i had a separate compartment in my fish trap that i put live brine and frozen mysis in,then used to use a turkey baster to blast some food into the fish trap,then immediately close the door of my trap with the attached line.then i would slowly open it enough that a fish couldnt get in for the food untill the target fish approached the opening then i would open it just enough for him to get in. of course other fish would get in and eat all the food and i would have to re-bait ,but i always caught the most difficult fish.
