Hey there. At least where I’m at, there is no vessel limit on bluefish or Spanish mackerel. A vessel limit is the amount of certain species you can catch regardless of how many fishing licenses you have on the boat. An example is Mahi Mahi. They have a vessel limit of 54, and a per license of 10. So even if you had 10 people on a boat, you can only keep 54, but that’s not the case of blue fish and Spanish. Fish Rules is a great app that keeps you up to date on all things regulations which can change year to year. There are also aggregates that you need to understand such as 3 grouper aggregates, reef fish aggregates, etc. but the app makes it really easy to understand.
