A Comparative MCDM Analysis of Potential Short-Term Measures for Dealing with Mucilage Problem in the Sea of Marmara

Mucilage is a dense and highly viscous substance made up of extracellular polysaccharides produced secreted by the overgrowth various aquatic species. Rising ocean temperatures, as well human-induced stressors like inadequate treatment levels overfishing, are common causes such algal blooms. By mid-2020, Sea Marmara was covered with mucilage that threatens marine life, tourism, fisheries economy. Even though this not first outbreak in region-specific occurrence, it one worst. The phenomenon attracts increasing attention severely impacts overall ecology, particularly benthic creatures. This study aims to evaluate short-term strategies can be used control according environmental, economic, technological, technical social criteria. It important note although integrating conventional plants advanced nutrient technologies long-term ultimate solution issue, focuses only on measures Marmara. Fuzzy Theory analyze data obtained from experts sectors using two separate Multi Criteria Decision Making (MCDM) models: Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) Technique Order Similarity Ideal Solution (TOPSIS). results indicate stopping fishing best alternative, whereas collecting surface second-best preferable methods (F-TOPSIS, F-PROMETHEE). According experts, third option use beneficial bacteria eliminate mucilage, while reactive oxygen dosing least appealing option.
