“…Lake sturgeon that are used to enhance northern populations are typically reared at the Grand Rapids Fish Hatchery at 16 C with the potential for increasing rearing temperatures in the first year of life to increase growth rates and achieve larger sturgeon prior to release (Bugg et al, 2020). Recent studies have demonstrated that subtle changes in rearing temperature during early development can influence the growth and condition of lake sturgeon prior to a simulated overwintering event, which may influence survival rates (Brandt et al, 2022;Yoon et al, 2019Yoon et al, , 2020. However, there is little data available concerning the effects of exposures to elevated temperatures during early development on adaptive responses to cold during the first winter of life.…”

In Manitoba, Canada, wild lake sturgeon (Acipenser fulvescens) populations exist along a latitudinal gradient and are reared in hatcheries to bolster threatened populations.We reared two populations of lake sturgeon, one from each of the northern and southern ends of Manitoba and examined the effects of typical hatchery temperatures (16 C) as well as 60-day acclimation to elevated rearing temperatures (20 C) on mortality, growth and condition throughout early development. Additionally, we examined the cold shock response, which may be induced during stocking, through the hepatic mRNA expression of genes involved in the response to cold stress and homeoviscous adaptation (HSP70, HSP90a, HSP90b, CIRP and SCD). Sturgeon were sampled after 1 day and 1 week following stocking into temperatures of 8, 6 and 4 C in a controlled laboratory environment. The southern population showed lower condition and higher mortality during early life than the northern population while increased rearing temperature impacted the growth and condition of developing northern sturgeon. During the cold shock, HSP70 and HSP90a mRNA expression increased in all sturgeon treatments as stocking temperature decreased, with higher expression observed in the southern population. Expression of HSP90b, CIRP and SCD increased as stocking temperature decreased in northern sturgeon with early acclimation to 20 C. Correlation analyses indicated the strongest molecular relationships were in the expression of HSP90b, CIRP and SCD, across all treatments, with a correlation between HSP90b and body condition in northern sturgeon with early acclimation to 20 C. Together, these observations highlight the importance of population and rearing environment throughout early development and on later cellular responses induced by cold stocking temperatures.

“…As the environment during early life could significantly influence phenotypic development in lake sturgeon (Dammerman et al, 2015 ), metabolic rate data in this analysis were used from age‐0 lake sturgeon that were raised under the same environmental conditions of temperature (16°C), dissolved oxygen (100%), and without substrate in rearing tanks. The data analyzed here include previously published and unpublished data (Bugg et al, 2020 , 2023 ; Yoon et al, 2020 , 2021 ; Yoon, Amjad, et al, 2022 ; Yoon, Bugg, et al, 2022 ; Yoon, Deslauriers, & Anderson, 2019 ; Yoon, Deslauriers, Enders, et al, 2019 ; Yoon, Groening, et al, 2022 ; Yoon, Laluk, et al, 2022 ).…”

Environmental temperatures differ across latitudes in the temperate zone, with relatively lower summer and fall temperatures in the north leading to a shorter growing season prior to winter. As an adaptive response, during early life stages, fish in northern latitudes may grow faster than their conspecifics in southern latitudes, which potentially manifests as different allometric relationships between body mass and metabolic rate. In the present study, we examined if population or year class had an effect on the variation of metabolic rate and metabolic scaling of age‐0 lake sturgeon (Acipenser fulvescens) by examining these traits in both a northern (Nelson River) and a southern (Winnipeg River) population. We compiled 6 years of data that used intermittent flow respirometry to measure metabolic rate within the first year of life for developing sturgeon that were raised in the same environment at 16°C. We then used a Bayesian modeling approach to examine the impacts of population and year class on metabolic rate and mass‐scaling of metabolic rate. Despite previous reports of genetic differences between populations, our results showed that there were no significant differences in standard metabolic rate, routine metabolic rate, maximum metabolic rate, and metabolic scaling between the two geographically separated populations at a temperature of 16°C. Our analysis implied that the lack of metabolic differences between populations could be due to family effects/parental contribution, or the rearing temperature used in the study. The present research provided insights for conservation and reintroduction strategies for these populations of lake sturgeon, which are endangered or threatened across most of their natural range.

“…Optimization of the production requires extensive evaluation studies. Therefore, research on nutritional factors including feeding rates (Deng et al, 2003; Jafari et al, 2018), co‐feeding methods, feed particle sizes (Rónyai & Feledi, 2012), prey condition, and incubation method (Yoon et al, 2020), as well as research on culture conditions such as rearing temperature, appropriate water velocity (Mrnak et al, 2020; Poletto et al, 2018) and stocking density (Oprea & Oprea, 2009) are essential to overcome the bottlenecks and optimize the aquaculture production.…”

The effect of stocking density on sterlet Acipenser ruthenus (Linnaeus, 1758) larvae in the recirculating aquaculture system

The sterlet (Acipenser ruthenus) is a widely cultured sturgeon species due to its small body size, its relatively low rearing costs, early sexual maturation, and remarkable growth in the first 2 years (Prokeš et al., 2011).The success of sterlet culture fundamentally depends on the application of appropriate larval rearing protocol (Wegner et al., 2009). Difficulties like high mortality, low growth rate, occasions of cannibalism, overfeeding, bacterial infections, and weaning difficulties are regularly present during the larval period in sturgeons (Gisbert & Williot, 2002;Laczynska et al., 2020;Williot et al., 2018). These obstacles are associated with inadequate nutrition and/or unsuitable technological settings (Agh
