Seaweed, Enteromorpha intestinalis, as a Diet for Nile Tilapia Oreochromis niloticus Fry

A 42-d feeding trial was carried out to assess the potential use of the seaweed Enteromorpha intestinalis ("gutweed") as a food source for monosex Nile tilapia (Oreochromis niloticus) fry and to determine a maximum threshold fishmeal substitution rate. Six fish diets randomly assigned to t...

Description
Summary:A 42-d feeding trial was carried out to assess the potential use of the seaweed Enteromorpha intestinalis ("gutweed") as a food source for monosex Nile tilapia (Oreochromis niloticus) fry and to determine a maximum threshold fishmeal substitution rate. Six fish diets randomly assigned to tilapia juvenile and in triplicate were compared: replacing 0%, 10%, 20%, 30%, 40%, and 50% of fishmeal protein with a gutweed protein blend. Highest growth and cost reduction in tilapia fry production was observed in fish fed a 20% replacement diet.
