引进杂交鲆苗种在宁德市三都海区,经过385d的网箱养殖,达到商品规格,平均全长36.3 cm,平均体重606g,成活率达71%,饵料系数为8.3。研究表明,杂交鲆在生长速度、抗逆性、适应性等方面有较明显的优越性,能适应闽东海域夏季高温和冬季持续的低温。以Keys氏公式W=aLb,拟合养殖13个月杂交鲆的平均全长L(cm)与平均体重W(g)的关系式为:y=0.0117x3.0153,(R2=0.9905),其中b≈3,即此生长阶段的网箱养殖杂交鲆生长均匀。其平均全长与平均体宽成线性正比关系,y=2.6011x+0.7979,(R2=0.9764)。
The introduction of hybrid flounder seedlings in Sanduhai, Ningde City, after 385d cage culture to achieve product specifications, the average length of 36.3 cm, the average weight of 606g, the survival rate of 71%, the feed coefficient of 8.3. Studies have shown that the hybrid flounder in the growth rate, resistance, adaptability and other obvious advantages, to adapt to summer and winter high temperature in Fujian East continued low temperature. The relationship between average length L (cm) and average body weight W (g) of hybrid flies raised for 13 months with the formula of Keys’ formula W = aLb was y = 0.0117x3.0153, (R2 = 0.9905) b ≈ 3, that is, the growth stage of the cage culture Hybrid Flounder uniform growth. The average total length and the average body width into a linear proportional relationship, y = 2.6011x +0.7979, (R2 = 0.9764).
