how much of the population would pollock potentially feed

The amount of the global population that pollock could potentially feed depends on several factors, including the total catch of pollock, the nutritional value of the fish, and the dietary preferences of different populations. 

Pollock is a key species in the fishing industry, particularly the Alaskan pollock, which is a prevalent fish used in various products, including fish fillets, fish sticks, and surimi (a processed seafood product). The estimated annual catch of Alaskan pollock is around 3 million metric tons, although this number can vary year by year.

To estimate how many people could be fed, one needs to consider:

1. **Average Serving Size**: A typical serving size of fish is about 3 ounces (85 grams).

2. **Calories and Nutrition**: Pollock is relatively low in fat and calories while being high in protein. A 3-ounce serving typically contains about 100-120 calories.

3. **Population**: The world population is over 8 billion people.

Using the data points:

- If 3 million metric tons of pollock are harvested annually, that’s 3 million metric tons = 3 billion kilograms.

- Dividing by the average serving size of 85 grams gives approximately 35.3 million servings.

- This would mean about 35.3 million people could potentially be fed, assuming one serving per person and a universal preference for pollock.

However, this is a simplified estimation and does not account for dietary restrictions, waste, or the fact that not all pollock would be used exclusively for feeding humans. Instead, many fish products go into various processed foods and feeds for animals. 

In conclusion, while pollock has the potential to feed millions, the actual number would vary widely based on consumption patterns, distribution, and other sociocultural factors.
