Vertebrate Coprolites Reveal Diversity of Prey Fishes in the Oligocene Carpathian Basin of the Paratethys

Diversity
Coprolites from the Oligocene Menilite Formation of the Outer Carpathians in southeastern Poland were investigated to reveal the diversity of prey fishes consumed by coprolite producers. The material comprises 186 coprolites from seven localities.

Evolution of Hemoglobin Genes in Codfishes Influenced by Ocean Depth

Scientific Reports, 2017
Understanding the genetic basis of adaptation is one of the main enigmas of evolutionary biology. Among vertebrates, hemoglobin has been well documented as a key trait for adaptation to different environments. Here, we investigate the role of hemoglobins

Genetic homogeneity in the deep-sea grenadier Macrourus berglax across the North Atlantic Ocean [PDF]

, 2018
Paucity of data on population structure and connectivity in deep sea species remains a major obstacle to their sustainable management and conservation in the face of ever increasing fisheries pressure and other forms of impacts on deep sea ecosystems ...

Large-scale Phylogenomic Analysis Provides New Insights Into the Phylogeny of the Order Gadiformes and Evolution of Freshwater Gadiform Species Burbot (Lota lota)

, 2021
Our understanding of phylogenetic relationships among Gadiformes fish is obtained through the analysis of a small number of genes, but uncertainty remains around critical nodes. A series of phylogenetic controversial exists at the suborder, family, subfamily, and species levels.

Food composition and prey selection of cod, Gadus morhua (Actinopterygii: Gadiformes: Gadidae), in the southern Baltic Sea [PDF]

Acta Ichthyologica et Piscatoria, 2013
Background. At the end of 1980s, ecological regime shifts occurred in the Baltic. Since, the Baltic fish assemblage has been dominated by sprats, whereas before cod was the dominant fish species.

Performance of eDNA Filtration Methods for Monitoring Fish Diversity in a Hyper‐Tidal Estuary

Environmental DNA, Volume 7, Issue 5, September–October 2025.
This study evaluates four eDNA filtering methods, three manual filters (0.45, 1.2, and 5 μm) and a passive method, the metaprobe, across a salinity gradient in a hyper‐tidal estuarine ecosystem. Results show that the 0.45 μm filter detected the highest species richness (39 species), followed by the metaprobe (35 species), and the 1.2 μm (34 species ...

Reproduction of Baltic cod, Gadus morhua (Actinopterygii: Gadiformes: Gadidae), in the Gotland Basin: Causes of annual variability [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. The Gotland Basin spawning ground is one of three main spawning areas of Baltic cod, Gadus morhua Linnaeus, 1758. The threshold water parameters for cod development are the salinity exceeding 11‰ and the oxygen level above 2 mL&#

Estimating Time‐Varying Productivity and Reference Points: A Case of North Sea Demersal Fish Stocks

Fish and Fisheries, Volume 26, Issue 5, Page 745-771, September 2025.
ABSTRACT The productivity of marine fish populations determines both maximum sustainable yield (MSY) and resilience to exploitation. While biological reference points like MSY and BMSY depend on species traits and population density, they are also influenced by environmental variability and ecological interactions.
