A method of improving fish culture by control of the stickleback, sucker, carp or bullhead catfish populations in an aqueous habitat comprising sticklebacks, suckers, carp or bullhead catfish and at least one member selected from a group of desirable fishes comprising chinook salmon, coho salmon, sockeye salmon, kokanee, steelhead, Kamloops trout, cutthroat trout, brook trout and Arctic grayling, said method comprising: adding to the aqueous habitat a compound containing diethyl esters of phosphoric, phosphorous, thiophosphoric or thiophosphorous acid that further contains a chloride or a chlorinated ethyl or vinyl group, the compound being added at an effective concentration operatively lethal to the stickleback, sucker, carp or bullhead catfish populations, but not operatively lethal to said selected members of the group of desirable fishes.
