December 07, Typical total lengths are between 7 and 10 cm. They can also be found in larger lakes, streams, and other habitats, as well. Fathead minnows are omnivores that are categorized as Benthic filter feeders , sifting through dirt and silt to find food.

The carnivorous portion of their diet is made up of mainly insects, crustaceans , other aquatic invertebrates , and zooplankton.

The herbivorous portion of their diet is primarily made up of algae and phytoplankton. Fathead minnows will also feed on bottom detritus. Fathead minnows are a largely preyed upon fish that is eaten by mainly piscivorous fish such as Largemouth Bass , Northern Pike , Yellow Perch , Walleye , and various other types of fish.

Ostariophysan fishes, which include fathead minnows, possess an alarm substance, or Schreckstoff , in distinctive epidermal club cells. The alarm substance is released upon mechanical damage to these club cells due to a predator attack, and can be detected by other ostariophysan fishes which then engage in antipredator behaviors such as hiding or dashing away.

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.

In choosing a nest site, the newly reproductive male fathead minnow tends to take over the nest site of a parental male and evicting its resident rather than occupying an empty one.

The newer and more numerous the eggs are in the nest site, the more likely the current male is to be challenged by the newcomer. Paternal care of the eggs by the male includes rubbing the dorsal pad of mucus -secreting cells, which aerates the eggs and may help prevent disease; removing of diseased eggs from the clutch; and defending the clutch from egg predators, which include animals such as crayfish.

Egg survival and parental care behaviors also increase as the clutch size increases. A male fathead minnow defends the nest site for about three to five weeks at a time, thus continual turnover of new males in the population occurs.

The cost of allopaternal care is relatively small because fathead minnow eggs hatch in about five days, while the males can maintain a nest for about three to five weeks; thus, only a small proportion of the eggs that the male takes care of will ever have been adopted.

The main spawning season of the fathead minnow is from June through July, and they are in good spawning condition from mid-May to early August.

In males, tubercles occur from mid-May to early August with peak development going from June to July, at the same time as other indicators of reproductive condition.

Mucous cell counts also rise in males during the breeding season, but it stays constant in females. The chemical alarm signal in the epidermal cells also drops to almost zero in males during the breeding season.

Fractional spawning can result in 16 to 26 spawning events per female and an annual fecundity of 6, to 10, eggs per female.

Spawning can be affected by artificial estrogen, which can get from oral contraceptive pills to lakes via wastewater. Artificial estrogen feminizes male fathead minnows such that they produce vitellogenin , a protein involved in oocyte maturation, and alters oogenesis in female fathead minnows.

Because the fathead minnow is fairly tolerant of harsh conditions, it can be found in bodies of water that may be uninhabitable to other fish, such as waste drainage sites.

It has also been studied to investigate the effects of these waste materials on the aquatic life. Natural and synthetic oestrogens , such as oestradiol and oestrone , are present in sewage treatment works effluents.

In male fathead minnows, exposure to these steroidal compounds leads to an increase in plasma vitellogenin levels exceeding that of even mature female fathead minnows.

Vitellogenin blood plasma levels are an indicator for determining if chemicals have an oestrogenic activity to fish.

This is also accompanied by an inhibition of testicular growth, even if the exposure is in low concentrations or for a short period of time.

These studies showed that the presence of natural oestrogens, likely originating from humans, represents a new ecotoxicological issue. Bisphenol A is a chemical used to make polycarbonate plastic, epoxy resin , and other chemicals.

It is also weakly estrogenic, and many of the same effects of oestradiol and oestrone can be seen with this compound.

In the male fathead minnows, reduced somatic growth is seen. With females, egg production and hatchability are reduced. The effects take place more quickly in females than in males, though.

The effect of low pH on the fathead minnow has also been studied. Though survival was minimally affected by extended exposure to low pH, the minnow behavior was abnormal.

They showed stress behaviors, such as surface swimming and hyperactivity. In both males and females, their heads became smaller than normal. Males lose some of the brightness of their color.

Females become heavy with eggs but may not spawn, and the number of eggs per female is reduced. The eggs themselves come out abnormal, fragile and lacking turgidity, and the lower the pH, the less likely the eggs are to eventually hatch.

In fathead minnows exposed to cattle feedlot effluent, the males are feminized and the females are defeminized. The male fathead minnows have reduced testicular testosterone synthesis, altered head morphometrics , and smaller testis size, while the females have a decreased estrogen : androgen ratio, which is defeminized sex hormone ratio.

The fathead has been very commonly used as a baitfish , and more recently has emerged in the aquarium trade as the rosy-red minnow.

This colour morph was discovered in several Arkansas breeding farms in Both sexes of this strain have a rosy-golden body and fins and may express dark splotches of wild-type fathead coloration, and are sold in pet shops primarily as feeder fish.

They can also be used in home aquariums as pets. The fathead's invasive status in Europe is cited as the main cause for the spread of enteric redmouth disease among trout and eels there.

This species is also important as an Indicator species biological model in aquatic toxicology studies, similar to the Canary in a coal mine. Because of its relative hardiness and large number of offspring produced, EPA guidelines outline its use for the evaluation of acute and chronic toxicity of samples or chemical species in vertebrate animals.

Generally only the rosy-red variety is sold in pet shops though very often several wild types come in with each shipment , and is summarily the most likely to be found in an aquarium.

This thing looks like a real minnow. Der Eintrag wurde Ihren Favoriten hinzugefügt. Slowenisch Wörterbücher.
