For those of you who can catch a lot of skipjack, you can make your own oil without too much trouble. Take an old cooler, preferably with a drain hole, lay down a layer of salt, then a layer of skipjack fillets, a layer of salt, fillets, salt, etc, till the cooler is full, or you are out of fillets. Finish off with a layer of salt. I use salt from the feed supply store; costs less than $5.00 per 50# bag. Let it set. Oil will be drawn from the skipjack and pool on the bottom of the cooler. If you want, you can use the fillets for bait, or you can squeeze them with some cheesecloth to extract the last bit of oil possible from them. Not only is this oil very heavy and concentrated, it is sticky. Get it on your fingers, and you'll not get it off without soap.
