温度对三疣梭子蟹行为的影响

描述了三疣梭子蟹的摄食、领域、防御、攻击及清洁行为。三疣梭子蟹在水温12℃以上摄食行为加强,领域与攻防行为也很明显,攻防主要其螯肢。三疣梭子蟹的清洁行为比较复杂,在光强度变化较大时较为明显,一般要持续15~20min。随着温度的降低,三疣梭子蟹的摄食、攻防、领域行为都明显减弱。

Effect of the Temperature on the Behavior of the Portunus trituberculatus

T his study focued on the food intake ,territory ,defense ,attack and cleaning behavior of the swim ming crab.The food intake behavior of the swim ming crab enhances when the water tempera-ture rise to above 12 ℃ ,as well as their territory ,attack and defense behavior. Their attack and de-fense mainly depends on their limb of pincers. The cleaning behavior of the swim ming crab is com-paratively complicate ,which become more obvious when light change greatly ,and will last for 15 to 20 minutes.The food intake ,territory ,defense and attack behavior of the swim ming crab will weaken as the fall of the temperature.
