Title Statement The effects of Nitzschia closterium on the survival and development of Penaeus monodon from zoea-1 to postlarvae-1 Summary, Etc. Penaeus monodon were reared from Z1 to M1 and from M1 to P1 using Nitzchia closterium at various feeding levels. Concentrations employed were 15, 50, 100, 150, 200 and 250 x 103 cells/ml. Algal density of 100 x 103 cells/ml seemed optimal for zoeal stages, where highest survival of 65.22% was obtained. However, not all larvae passed into mysis as compared to zoeae fed at higher densities (150-250 x 103 cells/ml). Feeding concentrations at 150 x 103 cells/ml was optimal for mysis. Larvae fed at this feeding level had a high survival rate of 62.22% and a faster rate of development. All larvae reached P1 on the fourth day of culture. Using N. closterium, Chaetoceros calcitrans and Phaeodactylum tricornotum as food, N. closterium and C.calcitrans-fed zoeae had consistently higher survival of 55.0% and 54.75%, respectively than P. tricornotum-fed larvae. The rate of development was also faster in zoeae given the two diatoms. Mortality in larvae fed with P. tricornotum was due to the cell configuration. Survival was high and development fast in mysis given C. calcitrans and N. closterium. Larval response to P. tricornotum was relatively poor Subject Added Entry - Topical Term PENAEUS MONODON   SURVIVAL   FISH FEEDING   BACILLARIOPHYCEAE   NITZSCHIA CLOSTERIUM           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
