Фенотипическая изменчивость основных промысловых видов карповых рыб (Сyprinidae) бассейна Каспия

Фенотипическая изменчивость основных промысловых видов карповых рыб (Сyprinidae) бассейна Каспия

Abstract

На 104 выборках 7 видов карповых рыб бассейна Каспийского моря изучено влияние на среднюю величину коэффициента вариации по совокупности морфологических признаков других переменных выборочных характеристик (размерной разнокачественности выборки, средних размеров изученных особей, численности выборки и др.) с целью оценки возможности использования этого показателя для количественного сравнения относительной морфологической изменчивости разных видов и выяснения характера ограничений в случаях применения. Показано, что на данный показатель влияют размерная разнокачественность, средние размеры и численность особей в выборке, он подвержен также половой и размерно-возрастной изменчивости, обнаруживая выраженную видоспецифичность и наличие различий между выборками одного вида, обитающими в разных условиях.
