The effects of seasonal, sex and size on the digestive enzyme activities in freshwater crayfish (Astacus leptodactylus Eschscholtz, 1823)
(Wiley, 2018)
The effects of seasonal, sex and size on digestive enzyme activities of Astacus leptodactylus in natural habitat were investigated in the present study. The freshwater crayfish were sampled 584 individual as seasonally ...
Evaluation of mealworms (Tenebrio molitor) meal as an alternative protein source for narrow-clawed crayfish (Pontastacus leptodactylus) juveniles
(Wiley, 2021)
An eighty-day feeding study was performed to investigate the effects of mealworm meal (Tenebrio molitor) on the growth, survival and moulting frequency of juvenile Narrow-clawed crayfish (Pontastacus leptodactylus). Three ...
Cryoprotective Effect of Vitamin E Supplementation of Different Extenders on Quality and Fertilizing Ability of Frozen-Thawed Brown Trout Sperm
(Mary Ann Liebert Inc., 2021)
Vitamin E is one of the most powerful antioxidants for prevention of cell damage resulting from cryopreservation, but its efficacy for cryopreserving brown trout sperm is still unclear. In this work, the protective effect ...
Heavy metal bioaccumulation, oxidative stress and genotoxicity in African catfishClarias gariepinusfrom Orontes river
(Springer, 2020)
One of the major problems affecting the ecosystem health is the exposure of heavy metals due to anthropogenic activities. These exposures may induce toxiogenetic damage and carcinogenesis in aquatic organism. DNA damage ...
Testicular germ line cell identification, isolation, and transplantation in two North American catfish species
(Springer, 2018)
Our aim was to transplant blue catfish germ line stem cells into blastulae of triploid channel catfish embryos to produce interspecific xenogenic catfish. The morphological structure of the gonads of blue catfish (Ictalurus ...
Effect of Extender Supplemented With Boron on Post-Thaw Motility, Viability, DNA Damage and Fertilization Ability of Cryopreserved Brown Trout (salmo trutta macrostigma) Spermatozoa
(Cryo Letters, 2019)
BACKGROUND: Boron has been considered as an essential nutrient for decreasing lipid peroxidation and improving antioxidant mechanism in different animal species. On the other hand, its effect on quality or DNA damage ...
Isolation, culture and bacterial contamination of oogonial stem cells of Brown trout, Salmo trutta macrostigma (Dumeril, 1858)
(Indian Journal of Experimental Biology, 2021)
Increased commercial value of brown trout, Salmo trutta macrostigma has lead to its declined natural stock due to over exploitation, and thereby made it an endangered species. Cryopreservation of spermatogonial and oogonial ...
Effect of dietary modified zeolite (clinoptilolite) on growth performance of gilthead sea bream (Sparus aurata) in the recirculating aquaculture system
(Wiley, 2021)
In this study, the effects of six different dietary levels of commercial surface-modified clinoptilolite (Minazel Plus(R) [MP]; 0, 1, 1.5, 2, 2.5 and 3 g kg(-1)) were observed for fingerling gilthead sea bream in recirculating ...
Evaluaton of genotoxic potental induced by marine cage culture
(Iran Solid Waste Association, 2021)
BACKGROUND AND OBJECTIVES: The eutrophication process is increased by anthropogenic or aquaculture facilites in marine ecosystems. DNA damage biomarkers for fish species detect genotoxic parameters for ecological risk ...
Effects of serotonin (5-HT) on juvenile culture of narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823)
(Wiley, 2021)
Serotonin was used for the first time in this study as a feed additive in juvenile freshwater crayfish Pontastacus leptodactylus, (stage II-V) to investigate its effects on growth performance, survival and immune response ...
