If you are raising European Nightcrawlers
Been at it for about six months now. My worms are thriving in a large drilled wal-mart tote. Two thing these worms absolutely love. Corn cobs and watermelon rinds. after placing these two things in the bed. almost 100 % of the worms are found directly below them, When I take the old rinds out. They are about the thickness of printer paper.
Best bedding mixture I have used so far is a mixture of coconut coir , sphagnum moss and a dash of buss bedding.
Keeping in beneath ground level room. Temps seem to stay right at 60 or so during the hottest of days During winter have not had to add any kind of heat and temps stay around 50 or above. Their main food is layer chicken feed which I re-grind with spice grinder.
they do make an excellent bait and are extremely hardy on the hook. am going to use ice fishing this year as supposedly they handle extremely cold water a lot better than our native worms here in Ohio. They move so much on the hook they remind me of leeches when fished.
Takes about 5 minutes a day feeding and re-spraying with a spritzer bottle using distilled water. Don't want no salt or any other water chems on them. About every 60 days I change out the bedding. Very little time investment for a great bait.
