PENGARUH PERBEDAAN TEMPAT IMPLANTASI TERHADAP MODEL INTI, PERTUMBUHAN DAN SINTASAN KERANG AIR TAWAR Margaritifera sp

There are any problem which stuck pearl testeless product as unknown shell type in used, the desease which attack while keep and authority production technic in a mature manner which comprise the way of operate in saving core.. See the potention for high value jewerly. Should have to do research about the implementation technic which placed in many places in shell body. This research is consist 3 treat, are 1)imlementation outside the pallial line. 2) implementation into paralalel line and 3) implementation at cavity legs. While do the implementation, the average of singular shell weight which connected 74,13 gram until 82,07 gram. Keeping compact is 5 tail per koja. The result show that the implementation in different place can produce the different pearl’s model also. In 1st treat, pearl’s model which produced is barouqe, 2nd treat is blister. Than the 3rd treat is around. From observation of shell growth show that the biggest average weight individual shell growth in 1st treat (194,60 gram) and the highest sintasan reach in 2nd treat (74%). Key word : Margaritifera sp, implantation, growth, survival rate PENDAHULUAN
