“…Moreover, cultured ark shells, especially those cultured in outdoor ponds in China, are vulnerable to high temperature and their growth and survival are often threatened severely by continuous or extreme high temperature in summers (Lin J. L. et al, 2020;Ning et al, 2021). The seawater temperature of outdoor shallow ponds in Northern China can reach as high as 33.5 • C in summer (Ning et al, 2015), thus pond cultured ark shells are often exposed to acute or chronic high temperature stress during this period. Therefore, in this study, we investigated the effects of acute or chronic thermal stress on apoptosis, physiological performance, and gene expression of ark shells, which would help to understand the thermal tolerance and contribute to selection of heat-resistant strains in ark shells.…”

Ark shells (Scapharca subcrenata) grown on the tidal flats are often exposed to high temperature stresses in summer. In order to better understand their adaption to extreme or natural high temperature, we first determined the 96-h upper lethal temperature of ark shell and then investigated their physiological and transcriptional responses to acute or chronic thermal stress at the 96-h upper median lethal temperature (32°C). A significantly higher cumulative mortality (52% in 96 h) was observed in the acute heating treatment (AHT) group than that (22% in 7 days) in the chronic heating treatment (CHT) group. The apoptosis and necrosis rates of hemocytes were increased significantly in a time-dependent manner under both thermal stress strategies. Activities of antioxidant enzymes [superoxide dismutase (SOD) and catalase (CAT)] increased dramatically in a short time followed by a quick decline and reached to a lower level within 12 h in the AHT group, but maintain relatively high levels over a long period in the CHT group. The contents of malondialdehyde (MDA) were increased significantly firstly and restored to the original later in both acute and chronic thermal stress. Moreover, expression of the genes related to heat shock proteins (HSPs; HSP90, HSP70, HSP20, and sHSP), apoptosis [TNF receptor-associated factor 6 (TRAF6), glucose regulated protein 78 kD (GRP78), and caspase-3 (Casp-3)] and antioxidant responses [glutathione S-transferase (GST) and multidrug resistance protein (MRP)] could be induced and up-regulated significantly by thermal stress, however, expression of regucalcin (RGN), metallothionein (MT), and peroxiredoxin (PRX) was down-regulated dramatically under the two heating treatments. These results suggested that anti-apoptotic system, antioxidant defense system and HSPs could play important roles in thermal tolerance of ark shells, and the heat-resistant ark shell strains could be selected continuously by properly chronic thermal stress.

“…Temperature and salinity are considered as the main physiological factors affecting aquatic animals in ecological systems (Kinne, , ). Previous studies have demonstrated that temperature (Dong, Dong, Tian, Wang, & Zhang, ; Dong, Ji, Meng, Dong, & Sun, ; Kuhnhold et al, ; Ning et al, ; Sun et al, ) and salinity (Bai et al, ; Geng et al, ; Meng, Dong, Dong, Yu, & Zhou, ) are closely related to growth, behaviour, survival and physiological metabolism of sea cucumber A . japonicus .…”

Quality evaluation of indoor‐ and outdoor‐cultured sea cucumber ( Apostichopus japonicus ) seedlings: Insight from survival and immune performance in response to combined stress of hyperthermia and hyposalinity

et al. 2019

The mass mortalities of sea cucumber Apostichpous japonicus have prevailed in northern China, mainly attributing to the emergence of extreme environmental conditions, that is hyperthermia and hyposalinity. The high-quality sea cucumber seedlings appear to possess more robust resistance to adverse conditions. There are usually indoor-and outdoor-cultured seedlings in industrial production of sea cucumbers.Although the outdoor-cultured sea cucumbers are practically considered to be more strong and robust, the effective evaluation approach to distinguish these seedlings has been scarce. The current study compared survival and immune performances of indoor-and outdoor-cultured A. japonicus under combined exogenous stressors, that is hyperthermia and hyposalinity. Results based on secondary stress induction revealed that the activities of immune enzymes and levels of catecholamines in body wall of outdoor-cultured seedlings were prominently higher than those of indoor-cultured seedlings recovered for 0-72 hr following sublethal stress (30°C and 25 psu of salinity). The opposite case occurred on immune enzymes in coelomic fluid of the two sources of seedlings except for myeloperoxidase. Importantly, the outdoor-cultured seedlings, which were recovered for 72 hr after sublethal stress, exhibited a 93% of cumulative survival rate following 7 days of recovery after lethal stress (33°C and 20 psu of salinity), 27% higher than the indoor-cultured seedlings. Collectively, the outdoor-cultured A. japonicus seedlings showed more superior quality than the hatchery-produced seedlings in terms of survival and immune performance. These findings provide practically useful information towards quality distinction of the indoor-and outdoor-cultured sea cucumbers, which could benefit the aquaculture industry to obtain high-quality seedlings.
