Приводятся данные о численности малого лебедя (Cygnus bewickii) на зимовке в туркменской части Каспийского моря в журнале "Проблемы освоения пустынь", № 3-4 за 2021 г., стр. 57-60. Как показано в статье, данный вид эпизодически встречается здесь с января 1977 г. Наибольшее число – 322 особи, зарегистрировано в январе 2019 г., тогда как в январе 2020 г. было учтено только 57 птиц.

В настоящей работе даётся анализ динамики численности каспийского тюленя в Туркменском секторе Каспийского моря. Показаны места встреч и данные учётов по сезонам и годам. Обсуждаются лимитирующие факторы, причины гибели и вопросы сохранения.

In accordance with Article 18 (2) of the Tehran Convention, the Parties developed the Strategic Convention Action Programme (SCAP). The SCAP is a comprehensive, long-term agenda and framework for the implementation of the Tehran Convention and its Protocols over a period of 10 years.

We are pleased to announce the publication of the Proceedings of the Scientific Conference on the Climate Change in the Caspian Sea region. This collection includes all the abstracts selected by the Organizing Committee of the Conference. In addition, in the Proceedings you will find introductory words by key speakers of each section and welcome addresses from the guests of the Conference.

Scientific Conference on 27 and 28 October 2021 brought well over 80 leading scientists from the countries bordering the Caspian Sea together, to take stock and give a boost to research in the region underpinning the climate change policies and actions of Azerbaijan, IR Iran, Kazakhstan, Russian Federation and Turkmenistan.

The Ural sturgeon yield-to-fishery relative to river discharge was the highest in the Caspian Sea till recently. The environmental conditions to secure natural reproduction are still satisfactory for successful sturgeon reproduction. However, nowadays the catch in all regional sturgeon species is negligible. The Ural sturgeon population dynamics are analyzed along with some anthropogenic and natural factors affecting them. It is argued that legal overfishing (including all legal means of fish removal), based upon (a) faulty estimations of sturgeon stock and catch limits and (b) inappropriate fishery policies are the principal reasons for the stock decline in the Ural. The maintenance of the natural reproduction in the Ural is considered to be the primary strategy for the stock replenishment. If used at all, artificial propagation should be used only as an additional secondary option exclusively at the historical sturgeon habitats upstream the Ural river and not in the river delta, where the hatcheries are located now. Transboundary cooperation of basin countries with active inter- national involvement is essential to prevent further deterioration of the situation. ***The attached copy is furnished to the author for non-commercial research and education use, including for instruction at the author’s institution, sharing with colleagues and providing to institution administration.
