The Proximate of Natural Foods Gracilaria lichenoides and Ulva fasciata for Abalone Haliotis squamata Culture

Abstract

The aim of this research was to analyse the proximate in natural foods Gracilaria lichenoides and Ulva fasciata for abalone Haliotis squamata. The proximate analysis included water, ash, protein, crude fibre, and lipid components. The proximate of Ulva fasciata were 82.0% of water, 25.7% of ash, 3.5% of protein, 4.8% of crude fibre, and 1.7% of lipid, while in Gracilaria lichenoides were 92.5% of water, 50.3% of ash, 2% of protein, 4.4% of crude fibre, and 1.2% of lipids. Natural food Ulva fasciata provides better result of growth of abalone due to the nutrients contained in it particularly the higher value of amino acids and fatty acids compared to natural food Gracilaria lichenoides.
