Summary

This dataset documents the length and developmental stage of pallid sturgeon and shovelnose sturgeon free embryos from the time of hatch through melanin plug expulsion (the approximate onset of exogenous feeding) reared in the laboratory at a constant temperature. Free embryos from 4 pallid sturgeon crosses and 7 shovelnose sturgeon crosses were reared separately in the laboratory at a mean temperature of 17.8 degrees Celsius (range 17.3–18.4 ). Beginning on the day of hatch, a minimum of three to six free embryos from each cross was randomly sampled and preserved in 10% neutral buffered formalin at 2 to 12-hour intervals, depending on age. Free embryos were microscopically examined and assigned a developmental stage (i.e., 36–45) [...]

Purpose

These data were collected as part of a study to document and characterize the growth and development of pallid sturgeon and shovelnose sturgeon free embryos from the time of hatch through melanin plug expulsion (the approximate onset of exogenous feeding). Documentation of the development and growth of pallid sturgeon and shovelnose sturgeon free embryos is essential to estimate the age of field collected specimens, develop free-embryo transport models, and improve the understanding of when and where successful spawning is occurring.
