Hello,
This is probably a dumb question. In reading DNR reports on trout lakes, they talk about "invertebrate forage." Does anyone know what they mean, specifically?
Thanks,

Insect larvae...mosquito, dragonfly/damselfly, caddisfly, crawfish(ok, not insect)...

My guess would be crawfish and insects, but perhaps someone will have a better answer.

Larval stages of insects, freshwater shrimp, larval stages of frogs even, basically Trout are eating things before they mature and can fight back :-) p.s. Alot of times when you catch a trout you can see what they recently had to eat because they spit it up.

The answers in the above posts are correct. The invertebrate forage is basically the little creepy crawlers in the water. Here is a link to some illustrations:

Aquatic creepy crawlers

"Said one of these men, long past seventy years of age: 'I could carry, paddle, walk and sing with any man I ever saw. I have been twenty-four years a canoe man, and forty-one years in service; no portage was ever too long for me. Fifty songs could I sing. I have saved the lives of ten voyageurs. Have had twelve wives and six running dogs. I spent all my money in pleasure. Were I young again, I should spend my life the same way over. There is no life so happy as a voyageur's life!'"

Inverts are basically anything without a backbone, or vertebral column. Bugs, crawfish, snails, clams, worms, etc. Larval stages and adults are all inverts. Though not all inverts would be forage for all fish. A musky may not eat a clam, but a bottom feeder might eat a small clam.
