JOHN M. Trant or Allen R. Pratt St. E-mail: trant umbi. Cytochrome P aromatase CYP19 is the terminal enzyme in the steroidogenic pathway that converts androgens e.Zebrafish Danio rerio Husbandry.
The zebrafish has emerged over the past several decades to become an excellent mainstream animal model Lawerence, Earlier it was used as an aquarium fish and sometimes studied in the laboratory Laale,but now it is an omnipresent complement or alternative to the laboratory mouse. The growth in the usage of zebrafish in basic biomedical research has been driven by an ever-increasing array of advances in technology and molecular tools Lawerence, Obsedvation application of the zebrafish ranges from developmental genetics to the modeling of human disease, drug discovery, toxicology, and other diverse fields.
Gene information (ID: 307)
Hence, due to large-scale use and economic investment in infrastructure, it is very apparent to have scientifically based standards for husbandry, management, and care of the fish. Zebrafish are normally kept under laboratory conditions designed to replicate perpetual summer.
Depending upon food availability and temperature they can breed all year round Spence et al. Darkness allows the or to rest and the return of light will trigger fish to breed Vargesson, A layer of marbles, closely spaced rods, or mesh can be used to cover part or the whole of the bottom of the tank to prevent the fish-eating their eggs once laid Matthews et al Females consistently spawn more frequently and produce larger clutches of eggs with some males than others. A generalized Observatio of the techniques and some of the equipment used in relation to the spawning process can be An Observation of Development of Danio Rerio in Lawrence It is possible for both males and females to reach sexual maturity within three months of hatching.
Although establishments may begin using fish for breeding from this age Kurtzman,initial batches of eggs from such young females may not be of optimal quality. The highest number of embryos are reported to be obtained from fish between 6 and 18 months of age Vargesson, The mating behavior of zebrafish seems to be influenced by the exposure of mating partners to one another during the 24 hours before spawning begins at sunrise with males stimulated to perform courtship behavior by the detection of female gonadal hormones in the water Delaney et al.

Also that we would do without your excellent idea
Excuse for that I interfere … here recently. But this theme is very close to me. I can help with the answer.
In my opinion you commit an error. I suggest it to discuss. Write to me in PM, we will communicate.
Now all became clear, many thanks for the help in this question.
