Effect of Light on the Development of the Hard Roe of ACIPENSER BAERII BRANDT, 1869


  • Mordovian State Nature Reserve, Pushta, Republic of Mordovia, Russian Federation


The goal of conducted experiment was to study the larval development of Siberian sturgeon Acipenser baerii Brandt, 1869 when influenced by light. The rate of hard roe development is almost independent on light intensity and spectrum. However, the survival rate and size of larvae at certain light intensity and color increase. The author revealed beneficial effect of green-blue light on noted indicators.
