For hygiene, water quality, and controlling disease problems the parallel design is better, as any contamination flows through only a small part of the system. WebTrout (and other finfish) farming is one of the most sustainable and efficient methods of animal protein production due to a near 1:1 food conversion ratio.And with more plant-based feed options available, the fish in, fish out (FiFo) ratio, the amount of wild fish needed in feed to produce a pound of farmed fish, is equal to or less than 0.5:1.

Absence of hyoid teeth is the most easily distinguishing characteristic from cutthroat trout. Prevention is the most important measure; good hatchery sanitation by restricting access, installing disinfectant footbaths and disinfecting equipment reduces the exposure of vulnerable fish to disease-causing agents. That feisty spirit, combined with the familys passion for their craft, has made this trout farm a successful supplier to sportfishing clubs since 1950, when Bartoshs grandfather Raymond Mouse Williams and his brother, Charlie, built their first five ponds fed by the sand spring headwaters of the creek and artesian wells on 60 acres of wetlands fringed with poplar, red oak, hickory, and birch trees.
