If you put your stick into a pond and collect adhesive fish egg or eggs, then transport them to another pond say 30 to 45 seconds away, how will you get the adhesive eggs off the stick with out damaging the capsule (corion), blastodisk, or yolk?
Brian, as a test this summer why not try this fish egg&stick collection theory you have and come back and report your results. Collect some eggs on a stick and after transport, move them off the stick to a well aerated container or one where you do a daily water exchange and then await hatching? I would love to see and hear about this real life lab experiment.
From my limited knowledge of most fish eggs they are adhesive for a short period after ferilization. Then they water harden and stickiness becomes minimal. So Brian expect some difficulty in getting eggs to attach to your stick.
