Method of thermal induction was tested for the first time in the practice of Far Eastern aquaculture to obtain polyploid Pacific oyster Crassostrea gigas . Experimental blocking of meiosis was performed 25 min after fertilisation by brief (3 min) exposure to the temperature of 32 o C. Efficiency of the method was evaluated with assessment of survival, growth and development of control and experimental larvae (groups 2N and 3N, respectively) in conditions of plant.
