Fig. 1.
Three microalgae species. (A) N. oculata; (B) I. galbana; (C) C. muelleri.
Fig. 2.
The starved larvae which ingested three microalgae species for 1 h at 105 cells/mL, and then digested these in the filtered fresh seawater. (A) starved larvae ingested N. oculata; (B) starved larvae ingested I. galbana; (C) starved larvae did not ingest C. muelleri; (D) microalgae in the stomach were digested; (E) larvae were had finished digestion; nan, N. oculata; iso. I, galbana; emp, empty stomach; sto, stomach; dig, digestive diverticula.
Fig. 3.
Changes of microalgae area in the stomachs of larvae of different dph. A, 2 dph; B, 8 dph; C, 14 dph; D, 20 dph.
