Rozynski R, Dobosz S, Rozynski M, Ocalewicz K
Animals (Basel) . 2025 Feb; 15(4). PMID: 40002963
Sterile triploid European graylings () could serve as an alternative to allochthonous stocking, potentially protecting native populations from genetic introgression. In this study, two-year-old triploid and diploid graylings were examined...

Kucinski M, Trzeciak P, Pirtan Z, Jozwiak W, Ocalewicz K
Anim Reprod Sci . 2024 Dec; 272:107659. PMID: 39631249
The phenotype, genetic sex ratio and gonadal development characteristics were evaluated in randomly selected juvenile (15 months old), sub-adult (22 months old) and adult (30 months old) triploid hybrids of...

Ocalewicz K, Kucinski M, Jasielczuk I, Gurgul A, Kucharski M, Dobosz S
J Appl Genet . 2024 Jun; 65(4):897-905. PMID: 38922511
Expression of the telomerase reverse-transcriptase (TERT) gene and activity of telomerase have been reported in the somatic tissues and gonads in fish irrespective of their age and size. Nevertheless, little...

Panasiak L, Kucinski M, Hliwa P, Pomianowski K, Ocalewicz K
Cells . 2023 Jul; 12(13). PMID: 37443805
Telomerase activity has been found in the somatic tissues of rainbow trout. The enzyme is essential for maintaining telomere length but also assures homeostasis of the fish organs, playing an...

Ocalewicz K
Fish Physiol Biochem . 2023 Jun; 50(5):1947-1957. PMID: 37296321
Induced development of haploid embryos (H) with only paternal (androgenesis) or maternal (gynogenesis) chromosomes requires irradiation of eggs before fertilization or activation of eggs with irradiated spermatozoa, respectively. To provide...

Kucinski M, Jakubowska-Lehrmann M, Gora A, Mirny Z, Nadolna-Altyn K, Szlinder-Richert J, et al.
Animals (Basel) . 2023 May; 13(9). PMID: 37174485
The European flounder (), which is closely related to the recently discovered Baltic flounder (), is currently the third most commercially fished species in the Baltic Sea. According to the...

Panasiak L, Kucinski M, Blaszczyk A, Ocalewicz K
Zebrafish . 2022 Jul; 19(4):131-136. PMID: 35867071
Role of telomerase in specimens with retarded growth (dwarfs) has not been thoroughly examined to date. Considering that some of the fish species show correlation between somatic growth and activity...

Hliwa P, Panasiak L, Ziomek E, Rozynski R, Leonowicz L, Grudniewska J, et al.
Anim Reprod Sci . 2022 Feb; 237:106929. PMID: 35101726
Use of parental individuals from allochthonous lineages to produce stocking specimens resulted in genetic contamination of many local European grayling (Thymallus thymallus) populations. Stocking programs including triploid individuals that are...

Panasiak L, Szubert K, Polonis M, Ocalewicz K
J Appl Genet . 2021 Nov; 63(1):133-139. PMID: 34775545
Somatic growth is considered to affect pace of the telomere attrition in vertebrates. As normally developed and dwarf fish differ in the body size we have decided to compare telomere...
