Abstract :
Abstract Many organisms such as parasites cause damage to fish. Lack of legislature and perception for aquatic disease led to the expansion of many dangerous diseases. In some cases, his has lead to the collapse of aquaculture in some countries. One of vectors the parasite infection are nonindigenous fishes. This study had carried out to survey on gastric infection of amorcheh (Pseudorasbora parva) by plerocercoid of Ligula intestinalis inZabol Chahnimeh Reservoirs. Based on the results breakout rates, frequency and mean infection density were 18.44%, 13.88% and 1.4% respectively. Maximum number of parasites in a sample was 4 and the largest parasites observed were 5.84 centimeters. Also it was observed that between sampling months the maximum rate of breakout was in March.
