大西洋鳕的游泳速度和耐力，是在温度为-0.3至1.4摄氏度的游泳水槽中测量的。 体长0.36- 0.52m的鱼的最大持续游动速度在0.9 ~ 1.0体长/秒（BL s-1）之间。 耐力随着游泳速度的增加而降低。 所有测量的鱼都不能在3 BL s-1下游泳超过1分钟。 讨论了与西北大西洋沃茨水域调查拖网的选择性相关的结果，其中鳕鱼发现于温度范围为< 0 to >8摄氏度的沃茨水域。
Swimming speed and endurance of the Atlantic cod, Gadus morhua L., were measured in a swimming flume at temperatures between -0.3 and 1.4-degrees-C. The maximum sustained swimming speed for fish 0.36-0.52 m long was between 0.9 and 1.0 body lengths per second (BL s-1). Endurance reduces as swimming speed is increased. All fish measured were unable to swim for more than 1 min at 3 BL s-1. The results are discussed in relation to the selectivity of survey trawls in northwest Atlantic waters where the cod are found in waters of temperatures ranging from < 0 to > 8-degrees-C.
