ABSTRACT
A total of 287 specimens of fish belonging to family
Synodontidae (2 spp.) caught from the Mediterranean Sea
shores of Alexandria were examined for larval nematodes.
90.6 X of the examined fishes were heavily infected with
ascaridoid larvae. Parasites were removed and identifi~
as Thynnascaris larvae. Four types were described accordi~
to their morphology. Type I and type 2 were pre’;l.m8bly
identified as third stage larvae. Type 3 represented a late
third or early fourth stage larva while type 4 was most
probably fourth stage larva or preadult.
This is the first report of these nematode larvae from
fishes of the family Synotontidae from Egypt.
