ECOLOGICAL CHANGES IN THE SEA OF MARMARA, Melek İşinibilir,Ahmet E. Kıdeyş,Alenka Malej, Editör, Istanbul University Press, İstanbul, ss.779-817, 2024
This study reveals the fishing trends of important species caught in the Sea of Marmara between 1970 and 2021
using LOESS regression analyses. Out of the 24 species studied, it was found that 23 of them experienced a
significant decrease in fishing quantities. Only ‘deep-water rose shrimp’ showed no decline and maintained a
relatively stable trend. Formerly commercially important species such as bluefin tuna, swordfish, striped venus
clam, and oyster were found to no longer be targeted for fishing. There has been a noticeable decline in the fishing
quantities of these species, especially after the year 2000. Establishing sustainable fishing while preserving the
health of the aquatic ecosystem requires effective fisheries management, which primarily relies on well-planned
strategies. Therefore, it is crucial to have knowledge of parameters such as biomass, recruitment, and fishing
mortality rates when developing an effective management plan. As part of the Mediterranean basin, the Sea of
Marmara, where stocks are heavily exploited and rapid warming occurs, is particularly vulnerable to anthropogenic
and environmental stressors, especially in recent years. Consequently, it is of utmost importance to create a specific
fisheries management plan for the Sea of Marmara and adopt ecosystem-based fishing principles that aim to enhance
the social, economic, and institutional aspects of fishing while ensuring its sustainability.
