                                                Abstract
   This research was held on October 20th ? desember 20th 2006, in laboratory Indoor Fishery,
    Animal Husbandry and Fishery University of Muhammadiyah Malang. The purpose of this
reaserch is to know the growth and survival rate freshwater crayfish (Cherax quadricarinatus) in
    which expansion on extreme density unit difference spreading and to know is how much is
     giving and growth of survival rate best of freshwater crayfish (Cherax quadricarinatus) in
                                          extreme density unit.
     The method which by used is experiment method and the study program that be used are
   complete random program (RAL) by using 3 treatment and 3 repeated cover : treatment of A
(spreding dense about 8), treatment of B (spreding dense about 14) and treatment of C (spreding
dense about 20). The parameter of test which be used are main parameter and support parameter,
  the main parameter are growth and survival rate while the support parameter are temperature,
     dissolved oxygen (DO), and acid degree (pH). The data analysis which be carried out by
    variance test, if F test give significant influence, thus it will go on to smallest significance
                                            different (BNT).
  The result of research show that the difference spreading dense of freshwater crayfish (Cherax
quadricarinatus) on extreme density unit did not give significant in fluence to survival rate, but it
gives significant in fluence to Specific Growth Rate (SGR), where highest growth level reached
 at teeatment of A (8) equal to 1,74 % BW / day. Result of measurement of quality water during
 research that is temperature : 24.0 - 24.7 ? C, pH : 8.1 ?8.0 and dissolve oxygen (DO): 5,8 ? 6,4
                                                  mg / l.
  Based on result of research can be concluded that the difference spreading dense of freshwater
crayfish (Cherax quadricarinatus) on extreme density unit did not give influence to survival rate,
      but it give influence to specific growth rate (SGR), the best growth was derived form A
                           treatment with spreading dense 8 fish/aquarium.
