This present study was conducted to illustrate the effect of dietary cysteamine on feeding, growth, biochemistry composition, hepatosomatic histological structure and metabolism taurine synthesis in juvenile turbot ( Scophthalmus maximus L.) (2.0 ± 0.01 g) fed high plant protein diets. A fishmeal-based diet (72.5% FM) designed as control (DietFM). Four isonitrogenous isolipidic diets consist 14.0% FM, 23.0% soybean meal 30.0% wheat gluten meal, which were formulated substitute FM with 0.0%, 0.05%, 0.1% 0.15% hydrochloride (labeled DietPP, DietCS-0.05%, DietCS-0.1% DietCS-0.15% respectively). Fish stochastically allocated into fifteen 200L tanks twice daily (06:30 18:30) apparent satiation for 9 weeks.
