摘要:

测定并分析比较菊黄东方鲀性腺发育为Ⅲ期雌鱼和Ⅳ期雄鱼的肝脏、性腺、肌肉和皮中水分、总脂和脂肪酸组成及含量。结果表明:1)不同组织中水分含量差异显著(P<0.05),雌鱼肌肉中水分含量最高,肝脏中含量最低;雄鱼精巢中水分含量最高,肝脏中含量最低。2)雌鱼肝脏、性腺、肌肉、皮的总脂含量分别为
(48.87±7.75)%、(11.77±1.44)%、(0.50±0.00)%和(0.13±0.06)%。雄鱼肝脏、性腺、肌肉、皮的总脂含量分别为(63.13±3.07)%、(1.70±0.10)%、(0.43±0.12)%和(0.30±0.20)%。不同组织中总脂含量差异显著(P<0.05),雌、雄鱼均为肝脏中总脂含量最高,性腺次之,皮最低。3)肌肉中,雌、雄鱼饱和脂肪酸相对含量最丰富,以雌鱼肌肉中C16∶0最为丰富,且显著高于肝脏、性腺、皮。肝脏中,雌、雄鱼单不饱和脂肪酸相对含量最丰富,分别为(46.4±0.5)%、(45.7±0.9)%,且均分别高于性腺、肌肉和皮。性腺中,雌、雄鱼多不饱和脂肪酸相对含量最丰富,分别为(28.6±1.4)%、(33.8±1.9)%,卵巢多不饱和脂肪酸相对含量与皮中多不饱和脂肪酸相对含量无显著差异(P>0.05),与肝脏、肌肉多不饱和脂肪酸相对含量存在显著差异(P<0.05)。精巢多不饱和脂肪酸相对含量与肝脏、肌肉、皮中多不饱和脂肪酸相对含量存在显著差异(P<0.05)。雌、雄鱼肝脏中脂肪酸绝对含量显著高于其他各组织(P<0.05)。

Abstract:

In this paper, the moisture content, lipid contents, and fatty acid composition of liver, gonad, muscle, and derma
from adult Takifugu flavidus were investigated. The male was in stage Ⅲ of ovary development, and the female was in
stage Ⅳ of spermary development. The results indicated that there was a significant difference in moisture content among
different tissues (P < 0.05). For the female, the highest moisture content was observed in muscle and the lowest moisture
content in liver; for the male, the highest moisture content was observed in spermary and the lowest moisture content in
liver. Meanwhile, the total lipid contents in liver, gonad, muscle, and derma of the female were (48.87 ± 7.75)%, (11.77 ±
1.44)%, (0.50 ± 0.00)%, and (0.13 ± 0.06)%, respectively. The total lipid contents in liver, gonad, muscle, and derma
of the male were (63.13 ± 3.07)%, (1.70 ± 0.10)%, (0.43 ± 0.12)%, and (0.30 ± 0.20)%, respectively. There was a
significant difference in total lipid content among different tissues for the female and male (P < 0.05), and the highest lipid
content was detected in liver, followed by gonad, and the lowest lipid content in derma. In addition, the highest relative
contents of saturated fatty acids (SFA) were shown in muscle for the female and male. The relative content of C16:0 in muscle
was significant higher than in liver, ovary, and derma. Monounsaturated fatty acids (MUFA) as the most abundant fatty
acids in liver were (46.4 ± 0.5)% and (45.7 ± 0.9)% in the female and male, respectively, higher than in gonad, muscle
and derma. The most abundant fatty acids in gonad were polyunsaturated fatty acids (PUFA) at levels of (28.6 ± 1.4)%
and (33.8 ± 1.9)% in the female and male, respectively. The relative content of ΣPUFA in ovary was significantly higher
than in liver and muscle (P < 0.05), while no significant difference was found between ovary and derma (P > 0.05). The
relative content of ΣPUFA in spermary was significantly higher than in liver, muscle, and derma (P < 0.05). The absolute
content of fatty acids in liver was 8.75% and 10.57% in the female and male, respectively, significantly higher than in gonad, muscle, and derma (P < 0.05). This research shows that Takifugu flavidus is nutritional and delicious. The liver can
be used for the development of fish oil. The liver is rich in PUFA, which can provide the basic material for the development
of cardiovascular drugs.
