4.5.2. Classification of Reproductive Strategies

It is possible to construct the ecological classification of reproductive strategies (Most of these strategies are manifested in behavioral pattern and specialized structures. Basically there are 3 categories.

1. Non-guarders of eggs and young ones
2. Guarders of eggs and young ones
3. Bearers

1. Open substrate spawners
2. Brood hiders
