Abstract
Cytogenetic studies in marine fish are scarce, and elemental cytogenetic information is available for not >2% of the species. Traditional cytogenetic methods require living individuals for their application, making the analysis of marine ichthyofauna very difficult. In this study, we present a detailed new protocol to obtain cytogenetic preparations from marine fish, through access to specimens in postmortem condition. The application of this protocol made it possible to access elemental cytogenetic information (diploid number) in six native species of the South Pacific Ocean, representative of five orders. In this way, we provide a new low-cost methodological tool for focused or large-scale cytogenetic analysis, both in economically important, native, or threatened species.
期刊介绍：
Zebrafish is the only peer-reviewed journal dedicated to the central role of zebrafish and other aquarium species as models for the study of vertebrate development, evolution, toxicology, and human disease.
Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies. While genetically more distant from humans, the vertebrate zebrafish nevertheless has comparable organs and tissues, such as heart, kidney, pancreas, bones, and cartilage.
Zebrafish introduced the new section TechnoFish, which highlights these innovations for the general zebrafish community.
TechnoFish features two types of articles:
TechnoFish Previews: Important, generally useful technical advances or valuable transgenic lines
TechnoFish Methods: Brief descriptions of new methods, reagents, or transgenic lines that will be of widespread use in the zebrafish community
Zebrafish coverage includes:
Comparative genomics and evolution
Molecular/cellular mechanisms of cell growth
Genetic analysis of embryogenesis and disease
Toxicological and infectious disease models
Models for neurological disorders and aging
New methods, tools, and experimental approaches
Zebrafish also includes research with other aquarium species such as medaka, Fugu, and Xiphophorus.
