Cerezo–Valverde et al., (2008) used gelatine and alginate as agglutinants of bogue (Boops boops) and shrimp, to prepare diets for O. vulgaris, which promoted negative or moderate growth. However, an artificial wet diet based on crab muscle tissue agglutinated with gelatine was fed to O. maya, delivering adequate growth and survival, compared to crab muscle tissue that is commonly used as a control diet (Rosas et al., 2007; Quintana & Rosas., 2007); diets agglutinated with alginate promoted moderate growth for juveniles of the same species (Aguila et al., 2007).
