Abstract

<p>It was possible to replace total fish meal in fish diet with protein source and additives, however, inclusion of plant protein sources often causes several disadvantages. Insect meals have shown their possibility as a prospective ingredient. One of the most popular insect meals, yellow mealworm (Tenebrio molitor) has been utilized for various fish species but few study was tested for red sea bream. Three iso-nitrogenous (45%) and iso-lipidic (15%) experimental diets were prepared. Control diet was formulated with fish meal (FM) and plant protein sources were used for formulating a non-fish meal diet (PP). 15% of mealworm meal was included in PP diet as a protein source and replaced the plant protein sources (MW). Only PP employed 1% bonito peptide to enhance the palatability. Duplicate groups of juvenile red sea bream (18.3 g) were fed the experimental diets for 60 days to near satiation. There were no significant differences among all dietary groups in the growth result, fish body proximate composition and digestibility. According to the result, it was possible to utilize 15% of mealworm meal in the non-fish meal diet for red sea bream.</p>
