How many eggs does a fish lay at one time?

There's no single answer to how many eggs a fish lays at one time. It varies drastically depending on the species of fish! Here's why:

* Species: Different fish have different reproductive strategies. Some species lay thousands of eggs, while others lay only a few dozen. For example, a cod can lay millions of eggs, while a seahorse lays just a few hundred.

* Size: Larger fish tend to lay more eggs than smaller fish.

* Age and Health: Older and healthier fish often lay more eggs.

* Environmental Conditions: Factors like water temperature, food availability, and habitat can influence egg production.

Here are some examples:

* Cod: Millions of eggs

* Salmon: Thousands of eggs

* Tuna: Hundreds of thousands of eggs

* Guppy: Up to 200 eggs

* Seahorse: Up to 1,500 eggs

To find out how many eggs a specific species of fish lays, you'll need to research that species specifically.
