摘要在文献中，被供应的母亲所生小牛的死亡率被确定为海豚供应计划中的一个关注问题。自1992年以来，澳大利亚莫尔顿岛坦格鲁马的野生海豚供应一直在发生。每天晚上，多达八只海豚在一个受管制的供应计划中被提供鱼。在本文中，小牛存活在Tangalooma供应计划的报告和对比，从野生种群和类似的供应计划在猴子米娅，西澳大利亚州。在Tangalooma，小牛存活率为100%，包括孤儿和第一胎小牛，预计这两种小牛的存活率都相对较低。探讨了高小牛存活率的可能解释。这些包括场地属性，如隔离的位置和高水质，觅食生态学方面可能有利于小牛的供应母亲，和管理制度中使用的供应计划（例如，供应的持续时间和时间;供应鱼的质量）。
ABSTRACT Mortality of calves born to provisioned mothers is identified in the literature as an issue of concern in dolphin provisioning programs. Wild dolphin provisioning at Tangalooma, Moreton Island, Australia has been occurring since 1992. Each evening, up to eight dolphins are provided with fish in a regulated provisioning program. In this paper, calf survival at the Tangalooma provisioning program is reported and contrasted with that from wild populations and from a similar provisioning program at Monkey Mia, Western Australia. At Tangalooma, the calf survival rate is 100%, including both orphaned and first-born calves, both of which are expected to have relatively low survival rates. Possible explanations for the high calf survival rate are explored. These include site attributes such as isolated location and high water quality, aspects of foraging ecology likely to benefit calves of provisioned mothers, and the management regime used in the provisioning program (e.g., duration and timing of provisioning; quality of provisioned fish).
