Pengaruh Potassium Media terhadap Pertumbuhan Mutlak, Osmolaritas Hemolymp dan Energi Basal dari Pascalarva Vaname (Litopenaeus vannamei, Boone)
Abstract: Absolute Growth,
hemolymp osmolality, oxygen consumption, and basal energy of Litopenaeus
vannamei postlarvae were investigated. After post larval stage, PL-20, the postlarvae
were acclimatized from sea water (25 ppt) to low salinity water (2 ppt) over 96
h. Treatments consisted of different concentration of K+added to distilled
water. Four different levels of K+ (0, 30, 60, and 90 ppm) were utilized. Ten
shrimp were placed in triplicate 40-L glasses aquarium. Results from the 42-day
K+ growth trial indicated significant differences (P< 0.05) in absolute
growth, hemolymp osmolality, oxygen comsumption, and basal energy. The values
in treatment A was significantly higher than than those under the other four treatments.
The results suggest treatment C were the optimum K+ level for culture vaname postlarvae
in low salinity water.
