### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the definition of fishery and what it encompasses. We need to identify the correct option that describes the fishery industry accurately.

2. **Analyzing the Options**:
- **Option 1**: "Catching of fishes" - This option only mentions catching, which is incomplete as it does not include processing or selling.
- **Option 2**: "Catching and processing of fish and shellfish" - This option includes catching and processing but omits selling, which is essential for a commercial industry.
- **Option 3**: "Catching, processing and selling of fishes, shellfishes, crabs, prawns" - This option includes all three critical components of the fishery industry.

3. **Identifying Key Components of Fishery**:
- Fishery is an industry that involves:
- **Catching**: The act of harvesting fish and other aquatic animals.
- **Processing**: Preparing the caught fish and shellfish for consumption or sale.
- **Selling**: Distributing the processed products to consumers or markets.

4. **Evaluating the Correct Option**:
- Since fishery involves all three processes (catching, processing, and selling), the only option that accurately reflects this is **Option 3**.

5. **Conclusion**: The correct answer is Option 3: "Catching, processing and selling of fishes, shellfishes, crabs, prawns".
