatial and spatio‐temporal variation), thereby providing more accurate and statistically efficient estimates than simpler SDMs.

ABSTRACT Statistical distributions of spatial abundance data of animal populations can be informative about underlying processes and mechanisms that govern the spatial distributions. Here, we examine a large data set from annual 0‐group fish surveys in the Barents Sea (1980–2017) collected with standardised trawl sampling from a regular grid with 30–35

ABSTRACT Understanding how low salinity gradients (0‰–5‰) influence fish life cycles is critical for clarifying principles of fish assemblage formation in estuarine ecosystems. This study is intended to provide a foundation for predicting changes in fish populations amidst ongoing surface salinity decreases in the Baltic Sea. In the Neva River Estuary,

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 ...

The Length–Weight Relationships of 17 Freshwater Fishes Inhabiting Bosten Lake, China
Bosten Lake is an important inland freshwater lake in China, which is rich in fishery resources. However, due to various factors, its fishery resources have declined. The length–weight relationship (LWR) is of great significance for fish research and fishery management. This study was based on the samples of 17 freshwater fish species collected from 10
