Question

The approximate weight of 1 million carps spawn is

• A. 0.015 Kg
• B. 0.15 Kg
• C. 15 Kg
• D. 1.5 Kg

Hint:

A useful benchmark in Indian carp seed trade:
1 lakh (0.1 million) carp spawn weighs about 140–150 grams.
Therefore, 10 lakhs (1 million) spawn weighs approximately 1.4 to 1.5 kilograms.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Carp spawn weight estimates are required to plan stocking operations, calculate transportation density, and evaluate survival rates in hatcheries.
Key Formula or Approach:
The average weight of a single major carp spawn (just hatched larva) is approximately \(1.4\text{ to }1.5\text{ mg}\).
The total weight of \(1\text{ million } (10^6)\) spawn is calculated as:
\[ \text{Total Weight} = \text{Number of spawn} \times \text{Average weight of a single spawn} \]

Step 2: Detailed Explanation:
Substituting the values:
\[ \text{Total Weight} = 10^6 \times 1.5\text{ mg} \]
\[ \text{Total Weight} = 1.5 \times 10^6\text{ mg} \]
Converting milligrams to kilograms (\(1\text{ kg} = 10^6\text{ mg}\)):
\[ \text{Total Weight} = 1.5\text{ kg} \]
Thus, 1 million spawn weigh approximately \(1.5\text{ kg}\).

Step 3: Final Answer:
The approximate weight of 1 million carp spawn is \(1.5\text{ Kg}\).
