The Vertebral Column of Flatfish: A Review

open access: yesReviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Flatfish (Pleuronectiformes) encompass fascinating fish species known for their high gastronomical value, rearing performances, and market prices, which attract both economic and scientific interest. Despite these attributes, flatfish exhibit unique morphological, developmental, and biological features, as well as distinctive swimming ...

Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

open access: yesDevelopmental Dynamics, Volume 254, Issue 8, Page 887-901, August 2025.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Stock assessment and exploitation of Atlantic salmon Salmo salar L. in the river Drammenselv

open access: yesFauna Norvegica, 1986
In 1985 the total salmon run and the exploitation rate in the river Drammenselv were estimated by combining catch statistics, counts of ascending salmon in a salmon ladder at Hellefoss, and a tagging-recapture experiment of the spawning stock below the ...

Temporal and Spatial Dynamics of Surface Water Temperature Changes in China's Major Lakes

open access: yesWater Resources Research, Volume 61, Issue 7, July 2025.
Abstract Globally the lake surface water temperature (LSWT) has shown an upward trend and exhibits significant spatial heterogeneity, but previous studies have indeed delved it under current period. Here, we investigated the characteristics of LSWT variation in major lakes of China over two centuries.

Growth, migration and survival of lake reared juvenile anadromous Atlantic salmon Salmo salar L.

open access: yesFauna Norvegica, 1987
A release of 16.741 underyearlings of Atlantic salmon Salmo salar in Lake Storevatnet in the River Imsa system resulted in a downstream migration of 1.580 smolts. Most of the smolts were 2 years of age, but there was also a significant proportion of one
