On December 25,2007,9. 51 × 104m3of 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 and2 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 density( 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 nekton increased. The biodiversity index of fishery resources is ascending.
