Abstract: To‘dako‘l suv omborida muhim ovlanish ahamiyatiga ega bo‘lgan invaziv tur — kumush tovonbaliqning(Carassius gibelio) “truss-protocol” bo‘yicha o‘sish ko‘rsatkichlari o‘rganildi. Kumush tovonbaliqning tangachasi sikloid,yirik tangachalari mavjud. Tangacha o‘lchami (v, okulyar-mikrometr birligi) va tanasining standart uzunligi (SL, sm) o‘rtasidato‘g‘ri chiziqli ijobiy bog‘liqlik mavjudligi aniqlandi (v = 1,89 * SL + 3,0459; r = 0,75). Namunalardagi baliqlar tanasiningstandart uzunligi 10,1–30,5 sm ni va 1–4 yoshni tashkil qildi. Tanasining standart va umumiy uzunligi (TL, sm) o‘rtasidagibog‘liqlik quyidagi regressiya tenglamasi bilan tasniflanadi: SL = 0,819 * TL + 0,183 (r = 0,99). Tanasining umumiy og‘irligi(W, g) tanasining uzunligi bilan ijobiy bog‘langan: W = 0,018 * SL³,16 (r = 0,96). Kumush tovonbaliqning o‘rtacha o‘sishsur‘ati: SL1 – 10,7 sm, SL2 – 18,1 sm, SL3 – 24,4 sm, SL4 – 26,1 sm. Roza Li fenomeni kuzatiladi.
