Question

Proteins requirement of shrimps is ................percent.

• A. 30-40
• B. 5-10
• C. 10-15
• D. 15-20

Hint:

Larval and post-larval stages of shrimp require even higher protein levels (up to 45%), but grow-out feeds are formulated within the standard 30–40% range.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Shrimps are highly active, carnivorous or omnivorous benthic invertebrates.
Like other marine crustaceans, they have a limited ability to utilize complex carbohydrates as an energy source, making them highly dependent on dietary protein.

Step 2: Detailed Explanation:
The dietary protein requirement for commercially cultured penaeid shrimps (such as Tiger shrimp Penaeus monodon and Whiteleg shrimp Litopenaeus vannamei) is relatively high.
Depending on the species, growth stage, and stocking intensity, the optimal dietary protein levels generally range between 30% and 40%.
Diets with protein levels below this range result in poor feed conversion ratios (FCR) and stunted growth.

Step 3: Final Answer:
The protein requirement of shrimps is 30-40 percent.
