Аннотация

Проанализированы соотношение длина-масса (LWR) и индекс упитанности 14 видов рыб из реки Сох. Результаты показали, что 3 вида имеют изометрический рост (b=3), 1 вид (Triplophysa strauchii) – отрицательный аллометрический (b<3) и 10 видов – положительный аллометрический рост (b>3). При оценке состояния видов по индексу упитанности Фултона (K) установлено, что значение K было ниже 1 у Hemiculter leucisculus, Triplophysa daryoae и Triplophysa strauchii, и, напротив, выше 1 у Carassius gibelio, Cottus spinulosus, Leuciscus squaliusculus и Rhodeus ocellatus. Средний относительный индекс упитанности (Kn) для всех видов составил 100,51±10,075.
