OBSERVATIONS ON BEHAVIORS OF THE CHANGJIANG FINLESS PORPOISE IN A NET CIRCLE IN RIVER AND IN POOLS

摘要: 作者对长江自然环境圈养条件下和人工饲养池中江豚(Neophocaena phocaenoides)的部分行为作了初步的记录和分析。江豚对人工饲养的适应与环境变化的大小以及群体结构受损程度有关。环境变化大,群体结构受损大,适应慢。反之亦然.江豚常以一母一仔、一母一仔一幼或一雄一雌一起活动,是群体构成的核心单元.存在救助、争斗等社群行为及嬉戏行为。抚养关系严格。对窄小的过道有畏惧反应。

Abstract: The behavior of the Changjiang finless porpoises, Neophocaena phocaenoides, in a net cirele and pools were recorded and analyzed. Its adaptation time to rearing was related to greatuess of the changes of the environmnt and the population structure. The greater the environment and population structure changed, the slower the adaptation, and vice versa. Mother and offspring or one mature female and one mature male often moved together which was core unit of the school composition.The animals showed cooperation behavior, conflict behavior, and play behavior, etc.Mothers refused to care non-offspring. The animals were afraid of narrow channels.
