What is Casper zebrafish?
-the casper strain of zebrafish is widely used for imaging of adult fish. -casper is a compound mutant composed of both nacre (mitfa) and roy orbison (an unknown gene) -here the authors identify a mutation in the gene mpv17 as the underlying cause of the roy orbison phenotype.
What characteristics do zebrafish have?
The zebrafish is about 2.5 cm to 4 cm long. In its larval stages it is transparent and as it matures to an adult it develops stripes that run along the length of the body and look blue in colour. Males are slender and torpedo-shaped usually with a pink or yellow tinge.
How are Casper fish different from other Casper fish?
After a year, they developed the Casper Fish™, which lacks pigment in its skin and scales, and therefore is transparent. The Casper Fish’s transparency allowed researchers to extend their research into the adult stage of this model organism. Two genes were involved in the development of the Casper Fish™.
What are some features that make zebrafish attractive for research?
because low cost and easy maintenance, transparent embryo, easy manipulation, high fecundity, and rapid embryonic development favor the zebrafish as an attractive model for in vivo assays with simplicity and versatility of in vitro assays over mammalian models which lack all of these benefits.
How do zebrafish reproduce?
If a divider is not used, the fish will lay eggs shortly after light onset. As the males chase the females around the tank, they stimulate spawning of eggs while releasing sperm into the water for fertilization. Wait approximately 15 – 30 minutes after pulling a divider to give the fish time to mate.
Are zebrafish embryos transparent?
Zebrafish embryos are transparent, permitting an unprecedented level of direct observation during embryonic development.
Can zebrafish be aggressive?
Despite the fact that zebrafish is a gregarious species that forms shoals, when allowed to interact in pairs, both males and females express aggressive behavior and establish dominance hierarchies.
Do zebrafish eat other fish?
Zebrafish are omnivorous, primarily eating zooplankton, phytoplankton, insects and insect larvae, although they can eat a variety of other foods, such as worms and small crustaceans, if their preferred food sources are not readily available. In research, adult zebrafish are often fed with brine shrimp, or paramecia.
How many eggs do zebrafish lay?
After 3 – 4 months zebrafish are sexually mature and can generate new offspring. A single female can lay up to 200 eggs per week.
What is nacre zebrafish?
nacre encodes a zebrafish microphthalmia-related protein that regulates neural-crest-derived pigment cell fate. Development.
Why zebrafish are used in research?
One reason that zebrafish are an important biomedical model is because zebrafish embryos are transparent and they develop outside of the uterus. This unique developmental process allows scientists to study the details of development starting from fertilization and continuing throughout development.
What is a transgenic zebrafish?
Transgenic zebrafish have essentially had exogenous genes added to their genome and as such can be used for many different experimental applications such as stable overexpression, dominant-negative mutation expression, and general analysis of gene regulation.
Can zebrafish regenerate body parts?
Adult zebrafish are able to regenerate different organs, including all fins (32), the spinal cord (33), the retina (34), the heart (35), the telencephalon (36), and the kidney (37). Interestingly, the mechanisms that control regeneration seem to be organ-specific.
