Options

A. Pomfret
B. Catla
C. Rohu
D. Common carp

Answer

To determine which fish does not belong to the category of fresh water fish, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Fish**:
- There are two main categories of fish: fresh water fish and marine (sea water) fish. Fresh water fish live in low salinity environments, while marine fish thrive in high salinity environments.

2. **Identify the Fish Types Given**:
- The question provides four types of fish. We need to analyze each one to see if it is a fresh water fish or a marine fish.

3. **Evaluate Each Fish**:
- **Pomfret**: This fish can live in both fresh water and marine environments. However, it is often found in brackish waters and is not exclusively a fresh water fish.
- **Katla**: This fish is primarily a fresh water fish found in rivers and lakes. However, it is mentioned that it can also be counted among marine fish, which is incorrect. Katla is actually a fresh water fish.
- **Rohu**: This is a fresh water fish commonly found in rivers and is cultivated for food.
- **Common Carp**: This fish is also a fresh water fish and is known for its high protein content.

4. **Determine the Answer**:
- Among the fish listed, **Katla** is incorrectly identified in the video as a marine fish. Therefore, it is the fish that does not belong to the fresh water category.

### Final Answer:
**Katla** does not belong to the category of fresh water fish.
