Pig pellets and 1/2 cup of tuna oil stored in a fruit juice bottle is always on the boat. Clean and does not go off nor turn to mush untill put into a berly bag and into the water. A few handfulls last for hours. 

PCL feeds in massey will hook you up with some feed

one leg wrote: have found  fish candy with dryed oats myself the way to go  use a fine mesh bag and float it just under a tennis ball . whole thing weighs under 1/2kg  and it's all ok for IGFA

About how long does the fish candy last in a session?
What sort of fish visit when that berley is in the water.
Haven't tried the stuff out yet, but on the strength of what I've read about it, sure looks good

I've used some dry berley, but usually attracts everything except the target species... kahawai, snaps etc.
Will try out the pig pellets tho, heard they do the business
