The struggle effortsand success ofthe Turkish aquaculture industryfrom past to present have beeninvestigated with comparative evaluation of aquaculturetrends in Japan, a country with significant infrastructurein fish farming. Despite its long history of fish farming, Japanese aquacultureproduction has stabilized over the last twodecades, while Turkish aquaculture is in a rapid growth period, ranking among top producers in the world.The lower correlation between production and annual increase of population growth recorded for Japan (R= 0.795207) compared to the higher correlation for Türkiye (R= 0.930835), based on statistical data over the past 40 years, showedthat population growth has influence on fish farming yields. The increasing number of younger adults in Türkiye provide advantageous conditions for the selection of qualified personnel from a wider range with higher opportunities in theemployment of staff for the Turkish aquaculture sector. In Japan however, along with a variety of reasons, the industrialization has potentially shifted the interests towards technology-based businesses rather than marineworks. Introducing high-tech aquaculture systems might reattract young generations, that may help restructuring Japanese aquaculture business.Hence, this study provides useful indications for decision makers in the management of securing the future of the aquaculture industry by reducing the so-called generation gap in aquaculture recruitments.
