Model fit: χ² (df) = 758.71 (364); CFI = 0.966; TLI = 0.957; RMSEA (90% CI) = 0.037 (0.034–0.041); SRMR = 0.065. SEM model used to predict the consumers’ attitude toward farmed and wild fish, their intention to purchase farmed or wild fish, and the purchasing frequency of fish products, in the control (n = 389) and information treatment (n = 387) groups. The R² values are displayed in Fig. 1
