The sterlet (Acipenser ruthenus) in the middle Danube: What are the causes of the average weight increase?

open access: yesFrontiers in Marine Science, 2015
The sterlet is the last regularly documented native sturgeon species in the Slovak-Hungarian stretch of the middle Danube. The current status of the species is generally unknown because there is lack of the data.

Identification of metallothionein gene structure in sterlet (Acipenser ruthenus)

open access: yes, 2017
Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against adverse effects of these ions and their compounds.

Induced spermiation in 3-year-old sterlet, Acipenser ruthenus L.

open access: yesAquaculture Research, 2004
AbstractSpermiation in 3-year-old sterlet, Acipenser ruthenus(L.), males maintained under warmwaterconditionswas induced by intramuscular injection of either (i)(D-Ala 6 )-GnRH-ProNHEt (Kobarelin); (ii) mamma-lian GnRH analogue1metoclopramide (Ovopel); or(iii) human chorionic gonadotropin (Biogonadyl).The volume of milt, sperm concentration and mo ...

To the structure of the spinal cord in sterlets

open access: yesNeurology Bulletin, 2020
In this session, we will allow ourselves to report the observations made in the laboratory and the highly respected teacher, prof. N.A.Mislavsky, on the structure of the spinal cord in sterlets.Our communication will be reduced, mainly, to the description of: 1) neuroglia cells, 2) ependyma cells and 3) nerve cells with the help of the substance.

The use of biofilters with different types of fillers in recirculation aquatic system (RAS)

open access: yesFisheries & Aquatic Life
The aim of this study was to evaluate the effectiveness of using highly porous materials as fillers for biofilters in RAS, such as those with a much higher specific surface area than classical polymer floating bioload, and to determine the optimal ...
