EFFECTS OF STOCKING DENSITY ON GROWTH AND SURVIVAL PERFORMANCE OF BLOODWORM Marphysa sp. JUVENILE IN TREATED SEAWATER

Bloodworms have all the necessary nutrients to form the basis of an exceptional aquaculture feed and artificial culture is recommended. The study was conducted to determine the effects of different stocking density on growth and survival performance of bloodworm, Marphysa sp. in treated seawater at Multi-Species Hatchery, College of Fisheries, Mindanao State University Tawi-Tawi College of Technology and Oceanography, Sanga-Sanga, Bongao, Tawi-Tawi, Philippines for a duration of 45 days using Completely Randomized Design (CDR) in three treatments; 10 (T1), 20 (T2) and 30 (T3) bloodworm juveniles with three replicates in every treatment. Results showed no significant differences among treatments (p>0.05). T2 has obtained the highest growth with final setigers (FS) of 51.7±10.3 and setigers gain (SG) of 38.9±10.6 but T1 has obtained the highest survival rate of 16.7±6.7% (p>0.05). Thus, results revealed that the stocking density has no significant effect on growth and survival performance of Marphysa sp. within the duration of the study.
