Hi Paula, Happy father's day, since you did both jobs.
I've been waiting with baited breath for more details on your Fish Spy. Do you have a mechanism for aiming the camera or is it passive? Do you have schematics for it? Is it battery powered or do you provide power through the cable? If you have power, can you run stabilizing gyroscopes to reduce dependance on currents?
Can you secure your FS to the orange baited trap to see what is happening? I infer from the pictures of the captive ice fish that they are carnivorous. Do the oranges attract their prey or are they omnivorous (the ice fish, not the oranges)?
If you want to learn every detail of their lives you might provide them with an internet and email account.
Warmest regards, Damon
