General competencies

The module enables the understanding of the basic processes in the freshwater and the sea water. The student acquires basic knowledge of geology, physics, chemistry and biology of inland and the sea waters, their significance in the fishery, and the ability to self-determination of the assessment of water pollution.

Types of instruction

  • Lectures
    Lectures are performed by assoc. Prof. Marina Piria and prof. dr. sc. Tomislav Treer.
  • Laboratory practice/exercises
    Three exercises related to physical and chemical properties of water and biological indicators related organisms will be performed. Exercises are performed in groups of a maximum of 10 students.
  • Field work
    Students gets basic knowledge about field sampling of water and bentic macroinvertebrates in inland waters and how to transport samples to the laboratory.
  • Seminars
    Seminars are research by students on the topic of physical and chemical properties of water. They are made in a team of up to five students per seminar. Students taking water samples, analyzing water in the lab, describe the results and discuss the literature. At the end of the semester students presenting their work in the form of poster presentations (three slides Microsoft PowerPoint applications) no more than 5 minutes.
