摘要: Administration of 10 and 30 micrograms methionine-enkephalin (MET-ENK)/g bw (n = 10/dose) affected the propensity towards fighting in H. bimaculatus; increased, while decreased aggressive behavior. MET-ENK also a number behavior patterns displayed by fish. Moreover, "wet-dog-shakes" observed suggest that acts on opiate-receptors. Treatment with substance P (SP)/g induced chafing movements fish slightly. It increased biting air stone, which is evidence bimaculatus still aggressive, directing its attacks to different objects. When 4, 8, 12 somatostatin (SRIF)/g were injected, stopped for several hours after onset treatment, depending dosage. Somatostatin reduces blood glucose concentration, causing sudden stop behavior, 0.04, 0.1, 0.6, 1.0 3.0 IU prolactin (PRL)/g 5/dose) eventually
