Fathead Minnow Eggs The male fathead minnow selects and guards a nest site against both other males and egg predators. after females spawn in the nest, the male cares for the eggs until hatching (lord, 1927; markus, 1934). After egg laying, males continue guarding the eggs until they hatch, usually within five to seven days. this attentive care increases the survival rate of fry, contributing to a robust forage base in the pond.
Fathead Minnow Eggs The reproductive behavior of the fathead minnow is unlike that of most of the minnows which broadcast their eggs and give them no parental care. fatheads deposit adhesive eggs on the undersides of rocks and logs, and males guard the eggs during their incubation period.

In our study population in minnesota, males choose between two distinct nest substrates that differ in exposure to abiotic conditions affecting egg development: the underside of pond lily (genus. After the eggs are laid, the male fertilizes them and then takes on parental care, guarding the eggs, fanning them for proper oxygenation, and cleaning them until they hatch. fathead minnow eggs undergo a short incubation period. hatching time depends on water temperature, ranging from 4 to 6 days.

Results of research on an indoor hatchery system for fathead minnows. many producers now hatch golden shiner and goldfish eggs in tanks because it reduces the labor required for spawning mat collection. We quantified the importance of nest and paternal characteristics for survival of eggs of fathead minnow, a multiple batch spawner in which breeding males guard and tend nests. Individual male fathead minnows spawn and guard eggs for a period of several weeks during a much longer total breeding season. Fathead minnows spawn from early may through august. the adhesive eggs are deposited on the under surface of floating objects, and the male guards them. the eggs hatch in 5 to 6 days. adults reach a maximum of about 3 inches long. iowa anglers owe a great deal to this unobtrusive minnow.
