Introduction

There is great diversity in the reproductive systems of fish. Some produce eggs and sperm for external fertilization, while others copulate with the discharge of either fertilized eggs or young fish. There are several categories which can be used to divide fish into reproductively similar groups as follows.

Dioecism, Pathenogenesis & Hermaphrodism

  • The majority of fish are Dioecious (a species that possesses both males and females in separate bodies).

Monogamy, Polygyny, Polyandry & Polygynandry

External & Internal Fertilization

Pelagic & Benthic Spawners

Bearers, Guarders and Non-Guarders

Male

Female
