“…The physiological response to exposure was explored through the hemolymph of the scallop, which is the invertebrate analog to vertebrate blood and performs many of the same functions, including gas exchange, nutrient and waste transport, osmoregulation, and immune function (45). Although these hemolymph parameters are useful for interpreting health, care must be taken in comparisons over time, as bivalve hemolymph tends to show considerable variation in hemolymph parameters in response to biotic (reproductive cycle, nutritional condition) and abiotic (temperature, food availability) factors (30,(49)(50)(51). This variability is particularly relevant to the 2015 experiment in this study, which was conducted in the summer, whereas the 2013 and 2014 experiments were conducted in the winter.…”

Seismic surveys map the seabed using intense, low-frequency sound signals that penetrate kilometers into the Earth's crust. Little is known regarding how invertebrates, including economically and ecologically important bivalves, are affected by exposure to seismic signals. In a series of field-based experiments, we investigate the impact of exposure to seismic surveys on scallops, using measurements of physiological and behavioral parameters to determine whether exposure may cause mass mortality or result in other sublethal effects. Exposure to seismic signals was found to significantly increase mortality, particularly over a chronic (months postexposure) time scale, though not beyond naturally occurring rates of mortality. Exposure did not elicit energetically expensive behaviors, but scallops showed significant changes in behavioral patterns during exposure, through a reduction in classic behaviors and demonstration of a nonclassic "flinch" response to air gun signals. Furthermore, scallops showed persistent alterations in recessing reflex behavior following exposure, with the rate of recessing increasing with repeated exposure. Hemolymph (blood analog) physiology showed a compromised capacity for homeostasis and potential immunodeficiency, as a range of hemolymph biochemistry parameters were altered and the density of circulating hemocytes (blood cell analog) was significantly reduced, with effects observed over acute (hours to days) and chronic (months) scales. The size of the air gun had no effect, but repeated exposure intensified responses. We postulate that the observed impacts resulted from high seabed ground accelerations driven by the air gun signal. Given the scope of physiological disruption, we conclude that seismic exposure can harm scallops.

“…Immune-related enzymes, as the key components of innate immune system in marine invertebrates, were commonly used as the parameters for evaluation of organism immunocompetence (Wang, Yang, Gabr & Gao 2008;Lin, Xing, Jiang, Tang & Zhan 2011). Studies indicated that the immune parameters of marine invertebrates usually showed seasonal variations during a year cycle for the effects of environmental factors (Tokutake et al 1992;Luna-Gonz alez et al 2008;Lin et al 2012). A. japonicus is an economic species of marine invertebrates, and its production mainly depends on pond culture (Chang, Sui & Li 2006).…”

“…The immune-related enzymes play crucial roles in the immune response of echinoderms for their direct involvement in the extermination of pathogens or clearance of harmful substances. For example, in the scallop Chlamys farreri, the activities of peroxidase and PO showed high level in spring and early summer but low level in summer and early autumn, while that of SOD had small values in spring but high values in summer (Lin, Zhou, Lai, Yao, Li & Xing 2012). Recent studies showed that the activities of immune-related enzymes in echinoderms were very sensitive to some environmental factors like temperature, salinity, pH and dissolved oxygen (DO) Zheng, Li, Rong, Liao, Chen, Zhang, Wang, Wang & Zou 2014), suggesting the immunocompetence of echinoderms might have a close relationship with the seasonal change.…”

“…Actually, the seasonal variations of immune parameters have been proved in several marine invertebrates. For example, in the scallop Chlamys farreri , the activities of peroxidase and PO showed high level in spring and early summer but low level in summer and early autumn, while that of SOD had small values in spring but high values in summer (Lin, Zhou, Lai, Yao, Li & Xing ). In addition, the LYZ activity of clam Tapes philippinarum presented low level in spring but high level in winter (Tokutake, Mochizuki & Matsumiya ), while that of oyster Crassostrea gigas had small values in winter but high values in summer (Luna‐González, Romero‐Geraldo, Campa‐Córdova, Orduña‐Rojas, Valles‐Jiménez & Ruíz‐Verdugo ).…”

Seasonal variations of immune parameters in the coelomic fluid of sea cucumber Apostichopus japonicus cultured in pond

In order to understand the effects of seasonal change on the immunity of sea cucumber Apostichopus japonicus cultured in pond, A. japonicus with body weight of 12.2 AE 4.5 g (sample A) and 32.6 AE 7.1 g (sample B), respectively, were collected monthly and randomly from a typical pond during a year cycle and employed for the evaluation of immunocompetence. Simultaneously, the environmental factors in the pond including water temperature, pH, salinity and dissolved oxygen (DO) were measured using a handheld multiparameter meter. The activities of acid phosphatase (ACP), alkaline phosphatase (ALP), lysozyme (LYZ), phenoloxidase (PO), superoxide dismutase (SOD), catalase (CAT) and myeloperoxidase (MPO) in the coelomic fluid were selected for the evaluation of A. japonicus immunocompetence and determined using biochemical methods. The results showed that in both samples, the activities of all determined enzymes had small values in winter and early spring, and LYZ, CAT and MPO activities also presented small values in summer, suggesting that pond-cultured A. japonicus underwent immunosuppression twice during a year cycle, and the immunosuppression occurred in winter and early spring was more severe than that occurred in summer. In addition, most of the determined enzymes showed different variations between the two samples, and had significantly negative correlation with protein concentration, which was significantly and negatively correlated with water temperature, revealing that body weight and water temperature might have crucial effects on the immunity of A. japonicus cultured in pond.
