Hint:

Tapioca = Starch = Binder. Ethoxyquin is a very common exam question for Antioxidants. Oil cakes (GNC, Mustard Cake) are always Protein sources.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Compounded fish feed consists of various ingredients serving specific nutritional or structural roles. Ingredients are categorized as protein sources, energy sources, additives, or binders.
Detailed Explanation:
1. Groundnut Cake (GNC): GNC is a high-protein oilseed cake (approx. 40-45% protein) used as a major protein source in Indian aquaculture. (A-II)
2. Tapioca Flour: Tapioca contains high levels of starch. When heated, starch gelatinizes and acts as a binder, holding the feed pellet together and improving its water stability. (B-I)
3. Ethoxyquin: This is a chemical additive used as an antioxidant. It prevents the oxidation (rancidity) of lipids in the feed during storage, which is vital for maintaining feed quality. (C-IV)
4. Rice Bran: Rice bran is an energy-rich ingredient primarily serving as a carbohydrate source (though it also contains lipids and some protein). (D-III)
By matching these, we get: A-II, B-I, C-IV, D-III.

Step 2: Final Answer:
Option (C) is the correct match.
