The frequency of microincrement formation in sagittae otoliths of jack mackerel Trachurus symmetricus was validated using experiments on captive fish. Adult jack mackerel were injected with a dose of 100 mg of oxytetracycline/kg of fish.

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.

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 ...

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

BACTERIAL FORMATION OF HISTAMINE IN JACK MACKEREL (TRACHURUS SYMMETRICUS)
Peak histamine concentrations of 0.023, 0.031 and 0.027 g histamine/ 100 g muscle and maximal bacteria concentrations of 1.75, 1.59 and 0.423 g dry cells/100 g muscle were observed in muscles of jack mackerel stored at 25, 15 and 5C, respectively. Incubated fish homogenates suggest rate and transport limitations in histamine formation in muscle.
