The effects of larval rearing densities in White Sturgeon (Acipenser transmontanus)

By: Lenora Turcotte

White Sturgeon (Acipenser transmontanus) is increasingly becoming a species of interest in the Aquaculture industry. Producing juvenile sturgeon is one of the most difficult parts in the hatchery process, and high mortality rates are often experienced within the first 90 days. The primary objective of my undergraduate research is to determine the optimal density to maximize survivorship and/or survival rates in White Sturgeon culture. The secondary objective is to characterize the labour required in rearing at three different densities.

The experimental design is structured in triplicates under three different densities; low, medium and high. Live balances are recorded daily to measure survivorship over the time period and to calculate current feed rates based on total biomass. Weekly mean weight samples are taken to track the difference in growth of the juveniles which directly affects the density.  Finding a way to optimally culture juvenile White Sturgeon in terms of maximizing growth and survivorship has been strongly observed during the twelve week experiment.
