Abstract

The growth, order of anlage, and features of transitive stages of skeletal elements (cranial bones and serial structures: teeth, gill rakers, fin rays, pterigyophores, vertebrae muscles, predorsalia, and scales) in were studied in pre-larvae, larvae, and fingerlings of the nose char (N1-form), endemic lakustrine-riverine form of the Dolly varden Salvelinus malma complex of the Lake Kronotskoe, reared in the laboratory at a constant temperature. A comparative analysis of the early ontogenesis of sympatric species of nose char and white char of the Lake Kronotskoe evidences on a high similarity in the growth rate and development of the two forms, differing by the body length of free embryos and the larvae coloration.

摘要

研究了在幼虫前，幼虫中的骨骼元素（颅骨和一系列结构：牙齿，g耙，鳍状射线，翼龙，椎骨肌肉，前背和鳞片）的生长、,序和过渡阶段的特征。Kronotskoe湖的Dolly varden Salvelinus malma复合体的地方性lakustrine-riverine形式的鼻char（N1形式）和鱼种在实验室中恒温饲养。对克罗诺茨科湖的鼻char和白char同伴物种的早期致癌性的比较分析表明，两种形式的生长速率和发育高度相似，不同之处在于游离胚胎的体长和幼虫的颜色不同。
