Soybean Meal-Aquaculture

The digestible energy and the apparent digestibility coefficients of nutrients in several common feed ingredients were determined using juvenile haddock. Young haddock weighing about 94 grams were fed practical fish meal-based diets for five weeks and then assigned to a reference diet or experimental diet containing 30 percent test ingredient. Chromic oxide was used as the inert digestion marker. The following results were reported:

DIGESTIBLE ENERGY APPARENT DIGESTIBILITY COEFFICIENTS
  Protein Organic Matter Lipid
Herring Meal 18.3MJ/kg 95.9% 95.9% 97.9%
Shrimp Meal 18.0 92.2 89.0 83.0
Crab Meal 17.8 92.3 72.6 57.4
Soybean Meal 12.4 82.0 68.9 62.0
Canola Meal 10.9 83.0 58.9 87.2
Corn Gluten Meal 8.8 73.5 54.9 55.8

The authors concluded that based upon its high crude protein content and nutrient apparent digestibility coefficients and digestible energy content, properly processed dehulled soybean meal was found to be a good plant protein supplement to partially replace herring meal in haddock feed formulations.
