    Effect of Fish Farming on Bioecological Characteristics of the Mediterranean Mussels Mytilus galloprovincialis Lamarck, 1819 (Bivalvia: Mytilidae): Güllük Bay Example, South Aegean Sea, Turkey
    (Institute of Biodiversity and Ecosystem Research - Bulgarian Academy of Sciences, 2024) Yildirim, Pinar; Ercan, Ertan
    This study was carried out to determine the effects of cage cultivation on bioecological characteristics of Mytilus galloprovincialis in Güllük Bay Kazikli Port between May 2013 and May 2014. An integrated multi-trophic aquaculture method was used. The growth and survival rates, age structure and reproductive success of mussels as well as water quality parameters and phytoplankton composition were monitored monthly in two selected stations. Mussels belonging to different size groups exhibited high growth and survival rates during the summer and spring when the temperature was high near the offshore systems. Applying a length-frequency analysis graph created using the shell growth limits, it was found that the mussels reached the marketing length (>50 mm) in 18 months. With this study, it has been revealed that mussel development continued in both stations and the region was suitable for potential mussel farming. © 2024 Institute of Biodiversity and Ecosystem Research - Bulgarian Academy of Sciences.

    INTERACTION BETWEEN AQUATIC BIVALVE SPECIES AND GLOBAL CLIMATE CHANGE
    (Ahmet Ali SÜZEN, 2022) Yıldırım, Pınar; Ercan, Ertan; Bahrioğlu, Ergi
    Climate changes affect the bio-ecological characteristics of living things in aquatic ecosystems. It is the main factor in accelerating the geographical distribution of species, especially by triggering species invasions. Also, climate change is important as it increases the risk of infection between species. Bivalve species are among the important fishery species due to their high nutrient content, widespread distribution in aquatic ecosystems, rapid growth, and ecological and commercial values. Climate change and its effects have caused some invasive bivalve species, which can spread rapidly in aquatic environments, to be included in the list of biological pollutants due to their ecological and economic effects. In this review, the role of climate change in the growth performance, economic and ecological effects of bivalve organisms and the sustainable alternatives that can be applied at the solution point were evaluated.
