What are small boat alternatives to carrying large amounts of live bait?:

• Chunking (or cubing)  - Chumming with pieces of cut bait to hold fish near the boat.

• Berley buckets - Commonly used in Australia and New Zealand, these are buckets with holes in the bottom that mount on the transom. A long-handled chopper or masher is used to grind / chop / mash dead fish, squid, shrimp, or other yummies into a trail of fine pieces that flow behind the boat. Enough to get the fish active, but not enough to fill them up .
  
  
• Frozen chum buckets - Take some oily fish, grind them up, add some extra fish oils, and freeze into a plastic bucket. To use, cut/drill some holes in the top, and hang the bucket over the side on a rope. As the block melts, it puts out a chum slick similar to a berley bucket, but with less work. However, the attractiveness of frozen chum versus the fresh ground (sounds more like coffee than dead fish) is up for debate. Common in Southern California.
  
  
• Packaged Dry Chum / Fish Oils - Similar to the frozen chum buckets, but freeze-dried, and less messy. More commonly used on the US East Coast.
  
  
• Catching bait as needed - One good thing about the ground fish chumming methods mentioned above is that they often attract medium-to-large baitfish into the slick. Drop a Sabiki rig or other bait-catcher over the side and load up the tank, or use as needed. If the bait school disappears while catching bait, you better get a bait in the water with a hook ASAP.
