摘    要:使用EY60回声探测仪于2010年5月10-15日、9月28-29日分别对5种不同体长规格的鳙进行了目标强度及昼夜行为的现场测定.结果显示:鳙的全长范围为30.05~80.00cm,体长范围为25.10~68.80 cm,体重范围为0.3~6.0kg,对应的有效目标强度范围为-51.84~-42.06dB,最大目标强度...

关 键 词:鳙(Aristichthys  nobilis)  目标强度  行为特征  现场测定

Abstract:In order to accurately evaluate the target strength(TS) and behavior characteristics of Aristichthys nobilis,day-night acoustic measurement on 5 different lengths of A.nobilis was carried out on May 10 to 15 and September 28 to 29,2010,using the Simrad EY60 split-beam echo-sounder.Results showed that the total length,the body length and weight range of A.nobilis were 30.05 cm to 80.00 cm,25.1cm to 68.80 cm and 0.3 kg to 6.0 kg respectively,and the corresponding range of average target strength was-51.84 to-...
Keywords:Aristichthys nobilis  target strength  behavior characteristics  in situ measurement
