Selection, transport and acclimation of prawn fry
MetadataShow full item record
The most important criterion among many used by operators for choosing poostlarvae to stock in ponvds, is the stage of development. THe stages considered suitable for stocking (about PL20) can be identified by examination of anatomical features including the rostal spine number, the length of carapace and sixth abdominal segment. Pigmentation in uropods, size uniformity and activity of post larvae are useful considerations. During Transport,decreasing water temperature to lwer metabolic rate helps ensure the adequacy of oxygen in bags. Upon stocking, acclimation to the temperature and salinity of pond water is very importan. If changes are sudden, regulatory mechanisms may fail, resulting in moralities.
