    An In-Depth Analysis of the Finfish Aquaculture in Türkiye: Current Status, Challenges, and Future Prospects
    (Wiley, 2025) Aydin, Ilhan; Ozturk, Rafet cagri; Eroldogan, Orhan Tufan; Arslan, Murat; Terzi, Yahya; Yılmaz, Sevdan; Diken, Guerkan
    Aquaculture emerges as a crucial solution for addressing the global food shortage of an estimated 10 billion people by 2050. In T & uuml;rkiye, aquaculture plays a significant role in supporting the economy and ensuring food security. Over the past two decades, finfish production in T & uuml;rkiye surged from 61,163 to 547,505 t, generating $1.7 billion in export revenue across over 100 countries. This growth has been driven by technological advancements, robust governmental support, and increasing global demand for aquaculture products. However, the sector also faces persistent challenges, including the need to enhance sustainability, mitigate ecological impacts, and manage finite resources. As Europe's leading fish producer, the Turkish aquaculture sector must continue to innovate and expand to meet the demands of a growing population. Despite the expanding research on Turkish finfish aquaculture, there is no comprehensive review that consolidates both scientific progress and sectoral developments. This study fills that void by combining a bibliometric analysis of 1958 scientific publications from 1983 to 2023 with an in-depth sectoral evaluation, providing a holistic understanding of the Turkish aquaculture sector. The bibliometric analysis highlights key research areas, trends, and knowledge gaps, while the sectoral overview examines production trends, dynamics of the feed industry, technological innovations, and economic factors. It also addresses challenges such as climate change impacts, reliance on imported feed ingredients, and disease issues, discussing potential avenues for sustainable growth through innovation, policy reforms, and technological integration. This review serves as a valuable resource for researchers, policymakers, and industry stakeholders, offering insights into the current state and future directions of finfish aquaculture in T & uuml;rkiye.

    Melatonin Implantation in Preovulatory Rainbow Trout (Oncorhynchus mykiss) under Short Photoperiod Regime Reduces Egg Quality
    (Central Fisheries Research Inst, 2014) Sonmez, Adem Yavuz; Aydin, Ilhan; Hisar, Olcay; Kaya, Hasan; Hisar, Sukriye Aras
    As in other vertebrates, the pineal organ in salmonids receives photic information directly through specialized photoreceptor cells to synchronize both daily and seasonal behavioral and physiological events, including the reproductive. In this study, the effect of a melatonin implantation before the preovulatory period on egg quality was investigated in rainbow trout (Oncorhynchus mykiss) adults. Fish were exposed to two different lighting regimes [(constant short photoperiod (SP) of 6h light/18h dark) or natural photoperiod (NP) of 9h light/15h dark) with sub groups receiving a slow-release melatonin implant ((containing 9 mg melatonin hormone (MLT)) or sham implant. Melatonin implanted fish showed supraphysiological plasma MLT concentration during the 45 days after implantation. The spawning period started at the same time in all groups after implantation, although eggs were obtained from females exposed to SP lighting regimes only or SP lighting regimes plus implanted MLT exhibited significantly lower quality characterized by lower hatching rate and survival to first feeding than that of females expose to NP. In conclusion, it was determined that implantation of MLT in preovulatory rainbow trout females causes a decrease in egg quality. However, future investigations should be conducted to ascertain the MLT dose required for and time of implantation in rainbow trout.
