THE EXPERIMENT ON RAISING SURVIVAL RATE OF Chlamys farreri (JONES ET PRESTON) IN TEMPORARY FEEDING STAGE
Abstract:
The writer uses the perpendicular method to raise the survival rate of Chlamys farreri (Jones et Preston). There are many factors aifecting the survival, they are: time for removing from rearing tank, opening of the sack mesh and so on. Separation of seeds into different sack is preferred after 15-20 days. If seed density is too large, more substrate material should be added to the sack. The sack is preferrably of one layer with sack mesh opening of 15-34. Wind and wave are also important factors affecting the survival rate.
