The dwarf neon rainbowfish Melanotaenia praecox, a small spiny-rayed fish with potential as a new Acanthomorpha model fish: I. Fin ray ontogeny and postembryonic staging
Background
Fish fins with highly variable color patterns and morphologies have many functions. In Actinopterygii, the free parts of fins are supported by “soft rays” and “spiny rays.” Spiny rays have various functions and are extremely modified in some species, but they are lacking in popular model fish such as zebrafish and medaka. Additionally, some model fish with spiny rays are difficult to maintain in ordinary laboratory systems.
Results
Characteristics of the small, spiny-rayed rainbowfish Melanotaenia praecox render it useful as an experimental model species. Neither fish age nor body size correlate well with fin development during postembryonic development in this species. A four-stage developmental classification is proposed that is based on fin ray development.
Conclusions
Melanotaenia praecox is an ideal species to rear in laboratories for developmental studies. Our classification allows for postembryonic staging of this species independent of individual age and body size. Development of each fin ray may be synchronized with dorsal fin development. We discuss the differences in mechanisms regulating soft, spiny, and procurrent ray development.
期刊介绍:
Developmental Dynamics, is an official publication of the American Association for Anatomy. This peer reviewed journal provides an international forum for publishing novel discoveries, using any model system, that advances our understanding of development, morphology, form and function, evolution, disease, stem cells, repair and regeneration.
