摘要： The toxicity effects of Alexandriurn minuturn and Gymnodiniurn on the embryonic development of Sparus macrocephalus were tested through the toxicological experiments about hatching spawns and developing larvae ofSparus macrocephalus.Alexandriurn minuturn and Gymnodiniurn solution was diluted into three groups (about 3000cell/ml,1500cell/ml,500cell/ml).The results showed that the hatch of the spawns was sensitive to both kinds of the algae.And the toxicity results from Alexandriurn minuturn were inferior to that from Gymnodiniurn.The test of larvae 96-LC50 showed that,larvae was more susceptible to the Gymnodiniurn and produced certain resistance to the toxicity of the algae.Both the Alexandriurn minuturn and Gymnodiniurn restrained body length and weight increase as well as ATPase and GSH-PX enzyme activities of the larvae,while restrain from Gymnodiniurn was stronger.In conclusion,the effects on growth and development of Sparus macrocephalus spawns and larvae resulted from Gymnodiniurn was much higher than that from Alexandriurn minuturn.
