Rhadinorhynchus oligospinosus n. sp. (Acanthocephala, Rhadinorhynchidae) from mackerels in the Pacific Ocean off Peru and related rhadinorhynchids in the Pacific, with notes on metal analysis [PDF]
Specimens of a new species of Rhadinorhynchus Lühe, 1911 are described from the chub mackerel Scomber japonicus (Scombridae) and the Chilean Jack mackerel Trachurus murphyi (Carangidae) (possibly a subspecies of Trachurus symmetricus) from the Pacific ...

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

The jack mackerel (Trachurus symmetricus) resource of the eastern North Pacific [PDF]
The jack mackerel before 1947, was of minor commercial importance having to take a back seat to the better known, more profitable, and more abundant Pacific sardine (Sardinops caeruleus) and the more desirable Pacificmackerel (Scomber japonicus). During these years it was referred to as "horse mackerel" and had relatively little market appeal.

Dinámica trófica del jurel (Trachurus symmetricus murphyi) en el norte de Chile [PDF]
The trophic dynamic of jack mackerel Trachurus symmetricus murphyi, caught off the coast of northern Chile, between the spring 1993 and winter 1994, is described. Relative importance of prey taxa, identification of ontogenetic trophic units and prey selectivity by size was evaluated.

Precisión en los estimados de distribución de frecuencias de tallas de jurel, Trachurus symmetricus [PDF]
In central-south Chile, the jack mackerel (Trachurus symmetricus) resource conforms disperse aggregations in a reproductive condition in oceanic waters, and obtaining representative samples to estimate populational attributes as size composition and mean size is difficult. In this paper, the precision of these attributes was analyzed through resampling
