采用实验生态学方法对条纹锯仔、稚、幼鱼形态发育的异速生长模式进行研究。对条纹锯(0–80日龄)的可量性状进行测量并运用统计学方法进行分析。结果表明，0–80日龄条纹锯全长的生长符合Y=4.529-(9.227×10-5)X3+0.015X2-0.189X (R2=0.994),干重增长符合Y=0.002X3-0.151X2+3.257X-18.232(R2=0.993)，其变化曲线呈“J”型增长。多数功能器官具有异速生长的特性，与摄食、运动相关的功能器官的生长拐点相对较早，在拐点之前，相对于全长呈正异速生长，拐点之后相对于全长呈负异速生长或等速生长。口裂、吻长、眼径、胸鳍、尾鳍的生长拐点分别为20、44、32、36、19日龄，其他相关器官的生长拐点相对较晚，头长、头高、腹长、体高的生长拐点分别为56、37、44、60日龄，其中头长相对于全长在拐点之前呈负异速生长，拐点之后呈等速生长。条纹锯部分功能器官的优先发育保证了在个体发育过程中的早期摄食能力和对敌害的躲避能力的完善，有效地提高了其生存能力。条纹锯异速生长模型的建立，有助于针对性地为其提供适宜条件，从而获得其最适和最大生长效能，为人工繁育和养殖条纹锯提供理论基础。

We applied experimental ecological approaches to study the allometric growth patterns at early developmental stages of Centropristis striata. Nikon E100 microscope and vernier caliper were used to measure the total length, mouth width, rostrum length, eye diameter, head length, head height, trunk length, trunk height, pectoral fin length and the tail fin length. All data were analyzed with appropriate statistical methods. The results showed that the growth of the total length of black sea bass conformed to the equation Y=4.529-(9.227×10-5) X3+0.015X2-0.189X (R2=0.994), and the dry body weight fit in the equation Y = 0.002X3-0.151X2+3.257X-18.232(R2=0.993), which displayed a J-shaped curve. Most of functional organs showed allometric growth patterns. We found that organs responsible for feeding and locomotive functions had relatively early growth inflection points. The growth inflection points of the mouth width, rostrum length, eye diameter, pectoral fin length and tail fin length were 20, 44, 32, 36, and 19 days post hatching respectively. The growth inflection points of other organs appeared at later time:head length, head height, abdomen length and trunk height had inflection points on 56, 37, 44 and 60 days post hatching respectively. There were also other models of allometric growth patterns, for example, the head length showed a negative allometric growth before reaching the inflection point but a constant growth pattern afterward. Allometric growth patterns ensure the priority development of organs that are required in key functions such as feeding and escaping from predators, which improved the viability of black sea bass. Our study will greatly help establish appropriate breeding conditions for black sea bass.
