Movement and Survival of Brown Trout and Rainbow Trout in an Ozark Tailwater River
We evaluated the movement of adult brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss in relation to a catch-andrelease area in the White River downstream from Beaver Dam, Arkansas. Nine fish of each species were implanted with radio transmitters and monitored from July 1996 to July 1997. The 1.5km river length of a catch-and-release area (closed to angler harvest) was greater than ...
متن کاملThe growth of brown trout (Salmo trutta Linn.); factors influencing the growth of trout fry.
It has long been known that brown trout (Salmo trutta Linn.) grow to different sizes in different waters, and there has been much speculation concerning the factors determining these differences. Dahl (1918-19) suggested that the food supply and the degree of crowding were important; also that small, slowly growing trout were derived from smaller ova than those growing more rapidly. Southern (1...
متن کاملThe Role of Environmental Factors in Determining Early Survival and Invasion Success of Exotic Brown Trout
—Due to significant threats to native species posed by nonnative fishes, it is important to understand how species life history strategies interact with environmental conditions to explain the outcome of nonnative fish invasions. Brown trout Salmo trutta are prolific invaders but often exhibit upstream distributional limits in streams of the intermountain western United States. We used redd cou...
متن کاملCarotenoids in the reproductive cycle of the brown trout.
In the first paper of this series (Steven, 1948) it was shown that the tissues of the trout (Salmo trutta Linn.) normally contain j8-carotene, lutein and astacene. Lutein and astacene occur as esters in the red and yellow chromatophores of the skin, and may also be present in the muscles as free hydroxy-carotenoids. Carotene is present in the liver, which also contains xanthophylls but no astac...
