These fisheries present a very interesting monitoring target. Here on the East Coast we have North, Central and South American fisheries mixing in with large numbers of freebanders and land-based stations coming out of Latin America (although US-based fishing fleets are also often heard on weird frequencies and within the legal marine bands).
That doesn't include the presumably extensive use of high-HF (25-30 MHz) frequencies for fishery radio
Since you're on the West Coast you have the Americas and Asia as monitoring targets and I'm sure there's a huge amount of HF maritime traffic coming out of Asia. Let's see if these guys change frequency again and there might be a set schedule they go by.
Here on the west coast we hear tons of peskies in the Pacific and Bering Sea areas.
There some local peskies on 5 MHz or 6 MHz non-maritime freqs, who are Canadians and NorthWest coast Americans (obvious accents).
The sound of engines can often be heard running in the background when they talk, which is evidence that they are mostly smaller vessels or crabbers.
Then there are peskies who are obviously Mexican, Central American, and South American, each with their different flavors of Espanol.
The biggest HF active group of peskies are Koreans.
There are Japanese peskies also, but usually they are on ITU marine channels.
There are Chinese language (Mandarin and Cantonese, and other various forms).
Indonesian languages are heard a lot around 10 MHz late at night, HF radio is really popular there.
But most of the Indonesians that are heard are probably in the general vicinity of Indonesia.
We often copy the peskies' drift buoy beacons on CW around 2 MHz and in the 26 to 28 MHz range.
Drift buoy beacons in some seasons used to be like herds of rodents on 2 MHz.
But more recently, they've been using the GPS buoys which don't transmit so often, and just send their position occasionally.
The GPS buoys are probably why the CW buoys are diminishing, because they don't have to RDF the GPS buoys.
The Japanese and S.Korean 27 MHz fishery allocations in the 11m CB spectrum were once upon a time popular for the local fishing, fish farm, or seaweed farming using walkie talkies.
Probably, the wide availability of cheap VHF/UHF and marine HTs (and cellular) has pretty much replaced the 11 metre use in those areas.
Today, while checking to see if Mix Radio was still on the air, some more S.Korean peskies were logged (probably Sajo Oryang again).
