... 高濃度的環境污染物而導致免疫力較差有關。此外，有關六十隻雌性海豚的產幼 間隔及牠們與幼豚聯繫的研究發現，有很多幼豚只有一次與母親聯繫的目擊紀 錄，這可能與偏低的幼豚存活率有關，擱淺海豚紀錄的數據亦支持這個推斷。偏 低的幼豚存活率可能是由海水污染、及由船隻及觀豚活動所發出的水底噪音造 成。要減輕此問題，最有效方法就是儘快保護重要的海豚育幼生境。此外，海豚 母子的最短聯繫時間平均值為 20.4 個月，而大部分聯繫應不會超過 24 個月。雌 性海豚產幼間隔最長時間的平均值為 62.6 個月。總括來說，香港的中華白海豚 一般較為長壽，但雌性海豚的產幼間隔較長，而牠們的幼豚存活率及產幼能力亦 較低。這些...

...香港水域的海豚個體，共有十五隻於 2018 年不見所蹤，但其中四隻卻在伶仃 7 洋出現。國內水域的持續監察及珠江口中華白海豚的合作研究有助進一步了解牠 們於整個區域的空間動態。於大嶼山西面及西南面調查區之間、及於大嶼山西北 面及西面調查區之間移動的個別海豚，其數量亦於近數年持續下降。 在過去三個監察報告中發現的本港水域內的海豚使用模式有所改變，亦再次 透過分析個別海豚活動範圍而顯示出來。59 隻屬北大嶼山社群的海豚當中，44 隻個體曾將部份及整個活動範圍由大嶼山北面水域轉移至西面及西南面水域，但 於 2017 及 2018 年，卻有 29 隻個體的活動範圍轉移出現逆轉，牠們並再次回到 大嶼山北面...
