Growth of white shrimp (Litopenaeus vannamei) and environmental variation in greenhouse ponds located in Zhoushan City of Zhejiang Province
In order to optimize prawn breeding mode, growth of white shrimp (Litopenaeus vannamei), phytoplankton species and environmental variation in six greenhouse ponds located in Zhoushan City of Zhejiang Province were monitored at the interval of 15 d between August 16 and October 30, 2017.

| description | In order to optimize prawn breeding mode, growth of white shrimp (Litopenaeus vannamei), phytoplankton species and environmental variation in six greenhouse ponds located in Zhoushan City of Zhejiang Province were monitored at the interval of 15 d between August 16 and October 30, 2017. The results showed that the body length (L/cm) and body mass (m/g) of the white shrimp increased with the breeding time (t/d), and the regression equations were described as L=0.744 9×t <sup>0.594 6</sup> and m=0.004 2×t <sup>1.823 7</sup>, respectively. During the investigation period, water temperature and pH in the ponds decreased with the prolongation of time.
