For a young redfish, survival may depend on what its mother ate before spawning. If mama didn’t get enough essential fatty acids, then her offspring might not be able to catch food or get away from predators — even if the young consume a lot of fatty acids after they hatch.

This concept is known as metabolic programming. It says that pre-natal nutrition can have an effect on metabolism after birth. In humans, for example, there appears to be a link between a pregnant mother’s diet and a variety of health problems in children, such as diabetes, heart disease, and obesity.
