Trenton in Mercer County, New Jersey — The American Northeast (Mid-Atlantic)
“The Whole Art, Secret and Mystery of Manufacturing Sturgeon”
The section of the Delaware between Philadelphia and Trenton is a freshwater tidal river with the head of tide occurring here at the falls. Sturgeon and certain kinds of herring, notably shad, still ascend this stretch of the river to breed each spring, spawning their young in vast numbers. The smaller-bodied shad breed even further upriver, as far upstream as Lambertville and Stockton. Historically, while some of the catch was consumed fresh, most was pickled or smoked to allow for distribution to customers further afield.
The Lamberton Fishery – “There is at this place ….. great plenty of fish …..” 
Commercial fishing was in progress on the Delaware River below the falls by at least the 1750s. In the 1760s and 1770s, when pickled sturgeon was in great demand in the colonies
Initially, the driving force behind commercial fishing in colonial Lamberton was Charles Read, a prominent New Jersey politician, gentleman farmer and colleague of Benjamin Franklin. Read was leasing property for a fishery in Lamberton in 1763, by which time a fishpond and boiling house were already in place. Two years later he was advertising for sale an extensively developed property on the riverfront including: “…. Two stone buildings under the bank, the one a boiling house ….. the other a cellar for curing sturgeon and herring, together with the kettles and every utensils sufficient and proper to carry on the business.”
By 1770 the lease for the Lamberton Fishery was held by William Richards, another Philadelphia merchant and apothecary, and a leading proponent of the town’s development as a port. The fishery joined other Richards-run operations at Lamberton that included stores, houses, mills, a pottery, wharves and a schooner. During this period, locally caught pickled sturgeon were marketed both by William Richards
The Lamberton Fishery continued into the early 19th century, but gradually declined as the fortunes of the port waned. The fishery buildings were abandoned or demolished, and foundations and wharves lay buried for decades until construction of the highway tunnel began in 1999. Archaeologists monitoring the highway construction recorded foundations believed to have been connected with the fishery. Among the archaeological finds were countless sturgeon scutes (bony plates that cover most of the back and sides of this fish) and scales of herring, shad and striped bass.
Catching the Fish
Fishermen working the Delaware River below Trenton in colonial times would usually have made use of seines and weirs to catch large quantities of fish. Seines were large nets that were hung vertically in the water, wrapped around a group of approaching fish, and then dragged ashore. Weirs were traps made of wooden stakes, matted brush and netting that were fixed into the riverbed and int which fish were lured with bait. Both methods were partly patterned after traditional Native American fishing techniques.
Charles Read, owner of the Lamberton Fishery in the 1760s, included in his journal a sketch of a fish weir and offered this opinion on the best bait: “Take
Processing the Fish
Once caught and brought ashore on the Lamberton waterfront, fish were either immediately prepared for market or put into live storage in the fishpond on Douglas Gut for later processing. Preparing fresh-caught fish for human consumption involved pickling them in vinegar, packing them in kegs and shipping them off to Philadelphia and other population centers for sale. More extended preservation for up to two years could be achieved by curing fish in barrels of salt brine and then smoking them.
Fish were also rendered into other products, chiefly oil, glue and isinglass, which involved a series of controlled boiling and cleansing operations. Isinglass, a semi-transparent gelatin derived from the air bladder of sturgeon and other fish, was used as a clarifying agent in making jellies, liquor and glue. Processing of fish in this manner was certainly taking place at Lamberton, as indicated by documentary references and Charles Read’s contact with Benjamin Franklin on the subject of glue making.
