几种幼鱼曲线游泳能力的比较研究

摘要:
于1989年3—5月,利用视觉运动反应方法测定了黑鲷、黄鳍鲷、鲻鱼、鲤鱼和白鲢5种幼鱼的曲线游泳能力。结果表明,幼鱼游泳速度随环形水道半径增加而加快,但加快的速率逐渐减缓。随游泳时间的延长,游泳速度线性下降,实测耐久时间,黑鲷为66.7min;黄鳍鲷为66.8min;鲻鱼为104.4min;鲤鱼为70.3min;白鲢为58.8min。游泳能力指数,黑鲷为290.6;黄鳍鲷为147.3;鲻鱼为485.2;鲤鱼为243.5;白鲢为154.2。5种幼鱼曲线游泳能力指数大小顺序为鲻鱼>黑鲷>鲤鱼>白鲢>黄鳍鲷。曲线游泳能力的不同与鱼的大小、体型及生态习性等因素有关。

Abstract:
A March to May, 1989 study on the swimming ability of five young fishes, black porgy (Spams macrocephalus), yellow porgy (Spams lotus), grey mullet (Mugil cephalus), carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix) in curved tracks (including swimming speed and continued swimming time) with the optomotor response method showed: curve swimming speed of the carp was the fastest black porgy the second, and yellow porgy the slowest. With the increase of the radius of the circular track, the swimming speed increased, but the rate of this increase slowed down gradually. The swimming speed decreased linearly with the prolongation of sustained swimming time. Endurance time measured were 66.7min for black porgy, 66.8min for yellow porgy, 104.4min for grey mullet, 70.3 min for carp, and 58.8min for silver carp. The swimming ability index for black porgy was 209.6, for yellow porgy 147.3, for grey mullet 485.2, for carp 243.5, and for silver carp 154.2. The order of the value of the curve swimming ability index was grey mullet >black porgy>carp>silver carp>yellow porgy. The differences of curve swimming ability were related to the size of fish, body type and ecological habit. This paper proves that the optomotor response method is the best for the study of the pattern of curve swimming of fish and the rule of change of swimming speed with swimming endurance time.
