replenish dissolved oxygen and flush wastes, and both approaches usually incorporate a settling/aeration basin to improve water quality prior to discharge. Water availability will largely determine exchange rates in raceway culture, which in turn, determines stocking density and production per unit volume...
south of Mount Whitney, the highest peak in the United States outside of Alaska. Stocking of wild and hatchery-reared fish has extended its range to many waters at high elevation in the Sierra Nevada from El Dorado and Alpine Counties southward. The golden trout was originally found...

Evaluation of large-scale stocking of early stages of brown trout, Salmo trutta, to angler catches in the French–Swiss part of the River Doubs Around 500 000 brown trout, Salmo trutta L., alevins are stocked annually in the 24-km section of the River Doubs under study. All the alevins...
Nonetheless, we did find several populations with very little introgression, and discovered that a number of populations in the upper Kern River basin still largely represent the native genotype, despite the lengthy history of stocking.Erickson, Peter Bjorn...

Without human interference, the tiger trout would not exist as the brown trout’s native range covers Eurasia, and the brook trout inhabits the freshwaters of North America. Therefore they would have never encountered one another in the wild. However, during the 1800s, widespread stocking of no...
Thus, in the USA, triploid trout are not widely used in commercial rainbow-trout farming. Farming systems for rainbow trout are similar throughout the world. Fish are raised in flowing water in earthen or concrete raceways, with stocking densities depending upon water flow and water quality, e...
As a fish biology major and Oregon Department of Fish and Wildlife employee for four years, I understand the complexities of stocking hatchery fish in bodies of water where wild populations exist. Triploidy solves much of this dilemma. You simply do not want a hatchery fish that attempts to sp...
in the Sierra Nevada and eight distinct types of Chinook salmon (Table1). The diversity of salmonids is also the result of California’s large size (411 000 km2), varied topography, and long coast line (spanning 10° of latitude) which is adjacent to the California current region of the...
