Ocean-based industries like shipping, aquaculture, and wind energy are growing at an unprecedented rate resulting in challenges related to siting and environmental management. As marine aquaculture and other ocean-based industries continue to expand, robust marine spatial planning analyses that reconcile existing ocean uses and integrate pertinent environmental and planning data are critical for identifying compatible locations. In this study, a series of geospatial analyses were used for aquaculture siting within and around a heavily trafficked and highly utilized maritime port in the San Diego Bay area of California, USA. Using a centralized geodatabase representing key aquaculture planning spatial datasets, recommendations for specific areas for aquaculture were developed based on appropriate environmental conditions for candidate shellfish and algae aquaculture species culture systems. Areas that were known constraints were first identified to determine potentially usable areas for shellfish and macroalgae (i.e., seaweed) aquaculture using an exclusion analysis, a type of multi-criteria decision analysis, to eliminate all areas without compatibility. Within the remaining usable area, we further considered shellfish and macroalgae culture system-specific factors within a 'culture systems analysis' to determine where different culture systems have potential for success. This analysis provides a foundation of coastal intelligence for guiding the aquaculture industry and natural resource managers towards appropriate siting decisions. This study can serve as a replicable example of aquaculture spatial planning approaches for siting sustainable aquaculture and other blue economy industries.

China-based fish-farming ship Conson No. 1 has become the first large yellow croaker (Larimichthys croceus) farm to achieve the Aquaculture Stewardship Council (ASC) certification in December 2022. It is the world's first full-scale "smart farming ship" which can produce 3,700 tonnes of large yellow croaker annually. Local high-end retail company Ole has begun discussions to promote and source ASC certified large yellow croaker for consumers in China.

A healthy marine environment is integral to numerous New Zealand economic, social, and cultural values, including fisheries, aquaculture, tourism, and recreational and customary activities. The introduction and spread of marine non-indigenous species (NIS) via the vessel biofouling pathway may put these values at risk. Over the past two decades, the Ministry for Primary Industries (MPI) has been proactive in commissioning research focused on the risks associated with vessel biofouling, identification of potential risk vessels, and risk management options. In 2010, MPI consulted on options to manage the biofouling risks on all vessels entering New Zealand waters. In 2014, New Zealand became the first country to introduce mandatory biofouling requirements. Between 2014 and 2018, MPI focused on communicating the requirements to support stakeholder awareness, readiness, and uptake. In parallel, MPI commissioned further research to investigate proactive and reactive approaches to biofouling management. Research outcomes were summarized and technical advice provided to inform stakeholders of what constitutes best biofouling management practices. This review summarizes MPI's research and technical advice on the risks associated with vessel biofouling and its management, and the procedures followed to produce New Zealand's biofouling regulations. The development of these regulations is also contextualized in terms of New Zealand's marine biosecurity system. The transparent and evidence-based approach followed by MPI provides a blueprint for establishing biofouling regulations. Because these regulations are aligned with the International Maritime Organization guidelines, there is the potential to develop consistent global and domestic practices for managing marine NIS introduction and spread.
