If you plan to keep your bait in a pen for an extended period, you’ll need to feed them. Live or frozen brine shrimp is the best way to get your bait eating right away. The catch, the boat ride, then the transfer all stress the bait and getting them to eat is always a struggle. Sometimes, the bait will eat the brine shrimp the very next day, but there isn’t much protein in brine shrimp, so when feeding them brine, it’s a good idea to also introduce protein-rich foods such as aquaculture fish pellets or flakes. Along with frozen krill, these foods will give your bait the protein and vitamins they’ll need to flourish.
