Objectives of the Course
The aim of this course in fish feeding organs and organelles about what their mission is, how are nutrients from feeding to teach. Also obtain that fish physology and biochemistry. In addition, the nutrients in fish and energy resources as the basic nutrients of protein, fat, carbohydrates and growth have an impact on makronütrientler as vitamins, minerals, micronutrients and their lack of such information is given about.Fish feed used in the production of raw materials recognition ability, raw materials production technologies, learning ability, and these substances recognition ability, fish feed production stages of learning ability, these stages are used in systems operating principle, mechanical equipment, learn about the properties can and feed production stages that may arise problems, knowing the precautions and implement necessary procedures to recognize the fish feed used in making the calculation methods of learning ability and application can, to provide.

Course Contents
In this course, the fish feeding habits that vary depending on the digestive system physiology, anatomy, digestive effects of the other factors is discussed, as well as the digestive system and organs to work that energy to the subject are placed separately, energy use are important in metabolism, excretion and growth issues are discussed. In addition, the nutrients in fish and energy resources as the basic nutrients of protein, fat, carbohydrates and growth have an impact on makronütrientler as vitamins, minerals, micronutrients and their lack of such information is given about. Our country's food industry and amount of fish feed production information given, nutrition and feed technology laboratories devices used, the equipment and the analyses introducing feed and feed raw materials of the presentation and classification, feed additives examination and identification, mixed feed production technology and systems to introduce feed storage, transport and handling of the investigation, feed production systems evaluation-silos, weighing, storage, screens, mixers, mills, packaging, systems analysis, forming systems-pressed pellet, extruder definition, the other forming systems analysis and comparison, drying, lubrication annealing, system identification, quality control methods can be described, to prepare feed formulations and examples of applications made.
