Do you know three types of egg development found in fish reproduction?

Nonguarders: Most freshwater fish do not guard their eggs, but scatter their eggs. Trout hide their eggs in depressions or "nests" of stones. The number of eggs a female trout produces is determined by her size. An 8-inch fish may lay only 300 eggs, while the nest of a 12-inch nest may contain 1,000 eggs!

Guarders: Some species of fish such as darters and catfish guard their eggs. Males will chase off predators.

Bearers: These fish carry their young as they develop, either inside the female or outside, often in the mouth of the male. Sharks, rays, molly and gambusia give birth to live young.
