Poor growth greatly reduces the production efficiency of small sea cucumbers Apostichopus japonicus in summer. The present study found that crawling frequency and tentacle activity frequency of sea cucumbers (~1 g of wet body weight) were significantly lower at 25°C than those at 16°C. These...

Circular RNAs (circRNAs) are a class of widespread and diverse covalently closed circular endogenous RNAs that play pivotal roles in mediating immune regulation in mammals. However, the function and regulatory mechanisms of circRNAs in lower invertebrates are still far unidentified. In this study,...

Reproduction of the sea cucumber Apostichopus japonicus is critical for aquaculture production. Gonadal development is the basis of reproduction, and lipids, which are among the main nutrients required for gonadal development, directly affect reproduction. We investigated whether gonadal and...

Since the early 1980's there has been an increase in sea cucumber harvest and trade, mainly due to Asiatic market pressure. In the Indo-Pacific regions, the collapse of various stocks of these echinoderms has already occurred due to overfishing. In Europe, sea cucumber exportation depends...

As one of the most economically significant sea cucumber species, Holothuria scabra are naturally distributed in the Indo-West Pacific region and are widely cultural in Southeast Asia. The appearances of female and male H. scabra have no obvious phenotypic dimorphism. Thus, identification of...

Sandfish (Holothuria scabra) is a very commercial species compared to other types of sea cucumber; hence, stock in nature decreases as the exploitation increases. It is, thus, designated by IUCN as an endangered species, consequently, the species requires cultivation activities. However, currently, ...

Sedimented particulate organic matter is an important sea cucumber feed source. To understand the effect of different management modes on the proportion of exogenous sedimented particulate organic matter in sea cucumber ponds, a natural tidal pond, a microporous aeration pond, and a water quality...

To reveal the environmental regulation mechanism and aquaculture of tropical sea cucumber, and provide scientific basis for its artificial breeding, we studied the seasonal variations of physiological and biochemical conditions of Holothuria edulis, monitored the changes of the digestive tract...

The functional characteristics of neuropeptides in marine invertebrates have attracted significant attention recently although functional studies of luqin-type neuropeptides are still very limited, especially in deuterostomes. The sea cucumber, Apostichopus japonicus, is a representative species of ...

A 60-day feeding trial was conducted to investigate the effects of dietary folic acid on the growth performance, growth gene expression, body wall folate content, and digestive, immune and antioxidant enzyme activity of juvenile sea cucumber (initial body weight: 0.60 ± 0.01 g). Five diets were...
