What is Danio rerio used for?
Danio rerio (previously Brachydanio rerio), the zebrafish, is increasingly being used as a model for studying genetic effects in vertebrate development. Zebrafish are native to the slow freshwater streams and rice paddies of East India and Burma, including the Ganges River.
Are zebrafish poisonous?
The results showed that prothioconazole exposure to zebrafish embryos produced a series of toxic symptoms, including hatching inhibition, shortening of body length, pericardial cyst and yolk cyst. In addition, prothioconazole exposure caused significant lipid peroxidation and oxidative damage.
Is zebrafish edible?
Danio rerio commonly known as the Zebrafish is a tropical fish belonging to the minnow family (Cyprinidae), commonly kept in aquaria and used for scientific research. Zebra Danios are of no economic importance in commercial fisheries as a food fish, but very commonly known and popular in the aquarium trade.
Is zebrafish a teleost?
In the last decades, the tropical teleost zebrafish (Danio rerio) has proved to be an excellent vertebrate system to model mammalian molecular events occurring during embryonic development, organ formation and adult physiology, either under normal or pathological conditions.
How big are zebrafish embryos?
Zebrafish Developmental Staging Series
| Period | Stage | Developmental Landmarks |
|---|---|---|
| Larval | Days 14-20 | 6.2 mm total body length; 10 teeth |
| Days 21-29 | 7.8 mm total body length | |
| Juvenile | Days 30-44 | 10 mm total body length; adult fins/pigment |
| Days 45-89 | 14 mm total body length; 12 teeth |
Do zebra fish eat other fish?
What Do Zebra Danios Eat? Being the hardy little fish that they are, Zebra Danios are far from fussy eaters. They will eat just about anything you feed them.
Can zebra fish eat goldfish food?
Zebrafish (Danio rerio) Due to their different body size, they can be combined with both comet and fancy varieties of goldfish. Zebrafish are usually too small to eat standard goldfish pellets. Although you may be tempted to use flake, smaller tropical fish pellets are best.
How much do zebrafish cost?

Can zebrafish help your eyesight?
U-M researchers are using the regenerative properties of zebrafish to develop novel strategies for treating blinding eye diseases. The tiny zebrafish may hold the key to slowing or even reversing eye diseases that affect millions of people, especially our aging population.
What do zebrafish and humans have in common?
Humans and zebrafish share 70 percent of the same genes and 84 percent of human genes known to be associated with human disease have a counterpart in zebrafish. Major organs and tissues are also common. Zebrafish genome has also been fully sequenced to a very high quality.
