Tridge summary

A study led by Prof. Dr. Saadet Karakulak from Istanbul University's Faculty of Aquatic Sciences, as part of a project supported by the World Food and Agriculture Organization (FAO), has revealed a 20% decrease in sea snail stocks in the Black Sea over the past three years. This decline, attributed to increased fishing and the invasive species' impact on bottom habitats like black mussels, raises concerns about the necessity for sustainable fishing practices. The research also points out the need for revising fisheries management due to overfishing and damage to habitats, suggesting the use of selective fishing methods. Additionally, the study highlights the issue of microplastics in the sea, with recent findings indicating their presence in breast milk, underscoring the need to address marine pollution.

Researching the distribution of sea snails in 83 stations determined between İğneada and Sinop, Istanbul University Faculty of Aquatic Sciences Faculty Member Prof. Dr. Saadet Karakulak said, "We have been working in the Western Black Sea region for 3 years. If we compare the first year we went to the last time, there is a decrease of 20 percent. Certain restrictions are definitely needed to ensure sustainable fisheries." The distribution of sea snails, an invasive species carried by ships' ballast waters in the 1950s, in the Black Sea was investigated. Within the scope of the World Food and Agriculture Organization (FAO) supported project of Istanbul University Faculty of Aquatic Sciences, samples were taken from 83 stations determined between Igneada and Sinop. In the study, which also includes Bulgaria, Romania, Turkey, Georgia and Ukraine, it was determined that the stock of sea snails in the Black Sea decreased by 20 percent this year.
