EVALUATING THE GROWTH RATE AND SURVIVAL RATE OF BLOOD CLAM Anadara granosa (Linner, 1759) FROM LARVAE TO JUVENILE STAGE REARING IN EARTHEN POND

Abstract

The investigation of “Evaluating of the growth rate and survival rate of blood clam (Anadara granosa) from larvae to juvenile stage in earthen pond” was carried out. during December 2017 to May 2018. First phase from larvae (Chotropoda stage) were rearing to juvenile (1-3mm) and the second phase juvenile (5-6mm). The research was done with three rearing trials. The results showed that: In the first stage, the survival rate of juvenile have no significant difference between time rearing (from 21,8-24%). The average length also reached 1070, 1120 and 1130 µm/larvae in 3 times, respectively). In the second stage rearing blood clam juvenile, the length has no difference between them but survival rate was too different. The survival rates in the three rearings were 30%, 19.4%, and 15.8%, respectively.
