After ei er use in experiments or at 8 days postfertilization, larvae were eu anized in 0.2 tricaine (also known as MS-222) followed by addition of bleach (1:20 by volume). Adult zebrafish were briefly anes etized using 0.02 tricaine before being weighted, imaged, or undergoing tailfin clipping. Zebrafish (Danio rerio) are being used in increasing numbers wi in molecular biology, developmental biology, neurobiology, genetics, cancer research and drug discovery, due to e low costs of maintaining em, eir short generation interval, e transparency of e embryos and e ability to manipulate e genome. ere are frequent meetings about e care and use of zebrafish. Wild-type AB strain adult zebrafish, Danio rerio (3- to 6-mon s old) were anaes etised in 0.1 MS-222 (Sigma) and e caudal fins amputated using a scalpel. Regeneration was en allowed to proceed until defined time points at 33°C. e trunk vasculature exhibits a global balance of arteries and veins, and local patterns favouring alternating vessel identities. e zebrafish trunk vasculature consists of a balanced network of arteries and veins (Fig. 1A) (Bussmann et al., 20).To explore e nature of is global artery-vein balance, we analysed e sequence of arteries and veins on bo sides of a -somite segment in 6.

Satou et al., 2009). undergoing ENU treatment. We suggested MS-222, a common anes etic used for fish, be used during treatment. ere was some discussion about whe er or not e use of MS-222 would interfere wi e mutagenic properties of ENU. So what did we do? Well, we conducted a pilot study and found at using a low dose of MS-222, about mg/L. Polyamines are small poly-cations essential for all cellular life. e main polyamines present in metazoans are putrescine, spermidine and spermine. eir exact functions are still largely unclear. however, ey are involved in a wide variety of processes affecting cell grow, proliferation, apoptosis and aging.

In addition 11, 20  · Abstract e zebrafish community has been steadily growing in e last 20 years in Europe. Given e federal structure of Europe, is increase in zebrafish research generated a need for a strategic forum to identify and discuss exciting new areas of research and funding opportunities as well as to address infrastructural and legal issues of experimentation, transport, and husbandry of zebrafish. Stunning fish significantly increased plasma cortisol and glucose levels (bo Pfish using ei er clove oil or MS‐222 had no effect on ese hormone levels. In contrast, e levels of GH, T 3 and T 4 hormones were unaffected regardless of whe er fish were eu anized by stunning, MS‐222 or clove oil. Variation. e presence of e FTR @60 in e presence of MS-222 suggests at even at e high doses of MS-222 used in is experiment, larvae are able to sense e stimulus. Because MS-222 anes esia interfered in regulation of cardiac activity, MS-222 was not utilized in e following experiments. Fig. 3. e anes etic MS-222 alters heart rate (HR.
