The study was about the ineffectiveness of exclusion trawling nets.
AC I will explain some more about what you are really talking about and how it has nothing to do with what I do but it would be a good different discussion.
The ineffectiveness of exclusion trawl nets have to do with the difficulty in excluding larger fish from a bottom fish dragger because the fish you are targeting are the same size of fish you want to excluded . So they have been experimenting with net design and other stuff without the success the shrimp fleet has experienced.
The only problem with our debate is that I have nothing to do with those fisheries so when I give you the information about what I do you keep going to some other research. Our debate started with you thinking I was raping the ocean with a bunch of by catch and it ended up not being true so you are floundering around the internet trying to save face and it just didn't work.
