What is NOT included in the definition of "engaged in commercial fishing"?

The definition of "engaged in commercial fishing" typically encompasses various methods of fishing that are primarily conducted for profit rather than personal consumption. Within this context, fishing with nets, using trawls, and utilizing lines (which can include various types of equipment) are all recognized methods that fit under commercial fishing practices.

Fishing with trolling lines, however, often pertains to a method that is more associated with recreational fishing rather than commercial endeavors. Trolling lines usually involve the practice of dragging baited hooks through the water while a boat is in motion, and while it can be used for commercial purposes, it is frequently seen in the context of recreational fishing. This distinction makes it less representative of the commercial fishing methods that are explicitly defined by the industry.

Therefore, fishing with trolling lines stands out as the option that is less likely to be included in the formal definition of "engaged in commercial fishing," which primarily focuses on methods aimed at substantial catches for sale or trade.
