Porgy are a small fishes that swim in large schools, also know as bream.
The small net boats surround the the school and bring the ends together alongside the larger boat which lifts the nets and dump the fish into the hole.
They then carry the catch to a shore facility where they cooked down and made into cat food, omega 3, fish meal, and oil.
These were working the waters around where we were doing the seismic work.
