The negative effect of advantages of new species into Issyk Kul Pond and its effect on the livelihoods of local people and the environment. Introduction
Issyk Kul is usually popular tourist destination in Kyrgyzstan. Visitors from Central Asia, Spain and The european union come to enjoy the impressive view and the serenity with the lake between humongous mountains of Tianshan. It is viewed as the treasure of the nation. 10% of the country's GROSS DOMESTIC PRODUCT is offered by tourism sector, and 9% of computer is caused by Issyk Kul lake travel and leisure industry. The neighborhood residents rely on seasonal income from tourism industry, nevertheless the season is pretty short no more than 3 months.
Lake and biodiversity.
Issyk Kul is definitely endorheic lake, which means it lies in the basin inside the mountains. The lake is definitely supplemented by 118 tiny rivers and streams via melting snow caps, but does not offer an outflow (see picture 1). Although there is a theory that this might have the outflow somewhere deep in underground, that yet needs to be studied. Its length is usually 182 kilometres and thickness of 70 km, the coverage region is 6236 square km, altitude of 1609 m above ocean level and it is second major high altitude pond in the world following Lake Titicaca in South America. The water, in generally, never freezes for its level of salinity. The study was done to gauge the level of salinity and this shows that the level varies from 5. 5 to 7. 0% depending on the site where the test was taken and seasonality. After heavy rains, for example , the level of salinity show as little as 2%. During winter months the water temperature is definitely 5 to 6В°C, on the shallow areas in northern part of the ponds the water occasionally freezes. Biodiversity of the Issyk Kul location consist of 1500 species of plant life, 30 types out of it are very important wild medical plants; wide array of mammals (54 species), parrots (267species) and 28 types of fish, 14 out of it happen to be indigenous and 7 complete species and 1 subspecies are endemic to the pond. In the local dish fauna of Issyk Kul there have been no potential predators. In the late 1954s the local scientists suggested which the fish share quantity of the lake may be increased and as well as the product quality improved. Supposedly, the introduction of the predator kinds like Sander Lucioperca will need to somehow boost the fishing output of the pond. With that theory in sixties there was big scale of works of introduction of new atypical kinds into Issyk Kul seas. In the list of introduced types were Pike-perchВ Sander lucioperca, Oriental BreamВ Abramis brama orientalis, Grass Carp [Ctenopharyngodon idella] and TenchВ[Tinca tinca ] while others. The decision was performed without complete study and deep analysis. For example , Pike perch Sander luciperca is typical predator fish. It can be nutrition contains 80-90% of small fish and is lively year about. Its inhabitants growth taken to decreasing of usual fish stock in the area. Although the local citizens are proud of the pond, but they are not aware of the decreasing in numbers endemic seafood they have and just how their fishing activities can affect them. Even though the pike-perch and oriental light were well adjusted for the new environment, the Range Trout [Onchorhynchus mykiss], the Sevan Trout as well as the Common Whitefish needed a few supporting to keep up their populace. These are the predators, which will endangered endemic species just like Issyk-Kul Marinka [Schizothorax pseudoaksaiensis issykkuli] and Naked OsmanВ[Gymnodiptychus dybowski]. During newest studies just naked osman was noticed in the lake and the Issyk Kul Marinka almost vanished. Conservation activities for the Issyk Kul area have been completely undertaken for approximately 60 years. Beginning 1970 the fishing actions in the area were limited, no fishing near waterfowl concentrations in the wintertime times, mainly in the shallow bays with the lake. The agriculture actions were completed near the shoreline lines from the lake just before, but now it has stopped and it reveals positive impact on the development of plants and creatures of the Issyk Kul....
