Abstract

CISTERNA, Lilian  and  ARANCIBIA, Hugo. Age of Jack mackerel Trachrus murphyi (Carangidae) using daily growth rings in sagittae otoliths. Gayana (Concepc.) [online]. 2017, vol.81, n.1, pp.28-31. ISSN 0717-652X.  http://dx.doi.org/10.4067/S0717-65382017000100028.

Growth of Jack mackerel (Trachurus murphyi) was estimated using daily growth rings in fish collected in central-south Chile from 2004 to 2011. The von Bertalanffy growth curve at length for both sexes (n=210 individuals) is FLt = 75*[1-e -0.16( t +0.13)] where FLt is fork length (cm) at time t (years).

Keywords : age; Chile; daily growth rings; Jack mackerel; sagittae otoliths; Trachurus murphyi.
