Zebrafish and other small laboratory fishes are emerging as important animal models for investigating human skeletal development and diseases. In recent years, there has been a notable increase in research publications employing x-ray radiography and micro-computed tomography to analyze the skeletal structures of these animals. However, evaluating bone morphology and mineral density in small laboratory fish poses unique challenges compared to well-established small rodent models. The varied approaches to image acquisition, analysis, and reporting across studies have led to substantial obstacles in interpreting and comparing research findings. This article addresses the urgent need for standardized reporting of parameters and methodologies related to image acquisition and analysis, as well as the adoption of harmonized nomenclature. Furthermore, it offers guidance on anatomical terminology, units of measurement, and the establishment of minimal parameters for reporting, along with comprehensive documentation of methods and algorithms used for acquisition and analysis. We anticipate that adherence to these guidelines will enhance the consistency, reproducibility, and interpretability of reported measurements of bone density and morphometry in small fish models. These advancements are vital for accurately interpreting phenotypes and gene functions, particularly in the context of multi-center studies.
