Research summary
تتناول هذه الدراسة لأول مرة تحديد أوقات التكاثر ومراحل تطور المبايض والخصى لمحار اللؤلؤ Pinctada radiata في المياه الإقليمية السورية. تم تنفيذ البحث على مدى عام كامل، حيث تم جمع 380 فرداً من المحار، منهم 158 ذكراً و150 أنثى و72 فرداً غير محددي الجنس. حددت الدراسة خمس مراحل لتطور المناسل وهي: السكون، التطور، النضج، الوضع الجزئي، والوضع الكلي. لوحظت سيطرة الإناث خلال فترة الوضع من يونيو حتى نهاية نوفمبر، بينما سيطرت الذكور في باقي أشهر العام. كما تم دراسة تأثير العوامل الهيدرولوجية مثل درجة الحرارة والملوحة على النضج الجنسي للمحار. أظهرت النتائج أن ارتفاع درجة الحرارة يعد محفزاً لبدء النضج وتشكّل الأعراس، بينما تؤثر الملوحة على عملية الترشيح ونقل الجزيئات الغذائية واستهلاك الأوكسجين. توصي الدراسة بإجراء أبحاث إضافية حول خصائص بيولوجية أخرى للمحار وتشجيع تربية الأحياء المائية لتحسين الأمن الغذائي وخلق فرص عمل جديدة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في فهم بيولوجيا التكاثر لمحار اللؤلؤ Pinctada radiata في المياه الإقليمية السورية، مما يساهم في تعزيز الجهود المستقبلية لتربية واستزراع هذا النوع من المحار. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق البحث ليشمل مناطق جغرافية أخرى لمقارنة النتائج. كما يمكن استخدام تقنيات حديثة مثل التحليل الجيني للحصول على فهم أعمق لتطور المناسل. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر شمولاً إذا تضمنت تحليلاً اقتصادياً لتربية المحار وتأثيرها على المجتمعات المحلية. بشكل عام، تعتبر الدراسة قيمة ولكنها تحتاج إلى مزيد من التوسع والتعمق في بعض الجوانب.
Questions related to the research
-
ما هي المراحل الخمس لتطور المناسل عند محار اللؤلؤ Pinctada radiata؟
المراحل الخمس هي: السكون، التطور، النضج، الوضع الجزئي، والوضع الكلي.
-
ما هي الفترة الزمنية التي تسيطر فيها الإناث على عملية الوضع؟
تسيطر الإناث على عملية الوضع من شهر يونيو حتى نهاية شهر نوفمبر، مع ذروتين في شهري أغسطس وسبتمبر.
-
كيف تؤثر درجة الحرارة والملوحة على نضج المناسل عند محار اللؤلؤ؟
ارتفاع درجة الحرارة يعد محفزاً لبدء النضج وتشكّل الأعراس، بينما تؤثر الملوحة على عملية الترشيح ونقل الجزيئات الغذائية واستهلاك الأوكسجين.
-
ما هي التوصيات التي قدمتها الدراسة لتحسين تربية محار اللؤلؤ؟
توصي الدراسة بإجراء أبحاث إضافية حول خصائص بيولوجية أخرى للمحار وتشجيع تربية الأحياء المائية لتحسين الأمن الغذائي وخلق فرص عمل جديدة.

The aim of study was to determine the dates of breeding and sexual maturity for
Marsupenaeus japonicus in Lattakia coast as introduce for hatching and culturing it.
The specimens were collected from the sea water of Ibn-Hany area at the north of
L
attakia, during the period November 2010 to October 2011 once or twice monthly. In
vitro study included distinguishes males and females, morphometric measurements and
weights for all individuals. The genital maturity stage was determined externally and
through histological sections.
This study has been done on Sparus aurata (Sparidae). Fish samples (297
individuals) were collected along the Syrian Coast from March 2012 to February 2014.
Total length (T) was 15 - 31 cm, and the total weight (W) was 53,1 - 410,34 g. The study
o
f gonado somatic index (GSI) showed that the reproduction period was between
November and February with a maturity peak in January (3.98±0.97)% for females ,and in
December (2.19±0.29)% for males. In addition, the length at the first sexual maturity was
(21.5 cm) and (22.5 cm) for males and females respectively. The results of the hepato
somatic index (HSI) was compatible with the surrounding environmental and physiological
changes which resulted from the change of sexual activity during the reproductive cycle.
Fecundity showed a wide range for a given length, there was a linear relationship between
the absolute fecundity and each of length groups and total weight. Relative fecundity was
(567896-849362) egg per 1kg body weight. The frequency distribution of eggs diameters
revealed the presence of one peak, and the eggs diameter during the reproduction period
ranged from 0.05 to 0.3mm.
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 has been carried out on Saddled bream , from the
family of Sparidae, which was caught from the coastal waters of
Tartous province.
The results showed that, Saddled bream reached at the fifth stage
of sexual maturity during April and May for males and females,
and the study of the sexual maturity index GSI confirmed these
results.
Biological characteristics and life table parameters of the two-spotted spider mite Tetranychus urticae (Koch) were studied when fed on leaves of two apple cultivars (i.e. Golden and Starking dilishz) under laboratory conditions 25±1 Cº, relative hum
idity 65±5% and 16L:8D. The intrinsic rate of increase (rm) by females of T.urticae was higher on leaves of Starking dilishz apple cultivar than on leaves of Golden dilishz apple cultivar (0.30, 0.27 female/female/day) respectively, while the generation time (T) and the time required for doubling the number of community mite (DT) were lower on leaves of Starking dilishz apple cultivars than on leaves of Golden dilishz apple cultivars (13.77, 2.3 days and 14.54, 2.55 days) respectively. The duration of the stages of growth from egg to adult female on leaves of Golden dilishz apple cultivar was longer than on Starking dilishz apple cultivars, where was (13.32 ± 1.15 and 12.22 ± 1.13), respectively, The Total fecundity on Golden dilishz apple cultivar was lower than on Starking dilishz cultivar (83.11 ± 8.91, 101.62 ± 15.48 eggs/female) respectively, The adult longevity on Golden dilishz leaves was lower than on Starking dilishz cultivar (15.33 ± 1.35, 17.14 ± 1.07 days) respectively, These differences on the apple varieties may be due to the chemical content and quality of the food and nature of the host tissue plant and the specifications can affect the rate of oviposition and development. and thus the Starking dilishz apple cultivars was more suitable for the development and reproduction of T. urticae compared with the Golden dilishz apple cultivar.
