Conversion efficiency and nutrient digestibility of certain seaweed diets by laboratory reared Labeo rohita (Hamilton).
Impact of three different types of seaweed diets on growth, feed utilization and nutrient digestibility of L. rohita was studied for 120 days. The seaweed diet fed fishes, especially Ulva based diet showed comparatively higher growth and weight increment. Good food conversion ratio, food assimilation efficiency, protein efficiency ratio and better nutrient digestibility were recorded for seaweed diet fed fishes. The results suggests the suitability of utilizing seaweeds, Ulva fasciata, Spyridia insignis and Sargassum wightii as partial substitute for fishmeal in formulated diets of L. rohita.
