Wanting to know more about Mackerel fishing in Gloucester because of the striking new public art mural created by Josh Falk, these bits of info, and painting by the Luminism master Fitz Henry Lane, came right up in my search –

Mackerel Fishing Expanded on Georges Bank

“Prior to 1820, mackerel were primarily used for bait, when Gloucester’s catch rarely exceeded 100,000 pounds or 500 barrels. With the introduction of salt mackerel, this fishery quickly expanded up and down the East Coast. In 1822, the Gloucester fleet found large schools of mackerel on Georges Bank, to the east and south of Cape Cod. This summer fishery landed 1.3 million pounds in 1821 and 6.8 million pounds in 1828. By the 1860s, the annual Gloucester catch was more than 30 million pounds. But mackerel could also prove elusive, with dramatic shifts in fish landings from year to year. For example, the enormous schools that predictably migrated each spring from off the Carolinas would nearly disappear in the 1830s, only to suddenly reappear by the early 1840s. Gloucester fishermen pursued mackerel up and down the Eastern seaboard and as far north as the Gulf of St. Lawrence.”

“At the Fishing Grounds” 1851 by Fitz Henry Lane

“This is one of a very few paintings by Lane that depict vessels at work on the fishing grounds. It was initially presumed to illustrate hand-lining for cod, but in fact shows schooners jigging for mackerel. Close inspection will show the fish to have mackerel stripes and the schooners are fitted with chum (bait) boxes on their sides from which the bait is scattered in a way called “tolling.”

In spring, mackerel form large schools off the mid-Atlantic coast and migrate northward with small groups going off to their local spawning grounds as the main school heads northward. When Georges Bank is reached, the school pauses to take advantage of this rich feeding ground; it thereafter breaks up into regional schools which swim off to smaller grounds in Cape Cod Bay, the Gulf of Maine, Canadian coastal waters, and particularly the Gulf of St. Lawrence.

The significance of this scene is that it shows the last great gathering of mackerel schooners before the fleet breaks up to follow the smaller schools to their spawning grounds. The 1850s marked a peak period in this fishery when the catching of mackerel by hooks was to give way to capture using the purse seine and subsequent rises and falls in the fortunes of this fishery.”
