采用常规测量方法,以30尾全长35~50 cm,体质量400~600 g的养殖裸盖鱼( Anoplopoma fimbria)为实验材料,对其外部形态、可数可量性状及消化道结构进行观察和测量,初步研究了裸盖鱼的种质特征。裸盖鱼呈梭型,背面为青灰色,腹面为白色,全身覆鳞；第一背鳍16~18,第二背鳍12~14,腹鳍6~7,胸鳍14~16,臀鳍15~16,侧线鳞144~170,上鳃耙5~6,下鳃耙14~16,脊椎骨57~61,幽门盲囊4~6；全长/体长1.15±0.02,体长/体高5.27±0.08,体长/头长3.06±0.08,头长/吻长3.21±0.05,尾柄长/尾柄高3.19±0.17,体长/尾柄长5.46±0.20,头长/眼间距3.26±0.28,头长/眼径为6.73±0.31,肠长/体长为1.18±0.17,肠重/体重0.048±0.004,内脏重/体重0.103±0.014。1~2龄裸盖鱼种质特征研究结果可为裸盖鱼的育种提供基础数据。

In this research, the external morphology, meristic and metric characters, and structure of digestive tract of 30 ind sablefish, Anoplopoma fimbria (1 to 2 years old) with body length ranging from 35 to 50 cm and body weight ranging from 400 to 600 g were measured and studied using the common messuring method in order to understand the germplasm. The results were as follows:The fish is spindle-shaped, and covered with mackerel scale, and its body shows with grey back and white abodmon. Observed numbers of sablefish are:first dorsal fins:16-18 , second dorsal fins :12-14 , ventral fins:6-7 , pectoral fins:14-16 , anal fins:15-16 , lateral line scales:144-170, upward gill rakers:5-6, downward gill rakers :14-16, vertebrae:57-61, pyloric caeca:4-6;measurable parameters ratio of sablefish are:Tl/Sl:1. 15 ± 0. 02, Sl/H:5. 27 ± 0. 08, Sl/Lc:3. 06 ± 0. 08, Lc/Lmx:3. 21 ± 0. 05, Lpc/Hpc:3. 19 ± 0. 17, Sl/Lpc:5. 46 ± 0. 20, Lc/Io:3. 26 ± 0. 28, Lc/Oh:6. 73 ± 0. 31, Li/Sl:1. 18 ± 0. 17, Wi /Wb:0. 048 ± 0. 004, Wio/Wb:0. 103 ± 0. 014. In this research, the germplasm of A. fimbria aged 1-2 years was studied, which could be provided basic information in A. fimbria breeding.
