The paper is devoted to alien fish species that have appeared in coastal waters of the Black Sea near Crimea for the past 50 years. The fish fauna of the Black Sea mainly comprises species that represent the Ponto-Caspian and Atlantic-Mediterranean faunal complexes. According to the generalised literature data, 158 fish species of 107 genera of 60 families have been recorded in the Black Sea since the publication of K. F. Kessler’s work (Kessler 1877), all of them representing the Atlantic-Mediterranean complex. In waters of Crimea, 116 species of 86 genera of 51 families have been recorded for the same period. A full checklist of fishes of this complex is presented indicating 31 alien species that have appeared since the 1970s and which belong to 27 genera and 16 families. In waters of Crimea, alien fishes make up 26.5 % of all species, 31.0 % of all genera, and 31.4 % of all families of the Atlantic-Medirranean complex. According to the level of their occurrence in marine waters of Crimea, all recently introduced species are grouped into three categories: regular, sporadic, and casual. Their brief characterisics are given, including synonymy, representation in the fish collection of the NMNH NASU, brief description, distribution, and vector of introduction. It was found that benthic species predominate among introduced fishes that occur regularly in waters of Crimea (12 species, or 80.0 %), while bentho-pelagic and pelagic species are less represented (6.7 % and 13.3 %, respectively). Pelagic and bentho-pelagic species prevail (50.0 % and 37.5 %, respectively) among fishes that occur sporadically. Bentho-pelagic species predominate (57.1 %) among fishes that occur casually. It was discovered that among the 31 alien fishes recorded in the Black Sea waters of Crimea for the past 50 years predominate those that have appeared here due to the natural process of mediterranisation (22 species, 71.0 %). It was imposibble to determine the vector of introduction of 4 species (12.9 %). The appearance of 5 species, which represent 16.1 % of all alien species, is related to anthropogenic factors. It can be also concluded that benthic species predominate among the alien fishes (14 species, or 45.2 %), while bentho-pelagic (9 species) and pelagic (8 species) fishes make up 29.0 % and 25.8 %, respectively. Of the 31 introduced fishes, 10 (32.2 %) have naturalised and acclimatised in marine waters of Crimea and have founded independent breeding populations. Among them, representatives of the family Gobiidae notably prevail, followed by the taxonomically close family Oxudercidae, whereas one species belongs to the family Blenniidae. The so-iuy mullet, which is the only representative of the pelagic ecological group, was introduced intentionally.

The Monrovia Surgeonfish Acanthurus monroviae Steindachner, 1876 is reported for the first time in the Black Sea off the southwestern coast of Crimea (44°29.5ʹN; 33°35.5ʹЕ). The single specimen was caught by the commercial trap net on September 19, 2018; its standard length was 195 mm. The most realistic version of its occurrence is the self-penetration of this specimen into the Black Sea from the Mediterranean Sea. Over the past 20 years, twelve fish species that had not previously been met in the Black Sea were registered near the southwestern coast of Crimea.

In this study, the fish species inhabiting the Bolaman Stream drains to the Black Sea from the Fatsa coast (Ordu Province, Turkey) was reported for the first time. The study was caught out non-periodically by sampling from seven stations in the Bolaman Stream between July 2017 and November 2018. Fish samples were captured with an electroshock device. With this study, it was determined that the fish fauna of the Bolaman Stream is represented by 10 species in five families (Acheilognothidae, Cyprinidae, Gobiidae, Leuciscidae, and Salmonidae). These species were as follows, respectively Rhodeus amarus, Barbus tauricus, Capoeta banarescui, Neogobius fluviatilis, Ponticola turani, Alburnus derjugini, Squalius cephalus, Vimba vimba, Alburnoides fasciatus, and Salmo coruhensis.

Abstract. Regular observations in the Black Sea basin started in the past century, and quite good multidisciplinary observing system operated in the 70–80ies based on the ship observations. Modern oceanographic observing system in the basin is built according to the GOOS principles. It includes space remote sensing observations, data of free floating buoys and costal observational network. Integration of the observing system and its real-time operation were started within the framework of the FP5 ARENA project and later were improved during the FP6 ASCABOS project. The coastal observing system which includes time series from the coastal platforms and multidisciplinary surveys of the coastal areas fulfilled by the research vessels was set up during the ECOOP. Paper describes all components of the Black Sea observing system operated during the ECOOP project and its applications in the framework of the project.

