Annotatsiya

So‘x daryosi ixtiofaunasiga mansub 14 turning uzunlik-og‘irlik munosabatlari (LWR) va to‘yinganlik indeksi tahlil qilindi. Natijalarga ko‘ra, 3 tur izometrik (b=3), 1 tur (Triplophysa strauchii) manfiy allometrik (b<3) va 10 tur ijobiy allometrik (b>3) o‘sish xususiyatiga ega ekanligi aniqlandi. Turlarning to‘yinganlik holati Fulton indeksi (K) orqali baholanganda, Hemiculter leucisculus, Triplophysa daryoae hamda Triplophysa strauchii turlarida K qiymati 1 dan past ekanligi, aksincha, Carassius gibelio, Cottus spinulosus, Leuciscus squaliusculus hamda Rhodeus ocellatus turlarida 1 dan yuqori ekanligi kuzatildi. Barcha turlar uchun o‘rtacha nisbiy to‘yinganlik indeksi (Kn) 100,51±10,075 ni tashkil etdi.
