Thank you for the question.
In the Gulf of St. Lawrence, we fish with trapnets, a buoy, a rope and a trap. These are singles, to use the term used in Newfoundland.
Given the density of traps in the same zones, using Japanese traps in line or a trawl would cause a lot of overlap between fishing gear. This would make fishing more difficult and less safe for our fishers.
Some people have already done this in our region, but it is a little difficult. I've talked to fishers in Newfoundland who are doing what you say. They fish with trawls of 70 traps in a row. It's a little bit of a different world because trap density in the same zone is lower in Newfoundland, I've been told.
However, when you use buoys on demand, ropeless fishing, you use 10‑trap trawls, because it reduces costs and there are fewer fishermen in the same fishing zones.
