Here is one way of looking at it :-) Even though its intent is a sushi dinner, it won’t be able to catch more than maybe one or two at best. It’s mostly hoping for little chorus frogs and tadpoles. I tell people all the time that fish are pretty darn good at staying away from their predators. They’ve been doing this a long long time.
If they’re not feeling sick, and up at the surface gasping, they will be very hard to catch. If it does gets a small one, that’s $10. How much you would you be willing to pay for bird seed to have birds and wildlife come into your yard?
I think most people would be willing to pay $10 a year for bird feed so one way to look at it is that you’re just providing some free range, organically grown, happy fish for a meal once a year.
