WP4 - Aquaculture Health: Recurrent and Emerging Diseases (AQUAHEALTH)

The WP4 (AQUAHEALTH) is focused on the health in aquaculture addressing both recurrent and emerging diseases. WP4 aims to understand the pathogens and associated pathologies affecting the sector, as well as detect and control the main diseases. It is structured around seven objectives: 7) Identify and characterize emerging pathologies, and develop and improve methods of diagnosis and detection; 2) Study the life cycles, the vectors and the impact of climate change on the etiological agents and their interaction with their hosts; 3) Design new vaccines against the most relevant pathogens and study the administration routes; 4) Develop new alternative methods, sustainable treatment and control, both therapeutic and prophylactic; 5) Create a Mediterranean Research Network on Aquaculture Health (REMEDISA) that integrates the knowledge, experiences and capabilities of the R&D&I groups of the Valencian Community; 6) Disseminate the project, transfer the scientific-technical tools generated for the sector and raise awareness in society about sustainable development; 7) Train competent personnel in animal health and welfare

Objectives

Objective 4.1

Identify and characterize new emerging pathologies, and develop and improve methods for diagnosing and detecting pathogens in aquaculture.

  • Action 2.2: Studies of the physiology, pathology, and reproduction of cultivable fish to improve knowledge of processes affecting development, growth, quality of spawn and offspring, and animal health and welfare, as well as the rhythmic control of physiological processes and their modulation by environmental factors in model and aquaculture species.
  • Action 2.9: Improving fish farming systems by i) developing more efficient and sustainable feeds, especially during the larval stage and juvenile production, ii) optimizing environmental factors and chronobiological control, iii) optimizing production (machine learning) through genetic improvement, animal welfare, and the prevention and control of pathologies with diagnostic tools, treatments, and novel technologies.
  • Action 2.6: Promoting the development of non-conventional farming systems for aquatic organisms. Promoting research and development of non-conventional farming systems for fish, mollusks and other taxonomic groups: IMTA (offshore and onshore), recirculating water systems (RAS) and aquaponics-BIOFLOC.
  • Homework 4.1.5: Alternative pathogen detection

Objective 4.2

To study the life cycles of fish pathogens, their vectors, and the impact of climate change on these pathogens and their interactions with their hosts.

  • Action 2.2: Studies of the physiology, pathology, and reproduction of cultivable fish to improve knowledge of processes affecting development, growth, quality of spawn and offspring, and animal health and welfare, as well as the rhythmic control of physiological processes and their modulation by environmental factors in model and aquaculture species.
  • Action 2.11: Improving knowledge about crop welfare and developing systems that allow for continuous and reliable monitoring of: i) new welfare indicators under normal farming conditions and during the slaughter process (where applicable) and ii) developing strategies to improve feed intake and utilization, growth, reproduction and health status (susceptibility to disease) of farmed specimens.

Objective 4.3

Design new vaccines against the most relevant pathogens and study the best administration routes.

  • Action 2.15: Establishment of biosanitary measures and design of protocols and other specific control measures (vaccines, prebiotics, probiotics, alternative treatments, etc.) to mitigate the effects of climate change and the intensification of fish farming on epizootics due to recurrent and emerging pathogens.
  • Homework 4.3.1: Development of a DNA vaccine against Enteromyxum leei.
  • Homework 4.3.2: Design of vaccines for zoonotic vibrios.
    • ResponsibleUV1

Objective 4.4

Develop new, alternative, eco-sustainable methods for treating and controlling pathogens in aquaculture, both therapeutic and prophylactic.

  • Action 2.15: Establishment of biosanitary measures and design of protocols and other specific control measures (vaccines, prebiotics, probiotics, alternative treatments, etc.) to mitigate the effects of climate change and the intensification of fish farming on epizootics due to recurrent and emerging pathogens.
  • Homework 4.4.3: Evaluation of the microcidal potential of electrolyzed water.

Objective 4.5

Create a Mediterranean Research Network on Aquaculture Health (REMEDISA) that integrates knowledge of large groups of infectious agents (viruses, bacteria, and parasites) and the diverse experience and capabilities of R&D&I groups in the Valencian Community.

  • Action 2.2: Studies of the physiology, pathology, and reproduction of cultivable fish to improve knowledge of processes affecting development, growth, quality of spawn and offspring, and animal health and welfare, as well as the rhythmic control of physiological processes and their modulation by environmental factors in model and aquaculture species.
  • Action 2.20: Improving the perception and social acceptance of aquacultureImproving environmental awareness, transparency, and the perception of aquaculture by all sectors of society to facilitate the introduction and consolidation of safe, high-quality aquaculture with a high technological component based on sustainability principles.

Objective 4.6

Disseminate the project's results, transfer the scientific and technical tools generated to the sector, and raise awareness about the sustainable development of Mediterranean aquaculture.

  • Action 3.12: Dissemination of knowledge and education about the marine environment to society at large (children, consumers, professionals from different fields, etc.) to improve perceptions of blue economy activities (artisanal fishing, aquaculture, etc.).
  • Homework 4.6.1: Dissemination and transfer of scientific and technical knowledge and tools

Objective 4.7

To train competent personnel in animal health and welfare in aquaculture.

  • Action 3.12: Dissemination of knowledge and education about the marine environment to society at large (children, consumers, professionals from different fields, etc.) to improve perceptions of blue economy activities (artisanal fishing, aquaculture, etc.).
  • Homework 4.7.1: Training of future health professionals in aquaculture through workshops, specialization courses/master's degrees in companies, universities and research centers
  • Homework 4.7.2: Promoting the shared use of research resources and infrastructure
