\nIFOP held a national workshop to review and improve horse mackerel stock\u2019s evaluation considering new information generated by our Institution, which shows that horse mackerel has: faster individual growth; higher natural mortality; and earlier maturity.<\/p>\n

The workshop was planned by IFOP and Fisheries and Aquaculture Undersecretariat (SSPA) in preparation for a similar workshop to be held by South Pacific Regional Fisheries Management Organization (OROP-PS) scientific committee in Seattle. The workshop was organized by Ignacio Pay\u00e1, and was attended by SSPA administrators, Technical Scientific Committee members, researchers from IFOP, INPESCA, Universidad de Concepci\u00f3n and P. Universidad Cat\u00f3lica de Valpara\u00edso.<\/p>\n

During the workshop, IFOP\u2019s team (Ignacio Pay\u00e1, Renzo Tascheri and Mauricio Mardones) previously obtained results were analyzed and complementary sensitivity analyzes were carried out. The workshop was carried out with a standard of full transparency, that is, all the data and programs were available to allow the participants to replicate analyzes and to contribute with new analyses.<\/p>\n

The figure shows spawning biomass estimates sensitivity against different data and parameters combinations of estimation model. The series with the highest level corresponds to highest natural mortality scenario.<\/figcaption><\/figure>\n

In all analyzed cases, jack mackerel stock current condition was healthy, with biomass values \u200b\u200bgreater than maximum sustained yield biomass. The most important parameter was natural mortality followed by stock-recruit escapement parameter relationship and maturity at age.<\/p>\n
