You cannot find the option as there isn't a toggle for the eggs - you become eligible for them as soon as you build the aquarium. There's only one setting for finding aquarium-related items while fishing, and that's the option to turn prawn balls off. As it sounds like you're still finding them, that's unlikely to be your issue.
Aquarium settings can be found under the construction category:
Settings -> Gameplay -> Skills & Experience -> Construction
I think you're just being a tad unlucky here. The eggs can take a while to find, particularly when you factor in prestiges. Keep fishing, as you will find some eventually.
Your only other option would be to ask the community for direct assistance. If a player uses their golden cracker on you, you'll receive a golden egg in return. It might be worth asking your friends or clanmates if they have any to spare.
