Identification of Grilse (one sea winter salmon), which
comprise most of the annual rod catch is difficult.
Salmon grilse are often indistinguishable from multi
sea winter (MSW) salmon except by scale reading. They
are smaller on average (2-3lb in May, 5-7lb in July)
but when they enter rivers in September often attain
8-10lb and in October 12-15lb. Salmon usually weigh
over 8lb. Most are two sea winter (2SW) fish; these
are returning in spring average 8-10lb, in summer 12-14lb,
in autumn 16 - 18lb. Salmon tend to double in weight
during each full growing period (May - Oct) spent at
sea.
