Agreed. For instance Barracuda will hit on anything blue/white and moving fast.
Sharks, generally the slimier the better. (We typically chopped up barracuda.) Doesn't need to be live or a whole fish for shark. Heck, shark fishing is more like fishing in a pond. Just put on a chunk of bait and let it drift.
We would drop anchor in maybe 80 feet of water. Then let out 30 feet of line and tie on a balloon. Then just keep letting out line and let it drift. The balloon worked as a bobber and kept your bait at a uniform depth.
Meanwhile we would have a 50 gallon trash can full of fish guts/chopped fish with a deck hose running through it essentially washing out a big fish oil slick to drift with the current. We would also get a 5 gallon bucket of frozen chum, punch a bunch of holes in it, wire a couple of milk crates around the bucket, (to keep the sharks from attacking th bucket), and lower this over the bow. As it thawed it would release more fish oils. With the chum bucket in the front and the deck hose running in the back we created a 40 foot wide oil slick/chum line that drifted out with the current. (40 foot boat).
If the sharks didn't come up for the bait after an hour or so then we would shoot the balloon with a rifle and let the bait drop. Eventually, you will catch a shark. You just needed to make sure you had a 10 foot steel leader between your line and your hook to ensure the shark didn't bit through the line.
The hard part was bringing them aboard. It's not pretty. It involves a gaff, a couple of rounds from the rifle and an aluminum baseball bat. - Heavy on the baseball bat.:moony:
