Study on morphology and truss networks of the gilthead sea bream, Sparus aurata Linnaeus
WANG Jian-xun~1 ZHAO Lei ~ 2 ABSTRCT Different parameters of gilthead sea bream were measured. The average of body weight; body length; total length; caudal fork length; body depth; body width; head length; snout length; postortital length; eye diameter; length of caudal peduncle; and depth of caudal peduncle were 241.11±49.56 g、18.72±1.30 cm、24.15±1.39 cm、22.02±1.23 cm、8.20±0.63 cm、3.18±0.31 cm、5.56±0.36 cm、1.98±0.28 cm、2.47±0.21 cm、1.52±0.09 cm、2.56±0.45 cm、and 1.96±0.17 cm; respectively. The average ratio of BL/ED、BL/HL、BL/CPL、BL/ED、HL/ED、HL/CPL、HL/CPD、CPL/CPD、HL/HBE、and BD/BW were 2.29±0.10、3.33±0.18、7.49±1.25、12.37±1.12、3.72±0.30、2.26±0.43、2.88±0.25、1.31±0.21、2.29±0.16 and 2.59±0.22; respectively. The fin formulas of Dorsal fin; Pectoral fin; Ventral fin and Anal fin were D.Ⅺ-12~14、 P_ 1 .5+9~10、P_ 2 .Ⅰ-1+4、A.Ⅲ-11; respectively. The lateral line-scale and scale above lateral line were 56~69 and 6~8. The number of abdominal and caudal vertebrae were 9~10 and13~14 respectively. The premaxillary teeth formula was 1~5+7~10、2~13、4~9、0~9 / 0~7、3~10、3~15、4~11+1~4. The dentary teeth formula was 1~2+6~15、4~10、0~8 / 0~7、4~9、6~12+1~2. Through measuring and analyzing the countable and measurable properties of gilthead sea bream with traditional method; the structure diagram of network was established; based on the Truss network method; furthermore; the morphology of gilthead sea bream was described; which could provide scientific basis for studying the gilthead sea bream breed.
