Sperm Lipid Composition in Early Diverged Fish Species: Internal vs. External Mode of Fertilization

open access: yesBiomolecules, 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 ...

Effects of Attractants on the Growth Performance, Antioxidant Capacity, Immunity, and Histology of Largemouth Bass Larvae (<i>Micropterus salmoides</i>). [PDF]

open access: yesAquac Nutr
This 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

Restoration and ecology of sterlets in the Austrian Danube – The way from LIFE-Sterlet to LIFE-Boat-4-Sturgeon

open access: yes, 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 ...

Development of cryoprotective media for low-temperature freezing of sterlet (Acipenser ruthenus) sperm

open access: yesRibogospodarsʹka Nauka Ukraïni, 2017
Purpose. To develop the optimum composition of a cryoprotective solution for freezing sterlet sperm with the use of new and standard constituents and compare the results of the fertilization of eggs with sperm frozen by different ways and in different ...

The effects of polyculture on behaviour and production of pikeperch in recirculation systems

open access: yesAquaculture 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 ...

The Polyculture of Sterlet (Acipenser ruthenus) and Carp (Cyprinus carpio) in Recirculating Aquaculture Systems. The Effects on Fish Growth Dynamic and Production

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The polyculture of two or more fish species is very common in ponds, this fish culture technique being relatively newly applied in recirculating aquaculture systems (RAS).

Draft Genome and Complete Hox-Cluster Characterization of the Sterlet (Acipenser ruthenus)

open access: yesFrontiers in Genetics, 2019
Background: Sturgeons (Chondrostei: Acipenseridae) are a group of “living fossil” fishes at a basal position among Actinopteri. They have raised great public interest due to their special evolutionary position, species conservation challenges, as well as

Enrichment in a Fish Polyculture: Does it Affect Fish Behaviour and Development of Only One Species or Both?

open access: yesApplied Sciences, 2022
Physical enrichment of structures has been used for the last decades in aquaculture to improve fish production and welfare. Until now, this enrichment has been practiced in fish monoculture but not in fish polyculture.

Long-term changes of sterlet (Acipenser ruthenus) population in the Hungarian section of the Danube [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2009
Sturgeons had played an important role in the history of Hungarian fisheries, but due to over-fishing, followed by extensive river regulations and deterioration of habitats, there has been a considerable decrease in populations which are now on the verge
