Up to now research was short-term, aiming at solving practical questions connected with gamete storage and artificial insemination. More information on gamete biology is now available and has been summarized in this minireview.In vivo storage of gametes in the genital tract after ovulation or spermiation may be influenced by the osmotic environmentvia changes in the ionic composition of the companion fluid. There is great inter-individual variability in gamete survival bothin vivo andin vitro. Mechanisms involved in the initiation of trout sperm motility have been analysed; after dilution in water or NaCl solution (125 mM) at pH > 7, Ca(++) entry due to changes in membrane potential have been observed. The involvement of cAMP and protein phosphorylation has been reported. The morphological, physical and biochemical changes in eggs that have been studied after fertilization and the corticol reaction lead to a better understanding of the mechanisms of polyspermy blockage.

SmartLP, a case-based lesson planning system, has been implemented as a means of assisting teachers in constructing quality lesson plans more quickly. SmartLP enables teachers to retrieve previous lesson plans and customise them according to their constraints as they should be tailored to accommodate differences in students, teachers and the facilities available. An evaluation study was designed to examine the effectiveness of a Case Based Reasoning (CBR) approach through its cycle of retrieve, reuse, revise and retain in assisting teachers in constructing lesson plans and to assess the effects, in terms of time and quality, the system had on lesson plan preparation. This paper presents the results of the study. The study revealed that all the lesson plans constructed with SmartLP took significantly less time than lesson plans constructed without. In addition, where the planning tasks had greater similarities to the cases in the case base, they took even less time to be constructed. No significant difference in the quality of the plans, measured by a scoring system, was noticed between the control and experimental groups.

A specimen of the non-indigenous species areolate grouper Epinephelus areolatus (Forsskål, 1775) ... more A specimen of the non-indigenous species areolate grouper Epinephelus areolatus (Forsskål, 1775)
and two specimens of pilotfish Naucrates ductor (Linnaeus 1758) were fished from the coastal waters off
Latakia, Syria. The finding of E. areolatus constitutes the first substantiated record of this species for Syrian
marine waters and the third for the entire Mediterranean Sea. The areolate grouper is a Lessepsian migrant
from the Red Sea which entered the Mediterranean through the Suez Canal. N. ductor, on the other hand,
has been known to inhabit the Mediterranean Sea together with several other fish species. However, the
semi-obligate commensal relationship that it develops with large sharks and rays could explain the species’
occurrence in both the Mediterranean and Syrian marine waters. The capture of N. ductor reported herein
is the second record for the Syrian coast.

In all, 18 sets (2 female x 4 male in each set) were tried individually. 9 sets were treated with domperidone (DOM) and carp pituitary extract (CPE) and they constituted the experimental sets, while the rest 9 were treated with CPE and formed the control sets. The ovulation ratio, absolute fecundity, relative fecundity (number of eggs/kg), fertilization rate and hatching rate was 92.85%, 384645 ± 70990 eggs, 56853.22 ± 5385.68 eggs/kg, 80.02% and 61.54%, respectively in the experimental sets whereas it was 92.85%, 355172 ± 53008 eggs, 52059.73 ± 3853.71 eggs/kg, 72.50% and 54.46% respectively in case of control sets. Hatching occurred within 20 h and 45 min to 21 h after fertilization in the experimental sets whereas it was 20 h and 45min to 21...

The specimen is described with morphometric measurements, while the species occurrence in the area and the Mediterranean Sea is discussed and commented. This new finding constitutes the first record of the species for the Syrian coast, and also its easternmost extension range in the Mediterranean Sea. Additionally, sea lamprey remains an occasional visitor in the Syrian waters and, consequently, the local occurrence of a viable population remains doubtful.

Sparidae fish species in the Syrian marine waters. Fish samples were collected from catch
landing ports along the Syrian coast (Raas Al-Bassit, Lattakia, Jableh, and Tartus), which
were fished by fishermen within the Syrian territorial waters exclusively, using different
fishing methods (Traps, gill nets, trammel net, trawl, long line,fishing rod, spearfishing ..)
The samples were transferred to the laboratory of Marine Sciences and Fish Lab, Faculty
of Agriculture at Tishreen University, to take morphometric measurements and meristic
data. All species have been classified, briefly described and documented.
The results showed that 25 fish species belonging to 11 genera were found, in which two
immigrants fish species was recorded for the first time in the Syrian marine waters,
Pagellus bogaraveo as an immigrant species from the Atlantic Ocean and Pagrus major
indo-pacefic species, introducd to the Eastern Basin of Mediterranean Sea. Additionnaly 5
species recorded previously in the Syrian marine waters were not found in this study.

In this work, we document the first record of a Red Sea species (Lesbesian immigrant), Heniochus intermedius (Steindachner, 1893), in the Syrian coast, the seventh record in the entire Mediterranean. As a result, the number of fish migrating from the Red Sea to the Syrian marine waters has reached 82 species. The methods of introduction and arrival of fish of this species into the Mediterranean are also discussed.

Lack of basic knowledge, such as species composition and habitat, makes it impossible to develop effective conservation measures. The survey carried out along the Syrian coast by monitoring the stranding individuals on the shore since 2002 showed that there were 11 species of marine mammals living in/or visiting the Syrian marine waters at present of which 10 species belonging to the cetacean order and on belonging to pinnipeds order. The following species have been recorded: Pseudorca crassidens, Megaptera novaeangliae, Physeter macrocephalus, Tursiops truncatus, Stenella coeruleoalba, Delphinus delphis, Ziphius cavirostris, Grampus griseus, Balaenoptera physalus, Balaenoptera acutorostrata, and Manchus manchus.

On the other hand, there are four species whose presence in the Syrian marine waters was mentioned a century ago by the researcher Gruvel and his team during three missions (1929-1931), but neither alive nor dead have been seen in this area during the surveys that were carried out since 1996 until the present, these species are: Phocoena phocoena, Globicephalus melas, Phocoena communis, Hyperoodon rostratus, Balaenoptera musculus. These observations reflect the vulnerability of marine mammals to anthropogenic activities, such as fishing operations, shipping, seismic activities, and climate change.

It includes a length of about 10 km suitable for sea turtle nesting. The beach was divided into 7 subsections, each of them between 0.3 and 3 km long. The nesting success was 25% for the loggerhead turtle and 40% for the green turtle. A total of 106 dead marine turtles were observed, including 95 (92%) loggerhead turtles and 11 (8%) green turtles

The present specimen measured 214 mm in total length and weighed 169 g. It is the first record from the Syrian coast and the third from the eastern Mediterranean. It constitutes also the easternmost extension range of the species in this sea. P. major is a non-native species from the Mediterranean, introduced via sea farrming or released from aquariums. It is a highly adaptable to environmental changes in the wild, additionally it is an opportunistic feeder. The successfull establishment of a viable population of the species in the Mediterranean Sea cannot be totally ruled out.

One specimen was caught by trawl nets at about 300 m depth in Rass Albassit, north of Lattakia, on 25 February 2019, and 6 additional specimens were caught by gill nets at a depth of 120 m off Jablah coast on 7 April 2019. This record represents the first sighting of this immigrant Atlantic species introduced in the Eastern Mediterranean (Levantine Basin). These specimens were found mixing in the same net haul with populations other Sparidae species such as: Pagellus acarne and Dentex macrophthalmus.

All captured specimens were mature females carrying developed ovaries with yellow yolked oocytes. Additionally the use of the local ecological knowledge allows to assess the status of P. lineatus which is successfully established in the area where it is able to live and reproduce.
