Морфометрические особенности предличинок шипа (Acipenser nudiventris Lov, 1828) на стадии вылупленияAbstract
The current paper presents results of preliminary analysis of the morphometric parameters of ship sturgeon prelarvae at the hatching stage. Particular attention is paid to the height and length ratio of the yolk sacof ship prelarvae, as compared with that of Russian sturgeon (A. gueldenstaedtii). The data on the measurement of the angle of inclination of the head of prelarvae aged up to two hours (mass hatching) are provided in the paper. Since these data have been collected during one spawning season, further research is needed for their correct interpretation.В статье проведен предварительный анализ морфометрических показателей предличинок шипа на стадии вылупления. Особое внимание уделено соотношению высоты и длины желточного мешка предличинок шипа, по сравнению с русским осетром. В работе приведены данные по измерению угла наклона головы предличинок возрастом до двух часов (массовое вылупление). Поскольку данные собраны за один нерестовый сезон, для их корректной интерпретации необходимы дальнейшие исследования.
