'Atlantic mackerel (Scomber scombrus L.) are found in the coastal waters of the Northwest Atlantic from North Carolina to Labrador (Figure 1). They overwinter in deeper warmer waters at the edge of the continental shelf and migrate inshore during the spring to spawn and then disperse to feed. There are two spawning contingents in the Northwest Atlantic. The Northern contingent spawns in Canadian waters primarily in the Southern Gulf of St. Lawrence during June and July. An unknown but possibly large proportion of the Northern contingent overwinters in American waters. The Southern contingent spawns in American waters between March and April primarily in the southern Gulf of Maine'--Context, page [1].

"An index of effort calculated from the USA commercial catch rate was used to fine tune ages 6-7-8 fishing mortalities. A 1980 F = 0.066 was considered to best represent the ages 6 and older stock status. partial recruitment on age 2 was adjusted to obtain a 1978 year-class size at age 1 of 2 billion fish while P.R. on ages 1, 3, 4, and 5 were adjusted to obtain year-class size at age 1 of approximately the smallest size observed. Various Y/R calculations and projections were made. These indicated that a 1982 catch of 115,000 mt would not adversely affect the stock status."--Abstract.
