Abstract: The effect of temperature on heart beat of the Amazonian fresh water snail, Ampullaria gigas Spix was observed in a water bath under controlled temperature. It was found that the heart beat increased with temperature under 38℃, and then decreased above 40℃. The thermal death point is 47℃ and the zero point is 3℃.A temperature gradient incubator was constructed to study the response of incubation to temperature. The results may be summarized as follows: the developmental zero for the egg is 15.4℃.The optimum temperature for incubation is 25-30℃. The egg does not incubate over 34℃. The effective accumulated temperature for incubation is 161.3 degree-days.The above results are highly important for snail breeding.

Key words: Ampullaria gigas Spix (Amazonian fresh water snail), Temperature, Heart beat, Incubation
