Single-Course English 5 ECTS

Low Trophic Aquaculture

Overall Course Objectives

General course objectives:
To provide students with a fundamental knowledge about Lower Trophic Aquaculture (LTA), including culture technologies, environmental interactions, and the cultivation of different species of shellfish, macroalgae, microalgae, crustaceans, and gastropods. Students will become familiar with basic concepts in LTA and the biological and technical background for the cultivated species. The students will be introduced to different farmed species through different practical exercises and excursions to commercial production sites and companies. The students will learn the processes and requirements for controlled life cycles of different species in LTA starting from the hatchery and through to grow-out. Students will be able to identify low trophic species’ physiological parameters used for growth models and plan a production cycle. The course will familiarize the students with the management and technology used in hatcheries, hatchery processes, and aspects of biosecurity. The students will be able to cultivate different species in LTA through the application of appropriate husbandry techniques and technologies. Lastly, students will become familiar with the role of LTA in watershed nutrient cycles, coastal ecology, and the ecosystem services that LTA can provide from an environmental management perspective.

Learning Objectives

  • Provide an overview of the main produced species in LTA.
  • Explain the requirements for the different species life cycle.
  • Identify the different phases of low trophic species aquaculture: from juveniles to grow-out
  • List the biosecurity measures for LTA.
  • Conduct and plan production cycles of different species.
  • Organize logistic and monitoring program for managing LTA production.
  • Report on how to establish a new LTA business.
  • Demonstrate the role of LTA species in ecosystem services.
