A Comparison of the Innate and Adaptive Immune Systems in Cartilaginous Fish, Ray-Finned Fish, and Lobe-Finned Fish

open access: yesFrontiers in Immunology, 2019
The immune system is composed of two subsystems—the innate immune system and the adaptive immune system. The innate immune system is the first to respond to pathogens and does not retain memory of previous responses.

Complete mitogenomes of five ecologically diverse Australian freshwater fishes

open access: yesMitochondrial DNA. Part B. Resources, 2019
Complete mitochondrial genome sequences were determined for five species of Australian freshwater fishes, representing a diverse range of ecologies and life histories. Mitogenomes were sequenced and annotated for Craterocephalus stramineus (Atherinidae);

The evolution, structure and function of the ray finned fish (Actinopterygii) glucocorticoid receptors [PDF]

open access: yesGeneral and Comparative Endocrinology, 2017
Basal ray-finned fish (Actinopterygii) possess a single glucocorticoid receptor (GR) and when compared to the lobe-finned vertebrate (Sarcopterygii) GR possess nine additional amino acids between the zinc-finger of the DNA binding domain. A whole genome duplication event which occurred between 320 and 350MYA in the teleost lineage following the split ...

DNA barcoding of the fishes of the genus Alburnoides (Actinopterygii, Cyprinidae) from Caucasus

open access: yesMitochondrial DNA Part A, 2016
Spirlins of the genus Alburnoides are widespread fishes, which taxonomy has been rapidly developing in recent years. Mitochondrial cytochrome c oxidase subunit I (COI) was used as DNA barcode marker to create a reference dataset of Caucasian Alburnoides and to test its barcoding efficiency.

Length-weight relationship of 73 fish species caught in the southeastern inner continental shelf region of Brazil

open access: yesLatin American Journal of Aquatic Research, 2014
The a and b parameters of the length-weight relationship (LWR) of the form W = aLb were estimated for 71 species of Actinopterygii and 2 Elasmobranchii, caught in the coastal region and inner shelf of southeastern Brazil. Estimates of b varied from 2.151
