Seeing goldfish with lots of frogs and reduced amounts of shoreline vegetation means the fishery does not have enough numbers of largermouth bass who control goldfish and reduce frog numbers unless there is lots of marginal and submerged vegetation. From your pictures vegetation seems to be well under control. Reproducing goldfish without significant population control will eventually transform the pond into muddy murky water which is probably not something you envision for a backyard pond. Review the above suggestions, reply, and we can provide lots of additional expert, well experienced advice.
