This fish forms harems with 3–4 females in each one. The females spawn shortly after sunset, or during the day when there is a large amount of cloud cover. The spawning season lasts from February to early October. [17] The oval eggs of species in the genus Lactoria hatch into the juvenile larvae. These larvae are distinct because they form ...
However, the decline in the stocks of whitefish species such as cod and haddock has seen pouting acquire a growing value as a commercial fish, [4] and they are now available both as whole fish from fishmongers and supermarkets and are also used in fish products such as fish fingers and ready meals. Due to their naturally short lifespan and ...

[4] The warmouth is occasionally confused with the rock bass ( Ambloplites rupestris ) or green sunfish ( Lepomis cyanellus ), both of which share its relatively large mouth and heavy body.

[3] The Agonidae is classified within the superfamily Cottoidea in the suborder Cottoidei in the order Scorpaeniformes in the 5th edition of Fishes of the World [4] but other authorities states that if Scorpaeniformes is excluded from Perciformes then Perciformes is recovered as paraphyletic ...
