3
Genus Characteristics
Communal Tolerant of a range of water quality Small Easy to breed Pet quality
4
Characteristics of B. rerio
Family: Cyprinidae (Carps & minnows) Origin: India, Peninsula India, Ganges Basin - Up to Nepal Size: 5cm
5
Characteristics of B. rerio
Slow moving streams and still waters such as rice paddies and ponds. Found in groups in open areas at the surface.
6
Characteristics of B. rerio
Abiotic preferences: pH: dH: temperature:18-24°C
7
Genetic Background Gametes can be stripped easily and non-invasively for in vitro fertilization where haploid, triploid or homozygous diploid fish can be produced. Can be used directly in studies of gene interactions with environmental agents
8
Genetic Background Established model for vertebrate developmental genetics and the production of transgenic fishes. Can be stocked in high densities
9
Gentic Information Best mapped genome of any aquatic vertebrate and its complete genome will be completed mid-2002 by the Sanger Institute in the UK.
10
Embryonic Development
Emerging species of choice for genetic studies Visible embryos Fully mapped genome nervous system takes place very early
11
Life Cycle Reaches sexual maturity in as little as 60 days
Females can lay several hundred eggs per day. understanding normal and abnormal human development. Similarity to mammalian embryogenesis
12
Other Benefits Potential to produce altered specimens with specific traits Provides raw system for high through-put toxicological assays

From: PATRICIA EDWARDS To: Zebrafish Publications Coordinator Subject: Use of zebrafish in high school labs There seems to be an increasing amount of interest in using the zebrafish as a model in the study of vertebrate development and genetics in high school and even elementary school classes and labs. I have begun to keep a list of those who are active or interested in planning such a curriculum so that when I get inquiries I can forward them on those who are also doing that type of work. It can also be used by the participants as a means to network with other teachers. If you would like to be included on the list and have not already contacted me about it within the past week, please let me know. Be sure to include your full mailing address, phone & FAX numbers, and address. Current K-12 zebrafish resource list. Thanks for your help.
