Check the shad off florida in the states, a youtube search for bluefish. Malheid! The result of 15-20 years of strict management. A lot of the fisheries there were in the collapsed state ours are in, back then, and they did something about it and now are reaping the rewards with fishing that we don't even imagine should exist here. In the old days for example there was an oil industry to send fish oil to europe which was cooked from fish in huge iron cauldrons in Langebaan, the fish used was the massive shoals of 10-15 kg shad they used to net in the lagoon.
They implemented controls in florida and north in the states, from control of commercial netting of the bait fish to reduced catch limits and slot limits for recreationals and the fisheries have rebounded to better than what the ballies can remember it ever being..

Most of the mal videos in the search are recent-ish and it is because the fishing has now in the last few years there, gone all-time. The main thing to catching a fish is to throw your bait or lure in front of one, all the rest is either about predicting when he will be there and what he want to eat or landing him. With lots of fish it makes it easy for everyone, with few fish it makes is hard for all except the pro's. That is where fishing in SA is at the moment for most fish. In the above two video's it would not matter what you threw at them, they would eat a flashing hook if you threw it out there..
