Best places to buy fresh fish in N.B.?

[BarnNB]

Where are the best places to buy fresh fish and seafood in New Brunswick?

Obviously the best place would be from off the boats, but what are the logistics/protocols for this? Presumably they come back at a certain time? How does one negotiate a price? What wharves are best? What species are available?

A lot of questions, I know. Thank you for any information you can provide!
