As a way of introduction, I do chemical genetics of zebrafish early development. https://medschool.vanderbilt.edu/chaz-hong-lab /
Briefly, in a manner analogous to classic mutagenesis screens, we conduct high-throughput chemical screens using zebrafish to discover small molecules that specifically perturb embryonic pattern formation. Using the interdisciplinary chemical genetic approach, we have discovered exquisitely selective modulators of the Bone Morphogenetic Protein (BMP), Wnt and Hedgehog pathways, as well as important new signaling components that direct early vertebrate development. For example, I discovered dorsomorphin, the first small molecule inhibitor of BMP signaling. The technology from this effort is nearing an Investigational New Drug (IND) stage for several devastating human diseases, such as fibrodysplasia ossificans progressiva, and incurable pediatric cancers.
Importantly, from this effort, we also have discovered many compounds that have really interesting effects on zebrafish embryos, but we don’t know the mechanism of action. I hope to initiate a “crowd sourcing” to accelerate discovery and translation.
Please do not hesitate to contact me with questions about this effort and how it might benefit the zebrafish community. I look forward to hearing from you.

Each human gene annotated on the Santa Cruz site was compared by BLAST against the Sanger Institute zebrafish genome sequence. These data can be used to help identify zebrafish orthologues of human or Fugu genes.
MGH site provides a BLAST search of a gene or marker of interest to the assembled sequence contigs of the zebrafish genomic shotgun sequence from the Sanger project.
Centralized site for all meiotic and radiation hybrid maps of the zebrafish genome.
MGH site offers this tool which searches for a supercontig, scaffold, or finished BAC clone by name or accession number, derives all di- and tri- nucleotide repeat sequences in the supercontig, masks the sequence around the repeats for larger zebrafish repetitive sequences and then designs unique sequence primer pairs to amplify the simple sequence repeats. These are potentially polymorphic simple sequence repeats (SSRs) that can be used in genetic mapping/positional cloning projects. This site also offers a tool to search for marker primer pairs by chromosome coordinates (3MB chromosome segments max.)
The qPrimerDB database (real-time quantitative PCR Primer Database), https://biodb.swu.edu.cn/qprimerdb) is the most comprehensive qPCR primer database available to date, with a web front-end providing gene-specific and pre-computed primer pairs across 516 important organisms, including human, mouse, zebrafish, yeast, thale cress, rice, and maize. The qPrimerDB provides an interactive and information-rich web graphical interface to display search and BLAST results as table-based descriptions and associated links. In this database, we provide 9,273,735 of the best primer pairs for each gene based on primer pair coverage (PPC), as well as 68,653,054 alternative gene-specific primer pairs, which can be conveniently batch downloaded. We validated the specificity and efficiency of the qPCR primer pairs for 66 randomly selected genes in six different organisms through qPCR assays and gel electrophoresis. The qPrimerDB database represents a valuable, timesaving resource for gene expression analysis. This resource, which will be updated routinely.
The Trans-NIH Zebrafish Genome Initiative at Children's Hospital Boston aims to annotate zebrafish genes with human known genes for functional and comparative studies. This website provides a web service for retrieving annotated zebrafish genes represented on Affymetrix Zebrafish Genome Arrays and Roche-NimbleGen Zebrafish Expression Arrays to the research community.
The Norwegian Microarray Consortium offers their array products for academic use to customers world wide. One limitation is oligonucleotide arrays, which cannot provided to users in the US and Japan, due to licensing conditions. A moderate license fee will be added to the base price for oligonucleotide arrays sold to users in the UK, France, Germany, Italy, Austria, Belgium, Sweden, Switzerland, Luxembourg, and The Netherlands.
NIH initiative for production of full length sequences and cDNA clones.
1819 ZGC clones recloned in pENTR223.1 In May 2008, ZGC has added 1819 full length ZGC clones recloned into a Gateway Entry vector (pENTR223.1;) for expression analysis and other applications.
These clones can be found by searching Entrez nucleotide for "NIH_ZGC_36".
The DFCI Zebrafish Gene Index (ZGI) integrates research data from international zebrafish gene research projects and represents a non-redundant view of all zebrafish genes and data on their expression patterns, cellular roles, functions, and evolutionary relationships.
This database consists of 4694 contigs or singletons obtained from ~18000 reads of cDNAs that were isolated from the microdissected otocysts of zebrafish embryos at 20-30 hours postfertilization, following subtraction with a pool of liver cDNAs from adult fishes.

This project seeks to identify, phenotype and distribute a large number of mutant zebrafish lines. Mutations are identified from populations of chemically mutagenised animals using PCR of specific exons followed by re-sequencing. Mutants are analysed for morphological and molecular differences and distributed to the community. This is an open resource and is now open to requests from the community. The Zebrafish Mutation Resource Tracking page lists the mutants generated by the Sanger Zebrafish Mutation Resource and the ZF-HEALTH consortium.

E-CRISP is a software tool to design and evaluate target sites for use with the Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) system. The web application uses fast algorithms to identify sgRNA target sequences in any nucleotide sequence for use in CRISPR/Cas mediated genome editing. E-CRISP analyzes target specificity of the putative designs and assesses their genomic context (e.g. exons, transcripts, CpG islands). The design process incorporates different options of how CRISPR constructs can be used in experimental applications
E-TALEN is a web service to design TALENs for introducing knock-out mutations, for endogenous tagging and targeted excision repair. The tool can be used to design TALENs against a single target but also for up to 50 target genes in parallel. E-TALEN guides the user through end-to-end de-novo design process for specific sequences or genomic loci. In addition, it can also be used to evaluate existing TALEN designs.
