Koi and goldfish should keep mosquito larvae in check as the larvae must stay
at the top of the water and are easy pickings. Why they are so bad in temporary
ponds due to heavy rainfall, no fish to eat them.
But a Mosquito Dunk would be extra protection.

Frogs. Short of netting the pond securely you aren't going to keep most frogs
out. Some smaller species will not want to risk a pond with large fish but
reproduction drives are strong. Other frogs have no trouble.

Fish will eat a lot of the eggs and some of the tadpoles, much of it depends on
how much food comes from the pond keeper.
Toad eggs and toad tadpoles have a better chance of survival as they taste a
bit nasty like their parents. But again each pond and population of fish is
different.

You can keep some of the traffic down by netting up the frog/toad spawn and
transporting it to a nearby natural body of water.
You can try and catch the canoodling couples by spotlighting them at night and
using a sport fishing net to catch them. Cart them off too.
