Exclusive Economic Zone
The exclusive economic zone (EEZ) is an area of the sea adjacent to and beyond the territorial sea, extending out to 200 nautical miles from the baselines.
Within the EEZ, a coastal state has sovereign and jurisdictional rights over exploration and management (e.g. scientific research and protection of the marine environment), and economic exploitation of living and non-living resources in the waters above the seabed, in the seabed and beneath the seabed.
Within the EEZ, states other than the coastal state enjoy certain freedoms, notably those related to navigation and flight.
Canada has exercised its 200-nautical mile fisheries jurisdiction since 1977. Canada’s EEZ was formally established in 1997 when the Oceans Act came into force.
High Seas
The high seas is the area beyond the EEZ.
No state has sovereignty or jurisdiction over the high seas. The UNCLOS specifically provides that no state may claim sovereignty over any area of the high seas.
UNQUOTE
The assumption here is, based on the language regarding "state jurisdiction", you could use barbed hooks and sticks of dynamite. However, as soon as you crossed back into the EEZ, jurisdictions and compliance would come back into play and you might have to answer some questions about the dynamite and the barbs on your hooks
The one caveat to all this is the following: if you're fishing out on the High Seas and you hear over your SSB about the large mushroom clouds seen over Vancouver, Seattle and San Francisco, the dynamite and barbed hooks would them immediately become acceptable fishing gear either within or outside the EEZ and you should feel free to pack as many albacore as you thought fit given your vessel's stability limits
