14 fish out of ~275 is not minor, yet it doesn't overly concern me either since they did not all die at once... I don't know what you consider "bunches" of minnows either. Nor do we know how fast or when or how those died
Are the fish biting baited hooks? Do you see any visual signs of stress, like piping?
Your water looks overly fertile, and if you have a dense algae bloom, a couple cloudy days could really lower the dissolved oxygen levels...have you ever noticed several fish gulping air?
A great emergency aeration method for a smaller pond like yours would be to back a jon or smaller boat into the water and crank up the engine with the prop slightly cavitating, blasting bubbles and circulating water heavily...
