The aim of this study was to assess the effect of different light intensities and photoperiods on growth, survival, and the yolk sac absorb of the Persian sturgeon, Acipenser persicus, larvae. Larvae were reared from hatching to yolk sac absorb (eight days) at four light intensities (0, 50, 150 and 300 lux) and three photoperiods (00L:24D, 12L:12D and 24L:00D) which consisted of seven treatment...

Lake sturgeon (Acipenser fulvescens) is a species of conservation concern that has been stocked in several Great Lakes (North America) rivers. were extirpated the Ontonagon River Superior and stocking began 1998. In 2017, gametes collected from spawning lake (9 females, 36 males) caught at nearby Sturgeon ground, generating nine family groups using 1:4 mating design (n = 862). 2018, 3 females 1...

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...

Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) experienced severe declines due to habitat destruction and overfishing beginning in the late 19(th) century. Subsequent to the boom and bust period of exploitation, there has been minimal fishing pressure and improving habitats. However, lack of recovery led to the 2012 listing of Atlantic sturgeon under the Endangered Species Act. Although ha...

Effects of Daphnia magna enriched with cod liver oil (CLO) as a source of highly unsaturated fatty acid (HUFA) on growth, survival, stress resistance, and fatty acid composition of the Persian sturgeon larvae were evaluated. Daphnia enriched for three different time periods (3, 6, and 9 hours) and non-enriched Daphnia were fed to the Persian sturgeon larvae (average weight 61.6±0.4mg) during 14...

Populations of sturgeon (Acipenseridae) are declining in many places in the world because of several potential factors, including overharvesting, habitat alteration, and pollution. In North America, populations of the white sturgeon (Acipenser transmontanus) have been experiencing poor annual recruitment in major river systems for more than three decades. Metal pollution has been hypothesized a...

Understanding potential limiting factors affecting population growth of the endangered pallid sturgeon, Scaphirhynchus albus, is important in upper (UMOR) and lower Missouri River (LMOR) basins. The UMOR upstream several reservoirs generally has more natural habitat features, whereas LMOR downstream these been channelized to support navigation. In both sections, sturgeon recruitment age-1 a con...

The present study aims at investigating muscle development and stress response in early stages of Siberian sturgeon when subjected to different rearing temperatures, by analysing growth and development of the muscle and by assessing the stress response of yolk-sac larvae. Siberian sturgeon larvae were reared at 16°C, 19°C and 22°C until the yolk-sac was completely absorbed. Sampling timepoints ...

A study was conducted to determine the relationships between egg and newly hatched larvae Ž . sizes and growth and survival of Siberian sturgeon Acipenser baeri during early stages of development. We hypothesised that this may lead to improved rearing techniques and hatchery Ž . management. Eggs mean size 2.8–4.1 mm were obtained from 20 cultured 13–14 years old Ž . females. There was a positiv...
