Sustainable Aquaculture

CMM12C Elective Course 4 ECTS
Period -
Instructor Dr. Peter Krost


This course focuses on the interactions that take place between aquaculture and the environment by looking into the principles and concepts relevant to the ecology of aquaculture. Different aquaculture systems and production methods will be examined. The major theme will be environmental aspects of aquaculture, such as feed-stuff problems, alternative fish feed ingredients and IMTA approaches.


At the end of the course, students will be able to:

  • understand different aquaculture systems, production methods, breeding programs, as well as the common constrains involved in farming fish at different levels;
  • describe the components and processes of aquaculture systems that interact with the environment;
  • outline main regulations and typical environmental monitoring schemes, and understand the importance of public perception for aquaculture activities.



Peter Krost graduated in 1986 with a Diploma (master's) in biology from the University of Kiel, Germany. In 1990 he finished his PhD in marine ecology at the Institute for Marine Science (IfM, today Geomar) in Kiel, with a thesis on the impact of bottom fisheries on seafloor geochemistry and benthos in the Western Baltic. From 1990 to 1992, he was a postdoctoral fellow at the National Center for Mariculture in Eilat, Israel, studying environmental effects of fish farms on sediment and water quality in the Gulf of Aqaba. From 1992 to 1994, Peter Krost was researcher at IfM in Kiel again, and worked on the influence of sediment dredging and dredged material disposal on sediment biology and geochemistry.

In 1995, Peter Krost started, together with Christian Koch and Levent Piker, the company CRM, Coastal Research and Management; a company devoted to sustainable coastal development focusing on environmental impact assessments, sustainable aquaculture, and on the extraction of active substances from the sea. CRM started an algae farm in 1998 and has been running a mussel farm since 2010. Currently, Peter is heading the environmental impact study group, as well as of the aquaculture department.
