The following represents an email discussion in September 2005 on the topic of fish model systems for the study of evolution. The participants included scientists working on a range of fish model systems, including cavefish, Danios, sticklebacks, cichlids, and trout. Editing has been kept to a minimum, to maintain the character of the on-line discussion.

Building trophic specializations that result in substantial niche partitioning within a young adaptive radiation
TLDR
Overall, scale specialists showed the most divergent morphology, suggesting that selection for scale‐biting might be stronger or act on a greater number of traits than selection for either detritivory or durophagy.
Considering the zebrafish in a comparative context.

TLDR
A special issue on zebrafish biology is introduced that attempts to integrate developmental genetics with comparative studies of other fish species to provide an opportunity for synergy between communities using these two fundamentally different approaches.
Molecular cytogenetics of blind mexican tetra and comments on the karyotypic characteristics of genus Astyanax (Teleostei, Characidae).
TLDR
Chromosomal aspects of the genus Astyanax are discussed and a few pericentromeric heterochromatin regions were mainly constituted by GC, including the one from the Ag-NOR.

Adaptive evolution and explosive speciation: the cichlid fish model
The cost of DNA sequencing continues to fall, which makes it feasible to develop genomic resources for new model species that are well suited for studying questions in evolutionary biology. The…
The genetic architecture of divergence between threespine stickleback species
TLDR
A genome-wide linkage map is developed for the three-spined stickleback (Gasterosteus aculeatus), an extensively studied teleost fish that has undergone rapid divergence and speciation since the melting of glaciers 15,000 years ago.
Widespread Parallel Evolution in Sticklebacks by Repeated Fixation of Ectodysplasin Alleles
Major phenotypic changes evolve in parallel in nature by molecular mechanisms that are largely unknown. Here, we use positional cloning methods to identify the major chromosome locus controlling…
Genetic analysis of cavefish reveals molecular convergence in the evolution of albinism
TLDR
The generation of a genome-wide linkage map is described to allow quantitative trait analysis of evolutionarily derived morphologies in the Mexican cave tetra, a species that has, in a series of independent caves, repeatedly evolved specialized characteristics adapted to a unique and well-studied ecological environment.
Tetraodon fluviatilis, a new puffer fish model for genome studies.
TLDR
A T. fluviatilis cDNA library is constructed and characterized to facilitate and extend the use of the puffer fish as a model for genome studies, and phylogenetic analysis placed both fishes at the base of the Perciformes lineage.
Integration and evolution of the cichlid mandible: the molecular basis of alternate feeding strategies.
TLDR
It is concluded that patterns of morphological integration of the cichlid jaw reflect a balance among conflicting functional demands and has the potential to alter mandibular morphology in a way that mimics adaptive variation among fish species.
Production of clones of homozygous diploid zebra fish (Brachydanio rerio)
TLDR
Clones of homozygous fish have been produced from individual homozygotes and associated genetic methods facilitate genetic analyses of this vertebrate.

Parallel genetic basis for repeated evolution of armor loss in Alaskan threespine stickleback populations.
TLDR
Rapid and repeated armor loss in Alaskan stickleback populations appears to be occurring through the fixation of large-effect variants in the same genes, implicating the same Mendelian armor reduction genes.
The Genetic Architecture of Parallel Armor Plate Reduction in Threespine Sticklebacks
TLDR
It is suggested that a small number of genetic changes can produce major skeletal alterations in natural populations and that the same major locus is used repeatedly when similar traits evolve in different locations.
