Course objectives

The main objectives of this course are to enable students to understand and implement good practices in seafood handling processes by understanding the principle” from catch to fork”; selection of appropriate methods of conservation and implementation of good manufacturing practice during the different seafood processing technologies.

Course enrolment requirements and entry competences required for the course

Competence in applying knowledge of inorganic and organic chemistry and microbiology and biochemistry.

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, the students will be able to:
- identify all phases of post mortal changes in fish meat;
- identify and analyze metabolites of specific spoilage microorganisms
- implement different methods of preservation of fishery products in accordance with good manufacturing practice;
- define and implement the necessary methods of assessing the quality of raw material, technological processes and final products of fish processing industry.
- calculate the norms/yields necessary for the organization of production in the fish processing industry
- identify and eliminate problems in the technological processes
- identify critical control points in the production processes, carry out hazard analysis for different technologies and preventive and corrective measures to ensure food safety
- Independently implement HACCP plan.

Student responsibilities

Students are required to attend classes (lectures and exercises), actively participate in the teaching process and pass the exam (or 2 tests). The presence at lectures will be recorded, and absence needs to be justified. One hundred percent presence in class will be rewarded with 2 extra points at the test.

Screening student work (name the proportion of ECTS credits for eachactivity so that the total number of ECTS credits is equal to the ECTS value of the course):

Class attendance




Practical training


Experimental work








Seminar essay






Oral exam




Written exam






Grading and evaluating student work in class and at the final exam

Continuous evaluation through two tests during the semester (*):
Class attendance, A1 (success 80 = -100%), proportion in final grade, k1 = 0.1
Laboratory and field exercises, A2 (success = 60 -100%), proportion in final grade, k2 = 0.15
Seminar + presentation, A3 (success 60 -100%), proportion in final grade, k3 = 0.15
I. test, A4 (success 60-100 %), proportion in final grade, k4 = 0.30; II. test, A5 (success 60 -100%), proportion in final grade, k5 = 0.30
Final grade (%) = 0,10A1 + 0,15A2 + 0,15A3 + 0,30A4 + 0,30A5
Final evaluation through comprehensive written and oral exams (**) is carried out at regular examination periods through four examination terms. Activities A1, A2 and A3 are measured in the same manner as above. Written exam, A6 (success 60 -100%), the proportion of evaluation, k6 = 0.20; Oral examination, A7 (success 60 -100%), the share of the assessment, K7 = 0.40
Final grade (%) = 0,10A1 + 0,15A2 + 0,15A3 + 0,20A6 + 0,40A7 (50 -64% - sufficient (2); 65-75% - good (3); 76-89% - very good (4); 89-100% - excellent (5).
If the student has passed only one test (*) during continuous evaluation he/she is required to take the comprehensive exam (**) in the regular examination periods and the passed test will be acknowledged by the end of the academic year as part of a written exam.

Quality assurance methods that ensure the acquisition of exit competences

Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
