Why does egg of cod fish only stores little food?

The eggs of cod fish store relatively little food because they are designed for high fecundity, meaning cod produce a large number of eggs to increase the chances of survival for some offspring. The limited food supply within each egg supports early development, but the reliance on spawning in nutrient-rich environments allows the larvae to access additional nutrients post-hatching. This strategy maximizes reproductive success in open ocean habitats, where conditions can be unpredictable.
