Fathead Minnow Eggs

Fathead Minnow Eggs > fathead minnows spawn between may and september when water temperature is 16 30°c, and usually at night. females spawn multiple times, up to 16 26 times, per season and generally release about 400 eggs for each spawning event. In the fathead minnow, the female supplies the eggs and the male cares for them until they hatch. the male defends a nest as females pass by and spawn eggs to be cared for by the male.

Fathead Minnow Eggs Fathead minnow eggs undergo a short incubation period. hatching time depends on water temperature, ranging from 4 to 6 days. after hatching, the newly emerged fathead minnow fry are small and transparent. these tiny fry initially feed on microscopic organisms, such as infusoria and zooplankton. The fathead minnow is a fractional spawner and, under favorable conditions, females can produce clutches of 50–100 eggs every 3–5 days. Among a wide assortment of animal and plant items, andrews (1970) found both fathead minnow parts and eggs in his dietary analysis of warmwater and coldwater fathead minnow populations. 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.

It describes the appearance and life cycle of fathead minnows, and outlines procedures for obtaining, breeding, and caring for them in the laboratory. this includes maintaining breeding populations, collecting eggs, and incubating embryos for use in aquatic toxicity studies. After fertilization, fathead minnow eggs are approximately 1.4 mm to 1.6 mm in diameter. following several well defined embryonic stages, eggs hatch within 4 to 5 days at 25°c. Schematic diagram of fathead minnow life cycle bioassay, showing stages of exposure (eggs to larvae to juveniles to mature adult) and endpoints measured at each sampling time. Eggs of fatheads are sticky and the male directs the female to deposit them on the underside of some structure he has cleaned and prepared as a nest. these eggs will hatch in about 5 days and the resulting minnow fry leave the nesting area after 2 days of protection by the male.
