It would be great if we could use any form of bait in the strainers. For example, it would be great if we could use the Worm from the Aquaculture mod. Perhaps a "forge:fishing_bait" tag should be created?
I also second the idea for allowing what can go into the worm bin to be customised. I have Pam's HarvestCraft 2 installed, which adds a ton of fruit and vegetables, and none of them appear to be usable
