The objective of this experiment were studying the nutrients consumption, appropriate light intensity and the culture system of green caviars (Caulerpa Lentillifera J. Agardh.) Trial 1 Study the rate of potassium nitrate 0.004 g/L and potassium dihydrogen phosphate 0.0003 g/L (nitrogen: Phosphorus 8:1) against the growth of green caviars .The results of the study showed that the algae of grapes had a range of adjustment during the 1-2 date period and began to have increased growth rate in the 3rd day and maximum growth on the 6th day weight 26.87 ± 0.96 g after that, the weight is reduced, which corresponds to the amount of the nitrate analyzed. The concentration is reduced gradually from the initial concentration of 19.10 mg/L. Reduced to 3.07 mg/l In the 8 th day Thus, the volume of nitrate is insufficient to grow. Trial 2 Study the appropriate light intensity for the growth of the seaweed 500 700 and 1000. Lux for 2 weeks found that the right light intensity for the growth of the green caviars is at 700 lux The highest growth rate was 100.39 ± 4.64 g. and Trial 3 Study the growth of the green caviars by developing three-form farming patterns : drip-irrigation, the water flow passes all the time and water flowing through every 15 Compared to the drowning, this is a form that uses the current Spirulina culture by experiments for 3 weeks. found that The is parenting a water-flowing system all the time. (last average weight 79.76 ± 9.47 g)
