Description:
Age and growth of populations of three fish species from sixteen lakes and reservoirs situated in the Patagonian Andean and the Patagonian Plateau Region (Argentina) were studied. They included two native species, the Patagonian smallmouth perch. (Percichthys trucha) and the Patagonian silverside (Patagonina hatcheri) and the introduced rainbow trout (Oncorhynchus mykiss). For the three species backcalculated lenght at age was obtained from scale readings. Von Bertalanffy growth curves were usually adjusted to data. For the three species, faster growth was related with lake productivity. (Document contains 38 pages.)
