G'day greekboi
Hard to tell I guess not knowing the depth of the screen shot, doesn't look like snapper to me. I get everything from a mass of arches to individual arches
Were I fish in SA the fish tend to be in the drop offs when the tide is running and move to the top of the drops on slack tide
My main technique for catching snapper is to motor around till I've found them and then drift over them. If they are there and hungry they eat anything, including a bit of plastic that looks like a fish or a squid head you left in the boat from last trip. I mostly use chunks of herring or by catch
It can also be productive to anchor and fish offal berley up, maybe not in a yak though
