Natural Biota’s Contribution to Cultured Aquatic Animals’ Growth in Aquaculture Cannot Be Ignored

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets.

Cytology, function and dynamics of stem and progenitor cells in decapod crustaceans

open access: yesBiological Reviews, Volume 97, Issue 2, Page 817-850, April 2022., 2022
ABSTRACT Stem cells play key roles in development, tissue homeostasis, regeneration, ageing and diseases. Comprehensive reviews on stem cells are available for the determinately growing mammals and insects and some lower invertebrates like hydra but are rare for larger, indeterminately growing invertebrates that can live for many decades.

Recent developments in male fertility evaluation, sperm cryopreservation and artificial fertilisation, and their potential application to decapod crustacean aquaculture

open access: yesReviews in Aquaculture, Volume 14, Issue 2, Page 848-889, March 2022., 2022
Abstract To maximise productivity, a better understanding of the underlying causes of subfertility that lead to inferior offspring and high mortality is imperative. In decapod crustaceans, most research has focused on female reproductive performance, with little attention given to male fertility.

The redclaw crayfish: A prominent aquaculture species with invasive potential in tropical and subtropical biodiversity hotspots

open access: yesReviews in Aquaculture, Volume 13, Issue 3, Page 1488-1530, June 2021., 2021
Abstract The redclaw crayfish (Cherax quadricarinatus; hereafter redclaw), native to northern Australia and southern New Guinea, is among the largest freshwater decapods. It matures early and is considered highly prolific as females may lay over one thousand eggs in a single clutch.

Fecundity of the narrow-clawed crayfish Pontastacus leptodactylus in the water bodies of Belarus

open access: yesProceedings of the National Academy of Sciences of Belarus, Biological Series, 2023
Pre-larvae hatching fecundity and ovarian fecundity of narrow-clawed crayfish populations were estimated in the lakes and reservoirs of Belarus. Statistically significant differences in the fecundity of females from various water bodies were noted only for Lake Kichino.
