摘　　要：探索了离岸深水抗风浪网箱养殖海鲈的生长参数.养殖海域水温全年平均温度为（23.4±5.8）℃,全年平均盐度为（22.9±4.5）‰.在深水抗风浪网箱养殖中,海鲈的饲料系数（FCR）保持在1.78 ～1.97,整体存活率为（89.3±5.39）％.海鲈体长与体重关系可用W=0.014 9L3.026（R2 =0.956）表达,所获b值高于长江与珠江口处所报道数值,但低于韩国Baekya岛海域所报道数值.This study explored the deep-water offshore anti-wave cage aquaculture sea bass growth parameters. Then annual mean water tem- perature and salinity in the cultured site were （23.4 ± 5.8 ）℃ and （22.9 ±t. 5 ） %. In deep-water offshore anti-wave cage culture, feed coefficient （FCR） of seabass was maintained at between 1.78 -1.97, the overall survival rate was at （89.3± 5.39 ）%. The body length and weight relationship of seabass can be expressed as W = 0. 014 9L3.0265 （R2 = 0. 956）, obtained b value was higher than the value reported in Yangtze Hivet and ＇the Pearl River estuary, but was lower than the value reported in South Korean waters island Baekya.
