人工控制培育缢蛏幼苗研究

ARTIFICIAL REARING OF LARVAE AND JUVENILES OF SINONOV ACULA CONSTRICTA(LAMARCK)

  • 摘要: 本文探索采用缢蛏动体实验生态研究的成果,控制缢蛏幼体各发育阶段较佳生态条件,进行人工控制培育幼苗研究,取得了较好的效果。单位出苗量为5.46万粒/M2至21.06万粒/M2,每公顷产量达8000千克至20000千克.这比自然海区正常年景蛏苗产量提高10—20多倍,从而显示出工厂化人工育苗的可行性和发展前景。文中也提及在人工控制培育幼苗中亟待解决的若干问题。这些为缢蛏人工控制培育幼苗进一步深入研究提供有益的参考。

     

    Abstract: The artificial rearing of larvae and juveniles of S. constricta wasconducted on the basis of the results of study on the experimental ecological condi-tions of the larvae and juveniles. The larvae and juveniles were reared under theirsuitable ecological conditions such as temperature, salinity, aeration, sanitationof the culture medium and nutrition. The result of output was satisfactory. The yieldof each unit was between 5.46×104 pcs/m2and 21.06×102 pcs/m2, 10-20 times as much as the output under natural conditions. Therfore, it is worthwhile to putforward this artificial rearing method. Some potential problems with regard to theartificial rearing of larvae are also discussed, and the data obtained are expected toprovide for the overall and further study.
