Johnb5, all fish you catch that we be frozen and kept for future use as bait should be put into a very cold solution of salt water and ice as you catch them. This will keep the baits in good shape, nice and firm when you go to use them in the future. When I refer to saltwater, I don’t just mean sea water. Mix Kosher Salt in with the seawater. As a gauge, I use approx. 2 large boxes of Kosher Salt in a 162 Qt. Igloo cooler, ½ filled with water, and plenty of ice. Adjust accordingly to your cooler size. Don't be skimpy with the salt, you won't oversalt them.
