Commercial Fishing Types
One of BC’s most historic industries is our local fisheries and fishing industry, with 19 commercial fisheries across the province and over 1,900 registered fishing vessels plying the coast in 2024. However, the methods used by commercial anglers to snag their catches varies wildly between different fishers, target species, and locations, with numerous different approaches to fishing being used to great effect in local waters.
One of the most effective methods of fishing is seining, or the use of seine nets, which are massive nets that enclose themselves around entire schools of fish at a time. There are two types of seining used in BC, drag seining which uses nets set from the shore usually by the mouth of a river and enclosed manually, and purse seining, which uses rings, bridles, and an eponymous “purse” line to automatically create an inescapable pouch for fish on ships made for seining called, fittingly, seiners. While purse seining is far more common today, there is some use of drag seining as an experimental selective fishing method in eulachon fisheries.
Trolling also has a long history in local fishing, with the vast majority of commercial fishing in Union Bay being done from trollers historically. Trolling involves the dragging of one or multiple lines behind a ship (called a troller), with early trolling being done on a small scale by hand from row boats and the invention of gas engines for ships allowing modern operations to use mechanical winches and gas engines to lead multiple lines simultaneously and for far longer. Fish caught via trolling are often more valuable than those caught using other methods, due to the lack of a net meaning net scarring is an impossibility and the ability for trollers to clean and ice catch’s immediately.
