Anthropogenic sources of mortality should be managed to avoid further declines in the species. There are two primary theories. The Caspian seal population is currently estimated to be around 100,000 -- less than 10 percent of what it was a century ago. related loss of sea ice, and bycatch in from industrial fishing nets.

It is a land locked water body located on the border of two large parts of the continent of Eurasia. Seals. INTRODUCTION Recent studies of the Caspian seal (Phoca caspica), which is endemic to the Caspian basin, have given rise to concern over the conservation status of this species (1-7). Further studies are required to determine if the latter species are infected with a canine dist emper virus genetically similar to that found in the seals. The Caspian seal is a unique marine mammal and it is found nowhere else in the world, but in the Caspian Sea bordered by Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan, and while its population was estimated to be one million a century ago, today the situation is drastically different. The population decline over the past 150 years is directly related to intensive and unsustainable hunting, which has been ongoing since the mid-18th century, with tens of thousands of seals killed on the breeding grounds on the winter ice-field every year. However, at present there are only around 7 to 15 thousand breeding females, meaning the population has very low reproductive capacity. Current deaths still greatly exceed the introduction of young into the population. Although there has been significant progress towards reducing illegal hunting, The Caspian seal population has decreased by more than 90% since the start of the 20th Century and continues to decline, considered to be due to commercial hunting, habitat degradation (through introduction of invasive species), disease, industrial development, pollution and fishing operations using nets.
