The study was conducted in a fish laboratory in the college of
veterinary medicine during the period between the months of
March and September. The experiments of this study were
performed in laboratory conditions. Five dosage levels of
Ivermectin were administered.

This research was carried out during the period 08/28/2012 - 07/29/2013 in order to
determine the qualitative composition of Puffer Fishes (Tetraodontidae) in the marine
water of Latakia.
Fish samples were collected from three stations (Borj Islam
, Al madina al riyadiah
and Jableh), the total of fishes were / 255 / individuals. All fish individuals were classified,
preserved and placed at the High Institute of Marine Research Laboratory, some biological
factors of the collected fish (K%, GSI%,HIS%) were studied.
Results had revealed the presence of five species of Puffer Fish belong to three
genera of Tetraodontidae: Lagocephalus sceleratus, L. spadiceus, L. suezensis,
Sphoeroides pachygaster, Torquigener flavimaculosus. S. pachygaster species (migratory
species from the Atlantic Ocean to the Mediterranean Sea) has been recorded for the first
time in the marine water of Syria. Results showed that L. suezensis were more coincidence
species in the catch. The amounts caught of Puffer Fishes varied according to the stations;
the highest was in Borj Islam. K% was almost similar in all species, while GSI% and
HSI% varied according to the species and seasons.

This paper aimed to present additional records of Honeycomb stingray Himantura
uarnak (Forskal, 1775) (Chondrichthyes: Dasyatidae) off the Syrian coast (Eastern
Mediterranean). Two specimens were captured in Syrian waters (Tartous coast) 35º 55’
3
1”E and 34º 42’ 40’’ N. The first specimen was an adult female, and the second an adult
male; they measured 1078 mm and 840 mm disk width, and weighed 31.450 kg and 15.580
kg, respectively. Morphometric measurements were recorded to the nearest millimeter, and
reported as percentage of the disk width (%DW). Pieces of skin and tail were deposited in
the Ichthyological collection of the Marine Sciences Laboratory, Agriculture Faculty of
Tishreen University, Syria.

A total of 30 water samples and 45 infected fish (carp, Cyprinus carpio) were
collected from freshwater fish farm (Dam of 16 Tishreen-Lattakia) and
analysed bacteriological. Macroscopic examinations of infected fish had showed
the presence of haem
orrhagic skin lesions with brown or red spots throughout
their skin. A total of 64 Aeromonas strains were isolated. The Aeromonas
isolates were distributed as follows: Aeromonas hydrophila (34, 53%), A. caviae
(16, 25%), A. sobria (9, 14%) and (5, 8%) of unidentified aeromonads.
Collectively, Aeromonas spp. are considered as opportunistic causative agents
of human gastroenteritis and other infections. Antibiotic susceptibility tests
were carried on all strains of isolated Aeromonas spp. using twenty different
antibiotics by agar disk diffusion method.
