, 2022 Sturgeons are an essential faunal element of the Danube and provided a link between the Alpine Danube basin and the Black Sea through their migration in the past. Today, two out of six Danube sturgeons are already regionally extinct, and the remaining species are threatened with extinction due to poaching, bycatch, migration barriers and habitat loss ...

Sperm Lipid Composition in Early Diverged Fish Species: Internal vs. External Mode of Fertilization
Biomolecules, 2020 The lipid composition of sperm membranes is crucial for fertilization and differs among species. As the evolution of internal fertilization modes in fishes is not understood, a comparative study of the sperm lipid composition in freshwater ...

The effects of polyculture on behaviour and production of pikeperch in recirculation systems
Aquaculture Reports, 2020 Recirculating aquaculture systems (RASs) are seen as a promising technology to address the societal and environmental challenges of aquaculture. However, this technology is mainly used in intensive monoculture and little knowledge is available in ...

Effects of Attractants on the Growth Performance, Antioxidant Capacity, Immunity, and Histology of Largemouth Bass Larvae (<i>Micropterus salmoides</i>). [PDF]
Aquac NutrThis study evaluated the effect of four attractants on the growth performance, antioxidant capacity, immunity, and histology of largemouth bass larvae (Micropterus salmoides). A total of 75,000 larvae (~1.25 mg) were randomly divided into 15 tanks (five groups with three replicates), with 5000 larvae per tank. The experimental diets were isonitrogenous

Potential Mechanisms of Dietary Potassium Diformate and Sodium Propionate Driving Intestinal Microbiota and Lipid Metabolites to Modulate Intestinal Health of <i>Trachinotus ovatus</i>. [PDF]
Aquac NutrThis study aims to investigate the effects of potassium diformate (KDF) and sodium propionate (NaP) on gut digestive and immune functions, intestinal microbiota, and lipid metabolites of Trachinotus ovatus based on multiomics approach. Juvenile T. ovatus (initial weight: 8.65 ± 0.02 g) were subjected to a 56‐day feeding regimen.

Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]
, 2020 Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

Cryopreservation of common carp sperm [PDF]
, 2003 Experiments were carried out to investigate the effect of five extenders (sucrose, glucose, fructose, KCl and a saline carp sperm extender) and two cryoprotectants (dimethyl-sulfoxide (DMSO) and methanol) on the cryopreservation of common carp sperm ...
