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 study describes the changes in species composition of phytoplankton under different
Si:N ratios from spring to summer of 2010 and 2011. For this purpose, natural
Phytoplankton was cultured in mesocosmic experiments at two stations in the north
ern part
of Latakia coastal water. The abundance of phytoplankton was measured, and the specific
composition of phytoplankton was determined. Diatoms dominated during 2010 and 2011,
while Dinoflagellates did not compete with diatoms during this study. The enrichment experiment
affected the species composition of the diatoms themselves, where the species
Pseudo-nitzschia pseudodelicatissima Schil and Leptocylindrus danicus Cleve dominated
under different Si:N ratios.
