| 摘 要： | 在2005年4月和2006年3—5月,分别对大连虎平岛周围海域的斑海豹栖息地及斑海豹资源进行了调查,斑海豹的数量调查采用领地计数法;调查发现2005年春季在此处的斑海豹日最多为54头,2006年春季日最多为67头。在风浪较小,晴好天气,斑海豹在该海域出现的几率多;通过斑海豹数量的脉冲式变化推测每一批斑海豹在本调查海域不做长时间的停留。

| Abstract: | The dynamics of spotted seal(Phoca largha) population was studied in the waters from Huping Island to Maoniu Island as a haul site for spotted seal in Bohai Sea in April of 2005 and from March of 2006 to May of 2006.The results showed that the spotted seal was found in this waters from mid-March,peak at the beginning or middle of April according to the weather condition(ice melting in Liaodong Bay) and disappeared in a short period.The daily maximum and minimum numbers of spotted seals was 54 and 67 individuals in 2005 and 2006. |
