Abstract
During the period between April 2008 to March 2009,144 fish from Al-Shinafya river were collected and examined . the result revealed that both kinds of fish were infected with four groups of parasites:Philometra intestinalis,Contracaecum sp,Neoechinorychos rutili and Lernaea cyprinacea . The last one was found on the skin of Cyprnus carpio .
Liza abu was infected with parasites for about 47.5% in comparison toCyrnus carpio which was %43.7 throughout the period of study . It was noticed that the highest degree of infection with N .rutili during July was 66.6% as far as Liza abu was concerned. Whereas, Cyprnus carpio was infected with the same parasite nearly 50% throughout April and August. In addition,the two kinds of fish were infected with N.rutili and P. intestinalis about 20% and 25% respectively .The percentage of Cyprnus carpio ś infection with L. cyprinacea was 16.6% throughout September and November.
The present study shows that the longer the fish is the more infected with parasites. As such, the male of Liza abu whose length was (1.15-17 cm) registered the highest degree of infection as opposed to the female of Cyprnus which was 66-6% due to its length (1.19 cm and more) .
The statistic analyses revealed that there was no abstract infection between the two sexes . And that the percentage of infection with parasites increases with the increase of temperature which was 53.8% during July.
