摘    要:杨梅坑人工鱼礁区位于大亚湾西北部,2007年12月25日完成投礁9.51×10^4m^3,礁区面积2.75km^2。分别于2007年、2008年和2009年春季,采用拖网和刺网相结合的方法,进行了1次建礁前的本底调查和2次建礁后的跟踪调查。结果表明,礁区2次拖网跟踪调查的游泳生物平均渔获种数分别为建礁前调查的2.13倍和2.50倍,平均资源密度分别为建礁前调查的3.38倍和8.19倍,平均尾数资源密度分别为建礁前调查的11.57倍和23.39倍。礁区2次刺网跟踪调查礁区游泳生物平均渔获种数分别为建礁前的2.29倍和3.14倍,平均渔获率分别为建礁前的5.51倍和9.49倍,平均尾数渔获率分别为建礁前的11.33倍和10.06倍。渔业资源生物多样性指数呈上升趋势。

关 键 词:大亚湾  人工鱼礁  资源密度  优势种  多样性

Abstract:On December 25, 2007, 9.51×10^4m^3 of artificial reef were constructed in Yangmeikeng artificial reef area (2. 75 km2 ) which is located in the northwest of Daya Bay. By trial net and gill net, we carried out a background investigation in spring of 2007 and 2 tracking investigations in 2008 and 2009. According to the 2 tracking surveys by trail net, after construction of artificial reef area, all of the average species number (2. 13 times and 2. 50 times than that of before) , average stock density (3.38 times and 8. 19 times than that of before) and average tail stock density ( 11.57 times and 23.39 times than that of before) of nekton increased. According to the 2 tracking surveys by gill net, the average species number (2. 29 times and 3. 14 times than that of before) , average stock den- sity (5.51 times and 9.49 times than that of before) and average tail stock density ( 11.33 times and 10. 06 times than that of before) of neklon increased. The biodiversity index of fishery resources is ascending.
Keywords:Daya Bay  artificial reef  stock density  dominant species  diversity
