Abstract

Ushbu maqolada Farg'ona viloyatining turli gidrologik rejimga ega bo'lgan tabiiy daryo-soy tarmoqlari, sug'orish-kollektor tizimlari, predgorli yirik suv omborlari (Andijon, Karkidon, Kayrakkum) hamda intensiv baliqchilik xo'jaliklari baliqlarida parazitlik qiluvchi Nematoda va Trematoda sinfi vakillarini yig'ish, fiksatsiya qilish, laboratoriya sharoitida preparatlar tayyorlash hamda ularni taksonomik jihatdan identifikatsiya qilishning zamonaviy metodologik asoslari tizimlashtirilgan. Tadqiqotda ixtioparazitologiyada keng qo'llaniladigan to'liq parazitologik yorish, kompressor usuli hamda gelmintlarni kimyoviy-morfologik ishlov berish (alum-karmin bilan bo'yash, sut kislotasi va glitserinda shaffoflashtirish) metodlarining amaliy ahamiyati yoritilgan. Farg'ona vodiysi gidroekotizimlarida parazitofaunaning shakllanishiga ta'sir etuvchi ekologik va abiotik omillar (suv oqimi tezligi, antropogen yuklama, suvning loyqaligi va gidrologik srabotka) uzoq yillik monitoring ma'lumotlari asosida tahlil qilingan. Aniqlangan parazit faunaning, jumladan, Diplostomum va Rhabdochona urug'i vakillari mintaqa ekologik sharoitidagi invaziya ko'rsatkichlari (IE, II) qiyosiy muhokama qilingan.
