Answer

To solve the given problem, we need to analyze the reproductive strategy of Pacific salmon fish and determine which option correctly describes their survival strategy.

### Step-by-Step Solution:

1. **Understanding the Reproductive Strategy**:
Pacific salmon are known for their unique reproductive strategy where they breed only once in their lifetime. This is a significant aspect of their life cycle.

2. **Evaluating the Options**:
- **Option A**: Producing few individuals of large size.
- This is not a characteristic of Pacific salmon. They do not focus on producing a few large individuals but rather a large number of offspring.
- **Option B**: Breed only once in their lifetime.
- This is true for Pacific salmon. They are semelparous, meaning they reproduce once and then die.
- **Option C**: Produce many individuals of large size.
- This is misleading. While they do produce many offspring, the size of the individuals is not the primary focus; rather, they produce a large number of smaller eggs.

3. **Conclusion**:
Based on the analysis, the correct answer is **Only B** (Breed only once in their lifetime).

### Final Answer:
**3 Only B**
