The main goal of this study was to reveal the basic and supportive activities that should be included in the value chain for trout farming in Turkey and to perform a value chain analysis of trout farming. The concept of value chain was first used in the 1960s and 1970s by analysts who charted development paths for mineral-exporting economies. Since the 1990s, value chain analysis has been widely applied across other industries. The value chain consists of the activities required from the inception of a product or service (from the idea and design stage) through the different production stages (by combining the inputs of physical transformation and various producer services), to reaching the end consumers and eliminating it after use (including recycling). The value chain; consists of two main parts: primary activities (incoming logistics, operations, outgoing logistics, marketing and sales, services) and supporting activities (firm infrastructure, human resources method, technology development, supply). The value of this work; was to reveal the value chain map of the trout farming sector and determine the product flow along the value chain across the various stages. This study was the first of its kind within the field of fisheries among the value chain analysis applications in the national literature.
The knowledge developed by this study consists of primary data and secondary data obtained from interviews with stakeholders in the trout farming sector in inland waters (lakes and streams). First, the value chain of the trout farming sector was mapped, and the main actors and stakeholders in the sector were identified, and the entire product flow from production to the end consumer was defined. The basic and supporting activities in the value chain of trout farming in Turkey were determined based on the value chain model of Porter (1985). Five basic activities and their sub-dimensions and four supporting activities and their sub-dimensions in the value chain model of Porter (1985) were examined, supported by the information obtained from the actors and stakeholders in the trout farming sector in our country.
