“…This may be that the level of essential fatty acids (EFAs) present in both FO and VO diets was sufficient enough for normal spermatogenesis in gilthead seabream [ 26 ]. The dietary ARA, EPA and DHA levels used here were found to be more or less at the same level than in studies with other fish species such as European sea bass [ 88 ], Senegalese sole [ 86 ], rainbow trout [ 89 ], European eel [ 90 ], Siberian sturgeon [ 91 ] or Eurasian perch [ 92 ].…”

Genetic selection in gilthead seabream (GSB), Sparus aurata, has been undertaken to improve the growth, feed efficiency, fillet quality, skeletal deformities and disease resistance, but no study is available to delineate the effect of genetic selection for growth trait on GSB reproductive performance under mass spawning condition. In this study, high growth (HG) or low growth (LG) GSB broodstock were selected to evaluate the sex steroid hormones, sperm, egg quality and reproductive performance under different feeding regime of commercial diet or experimental broodstock diet containing either fish oil (FO) or vegetable oil (VO) based diet. Under commercial diet feeding phase, broodstock selected for either high growth or low growth did not show any significant changes in the egg production per kg female whereas egg viability percentage was positively (p = 0.014) improved by the high growth trait broodstock group. The experimental diet feeding results revealed that both growth trait and dietary fatty acid composition influenced the reproductive performance of GSB broodstock. In the experimental diet feeding phase, we observed high growth trait GSB males produced a higher number of sperm cells (p < 0.001) and also showed a higher sperm motility (p = 0.048) percentage. The viable egg and larval production per spawn per kg female were significantly improved by the broodstock selected for high growth trait and fed with fish oil-based diet. This present study results signifies that gilthead seabream broodstock selected on growth trait could have positive role in improvement of sperm and egg quality to produce viable progeny.

“…PUFA are particularly important for fish since deficiencies in these compounds may cause a general deterioration of fish health, poor growth, low feed efficiency and often high mortality 21 – 23 . Previous studies demonstrated that a proper PUFA dietary content is essential to sustain both larval and adult Siberian sturgeon growth and welfare 24 , 25 ; these compounds play a pivotal role in sturgeon’s fillet and caviar quality 26 .…”

Over the last years, the potential use of Black Soldier Fly meal (BSF) as a new and sustainable aquafeed ingredient has been largely explored in several fish species. However, only fragmentary information is available about the use of BSF meal-based diets in sturgeon nutrition. In consideration of a circular economy concept and a more sustainable aquaculture development, the present research represents the first comprehensive multidisciplinary study on the physiological effects of a BSF diet during sturgeon culture in an aquaponic system. Siberian sturgeon (Acipenser baerii) juveniles were fed over a 60-days feeding trial on a control diet (Hi0) and a diet containing 50% of full-fat BSF meal respect to fish meal (Hi50). Physiological responses of fish were investigated using several analytical approaches, such as gas chromatography-mass spectrometry, histology, Fourier Transformed Infrared Spectroscopy (FTIR), microbiome sequencing and Real-time PCR. While aquaponic systems performed optimally during the trial, Hi50 group fish showed lower diet acceptance that resulted in growth and survival reduction, a decrease in hepatic lipids and glycogen content (FTIR), a higher hepatic hsp70.1 gene expression and a worsening in gut histological morphometric parameters. The low feed acceptance showed by Hi50 group sturgeon highlighted the necessity to improve the palatability of BSF-based diet designed for sturgeon culture.

“…Their role has been investigated in larvae of several sturgeon species, such as white sturgeon (Acipenser transmontanus) (Gawlicka, Herold, Barrows, Noüe, & Hung, 2002), Russian sturgeon (Acipenser gueldenstaedtii) (Sener, Yildiz, & Savaş, 2005) and Persian sturgeon (Acipenser persicus) (Hosseinpour et al, 2010), where these fatty acids were identified as an essential element to guarantee an optimal survival rate. In recent studies Luo et al (2015) and Luo et al (2017) demonstrated that a correct inclusion of essential fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in broodstock diets showed a positive effect on reproductive performances and larval survival of Siberian sturgeon, underlining the importance of fatty acids in broodstock and larval metabolism. It has been demonstrated that high stocking densities may affect some metabolic pathways, such as those associated to the lipid metabolism.…”

Effects of stocking density on reared Siberian sturgeon (Acipenser baerii) larval growth, muscle development and fatty acids composition in a recirculating aquaculture system

This study evaluated the effects of rearing density on muscle growth and development in Siberian sturgeon (Acipenser baerii) larvae. Three different stocking densities were tested: low (LD, 30 larvae/l), mid (MD, 80 larvae/l) and high (HD, 150 larvae/l) in a recirculating aquaculture system. Larvae were sampled at hatching (T0), schooling (T1) and complete yolk-sac absorption (T2) stage and were weighed and processed for muscle tissue histometrical analyses and for qualitative morphological study analyses; fatty acid profile was also determined by Gas Chromatography-Flame Ionization Detector analysis. Low-density larvae presented a higher weight than MD or HD at T2 (p < 0.05). Histometrical analysis revealed that total muscle area was similar at T1 and T2, but higher than T0, while it was lower at HD at schooling (p < 0.05). The fatty acid profile revealed no differences between densities while, during development, there was a selective consumption: sparing or increasing of essential fatty acids to the detriment of their precursors. Our study suggests that lower densities appear to be more suitable to rear Siberian sturgeon in this particular stage of development. Indeed, larvae reared at the lower density were heavier and longer while larvae reared at the higher density showed lower muscle proliferation rate. As a consequence, LD larvae may exert an increase of potential growth at a mid-long term.

In 1998, all sturgeon species were effectively added to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which allowed to control the illegal trade of sturgeons and their products and the implementation of conservation plans.Survival and growth during early stages of development of Siberian sturgeon and throughout the following life periods is of great importance both for conservation aquaculture production programs and for commercial purposes. Following an increased demand of commercial production facilities, there is a growing need for the improvement of hatchery technologies that allow the production of high quality Siberian sturgeon larvae. After hatching, only endogenous feeding occurs (Balon, 2001), when larvae entirely rely on the yolk-sac reserves for energy and growth, until its digestive system is