The South Caucasus (SC) region is recognized for its high biological diversity and various endemic animal taxa. The area has experienced many fish introductions over the years, but the overall information about non-native fishes in the three SC countries, Armenia, Azerbaijan, and Georgia did not exist. Although these three countries belong to the Kura River drainage, Caspian Sea basin (only the western half of Georgia drains into the Black Sea), the legislative framework for each country regarding introduction of non-native fish species and their treatment is different and poorly developed. The goal of the present study was to make an initial inventory of non-native fish species in the three SC countries, and summarize the existing knowledge as a basis for future risk assessment models and formulation of regional management policies. Here, we present a unified list of 27 non-native species recorded in the wild in Armenia, Azerbaijan, and Georgia. Among these 27 species, eight were translocated from the Black Sea basin to the Caspian Sea basin. Out of these 27 non-native fishes, 15 species have become established (three of them being considered invasive) and six fish species could not survive in the wild.

Aim The unique aquatic Pontocaspian (PC) biota of the Black Sea Basin (BSB) is in decline. Lack of detailed knowledge on the status and trends of species, populations and communities hampers a thorough risk assessment and precludes effective conservation. This paper aims to review PC biodiversity trends using endemic molluscs as a model group. We aim to assess changes in PC habitats, community structure and species distribution over the past century and to identify direct anthropogenic threats. Location Black Sea Basin (Bulgaria, Romania, Moldova, Ukraine and Russia). Methods Presence/absence data of target mollusc species was assembled from literature, reports and personal observations. PC biodiversity trends in the NW BSB coastal regions were established by comparing 20th and 21st century occurrences. Direct drivers of habitat and biodiversity change were identified and documented. Results A very strong decline of PC species and communities during the past century is driven by a) damming of rivers, b) habitat modifications negatively affecting salinity gradients, c) pollution and eutrophication, d) invasive alien species and e) climate change. Four out of 10 studied regions, namely, the Danube Delta – Razim Lake system, Dniester Liman, Dnieper-South Bug Estuary and Taganrog Bay-Don Delta contain the entire spectrum of ecological conditions to support PC communities and still host threatened endemic PC mollusc species. Distribution data is incomplete, but the scale of deterioration of PC species and communities is evident from the assembled data, as are major direct threats. Main conclusions PC biodiversity in the BSB is profoundly affected by human activities. Standardised observation and collection data as well as precise definition of PC biota and habitats are necessary for targeted conservation actions. This study will help to set the research and policy agenda required to improve data collection to accommodate effective conservation of the unique PC biota.

The steppe which stretches between the Lower Danube and the Black Sea, from the Delta southward as far as the foothills of the Emine Dagh, and which since the middle of the 14th century has been called, after the Bulgarian prince Dobrotitsa, the Dobruja, is the homeland of a small Turkish-speaking people, the Gagauz. It is because of their religion that they appear as a distinct group among the Turks: they are Christians belonging to the Greek Orthodox Church. In the past the Gagauz may have constituted, among the various ethnic elements of the region, a group of considerable importance, especially in the southern and middle Dobruja, from Varna and Kaliakra towards Silistria on the Danube. Besides, small isolated groups of them are to be found also in the Balkans (where they are more commonly known by the name of Sorguch): in Eastern Thrace, round Hafsa, to the south-east of Adrianople, and in Macedonia, to the east and west of Salonica, round Zikhna (near Serres) and round Karaferia (Verria). In modern times the Gagauz of the Dobruja have shrunk to a feeble minority chiefly as a result of a prolonged and massive emigration into Bessarabia. To-day even this remnant is rapidly dwindling.

Hans Lissmann overcame extraordinary difficulties to become one of the pioneers of experiments on animal locomotion and the discoverer of the electric sense of fishes. The Russian Empire He was born on 30 April 1909 at Nikolayev, a Black Sea port near Odessa. Most of what we know of his early life comes from two typewritten memoirs, written in 1944 when he was interned. He was the younger of the two sons of German parents, Robert Lissmann, an exporter of grain, and his wife Ebba. A photograph taken in 1913 or 1914 shows a prosperous family formally posed with the boys dressed immaculately and impractically, entirely in white. Until Hans was five the family lived in Nikolayev and in Novorossiysk, another port on the northern shore of the Black Sea. He spoke Russian with his parents and French with his grandparents. Then, after the outbreak of the First World War in 1914, the family was sent to Kargala, a village near Orenburg on the edge of the Urals, 1100 miles north-east of Nikolayev. There they were interned as aliens among a population of Tartars, Bashkirs and Kirghis. Hans learned some Tartar, and was also taught German. Drawings that he made there show a village of log buildings inhabited by men in turbans, and a rider on a Bactrian camel. Their mother taught the boys arithmetic and languages, and arranged for them to be introduced to biology by an interned zoologist and a botanist who took them into the surrounding countryside on summer afternoons. She supported the family by teaching in the village school when her husband was arrested and taken away for several months. The Russian Revolution came, and Kargala was captured and recaptured several times by the Reds and Whites.
