Thanks for your comment! I have heard about using beer to catch slugs with a lot of success. Luckily, we have not encountered slugs. I am not sure if there are natural predators, but I have been reading about some natural remedies you can put on trees or even companion planting.
What kind of fish are you using in your aquaponics system?

The reason I was asking is because I am very interested in aquaponics and I have been thinking about trying one on a small scale. Do you raise food to feed your fish (duckweed) or do you buy a certain type of fish food?

I buy a comercial pellet. Trout feed still relies on a bit of fish oil to make. There are other fish that can eat vegetarian.
