Tubifex-based microcapsules supplemented with lysine on GH expression in Barbonymus gonionotus larvae

Purnama Sukardi, Hamdan Syakuri, Laila Novitasari


Lysine is an essential amino acid which is not synthesized in animals, therefore, it must be absorb as lysine in to the body. The aimed of the research was to examine how dietary lysine supplementation of a tubifex-based microencapsulated diet influenced growth performance of juvenile Barbonymus gonionotus and expressed in its gene. The results showed that optimum level of lysine supplementation for the maximum growth of Barbo larvae was estimated 1.5% lysine inside Tubifex-based microcapsule.
