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

The Research Advances in Distant Hybridization and Gynogenesis in Fish

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Distant hybridization and gynogenesis are two prevalent breeding techniques for fishes. Drawing from the research achievements of our team and the existing literature, we summarize the reproductive traits and genetic features of fishes derived from distant hybridizations and gynogenesis, and we deduce the fundamental mechanisms of these two ...

Potential Mechanisms of Dietary Potassium Diformate and Sodium Propionate Driving Intestinal Microbiota and Lipid Metabolites to Modulate Intestinal Health of Trachinotus ovatus

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
This 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.

Effects of Attractants on the Growth Performance, Antioxidant Capacity, Immunity, and Histology of Largemouth Bass Larvae (Micropterus salmoides)

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
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

Development of DNA identification for sturgeon species with the use of real time polymerase chain reaction

open access: yesRibogospodarsʹka Nauka Ukraïni, 2017
Purpose. Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. Four species may now be extinct.

Sperm Quality, Milt Biochemistry, and Cellular Ultrastructure in Fresh and Cryopreserved Sperm of Brycon amazonicus

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.

Sperm Quality, Seminal Characteristics, and Their Relationship in the Bulatmai Barbel (Luciobarbus capito) Following First and Second Stripping During the Breeding Season

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
The present study investigated the effects of multiple sperm collections on sperm quality, seminal plasma ionic and biochemical parameters, and the relationship between measured variables in the Bulatmai barbel (Luciobarbus capito) during the breeding season.
