Накратко на български

Микробите, живеещи в стридите, се изследват, за да се разбере как влияят върху здравето им при промяна на климата и болести. Това помага за устойчивото производство на миди и възстановяването на природните им местообитания.

The role of Microbes in Aquaculture: understanding the functional role of oyster microbiomes in response to changing climates and diseases

Owing to the ecological and economic importance of bivalves, understanding their functional role in habitats, and their susceptibility to climate change and diseases is of great importance. In Europe, aquaculture produces 1.3 million tonnes of seafood, with molluscan aquaculture production of oysters, clams and mussels contributing ~47%. Bivalve production has a low environmental footprint and plays a substantial role in economic decoupling by achieving economic growth while preserving a healthy environment by recycling nutrients (removal of nitrogen and carbon), stabilising sediments, and enhancing biodiversity. In addition to the production of bivalves for human consumption, bivalve stock production is vital for the restoration of lost native oyster habitats. Environmental stressors and emerging pathogens represent serious limitations to the sustainable production of bivalves and their role in ecological functioning of ecosystems. A changing climate and marine environment challenges bivalve physiology leading to increased susceptibility to infection and the diversion energy from reproduction and growth. These challenges limit sustainable biomass production as well as the socioeconomic and ecological benefits that bivalve culture provides to near shore coastal communities. While significant research has been conducted on the larger scale regarding production and the ecological role of oysters, as well as whole organism responses to changing climates and pathogens, little research has been conducted on the role of oyster-associated microbes in relation to oyster health. Improvements in understanding host-microbe interactions and the roles of microbes in host functioning have increased the recognition of microbial associations in ecology. Research in humans and other higher organisms has shown that these small scale communities play important roles in disease resistance and individual performance (longevity and reproductive ability/fecundity). Therefore, in the case of oysters, the functional role of microbiomes in resistance to climate change and disease susceptibility may be a crucial factor for production and continued persistence that has not been explored in-depth. The overarching aim of the MicroAqua project is to address critical knowledge gaps in our understanding of how oyster microbiomes contribute to oyster functioning, health, and resistance to pathogens under climate change. Through the implementation of multidisciplinary work packages, this project will (1) gain insights into spatio-temporal and tissue specific microbiota of oysters, (2) assess how various climate change scenarios impact oyster microbiomes and oyster health, (3) investigate the impact of emerging pathogens on oyster microbiomes and health, and (4) assess the potential of marine bivalve-derived bacteria as probiotics to reduce mortality in oysters. This project intended to use a combination of next-generation sequencing technologies to provide a greater understanding of the functional role of oyster microbiomes, and the potential importance of host-microbe interactions for these important aquaculture species.

Цел на проекта

Bivalves are ecologically and economically important in Europe. Oysters in particular provide ecological benefits through habitat provision, economic benefits through aquaculture production, and societal benefits through cultural associations. Although of high importance, oyster production is threatened by changing climates and disease proliferation which cause mass mortality events. Recent advancements show that microbiomes, the microbial community within a host organism, play a significant role in the functioning of the host and their resistance to adverse conditions. This project will incorporate knowledge from the fields of global change ecology, shellfish health and diseases, and microbiology to increase the understanding of the role of the oyster microbiome in resistance to threats posed by climate change and disease proliferation, as well as the overall performance of oysters in the environment. By combining field and laboratory investigations of how the physical environment affects microbial functioning within oysters produced by both wild and hatchery based stocks, and subsequently their susceptibility to pathogens, this project will provide a holistic, in-depth understanding of the contribution of such microscopic organisms to these valuable bivalve species. Results will be beneficial to the scientific community, aquaculture stakeholders, policy makers, and coastal societies alike. Project outcomes will move forward the integration of microbiology into the success of aquaculture to increase production, sustainability, and blue growth.
