Abstract

The aim of this work was to determine the viability of spermatocrit use in Piabanha's sperm concentration estimation. Gametogenesis of piabanha Brycon insignis (n=29) was induced with crude pituitary extract of carp and semen was further collected. The spermatocrit was determined using cappilar tube micro-centrifuge. The sperm concentration was verified by counting in "Neubauer chamber", after dilution. The verified sperm concentration (mean±standard deviation) was 24,38±3,84x10(9) spermatozoa/mL, and the spermatocrit was 16,14±5,20%. The regression model: v = 14,01.10(9) + 0,6428.10(9).X was significant (P<0,01) and presented adjusted R² = 0,75. Thus, the estimation of sperm concentration using the spermatocrit is possible.
