• In marine aquaculture, the authorisation procedure is a complex procedure which on average can last 30 and 33 months on average in inland aquaculture.
• Lack of predictability and legal certainty. Predictability", understood as the consistent application of regulations and transparency in the decision-making process, is particularly critical for aquaculture activity with regard to the use of space, renewal of authorisations and the right to access water.
• Inefficiencies in the design of policies and strategies lead to difficulties in developing the activity, both in public and private actors.
• Limitations in knowledge of the best sites may compromise funding for the new projects and weaken the positioning of the activity in other management tools.
• Lack of legal and/or unclear procedures for the declaration of zones; low application of tools to reduce burdens and simplify procedures in the zones.
• Difficulties in maintaining traceability throughout the marketing chain.
• Low percentage of aquaculture producers associated to producer organisations.
• Difficulties for the correct positioning of aquaculture products in the markets.
• High economic impact due to animal diseases and insufficient knowledge on animal welfare.
• Lack of an integrated and global vision of environmental monitoring
• Complexity of the adaptation of the activity to the effects of climate change.
• Insufficient innovative potential of companies. Need for alignment between science-sector actions.
• Challenges in food and nutrition, animal health and welfare, genetics and physiology, diversification, engineering, management and aquaculture 4.0, environmental aspects, climate change, socio-economic aspects, quality, traceability and food safety.
• Lack of quality in the information produced due to mismatches between the information obtained and the real information needs.
• Low level of knowledge about the aquaculture sector among the general population. Need for more initiatives to communicate and promote aquaculture activity.
• Lack of confidence in the potential of aquaculture for local development and in the exploitation of synergies with other activities, which implies a loss of opportunities for diversification of income sources. 

• The need to develop strategies to implement European policies, as well as the incipient incorporation of aquaculture in priority strategies in other areas, represents an opportunity to design effective and realistic strategies.
• Marine Spatial Planning for aquaculture can serve as a tool to support sectoral planning, improve legal certainty and contribute to the sector's growth expectations and job creation in aquaculture.
• The new traceability systems represent a great opportunity to facilitate the processes for producers and to improve the transparency and visibility of the administration's actions.
• The high level of per capita consumption of aquatic products in Spain offers the opportunity to make progress in the diversification of supply and the enhancement of the value of national products.
• The existence of different types of companies can allow very different products to be placed on the market and help Spanish aquaculture to face the different challenges presented by the internationalisation of markets and emerging markets.
• The increase in demand for sustainable and local products, together with the increase in consumption of organic products, are also an opportunity for producers.
• The financial support of the FEMP-FEMPA is a valuable tool to be able to face all the challenges that lie ahead.
• Regulatory developments in animal health or veterinary medicines, as well as tools for the surveillance of antibiotic resistance, will contribute to improve the health governance of aquaculture.
• Improved water quality monitoring tools, in the framework of the new hydrological planning, will be very useful for the improvement of water quality for aquaculture.
• The creation of the National Reference Centre for Animal Welfare can be a useful tool to improve knowledge and coordination between administrations and with the sector on fish welfare.
• Some modifications or improvements in the regulatory framework applicable to aquaculture can generate new opportunities to improve the sustainability of the activity.
• The Second National Plan for Adaptation to Climate Change 2021-2030 will work specifically on the impacts and risks of climate change and the vulnerability of aquaculture activity, which will generate knowledge and facilitate access to the different actors.
• The EU Framework Programme for Research and Innovation, Horizon Europe, as well as the Spanish Strategy for Science, Technology and Innovation 2021-2027 offer an important opportunity to deepen research and innovation in aquaculture.
• National and regional administrations can use FEMPA funds to support investments in innovative solutions in the sector.
• European and national policies in the field of data collection aim at improving information exchange, simplification, data quality, transparency, and the use of statistics for policy design, implementation, monitoring and evaluation.
• The EU plans to launch a coordinated communication campaign on the EU model of sustainable aquaculture throughout the EU, which is an opportunity to raise awareness of aquaculture.
• The use of new technologies for the transmission of information (electronic delivery notes, QR codes) will play a key role in improving information at points of sale.
• Making the most of the opportunities offered by communication tools (social media, campaigns, influencers, recognised opinion leaders) will help to improve the image of aquaculture and consolidate product consumption.
• Increased consumer awareness enables local aquaculture products to compete on the basis of quality, proximity and product safety. The incorporation of aquaculture into the food culture will allow the consolidation of the activity as a tool for the conservation of uses and customs.
• The incorporation of aquaculture in the Participatory Local Development Strategies of the Fisheries and Rural Local Action Groups is an excellent opportunity to raise awareness of the possibilities of the activity and to promote initiatives at local level. Funding is available under the EMFAF and EAFRD.

The organisation and management of aquaculture is an exclusive competence of the Autonomous Communities, as laid down in their Statutes of Autonomy and in the Decrees on the Transfer of Competences, in accordance with Article 148 (1.11) of the Constitution. The Autonomous Communities have legislation for the management and regulation of aquaculture activity, which includes the requirements for the approval of establishments and aspects relating to the management, monitoring and control of the activity.

On the other hand, the State, through the Directorate General for Coasts of the Ministry for Ecological Transition and the Demographic Challenge (MITERD), exercises competence to authorise the occupation of the publicly owned maritime and terrestrial domain, except in some Autonomous Communities such as Catalonia and Andalusia

Ministry of Agriculture, Fisheries and Food (MAPA) through the General Secretariat for Fisheries (SGP), it is responsible for planning and executing policy on maritime fisheries in external waters and aquaculture, coordinating Community aquaculture policy and participation in international organisations. It is also responsible for planning, coordination and support for innovation in the sector, the planning of economic activity in the marketing and processing of products and relations with the competent international bodies in matters of foreign trade and fishing markets.
