Susceptibility to metazoan parasite infection in amphimictic diploid and induced triploid tench (<i>Tinca tinca</i> L., 1758): the role of parasites in fish aquaculture.

ABSTRACT:

Introduction

Artificial induction of polyploidy in fishes is a widely used method in commercial aquaculture due to its economic potential and its association with changes in cell morphology and physiology that can significantly affect individual fitness. Using tench (Tinca tinca, Cyprinidae), a fish species extensively farmed in European aquaculture, we investigated differences in parasite susceptibility between triploid and diploid fish and analyzed the potential effect of metazoan parasite infection on fish condition, physiology, and health status.

Methods

Amphimictic diploid and induced triploid specimens collected from a breeding pond were examined during four sampling events over the course of one year, focusing on the presence of metazoan parasites and selected
