Midwater trawlers vary in size—from small ships to large factory vessels. Large industrial ships pull gigantic nets through the open ocean and can catch an entire school of fish—spanning the size of five football fields—at once. These trawls don't impact the seafloor when used in the midwater zone. Setting these trawls on schooling fish using streamer lines to scare away seabirds and avoiding areas with an abundance of marine mammals can help ensure low levels of bycatch in midwater trawl fisheries.

Despite their size, ocean sunfish are docile, and pose no threat to human divers. Injuries from sunfish are rare, although a slight danger exists from large sunfish leaping out of the water onto boats; in one instance, a sunfish landed on a 4-year-old boy when the fish leaped onto the boy's family's boat. Areas where they are commonly found are popular destinations for sport dives, and sunfish at some locations have reportedly become familiar with divers. The fish is more of a problem to boaters than to swimmers, as it can pose a hazard to watercraft due to its large size and weight. Collisions with sunfish are common in some parts of the world and can cause damage to the hull of a boat, or to the propellers of larger ships, as well as to the fish.
