A Standard Reference Diet for Crustacean Nutrition Research. II. Selection of a Purification Procedure for Production of the Rock Crab Cancer irroratus Protein Ingredient

Academic Article

Abstract

  • Obtaining reliable results from comparative crustacean nutrition studies requires a dietary reference protein which is available world‐wide and is nutritionally optimal for growth and survival. Traditional protein sources include “vitamin free” casein, egg albumin, whole egg protein, soybean protein, and others. These have proven to be inadequate for juvenile lobster (Homrus americanus). Purified rock crab (Cancer irroratus) protein is proposed to be nutritionally superior to casein for inclusion in semi‐purified lobster diets. Eighteen week feeding trials with juvenile H. americanus were conducted to compare diets containing protein obtained from rock crabs (Cancer irroratus), and produced by several different purification processes with a control diet having casein as its primary protein source. Diets containing purified rock crab protein were found to be superior to the control diet. Among the differently derived purified rock crab protein products, the precooked, isopropanol‐purified was the most effective dietary ingredient. Copyright © 1989, Wiley Blackwell.
