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

open access: yes, 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.

Age, growth and food of the Burbot Lota lota in two eutrophic lakes in southeast

open access: yesFauna Norvegica, 1992
The growth and food of the burbot Lota lota was studied in two neighbouring meso-eutrophic lakes in southeast Norway. The burbot grew slower and reached smaller theoretical maximum lengths in Lake Øgderen than in Lake Rødenes (L∞ = 40.5 cm vs 69.5 cm ...

Maternal effects on recruitment of five gadoid species

open access: yesMarine Ecology, EarlyView.
Abstract Commercial fishing is almost always non‐random and generally removes large and old individuals from fish stocks, thereby reducing age diversity among spawners. Reduced age diversity may result in less stable recruitment. Here, we explore the influence of age diversity (H), mean age of the spawning stock (MA) and sea surface temperature (SST ...

Notes on Norwegian marine Amphipoda 11. Ceradocus torelli (Goes, 1866), a new amphipod for Norway

open access: yesFauna Norvegica, 1990
Several specimens of the circumpolar melitid amphipod Ceradocus torelli (Goes, 1866) were found in stomachs of cod Gadus morhua in Stålvikbotn, N. Norway. These are the first records of this large and spectacular amphipod from Norwegian waters.

The deep-sea teleost cornea: a comparative study of gadiform fishes.

open access: yesHistology and histopathology, 1998
The corneal structure of three deep-sea species of teleosts (Gadiformes, Teleostei) from different depths (250-4000 m) and photic zones are examined at the level of the light and electron microscopes. Each species shows a similar but complex arrangement of layers with a cornea split into dermal and scleral components.

Genomic architecture of haddock (Melanogrammus aeglefinus) shows expansions of innate immune genes and short tandem repeats

open access: yesBMC Genomics, 2018
Background Increased availability of genome assemblies for non-model organisms has resulted in invaluable biological and genomic insight into numerous vertebrates, including teleosts.

FISH OTOLITHS FROM THE LATE MAASTRICHTIAN KEMP CLAY (TEXAS, USA) AND THE EARLY DANIAN CLAYTON FORMATION (ARKANSAS, USA) AND AN ASSESSMENT OF EXTINCTION AND SURVIVAL OF TELEOST LINEAGES ACROSS THE K-PG BOUNDARY BASED ON OTOLITHS

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2020
Otolith assemblages have rarely been studied across the K-Pg boundary. The late Maastrichtian Kemp Clay of northeastern Texas and the Fox Hills Formation of North Dakota, and the early Danian Clayton Formation of Arkansas therefore offer new insights ...

A new fossil from the Eocene of Iran provides new insights regarding the evolution of the morphologically bizarre tube‐eye fish

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Stylephoriformes are a morphologically bizarre lineage of deep‐sea fishes, currently represented by a single extant species, Stylephorus chordatus, the so‐called tube‐eye fish. The phylogenetic relationships of the Stylephoriformes were extensively debated until recent genomic studies proposed a sister‐group relationship with the Gadiformes ...
