Table 3.
The Pearson correlation (R2 value) and significant Bonferroni P values (within parentheses) among the standard body length (cm), body weight (g), condition factor, testis weight (mg), gonadosomatic index (GSI), pre-freeze motility (before adding methanol) (%), post-thaw motility (%), fertilization (%) and hatch (%) from thawed sperm of 19 males of medaka Oryzias latipes. Sperm from individual males were cryopreserved with 10% methanol at a cooling rate of 10 °C/min.
