Adult male Betta splendens were gonadectomized and tested twice for aggressive behavior two weeks later. In a mutual viewing test environment, it was found that gonadectomized animals maintained their aggressive behavior on all six indices of aggression at a level equal to controls. Animals that showed some testis regeneration and sham operated fish were also equal to controls. The results are interpreted to mean that adult aggressive behavior in male B. splendens may not be under the control of gonadal hormones. Pituitary gonadotropins, interrenal gland, and critical period hypotheses are given as possible explanations of the maintained aggressiveness following castration.
成年雄性暹罗斗鱼接受性腺切除手术，两周后对其攻击行为进行了两次测试。在相互观察测试环境中，发现性腺切除的动物在所有六项攻击指标上保持的攻击行为水平与对照组相当。出现一些睾丸再生的动物和假手术鱼也与对照组相当。这些结果被解释为意味着成年雄性暹罗斗鱼的攻击行为可能不受性腺激素的控制。垂体促性腺激素、肾上腺和关键期假说被作为阉割后攻击行为持续存在的可能解释。
