1.
At what stage in a freshwater fish's life do the , barbles, whiskers , lateral lines etc. really kick in and start telegraphing strong enough signals to a fish's brain to move away from an object?
- Does this happen while they still have egg sacks attached?
- Does it happen while they are YOYO's?
- Does it happen immediately at birth?
2.
Does color make a differnce in YOYO net avoidance?
white, green, black, being the basic ones involved?
Any studies or comments here?
