中文摘要 | 水溫是影響魚類成長的主要因子,我們討論鱒魚成長模式的各種特式與水溫的關 係,發覺生長率會隨著水溫而變化,大多數的研究結果指出,鱒魚在水溫低於7度成長變得 遲緩而水溫高於19度成長加速,此外,鱒魚的成長也會受到食物的多寡、食物的大小、覓食 行為、緯度的不同、和生理變化的影響。 |
英文摘要 | Temperature is a major factor affecting fish growth in variant environments. The (relationship between water temperature and growth fate of trout (Salmo trutta L.) was examined in different characters. Growth rate varied considerable with water themperature. Most of the studies indicated that growth in brown trout is slow at temperature less than 7℃and greater than 19℃. Observed growth rates were compared with the growth rates estimated by a growth model for brown tout based a maximum ration. In addition, many studies showed that food availability, food particle size, feeding behavior, difference in latitude, and physiological changes influenced the seasonal growth patterns in brown trout. |
