It may be coincidental. That area probably holds fish each year and the commercial fishermen know it.

One thing is for sure- commercial fishermen, categorically have no souls! They will lay nets 50 feet in front of recreational fishermen that are trolling, drifting etc. knowing they are messing up someones day. Ive seen them spread nets through packs of boats. Many lay nets not properly marked and so on. It is a poorly govorned professon!

Some netters have "native rights" and they are the worst kind. They have literally ruined many fisheries.
