【摘要】：口蝦蛄(Oratosquilla oratoria)是海州灣的優(yōu)勢(shì)漁業(yè)生物之一,在海州灣生態(tài)系統(tǒng)中發(fā)揮著重要作用。本文根據(jù)2011年3、5、7、9和12月在海州灣及鄰近海域進(jìn)行的底拖網(wǎng)調(diào)查數(shù)據(jù),對(duì)口蝦蛄的群體結(jié)構(gòu)、資源密度特征、空間分布和環(huán)境因子對(duì)其分布的影響等方面進(jìn)行了研究。研究表明,口蝦蛄的全年平均體長為(102.20±0.65)mm,5月平均體長最大(105.56±0.95)mm,7月平均體長最小(96.48±2.37)mm;幼體比例5月份最低(8.90%),12月份最高(28.67%);口蝦蛄的性比5月和7月小于1,其余月份均大于1.80;漁獲量變化趨勢(shì)為5月12月9月7月3月,漁獲尾數(shù)為5月12月9月3月7月。Pearson相關(guān)分析表明,3、5月相對(duì)漁獲量與葉綠素a、底層水溫均呈顯著正相關(guān)(P0.05);其他月份口蝦蛄的相對(duì)漁獲量與各影響因子之間的相關(guān)性均不顯著(P0.05)。研究還發(fā)現(xiàn),口蝦蛄的空間分布與底質(zhì)類型密切相關(guān),口蝦蛄主要棲息在砂、砂-粉砂-黏土和黏土質(zhì)砂類型的底質(zhì)中。
[Abstract]:Oratosquilla (Oratosquilla oratoria) is one of the dominant fishery organisms in Haizhou Bay, which plays an important role in the ecosystem of Haizhou Bay. Based on the data of bottom trawl survey conducted in Haizhou Bay and adjacent sea area in 2011, the population structure, resource density, spatial distribution and the influence of environmental factors on the distribution of Oratosquilla were studied in this paper. Research shows that The annual average body length of Oratosquilla was (102.20 鹵0.65) mm, the maximum body length in May was (105.56 鹵0.95) mm, the minimum body length in July was (96.48 鹵2.37) mm, the proportion of larvae was lowest in May (8.90%) and the highest in December (28.67%), the sex of Oratosquilla was less than 1 in May and July, and the other months were more than 1.80. The trend is May, December, September, July, March, The results of Pearson correlation analysis showed that the relative catch in May was positively correlated with chlorophyll a and the bottom water temperature (P0.05), but the correlation between the relative catch of Oratosquilla in other months and the influencing factors was not significant (P0.05). It was also found that the spatial distribution of Oratosquilla oratosquata was closely related to the type of sediment, and the oratosquilla mainly perched in sand, sand silt clay and clay sand.
