“…Adaptive strategies to high suspended solids may be different between species and populations due to their adaptive capabilities and environmental histories. Intra-and inter-specific variations in responses to high suspended solids and sestons have been reported in previous studies [13,14]. Those variations may be associated with several intrinsic and extrinsic factors, for examples, concentrations and characteristics of suspended solids, body sizes of animals, filtration rates, and pseudofaeces production [15].…”

“…Differences in maintaining the filtration rates over the exposure time could be due to the degree of gill damages and the sediment rejection activity. Moreover, maintaining scope for growth, and food availability could help filter-feeding bivalves to cope with prolonged exposure to high suspended solids [12][13][14]. Further studies on gill microanatomy and microstructure associated with the body size are necessary for more in-depth understanding of how the mussel responding to various SP concentrations over different exposure times.…”

High suspended loading is one of the environmental stressors which could affect survival rates and feeding activities of marine bivalves especially the coastal species. Therefore, this study aimed to examine the effects of suspended particles (SP) on filtration rates of the green-lipped mussel Perna viridis, which is a commercial bivalve species in Thai coastal waters. The large and small mussels were subjected to 250 mg and 500 mg of SP/l, and a control treatment (0 mg of SP/l) in the experimental laboratory. Filtration rates of the mussels were measured at day 0, day 15, and day 20 after the exposure to SP. The results showed that filtration rates of two class-sizes of the mussels significantly decreased after the exposure to SP for 15 and 20 days. Before the exposure to SP (day 0), the large mussels had significantly greater filtration rates than the smaller individuals, indicating the size-dependent effects. Filtration rates of the mussels decreased with increasing concentrations of SP. Gill abnormalities, e.g., loss of cilia on the gill lamella, were detected in the selected mussels at 500 mg of SP/l. The small mussels exhibited less capability in maintaining filtration rates compared with the larger mussels under high SP concentration. Moreover, changes in filtration rates over the exposure time were also discussed based in our study. Overall, the results can reflect deleterious effects of high SP on the mussels, particularly in filter-feeding activities. These findings could raise environmental concerns over high SP that could damage cultured mussels and coastal ecosystems.

“…This indicates that the dietary competition between C. gigas and M. galloprovincialis is not balanced. Although both C. gigas and M. galloprovincialis preferentially selected larger particles (>5 μm) in their diet, they did not necessarily need to compete, because M. galloprovincialis can also utilise smaller particles (<2 μm), which are not retained by C. gigas [ 48 ]. In fact, the invasion of C. gigas did not negatively affect local populations of the mussels M. edulis in Limfjord, Denmark, even though C. gigas were considered to have a competitive advantage owing to their higher filtration rate [ 49 ].…”

The Negative Relationship between Fouling Organisms and the Content of Eicosapentaenoic Acid and Docosahexaenoic Acid in Cultivated Pacific Oysters, Crassostrea gigas

Bivalves serve as an important aquaculture product, as they are the source of essential fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in our diet. However, their cultivation in the wild can be affected by fouling organisms that, in turn, affect their EPA and DHA content. The effects of fouling organisms on the EPA and DHA contents of cultivated bivalves have not been well documented. We examined the effects of fouling organisms on the EPA and DHA contents and condition index of cultured oysters, Crassostrea gigas, in an aquaculture system. We sampled two-year-old oysters from five sites in Shizugawa Bay, Japan, in August 2014. Most of the fouling organisms were sponges, macroalgae, and Mytilus galloprovincialis. A significant negative relationship existed between the DHA content in C. gigas and the presence of sponges and macroalgae. A lower C. gigas EPA content corresponded to a higher M. galloprovincialis fouling mass and a lower C. gigas condition index. This can be explained by dietary competition between C. gigas and M. galloprovincialis for diatoms, which were the main producer of EPA in our study sites. Our findings indicate that fouling organisms likely reduce the EPA and DHA content in cultivated oysters. Therefore, our results suggest that the current efforts to remove fouling organisms from oyster clusters is an effective strategy to enhance the content of EPA and DHA in oysters.

“…Buss et al (2019b) found higher B. exitiosa infection intensities were associated with lower meat:shell ratios for harvest size 20‐ to 22‐month‐old O. angasi in winter. Meat:shell ratio is driven by complex oceanographic and climatic factors that vary seasonally between sites (Grangeré, Ménesguen, Lefebvre, Bacher, & Pouvreau, ; Rahman, Henderson, Miller‐Ezzy, Li, & Qin, 2020). Oyster populations undergoing mortality caused by Bonamia spp.…”

Bonamia spp. cause epizootics in oysters worldwide. In southern Australia, Bonamia exitiosa Hine, Cochennac and Berthe, 2001 threatens aquaculture of Ostrea angasi Sowerby, 1871. Bonamia spp. infections can display strong seasonality, but seasonal dynamics of B. exitiosa–O. angasi are unknown. Ostrea angasi naïve to B. exitiosa infection were stocked onto farms in three growing regions, and B. exitiosa was monitored seasonally for one year. Environmental parameters we measured did not correlate with B. exitiosa prevalence or infection intensities. Extreme temperatures suggest O. angasi culture systems need development. Bonamia exitiosa prevalence increased over time. After three months, O. angasi had B. exitiosa prevalence of 0.08–0.4, and after one year, the prevalence was 0.57–0.88. At some sites, O. angasi had >0.5 B. exitiosa prevalence in >6 months, but at other sites, >9 months passed before prevalence was >0.5. Bonamia exitiosa infection intensities were low with no seasonal pattern but were affected by the interaction of site, season and oyster meat:shell ratio. Understanding infection and initiating a breeding programme for resistance would provide benefits for O. angasi industry expansion.
