Questa ricerca è il risultato di: 1- Indagini sull’alimentazione degli avannotti di carpa argentata (Hypophthalmichthys molitrix) con particolare attenzione ai fitoplancton dominanti; 2- Determinazione degli effetti delle microalghe Diatoma e Chlorella sui parametri di crescita e sul tasso di sopravvivenza dei giovani esemplari di carpa argentata (Hypophthalmichthys molitrix); 3- Identificazione, purificazione e preparazione delle microalghe raccolte.Sulla base degli studi condotti sulla parte iniziale e finale del loro intestino e sull’acqua dello stagno, gli avannotti fitofagi si nutrono di fitoplancton, zooplancton e detriti. Tuttavia, la loro alimentazione essenziale era costituita da fitoplancton e detriti. I gruppi planctonici erano formati da Cyanophyta, Chlorophyta, Bacillariophyta ed Euglenophyta. Oltre a questi quattro gruppi, nell’acqua dello stagno erano presenti anche le pirofite. L’abbondanza relativa di questi organismi nutritivi nell’acqua e nell’intestino era diversa. Inoltre, nella maggior parte dei casi è stata osservata una relazione diretta tra l’intensità degli organismi acquatici e gli ingredienti intestinali. Sulla base di questo studio, sono state osservate differenze essenziali nella digestione a seconda della fonte di nutrimento e le differenze maggiori sono state riscontrate nella digestione di Bacillariophyta, Cyanophyta e Chlorophyta.
