Fig. 1.

Dynamic change in nitrite concentration (A), nitrate concentration (B) and the total ammonia concentration (C) in ponds 1–13 during Penaeus monodon larva culture.

Fig. 2.

Survival rates of Penaeus monodon in ponds 1–13. Bars represent the mean ± SD (n = 3). * and ** indicate statistically significant differences (P < 0.05).

Fig. 3.

Number of heterotrophic bacteria (A) and vibrios (B) in the different seedling stages of Penaeus monodon. Different colours represent the 13 different ponds. Each bar represents the mean ± SD (n = 3).
