Inclusion Impact of Jack Mackerel Meal in the Red Sea Bream (Pagrus major) Feeds Replacing Various Animal Protein Sources for Fish Meal [PDF]

open access: yesAquaculture Nutrition
This study aims to elucidate manipulation impacts of jack mackerel meal (JMM) in the red sea bream (Pagrus major) feeds replacing various animal protein sources for different levels of fish meal (FM) on growth and feed availability.

Results of the jack mackerel subpopulation discrimination feasibility study [PDF]

open access: yes, 1976
A report is made on the feasibility of discriminating subpopulations of jack mackerel, Trachurus symmetricus, off of the southern California and Baja California coast. Histochemical, morphometric, and meristic characters are compared from four samples of approximately 200 fish each taken from three areas.

Effects of Replacing Fish Meal With Plant Protein Sources in Diets With or Without Jack Mackerel Meal Inclusion on Growth Performance of Red Sea Bream (<i>Pagrus major</i>). [PDF]

open access: yesAquac Nutr
Due to stagnant production and high cost of fish meal (FM), feed nutritionists are seeking reliable and affordable alternatives. However, low‐FM diets often result in poor palatability, reduced feed consumption (FC), and impaired growth. This study investigates the effects of replacing FM with plant proteins in diets with or without jack mackerel meal (

Fishing Location decisions in the Chilean-Transzonal Jack Mackerel Fishery [PDF]

open access: yes, 2008
This study examines factors conditioning the fishing location decisions of the Chilean fleet operating in the South-east Pacific straddling jack mackerel fishery, considering voyage data for the1987-2004 period. As from the early 1990s, this fleet began to move beyond the 200 nm zone, responding to changes in the spatial distribution of the species. It

Complete Mitochondrial Genome of the Araucanian Herring, <i>Strangomera bentincki</i>, Norman, 1936 (Teleostei: Clupeiformes: Clupeidae): Phylogenetic Analysis and Implications in Fishmeal Traceability. [PDF]

open access: yesEcol Evol
Araucanian herring (Strangomera bentincki) is a pelagic fish whose main processed products are fishmeal and oil. The complete mitogenome is 16,758 bp, consisting of 13 coding genes, two rRNAs, 22 tRNAs, and the control region. Phylogenetic analysis supported a monophyletic clade with Sprattus muelleri and Sprattus antipodum.

Accuracy of the Kirchhoff-approximation and Kirchhoff-ray-mode fish swimbladder acoustic scattering models. [PDF]

open access: yesPLoS ONE, 2013
The acoustic backscatter from pressure release prolate spheroids and a three-dimensional representation of a fish swimbladder (Chilean jack mackerel, Trachurus symmetricus murphyi) was calculated using four target strength models (Kirchhoff-approximation,
