Deep genetic differentiation in the little tunny from the Mediterranean and east Atlantic. [PDF]

open access: yes, 2020
In this study we present the analysis of the stock structure of Little tunny (Euthynnus alletteratus) using the mitochondrial control region as a genetic marker. More than 500 individuals distributed in six locations were analyzed. Samples were from three main regions: Mediterranean (Tunisia and Spain), and northeast Atlantic (Portugal and Senegal) and

Age, growth, and maturity of little tunny, Euthynnus alletteratus (Rafinesque, 1810) in southeastern Brazil

open access: yesLatin American Journal of Aquatic Research, 2021
This is the first attempt to assess life parameters of little tunny Euthynnus alletteratus in the southwestern Atlantic. Fin spines, liver, and gonad information from 345 fishes (330-780 mm fork length) sampled from artisanal landings between March 2018, and February 2019 were used to analyze age, growth, and sexual maturity.

Immunohistochemical Evaluation of Histamine Levels and Hygienic Aspect of Little Tunny (Euthynnus alletteratus) Musculature at Different Environment Time and Temperature

open access: yesJournal of Aquatic Food Product Technology, 2023
We investigated the effect of storage time and temperature on muscular histamine (HIS) contents in little tunny (LT). Fifty LT were preserved at various temperatures (0- 21°C). We collected muscles from several areas at 0-, 6-, 12-, 18-, and 24 h post-fishing for further examination.
