The goldeye in Canada occurs in large muddy rivers and associated lakes, being most abundant on the plains. Spawning usually occurs from late May to early July. In Lake Claire, Alberta, males reproduce first at 6–9 years of age and females at 7–10 years; in southern Manitoba first maturity averages 2 or 3 years earlier than this. Goldeye eggs were discovered in Lake Claire. They are bathypelagic or semi-buoyant, a characteristic which is rare among freshwater fishes. The egg is spherical, measures 4 mm in diameter, has a wide perivitelline space, coarsely granular yolk, and a large oil droplet. Prehatching developmental stages, including the multicellular blastoderm, the 41- and the 51-somite embryos, are described; as are the diagnostic characteristics of early larvae (7.27–7.63 mm), late larvae (11.8–15.6 mm), postlarval young fish (16.0–29 mm), and a 33 mm fish.

The confirmed freshwater fishes of Iran comprise 202 species in 104 genera, 28 families, 17 orders and 3 classes found in 19 different basins. There are also 23 species whose presence in Iranian waters needs confirmation by specimens. The most diverse order is the Cypriniformes with 120 confirmed species (59.4%) followed by Perciformes with 28 species (13.9%), Cyprinodontiformes (10 species, 5.0%), Clupeiformes (9 species, 4.5%), Salmoniformes (7 species, 3.5%), Mugiliformes and Siluriformes each with 6 species (3.0%), Acipenseriformes (5 species, 2.5%), Gasterosteiformes (3 species, 1.5%), and 8 other orders each with one species (0.5%). New species are still being discovered, 7 described in 2009, while others are being resurrected from synonymy, newly recorded from Iran, or exotic species newly established. Some taxonomic problems remain and are commented on briefly. Thirty-nine endemic species (19.3%) in 6 families and 23 exotic species (11.4%) in 8 families are listed here. The mosquitofish, Gambusia holbrooki Girard, 1859 is the most widespread exotic species.
