水温对珠江中下游鳜属鱼类早期资源补充的影响
|
摘要
为了解水温对珠江中下游鳜属(Siniperca)鱼类早期资源补充的影响,20072012年对珠江下游肇庆高要江段的鳜属仔鱼进行了连续采样调查。结果显示:20072012年的925次抽样中,鳜属仔鱼自每年4月开始出现,11月结束,平均持续(156±45)d,以59月为盛期。鳜属仔鱼首次出现的水温范围为19.3～25.8℃,最适宜水温为25.3～28.9℃。采用Pearson相关系数对鳜属仔鱼与水温之间的相关关系进行了分析,结果发现月平均密度与当月平均水温之间存在极显著的正相关关系。采用积温推算方法推算出鳜性腺进入快速发育的关键水温为15℃,其繁殖的活动积温和有效积温分别为(3 797.78±759.58)℃·d和(1 085.78±380.02)℃·d。有效积温与鳜属仔鱼总量、月平均密度均具有显著的正相关关系,说明了水温及有效积温的波动是影响珠江中下游鳜属鱼类早期资源补充的重要因素。
Continuous sampling in the Zhaoqing section between 2007 and 2012 were investigated to explore the influence of water temperature on drifting larval fishes of genus Siniperca in the middle and lower reaches of the Pearl River. A total of 925 individuals were collected from 20072012. The results showed that the Siniperca larvae occurred between April and November. The main occurrence time located between May to September, and lasts for 156±45 days. Water temperature ranged from 19.3 ℃ to 25.8 ℃ when the Siniperca larvae occured on the first time, and the optimum water temperature for this occurrence was between 25.3 and 28.9 ℃. Pearson Correlation analysis showed that monthly average Siniperca larvae density significantly positive correlated with monthly average water temperature(P<0.01,n=72). Results inferred from the accumulated temperature calculation approach indicated the key water temperature for the rapid development of the Siniperca gonads was 15 ℃. In addition, the active accumulated temperature and effective accumulated temperature for Siniperca breed were(3797.78±759.58) ℃·d and(1085.78±380.02) ℃·d, respectively. A significant positive correlation among the effective accumulated temperature, the abundance and monthly average density of Siniperca larvae(P<0.01,n=48) were also detected, which indicated that the fluctuations of effective accumulated temperature and water temperature exerted an important influences on the recruitment of the Siniperca larvaes in the middle and lower reaches of the Pearl River.
