Improvement of common carp artificial reproduction using enzyme for elimination of egg stickiness

Original language description

This study summarizes optimization of techniques for common carp artificial propagation including improvements of activation solution (AS), the process of insemination, and elimination of egg stickiness. The optimum gamete ratio for good fertilization and hatching rate ranged from 8490 to 23 672 spermatozoa per egg, when dechlorinated tap water was used. Optimal ratio between eggs (weight in g) and AS (in ml) was defined as 1: 1 to 1:2. Different concentrations of AS such as NaCl from 0 to 34 mM (0 68 mOsmol kg(-1).) did not change fertilization and hatching rates. An AS adopted for carp spermatozoa (45 mM NaCl, 5 mM KCl, 30 mM Tris-HCl, pH 8) was compared with other saline AS; only the 51 mM (102 mOsmol kg(-1)) NaCl solution decreased fertilization and hatching rate. The AS containing 20 mM Tris-HCl at pH 9 increased fertilization and hatching rates compared to dechlorinated tap water of pH 7 or to AS of pH 6 and 7. Adhesiveness from the eggs was successfully removed by incubation in
