Question:
Which algae is used to convert mango wastes containing 20% solids into fish feed?
Which algae is used to convert mango wastes containing 20% solids into fish feed?
Show Hint
Microalgae like Chlorella are favored for fish feed because they are rich in essential amino acids, carotenoid pigments (which color fish tissue), and omega-3 polyunsaturated fatty acids.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Food processing wastes, such as mango pulp and peel waste, are rich in organic nutrients (carbohydrates) that can be bio-converted into high-value biomass like single-cell protein (SCP) or animal feed.
Step 2: Detailed Explanation:
- {Chlorella is a genus of unicellular green microalgae. It is photosynthetic and highly efficient at utilizing organic carbon from agro-industrial wastes (mixotrophic growth) to produce protein-rich algal biomass suitable for fish feed formulation.
- Aspergillus and Penicillium are filamentous fungi, not algae.
- Methylomonas (spelled as Methylamonas in the paper's typo) is a methane-oxidizing bacterium, not an algae.
Thus, Chlorella is the only algae listed and is widely used for this bio-conversion process.
Step 3: Final Answer:
The correct algae is Chlorella, which corresponds to option (A).
