Journal Title: Вестник Астраханского государственного технического университета. Серия: Рыбное хозяйство - Year 2012, Vol 0, Issue 1
Abstract
Изучена изменчивость длины рыла стерляди окской популяции. Проведен сравнительный анализ изменчивости этого признака у дикой и доместицированной окской стерляди. Показано, что длина рыла у окской стерляди зависит от возраста. Опровергнуто предположением о суще-ствовании двух рас окской стерляди – длиннорылой и короткорылой.
