According to the DFG, battlefront of northern pike had not been recorded prior to 1989 when an anglerfish caught the species in Frenchmans Reservoir, California. Two years later 15,000 gallons of Nusyn-noxfish were utilise in the Frenchmans Reservoir and tributaries of Lake Davis to eliminate the pike population. done the use of electro-shock boats and gill nets, post-sampling methods failed to capture any northern pike in the chemically treated areas.
As a result, DFG reason out the chemical treatment as a success. However terzetto years later in 1994, northern pike appeared more frequently on anglers lines than targeted trout. By 1995, the DFG conclude that eradication of the predatory pike was necessary in enjoin of battle to prevent their further spread in the state and to defend the trout fishery at Lake Davis (DFG, Feb. 7, 1995, Notice of Preparation).
Unlike the previous treatment, the DFG recommended development powdered rotenone in addition to Nusyn-noxfish and Pronoxfish, to treat the lake. Rotenone is a normally used pesticide that is absorbed through the gills and blocks the ability to process atomic number 8 (NYT).
