“…The aquaculture of U. unicinctus requires a higher stocking density because of a lack of adequate coastal space for this industry. Previous studies have demonstrated the effects of stocking density on several freshwater and marine species (Pei, Dong, Wang, Gao, & Tian, 2014; Shao et al, 2018; Wang et al., 2018). Higher stocking density can result in poor growth performance, lower survival rate and higher immune responses (Rahman et al., 2017; Shao et al., 2018).…”

Aquaculture of the Echiura worm Urechis unicinctus has developed rapidly in recent years. However, the artificial cultivation technology remains to be perfected. In this study, the effects of stocking density on the growth performance, physiological responses and intestinal microbiota of U. unicinctus juveniles were evaluated. Juvenile worms were randomly stocked at densities of 200 U (U. unicinctus/m3), 500 U, 1,000 U and 2,000 U, in aquariums. The results indicated that the contents of triglycerides, glucose, total cholesterol, lactic acid, alkaline phosphatase, acid phosphatase and aspartate transaminase in the coelomic fluid of U. unicinctus juveniles were significantly enhanced with increasing stocking density. The digestive enzyme activities increased with increasing stocking density from 200 U to 1,000 U, before exhibiting a significant decrease in the 2,000 U group. In contrast, the antioxidant capacity of U. unicinctus juveniles was suppressed under high stocking density conditions. In case of the intestinal microbiota of U. unicinctus juveniles, Actinobacteria were more abundant in the 200 U group; SJA15, Gluconobacter and OP81 were higher in the 1,000 U group; Burkholderiales and Limnohabitans were enriched in the 2,000 U group. The highest and lowest survival rates of the U. unicinctus juveniles were recorded in the 500 U and 200 U groups respectively, and high stocking densities negatively affected the individual growth performance. In summary, due to the highest survival rate and appropriate growth performance and physiological responses, 500 U was considered to be the optimal stocking density for the cultivation of U. unicinctus juveniles.

“…2 During the breeding process, it is commonly observed that approximately 15−30% of the crabs undergo precocious puberty and terminal molt, resulting in stagnation of body mass and higher mortality, which seriously affects production and economic benefits. 3 In addition to the influence of external conditions, 4,5 the intrinsic causes also have great effects on the development of individuals. As a carrier of properties of heredity, the male parent sperm is one of the determinants for offspring traits.…”

Sperm capacitation is broadly defined as a suite of biochemical and biophysical changes resulting from the acquisition of fertilization ability. To gain insights into the regulation mechanism of crustacean sperm capacitation, 4D label-free quantitative proteomics was first applied to analyze the changes of sperm in Eriocheir sinensis under three sequential physiological conditions: seminal vesicles (X2), hatched with the seminal receptacle content (X3), and incubated with egg water (X5). In total, 1536 proteins were identified, among which 880 proteins were quantified, with 82 and 224 proteins significantly altered after incubation with the seminal receptacle contents and egg water. Most differentially expressed proteins were attributed to biological processes by Gene Ontology annotation analysis. As the fundamental bioenergetic metabolism of sperm, the oxidative phosphorylation, glycolysis, and the pentose phosphate pathway presented significant changes under the treatment of seminal receptacle contents, indicating intensive regulation for sperm in the seminal receptacle. Additionally, the seminal receptacle contents also significantly increased the oxidation level of sperm, whereas the enhancement of abundance in superoxide dismutase, peroxiredoxin 1, and glutathione S-transferase after incubation with egg water significantly improved the resistance against oxidation. These results provided a new perspective for reproduction studies in crustaceans.
