Aquaculture Systems

Course Code: AQU 702

Course Title: Aquaculture Systems

Credit Hours: 3 (3+0)

Rationale:

Various aquaculture practices are evolved in various parts of the world and are practiced and functioning in different levels – local, national, regional and global. Understanding aquaculture systems in holistic perspective and its interrelations and trends are the basic requirements before going to the different specific fields of aquaculture.

This course overview the various aquaculture practices, their principles and its impact that are currently practiced in different levels in the national and also in international.

Learning Outcomes:

  1. Demonstrate knowledge of the different types of aquaculture practiced, and its impacts, at local, national and international levels
  2. Discuss factors, and their interaction, affecting the development and status of aquaculture.
  3. Design a resource based sustainable aquaculture system in a given situation.
  4. Able to place research in a wider context of development
  5. Able to link resource assessment to the behavior of producers, consumers and intermediaries involved in aquatic production

  • Student visits the specified area where house-hold small-scale aquaculture system exists.
  • Explore the characteristics of the small-scale aquaculture – inputs-outputs analysis; seed, feed, fertilizer, household labor, home consumption and sale (production)
  • Assess the impacts in house-hold rural livelihood
  • Report submission and presentation

7.2.   Feasibility assessment for promotion of an aquaculture system in different resource base context

  • Student visit new area where no aquaculture has been started
  • Assess the resources available
  • Plan an aquaculture activity
  • Report submission and presentation

7.3.   Field trip to Commercial production systems (Public / Private production and support system)

  • Understand the system – goal and objective of the farm, production systems and input-output characteristics, marketing channel.
  • Report submission and presentation
