Effect of ascorbic acid supplementation on sperm quality of rainbow trout (Onchorynchus mykiss)

Abstract

The aim of the work was to determine the effects of two different doses of ascorbic acid (300 mg kg-1 and 800 mg kg-1). They were evaluated on sperm quality of rainbow trout. The results of study showed that 800 mg kg-1 ascorbic acid supplemented diet was affected sperm quality positively such as sperm concentration, spermatocrit, sperm motility and fertilizing capacity of sperm. However, feeding with the diet supplemented with 300 mg kg-1 ascorbic acid increased sperm motility, but did not significantly affect according to control group. © Central Fisheries Research Institute (CFRI) Trabzon, Turkey and Japan International Cooperation Agency (JICA).
