The aim of the course:
Providing data to analytically monitor the conditions of living marine and inland water resources that we use economically, to determine the effects of environmental effects such as hunting and pollution on the operated resources, to take fisheries management measures, to ensure sustainable use of the ecosystem, and to calculate the rental prices of water reservoirs to be leased.
 
Learning OutcomesCTPOTOA
Upon successful completion of the course, the students will be able to :
LO - 1 : -learn to use the tools and working principles required for stock estimation methods.12,13,14,191,6,
LO - 2 : - comprehend the methods that can be used in seas and inland waters 12,13,14,191,6,
LO - 3 : - learn to collect essential data and use meta data for some methods,12,13,14,191,6,
LO - 4 : - apply some stock estimation methods, and take part in teamwork for some others12,13,14,191,6,
LO - 5 : - propose measures for fisheries management based on the results obtained12,13,14,191,6,
LO - 6 : - understand and interpret the results of the completed other project12,13,14,191,6,
