Abstract The fisheries management of the Lake Annecy stocked Arctic char Salvelinus alpinus fingerlings from different origins to improve the its catches.Different origions of stocked fish includes included catching progeny of wild spawning Arctic char from Lake Annecy and rearing the juveniles in the hatchery at Lake Annecy,, juveniles produced in a hatchery on Lake Geneva from eggs from wild fish in Lake Geneva, or using juveniles of a brood stock reared in the INRA research hatchery on Lake
the impact of Homo sapiens. As cities and towns grew in the years following the Civil War, forests were felled for timber, rivers were made into logging runs, and towering hemlocks were axed for tanneries. Brook trout, scientifically known as Salvelinus fontinalis, or the “little salmon of the fountain,”

My eyes opened to greet the early morning rays of light breaking into my log cabin bedroom windows. I could hear something on the roof, squirrels chasing each other back and forth on the sun-warmed shingles. Today was Saturday, the first day of the spring we have time to go fly fishing. The aroma of fresh ground coffee, drifting in from the kitchen, lifted me from my bed. The crackling pops of sizzling bacon, my father was frying in his favorite black cast iron pan, was as clear to my ears as
Humans have been performing aquaculture since Egyptian times. Aquaculture, by definition, is the process of growing aquatic organisms for consumption by human populations. Traditionally, aquaculture has been carried out in flow through systems, or pens in open water. These methods greatly increase the biogeochemical loading, as the fish excrete ammonia (~90%) and urea (~10%) (Timmons and Ebeling, 2013). The biogeochemical nitrogen cycle is driven by microorganisms, that perform nitrification, anaerobic
