Captain A. B. Crosby was a seasoned fisherman based in Yarmouth Bar, Yarmouth, N.S.. He was known for his extensive knowledge and experience in mackerel fishing, which typically began in mid-April and ended early in July.  Crosby's fishing method involved the use of a net, which was set up in the middle of April and taken down in May. The first catch of Crosby's net varied from year to year, with the first pursing usually taking place in mid-May.
