The first video places emphasis on how effective this ancient technique of fishing is and how fishing overall is impacting the environment. In the second video, it was mentioned that they managed to catch around 20 tons of fish with some fishermen pulling up to 15 fishes per minute.
I always though that the giant net fishing ships were dominant but given these insightful videos, I am not so certain about that anymore. In the first video, it was stated that the type of tuna they were fishing could reproduce fast and bounce back.
I wonder how global fishing with many different types of fish is impacting the marine ecology though.
