The VPA method has been used in assessing the Atlantic horse mackerel
stock. The results indicated a normal explicitation pattern, with 
predominance in the last years of fishes older than 2 years old. The
size of the recruited stock, both in therms of numbers and weight
increased in the last five years. The biomass had a same continuously
increasing tendence from 1976 till to 1980. From our assessment the
horse mackerel stock size in 1981 will be to about 3.3 mil.tons.
