I have this wild idea to to remove Lion-fish from the ocean, instead fishing them wit a spear, would like to shock them with electricity and them suck them in thru a tube that will be placed on top and center of ROV and at the end of the suction tube place a fishing bag (net) that will collect the lion-fish.
Have already begin my build but would like to know if I create some kind of cover on top of both T200 # 5 and #6 (which are the both center ones) and divert that flow of water into a 2.5 feet x 4’ diam. tube on top of the ROV, can that make a powerful suction to suck the lion-fish inside the tube or should I need something else.
I know for sure that compress air into a tube will make it work, I use to do it long time ago while diving and searching for wrecks. I think is called underwater dredging.
