摘要
本文初步研究了尼罗罗非鱼对红、黄、绿、蓝、青灰色定置网片反应特性,并探讨了该鱼对青灰色网片的适应特性。结果表明:绿色网片对罗非鱼的阻拦作用最大,青灰色网片次之,红、黄色网片再次,蓝色网片最小。罗非鱼对青灰色网片具明显的适应现象,它们完成整个适应过程所需的实验重复次数约为7次。
The present paper preliminarily studies the characteristics of the reaction of Tilapia niloticus to set net pieces of red-,yellow-,green-,blue-,biueish-grey colors,and goes further into the adaptivity of Tilapia to blueish-grey net pieces. The results show: The green net piece has the greatest block affect on Tilapia, blueish-grey second,red and yellow third,and blue the lowest. Tilapia is obviously adaptable to blueish-grey net piece. Seven repeated experiments are needed to complete the whole adaptive process.
