Following the 2007 Infectious Salmon Anaemia (ISA) crises, Aquaculture Management Areas (AMAs) were introduced. Also known as barrios or neighborhoods, AMAs are managed by the National Service for Fisheries and Aquaculture. AMAs consist of groups of licence holders who are required to coordinate management practices and biosecurity measures. Emergency disease zones, known as Macro Zones, have also been introduced. These focus on emergency fish health management and disease containment, and only become active in the case of disease outbreak.
The selection of appropriate sites and the granting of seabed leases for salmon farming are guided (in part) by locational guidelines produced by Marine Scotland Science. These estimate nutrient enhancement and benthic impact in sea lochs and classify marine areas according to their suitability for farming. Disease Management Areas (DMAs), which are overseen by the Fish Health Inspectorate, have been introduced to guide siting and protect the industry from outbreaks of ISA by guiding farm siting and requiring farmers to coordinate production practices.
The Scottish Salmon Producer Organization have produced a mandatory Code of Good Practice (CoGP) which requires farms to coordinate production and the control of sea lice (Lepeophtheirus salmonis) under Farm Management Areas (FMAs). FMAs have been incorporated into the Aquaculture and Fisheries (Scotland) Act 2013 and are now mandatory.
Under the leadership of the Hainan Tilapia Sustainability Alliance and the support of the NGO, China Blue, the tilapia industry in Hainan is adopting a zonal management approach through the development and enforcement of a CoGP. The CoGP is now in its second edition, and outlines best management practices at the farm- and zonal-level. Current HTSA member compliance with the first edition of the CoGP is 100%, while the second edition has been applied to around 35 pilot farms. The HTSA also plans to introduce the CoGP to non-HTSA tilapia farms in Hainan as a voluntary standard.
In 2011, the HTSA also established an Aquaculture Improvement Project (AIP) in collaboration with SFP, and publishes quarterly AIP progress reports.
