In order to explore the practicability of the film photovoltaic engineering culture mode, the experiment on culture of Litopenaeus vannamei was carried out in the film photovoltaic engineering culture system, which consisted of shrimp culture system and photovoltaic power generation system. The experiment on high density culture of L. vannamei was conducted in three ponds, with stocking density of 500 shrimps/m2 and culture experiment cycle of 100 d. The average body length of L. vannamei was (9.77 ± 0.11) cm, and the average body weight was (10.80 ± 0.82) g. The yield of No. 1 pond was 4.25 kg/m2, the survival rate was 78.71%, and the feed coefficient was 1.22. The yield of No. 2 pond was 4.42 kg/m2, the survival rate was 81.85%, and the feed coefficient was 1.18. The yield of No. 3 pond was 4.07 kg/m2, the survival rate was 75.37%, and the feed coefficient was 1.25. During the culture, the range of water temperature at 08:00 and 15:00was 22.5~31.0 ℃ and 22.5~32.0 ℃ respectively, with maximum daily air temperature difference of 11.0 ℃ and maximum daily water temperature difference of 2.5 ℃, the pH was stable between 7.00 and 8.34, and the concentration range of nitrite nitrogen (NO2--N ) and total ammonia nitrogen (TAN) was 0~8.47 mg/L and 0~7.83 mg/L respectively. The film photovoltaic engineering culture of L. vannamei has realized the double benefits of shrimp culture and photovoltaic power generation, which has great practical value and is worth popularizing.
