Transplantation in Lillafüred

On February 15-16th, Jelena, Zoran and Ákos spent two days at the Lillafüred Trout Farm conducting experiments on the isolation of rainbow trout spermatogonia and their transplantation into tiger trout recipients. Tiger trout is a hybrid of brown trout (Salmo trutta m. fario) and brook trout (Salvelinus fontinalis) and is supposed to be sterile, making it an ideal recipient for transplantation experiments. The transplantation experiments went according to plans, spermatogonia were injected into 205 tiger trout larvae. We are grateful to the manager of the trout farm, Mr. György (Gyuri) Hoitsy and his son Márton (Marci) Hoitsy for their hospitality and assistance during the work and for rearing the fish for our experiments.
