2、渔业产业结构进一步优化
通过近几年坚持不懈地抓结构调整，渔业内部结构发生了重大变化，产业结构得到不断优化。2006～2010年，海南省渔业第二、三产业产值年均递增19%和17%，远快于第一产业的增长速度；三次产业比例由2005年的82：15：3转变为2010年的73：23：4。

“十一五”期间，我省捕捞作业结构进一步调整，加强了外海捕捞生产。目前，我省拥有大中型渔船4719艘，外海捕捞产量从2005年的18万吨提高到2010年的万吨，占海洋捕捞产量的份额从17％提高到28％，::1。
2010年，我省水产养殖总产量达50万吨，占渔业总产量的3%，比2005年增长5%，年均增长%。继续发展罗非鱼、对虾、石斑鱼、军曹鱼、尖吻鲈、卵形鲳鲹、东风螺、锯缘青蟹等国内外市场需求较旺的优势品种；进一步推行罗非鱼精养、高位池养虾、深水网箱养鱼、工厂化养殖东风螺等设施化养殖模式，使养殖方式从半精养向设施集约化养殖转变。全省罗非鱼养殖面积由2005年的20万亩增至2010年4万亩，其中新增山塘水库精养面积1万亩，水库大水面网箱养殖已辐射到全省各市县。对部分虾池进行改造，改养石斑鱼或鱼虾蟹轮养或混养等，%，%。以高新技术为依托的深水抗风浪网箱养殖尽显优势，增强了我省养殖业抵御洪涝、台风等自然风险能力。
