Ascorbic acid (Vitamin C) and folic B9) are essential micronutrients involved in hematopoiesis, immune function, antioxidant defense. enhances iron absorption red blood cell (RBC) production, while is crucial for DNA synthesis erythropoiesis. Deficiencies these vitamins associated with anemia impaired responses. This study investigates the effects of ascorbic acid, their combination on hematological parameters male rabbits, focusing hemoglobin (Hb), RBC count, white (WBC) platelets (PLAT),...
Marine gastropods are known to accumulate high metal concentrations in their tissues especially the digestive glands.In this study, accumulation of Cu, Zn, Cd, Cr and Pb gastropod Gibbula sp.(Family: Trochidae) has been assessed using Atomic absorption, spectrophotometry graphite Furnace.Animals were collected from rocky shores at Al-Hanyaa region on north-east coast Libya.Two groups animals studied; one an area adjacent a sewage outlet second was relatively clean site.Concentrations metals...
A total of 207 specimens Epinephelus guaza (Family: Serranidae) were collected from Catches by long line and spear fishing operating on Susa Coast the Mediterranean sea , Libya studied monthly April 2010 to March 2011. hepatosomatic index (HSI), condition factor (K) length-weight relationship (LWR) evaluated. Monthly variations GSI in both sexes showed higher values during period June September when HSI lower. Based HSI, reproductive cycle E. is designated into prespawning (April–May),...
Age, mortality rate (fishing and natural mortality), exploitation rate, survivor Yield per recruit for the species Liza ramada were established in Benghazi coast eastern of Libya.four age groups determined, Von Bertalanffy growth equation all individuals estimated at 35.4 cm, 0.187 year, -1.14 years 2.4 L∞, k t 0 ,respectively.Total from linearized catch curve was equal = 0.4 coefficient "M" fishing "F" 0.2 year respectively.The "E" 0.5 survival "Z" 0.7.Yield obtained 46.8 gm maximum yield 50.1 year.
Age and growth characteristics of the thin-lipped Grey Mullet (Liza ramada) were investigated in Eastern coast Libya. Aging was done by two methods: counting annuli on scales length frequency distribution, a total 218 studied for age determination, addition 334 fishes specimen distribution reading. Four groups determined from scale reading, five methods, parameters Von Bertalanffy equation both sex all individuals estimated at 35.4 cm, 0.187 per year, -1.14 years 2.4, male 35.7 0.17 -1.367...
Effects of heavy metals [copper (Cu), zinc (Zn), chromium (Cr), nickel (Ni), manganese (Mn), iron (Fe), Aluminum (Al), cadmium (Cd), mercury (Hg), stannum (Sn), and lead (Pb)] present in Tubruk harbor (polluted site) comparing to Umm Hufayan lagoon water (control) on liver kidney performance Mugil cephalus captured from both sites were investigated. For this purpose, surface samples chosen compared terms concentrations, pH, dissolved oxygen. Mullet fish blood taken the sent lab for function...
Forty-four specimens of the common torpedo (Torpedo torpedo) were collected from discarded catch long-line boat’s haul Sidi Sha’ab harbor Tripoli (May 2016) and used for establishing biodiversity morphometric traits fish. The ranged in size 13.3 to 68.2 cm total weight 92.61 989.25 g. results revealed that value constant b length-weight relationship was 1.9064 indicated negative allometric growth (b< 3). condition factors Kf Kc decreased progressively 2.54 1.82 smallest fish group (17.2 cm)...
Skeletons of five elasmobranches specimens: [Galeorhinus galeus, Squalus acanthias, Rhinobatus rhinobatus, Raja clavata, and Taeniura grabata] were collected from Susah Dernah coasts between March April 2019, scanned by XRF with Bruker S2 Ranger 2008, to study the bio-mineralization in their skeletons. Calcium carbonates CaCO3 ranged 46.53% Tope Shark 50.69% Dogfish. G. galeus peaked at its CaO (71.11%), compared nadir value T. grabata (69.03%), same species had a significant SO3 (16.2%),...
The present study aimed to establish spatiotemporal food and feeding habits of the crab Pachygrapsus marmoratus inhabiting rocky shores southern Mediterranean Sea coast, exemplified by Al-Haniyah, Al-Hamamah, Susah sites in eastern Libya, relate them morphometric traits, abundance organisms habitat. A total 425 crabs collected during 2019 were used study. minimum maxim carapace length (CL), weight (TW) were: 8.5-35.1mm, 0.4-31.0g order, means 26.79mm 12.37g. P. is an omnivore facultative...
The aim of this work was to establish morphological traits P. marmoratus inhabiting the rocky intertidal zone southern Mediterranean Sea coast. 457 collected randomly from AL-Haniyah, Al-Hamamah, and Susah sites, eastern Libya, during 2019 were used in study. largest carapace length (CL) weight (WW) 35.1cm 31.0g, respectively, while minimums 8.50cm 0.40g. means 24.5cm 10.2g. order WW by season was: winter spring > fall summer; site: Al-Haniyah Al-Hamamah; males being heavier than females....
During the winter and summer of 2019, eight study sites in eastern Libya were used to establish meiofauna diversity Southern Mediterranean Sea's near-shore sandy bottom surf region. The physicochemical characteristics surface water at mostly similar. Seventeen taxa floatable (extracted from sediment samples by floatation) identified, sixteen during ten summer: By number individuals per taxon, Nematoda Foraminifera most abundant taxa. other available Rhabdocoela, Xanacoelomorpha,...
Eighteen Sarpa salpa and fifteen Dentex gibbous fish collected randomly from the artisanal catch of Benghazi landing site, eastern Libya (32°36' N 20°03' E), during fall winter 2019 were used in present study. Morphogenic features, 21 key morphometric 6 meristic parameters established for each fish. S. was fusiform with a terminal mouth, narrow caudal peduncle bifurcate fin. The body silvery white at belly side, grading into black dorsal horizontal yellow to stripes extended head region...
Sixty sexually mature, 15- to 22-week-old, male and female laboratory-bred Swiss albinos weighing 21 43g each were used in the present study find out effect of exposing mice 35 40C0 for 4 hours on their blood parameters using Complete Blood Counts (CBC) as indicators. The experimental design was groups 2 X factorial arrangements genders heat treatments. were: 30 per treatment. treatments Control: (15 males 15 females) kept four at room temperature (25 ± C0), stress: 40 0C ambient hours....
