Impacts of land use on water quality and the viability of bivalve shellfish mariculture in the UK: A case study and review for SW England
This paper examines how land use affects water quality and how this impacts the viability of shellfish mariculture (marine aquaculture) in the UK through a synthesis of the current literature, stakeholder workshops and
targeted engagement of cross-sector organisations across a case study in South West England. We examine the
importance of water quality as a constraint for shellfish mariculture in South West England and explore how
current and projected future land uses are likely to influence ongoing viability. Currently, faecal material from
agricultural runoff and municipal wastewater discharges is the main water quality issue affecting the viability of
shellfish mariculture. Most UK Shellfish Waters, including those in SW England (~90%), do not consistently meet
regulatory standards for faecal indicator organisms (FIOs) in shellfish, designed to ensure they are safe for direct
human consumption. Other pollutants currently impacting shellfish mariculture include persistent organic polïżœlutants and metals, suspended solids and excess nutrient inputs. Emerging pollutants with the potential to impact
on mariculture include a range of consumer- industrial- and agri- chemicals, including biocides, pesticides,
veterinary and human medicines. We evaluated possible changes in water quality conditions through deriving
and exploring a range of future scenarios, considering policies and trends in land use including regenerative and
intensive agriculture, renewable energy generation, afforestation, urban development and climate change. Our
findings highlight possible trade-offs and synergies between land and water-based food production systems,
applicable in SW England and across other regions of the UK and internationally, for helping to inform environmental policy development and implementation

Observation of Two New Excited Îb0 States Decaying to Îb0 K-Ï+
Two narrow resonant states are observed in the Îb0K-Ï+ mass spectrum using a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the LHCb experiment and corresponding to an integrated luminosity of 6 fb-1. The minimal quark content of the Îb0K-Ï+ system indicates that these are excited Îb0 baryons. The masses of the Îb(6327)0 and Îb(6333)0 states are m[Îb(6327)0]=6327.28-0.21+0.23±0.12±0.24 and m[Îb(6333)0]=6332.69-0.18+0.17±0.03±0.22 MeV, respectively, with a mass splitting of Îm=5.41-0.27+0.26±0.12 MeV, where the uncertainties are statistical, systematic, and due to the Îb0 mass measurement. The measured natural widths of these states are consistent with zero, with upper limits of Î[Îb(6327)0]<2.20(2.56) and Î[Îb(6333)0]<1.60(1.92) MeV at a 90% (95%) credibility level. The significance of the two-peak hypothesis is larger than nine (five) Gaussian standard deviations compared to the no-peak (one-peak) hypothesis. The masses, widths, and resonant structure of the new states are in good agreement with the expectations for a doublet of 1D Îb0 resonances
