Growth of some internal organs and tissues was studied in carp (Cyprinus carpio L.) in order to provide baseline information on the growth process during the first posthatching stages of fish, and to compare the trend observed in fish to that known in other animals. Growth of organs and tissues (liver, pancreas, trunk muscles, digestive tract, eyes, nervous system) was studied in rapidly growing carp (Cyprinus carpio L.) larvae by means of a quantitative histological method. Mean body weight of carp larvae rose from 1.8 mg at 2 days to 50.4 mg at 18 days. Between 4 and 18 days after hatching (yolk exhausted; exogenous food only), the average specific growth rates of organs were around 31% per day for the liver and pancreas, 28% per day for the trunk muscles, 26% per day for the digestive tract (without lumen) and 19% per day for the eyes and nervous system. Compared to the total volume of tissues, liver (k = 1.19), pancreas (k = 1.19), and trunk muscles (k = 1.09) showed positive allometry, digestive tract showed isometry (k = 1.00), and eyes (k = 0.76) and the nervous system (k = 0.73) showed negative allometry. This study demonstrated that the growth process of some organs (i.e. liver, pancreas and digestive tract) is different between larval and older stages of carp, and that the development of carp larvae exhibit the same order of allometry coefficients as do certain mammals (e.g. rabbit and lamb) in their early postnatal stages: nervous tissue, digestive tract, muscular tissue, liver.
为了提供鱼类孵化后第一阶段生长过程的基线信息，并将鱼类中观察到的生长趋势与其他动物的已知趋势进行比较，对鲤鱼（Cyprinus carpio L.）的一些内脏器官和组织的生长情况进行了研究。采用定量组织学方法，对快速生长的鲤鱼（Cyprinus carpio L.）幼体的器官和组织（肝脏、胰腺、躯干肌肉、消化道、眼睛、神经系统）的生长情况进行了研究。鲤鱼幼体的平均体重从2日龄时的1.8毫克增加到18日龄时的50.4毫克。在孵化后4至18天（卵黄耗尽；仅摄食外源食物），肝脏和胰腺器官的平均特定生长率约为每天31%，躯干肌肉为每天28%，消化道（无管腔）为每天26%，眼睛和神经系统为每天19%。与组织总体积相比，肝脏（k = 1.19）、胰腺（k = 1.19）和躯干肌肉（k = 1.09）呈现正异速生长，消化道呈现等速生长（k = 1.00），眼睛（k = 0.76）和神经系统（k = 0.73）呈现负异速生长。这项研究表明，鲤鱼幼体阶段和幼鱼后期阶段某些器官（即肝脏、胰腺和消化道）的生长过程有所不同，并且鲤鱼幼体的发育呈现出与某些哺乳动物（如兔子和羔羊）出生后早期相同的异速生长系数顺序：神经组织、消化道、肌肉组织、肝脏。
