Agriculture, fisheries, and the food industry play a key role in ensuring country's security. The modern fishing Ukraine is highly industrial, capital-intensive, integrated production with high costs, which designed to ensure socio-economic development of many coastal regions provide population valuable protein products necessary for healthy eating. total volume extracted aquatic organisms III ...

Ryanodine (Ry) sensitivity of cardiac contraction differs between teleost species, between atrium and ventricle, and according to the thermal history of the fish. The hypothesis that variability in Ry sensitivity of contraction is due to species-specific, chamber-specific, and temperature-related differences in the sarcoplasmic reticulum (SR) Ca(2+) content, was tested by comparing steady-state...

The effects of sustained anoxia on cardiac electrical excitability were examined in the anoxia-tolerant crucian carp (Carassius carassius). The electrocardiogram (ECG) and expression of excitation-contraction coupling genes were studied in fish acclimatised to normoxia in summer (+18°C) or winter (+2°C), and in winter fish after 1, 3 and 6 weeks of anoxia. Anoxia induced a sustained bradycardia...

The crucian carp Carassius carassius (Linnaeus, 1758), is native to many European freshwaters. Despite its wide distribution, the crucian carp is declining in both the number and sizes of populations across much of its range. Here we studied 30 individuals of a putative pure population from Helsinki, Finland. Despite clear external morphological features of C. carassius, an individual was of a ...

The objective of this study was to investigate the effects of partially replacing fish meal with FMBH on the growth, digestive enzyme activity, and antioxidant capacity of allogynogenetic crucian carp. Fermented mushroom bran hydrolysate (FMBH) was prepared by enzymatic hydrolysis after the solid fermentation of mushroom bran (MB) inoculated with Ganodermalucidum and Saccharomyces cerevisiae. N...

The freshwater bivalve Anodonta woodiana is native to China and widely distributed in Asia, Europe, North America. However, natural populations of A. have dramatically declined recently. Several fish species been used as potential hosts breeding programs; nonetheless, the optimal host yet be identified. In this study, we examined suitability five (bighead carp, common crucian yellow catfish, ti...

BACKGROUND Retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) had been demonstrated to prime interferon (IFN) response against viral infection via the conserved RLR signaling in fish, and a novel fish-specific gene, the grass carp reovirus (GCRV)-induced gene 2 (Gig2), had been suggested to play important role in host antiviral response. METHODOLOGY/PRINCIPAL FINDINGS In this study,...

The first known tetraploid amniote that reproduces through parthenogenetic cloning by individual females is named and described. The species originated through hybridization between Aspidoscelis exsanguis (triploid parthenogen) 3 Aspidoscelis inornata (diploid bisexual or gonochoristic species) in the laboratory. We compared multivariate morphological variation between two lineages that arose f...
