Abstract |
Relationships between rates of food consumption, growth and food assimilation of juvenile coho salmon were determined for different experimental temperature conditions during the short-term, 30-day experiments. The efficiency of food assimilation was determined by measuring the quantities of food consumed and the amounts of fecal wastes produced. Concurrent long-term studies were conducted over four- and eight-month periods under similar temperature conditions. Growth rates of salmon at equivalent ration levels were compared between the short and long-term experiments. The growth rates of control fish were generally greater than those of fish exposed to elevated temperatures for each of the five short-term experiments. Increased rations ameliorated the effects of elevated temperatures on growth rates. (Modified author abstract) |
