For the first time the organic substance of silts settling on the underwater base of breakwaters in Sevastopol and in Kamyshovaya bays (southwestern Crimea) was studied. On the eastern breakwater the content of total organic matter (TOM) varied from 14 to 36% (23% on the average) of the total silt mass and on the southern breakwater from 18 to 70% (38% on the average). Estimated on the inner and the outer side of the eastern breakwater the content of TOM is almost the same; on the outer side of the southern breakwater it is greater compared with the inner side that is probably due to the nearby sewage discharge outlet. Lipids are the largest fraction in the TOM on the southern breakwater and proteins on the eastern breakwater (43-44% and 4*5-37%, respectively).
