| 摘 要： | 于１９９０年８月－１９９２年４月在汉阳县军江渔场采集鳜标本。运用形态学和行为学实验方法研究其侧线管的形态结构和捕食行为反应特性。结果表明，鳜眶上管、眶下管管腔和神经丘直径最大，部分管道未埋入骨组织中；躯干部侧线管管腔和神经丘直径最小，全部埋入鳞片中；前鳃盖下颌管、眼后管等头部侧线管管腔和神经丘神经介于前二者之间，全部埋入骨组织中。

| Abstract: | The structure and behavioural response of the lateral line canal system ofa nocturnal predator, Siniperca chuatsi collected from the Juniang Fish Farm (HanyangCounty, Hubei Province) in october, 1990 and in May, 1991 were studied by Jakubowski 's method for manifestation of lateral line canals and their neuromasts andobserving the behavioural response of aquaria fish to mechanical stimuli This study of the canal system structure revealed a cutaneous fringe rundng oneach side up to the snout tip and back to the tail of the fish. The supraorbital and infraorbital canals were well developed with mtalmum canal lumen Most of the neuromasts in the two canals were obviously big, and protected only by bonybridges' The lumen of other canals narrowed gradually back Wards and downwards,and were covered with bone over large spaces.Behavioural experiments on blinded fish showed two kinds of responses to stimuliof low frequency vibration (<10Hz) from different regions near the fish. The stimulielicited feeding responses when applied before and over the fish mouth at behaviouroccurrence frequency of 51% and 55%. The fish was less responsive to stimuli fromother regions near its head, at behaviour occurrence frequency below 30%. Alarmcould only be observed when the stimuli were around the fish trunk.The presence of the rather well developed supre-and infraorbital canals andthe less well developed other canals indicates that the former may serve as a goodsubstitute sensory organ for eyes to detCct movable prey, and the latter to avoid striking obstacles during feeding of the fish in darlmess. |
