記事区分：原著[Author abstract]The amount of Macrobrachium nipponense caught in Lake Biwa may be governed by the water temperature of their habitat. In a project done to collect basic data on variations in the population of this, the effect of environmental conditions such as water temperature on the catch in pot fishery were studied. The data analized were the amount of catch obtained with prawn pots in the 29-year period from 1962 to 1990. The results suggested that the amount of catch was controlled by the accumulated water temperature, which is therefore an important factors in the M. nipponense population.[著者抄録]テナガエビ琵琶湖個体群動態におよぼす水温の影響について漁獲量変動から検討した。本種の成長期における高積算水温は漁獲対象となる個体群の成長を促進し、その効果は漁獲量変動に現れた。積算水温は本種個体群量の変動に影響する重要な環境要因であることが示唆された。
