This fish is often difficult to hook. They are also great at biting through light gauge hooks and fishing line. Although most do not specifically for this fish, if you decide to, use small cut bait pieces and ultra light tackle because they are small fish. 

One thing to remember is that when you remove it from your hook, due to the sharp spines you should use a dehooking tool so you do not have to touch it. If you are cast-netting, sometimes the leatherjacket fish will get into the bait school that you cast-netting. When you slide your hand up the net to remove the bait, you could get a wound from the leatherjacket fish if it got caught in the net.

Best Bait, Lures, & Tackle for Leatherjacket

How to Cook Leatherjacket

Although it is not often used as a fish that you eat, it has a taste that is similar to the Spanish Mackerel, which is an oily, mild taste. One way to cook this fish is to use the grill to cook the leatherjacket fish dish. You will need a couple of fillets for each person. Make a couple of slashes in the sides of the fish and lightly spray both sides with oil. Sprinkle the spice of choice over both sides.

Wrap two or three filets together in aluminum foil and place the packets over hot coals in the grill. Cook them for five minutes and turn the packets over, cooking them for another five minutes. When you check the fish, it should separate or flake when you test it with a fork. If they are not done, check them every couple of minutes until the fish is done.

You can also pan fry them. Heat two tablespoons of unsalted butter in the skillet until it is foaming. Depending on how thick they are, it should take about four to five minutes to cook on each side. Make sure that you do not have the heat too high and burn the butter. When you serve it, you can place it on some rice and then spoon the butter sauce over it.
