“…Gradient cooling domestication can reduce temperature stresses of PY distributed in cold chain so that method has reduced the mortality and prolonged the survival time. However, but in this experiment, PY has low tolerance of exposed air stress, so their survival time is shorter than that of clam (Anacleto, Maulvault, Barrento, et al., ; Anacleto, Maulvault, Chaguri, et al., ), Mytilus edulis (Barrento, & Powell, 2016), and other bivalves (Phuvasate et al., ).…”

“…During the depuration process, the number of bacteria or other pathogenic bacteria within the scallop was reduced, so the scallop thus became more adaptable to the environmental stress. Therefore, proper depuration and temporary keeping will not reduce the survival rate of shellfish during the transportation process (Anacleto, Maulvault, Barrento, et al, 2013;Anacleto, Maulvault, Chaguri, et al, 2013).…”

“…In the supply chain, scallop is subjected to several stressors during capture, depuration, storage, and transportation, including prolonged periods of air exposure and temperature fluctuation. The stressors strongly decrease the bivalves’ quality, cause some changes in the bivalves’ metabolism, and contribute to severe economic losses along the trade chain (Anacleto, Maulvault, Barrento, et al., ; Anacleto, Maulvault, Chaguri, et al., ).…”

“…During fishery transportation, the live shellfish should be stored in favorable living conditions for longer survival time. Typically, the survival rate declined over time affected by three steps, such as depuration, temporary keeping, and waterless-low-temp transportation (Anacleto, Maulvault, Barrento, et al, 2013;Anacleto, Maulvault, Chaguri, et al, 2013).…”

The supply chain of shellfish is complex, with animals being subjected to several stressors during the depuration, temporary keeping, and waterless‐low‐temp transportation processing. In this paper, the recycled water system for depuration and temporary keeping was used to realize both depuration and temporary keeping of Patinopecten yessoensis. The samples were divided into three groups based on three different pre‐process involved: samples in group 1 were depurated for 48 hr straight, whereas those in group 2 were first depured for 24 hr and then cooled for 24 hr; samples in group 3 was directly kept in a polyethylene insulation box. Then group 1 and group 2 were transported in a 3L polyethylene insulation box with ice packs (250 ml) to study the quality of transport based on the different pre‐process. As a result, in group 1 (depuration for 48 hr), the first death occurred after 56 hr, and all shellfishes died after 102 hr with total bacterial density of 2,630 CFU/ml. In group 2 (depuration for 24 hr and temporary keeping for 24 hr), the first death occurred after 104 hr and the total number of bacteria was increasing steadily within 0–104 hr. After 120 hr, all shellfishes died with total bacterial density of 1,090 CFU/ml. In group 3 (directly transport), all shellfishes died in 64 hr. The total number of bacteria in groups 1 and 2 declined significantly in the depuration process. The bacteria number (p < 0.05) in group 3 was significantly different from that in groups 1 and 2. The crude protein, crude fat, and glycogen of all groups declined. However, compared to groups 1 and 3, the consumption of glycogen in group 2 (p < 0.05) was delayed by the gradual cooling procedure. Those results prove that the depuration and temporary keeping procedures can improve the sterilization of the bacteria. The survival rate is less sensitive to the temperature change. The results provide satisfactory references for the P. yessoensis’ quality studies with depuration, temporary keeping, and waterless‐low‐temp transportation technologies.

The current study reports metals and arsenic (As) concentrations present in sediments and in the native clam Venerupis corrugata, collected in the Ria de Aveiro, one of the most important aquatic systems of the Portuguese coast with high biodiversity and socio-economic value. Because of its ecological importance in its habitat, and being one of the most exploited bivalve mollusks in Portugal, several biochemical biomarkers were evaluated in order to illustrate the species status when under environmental conditions. The concentration of metals and As in the sediments showed an increase of contamination among areas (areas A-E). The results proved higher bioaccumulation in organisms from the area less contaminated (area A, BAF > 1). The concentration of metals and As was predominant (63.4%) in the insoluble fraction of clams. The biochemical evaluation evidenced an increase of oxidative stress in organisms from the most (D and E) and the less (area A) contaminated areas, demonstrated by higher LPO levels, CAT, and GSHt activities at these areas and the increase of methalotionines (MTs) along the concentration gradient. This suggests a preventive mechanism in order to protect cells against pollutants (metals and As).
