Abstract: The vulnerability to angling refers to the stable difference in the probability of being caught among individuals within a fish species, which is easy to be affected by various environmental factors. Fish in nature are affected by human angling activities, but the characteristics of the effects of different angling intensities on the vulnerability to angling and growth of the Cyprinidae fishes are not clear. In order to investigate the effects of different angling intensities on the vulnerability to angling and growth performance of the Cyprinidae fishes in the Yangtze River, the juvenile crucian carp (Carassius auratus) was used as the experimental object in this study under the condition of the laboratory (26.9±0.1)℃, angling with different intensities for three treatment groups that have similar size and physical fitness, three treatment groups high frequency group (angling once a day), medium frequency group (angling once every two days) and low frequency group (angling once every four days); three parallel groups were set up in each angling treatment group, including 40 fishes in each parallel group. After 10 hours of angling in each repetition, the angling activities of the group were stopped. The angling time, angling serial number and electronic information of each fish successfully fished were recorded. The angling ratio, individual fish angling interval, average angling serial number and its coefficient variation as well as the specific growth rate of fish during the experimental period (9d) were all calculated. The results showed that the angling proportion of the three angling intensity groups decreased with the increase of angling times, and the individual angling interval showed an increasing trend with angling time increased, which results in a negative correlation between angling proportion and individual angling interval. Except for the low intensity treatment, the average angling serial number of both the high and medium angling intensity treatments showed a decreasing trend with the increase of the angling times, and the coefficient variation of the average angling serial number of the two intensity treatments increased with the increase of the angling times. The average angling serial number of the three treatment treatments was negatively correlated with its variation coefficient. The specific growth rates of the three angling intensity treatments were all negative during the experiment, but there was no significant difference among the three groups. Our results suggested that high intensity angling activities can reduce vulnerability to angling of the juvenile crucian carp, and it can lead to obvious negative angling effect of individual growth, which shows that high-intensity fishing activities may affect vulnerability to angling and evolutionary trajectory of other related phenotypes of the wild fish populations.
