  1. Developments after fertilization are expressed as a percentage of the control oocytes in the same spawn at the same stage (kept in spawning fluid for 30 min) (mean ± SE); 150 to 200 oocytes were counted in each sample. SOF synthetic ovarian fluid, GFR goldfish ringer, STI soybean trypsin inhibitor in GFR, TCF trout coelomic fluid, nd: not determined (see text). Different letters within rows indicate significant differences (p < 0.05).
