How can you tell that salmon fish eggs are dead?

It's difficult to tell if salmon eggs are dead simply by looking at them. Here's why, and what you can look for:

Challenges:

* Similar appearance: Dead and healthy salmon eggs can look very similar. They are typically round, translucent, and range in color from pale yellow to orange.

* No outward signs: There isn't a clear visual indicator of death like a change in color or shape.

What to Look For:

* Development: Healthy eggs will develop over time. You can look for the formation of a tiny embryo within the egg, which may become visible as a dark spot.

* Appearance:

* Healthy: Healthy eggs will be firm, with a clear, slightly oily fluid inside.

* Dead: Dead eggs may feel softer, and the fluid inside might appear cloudy or discolored.

* Smell: Dead eggs might have a slightly foul odor. However, this is not always the case and can be difficult to detect.

* Environmental factors: The surrounding water quality and temperature can also indicate the viability of the eggs. Check for any signs of pollution or unusual temperature fluctuations.

Important Note:

If you're concerned about the health of salmon eggs, it's best to contact a fisheries expert or a wildlife biologist. They can provide accurate information and guidance based on your specific situation.
