Tebufenpyrad (TUBF) is classified as a pyrazole acaricide and insecticide extensively utilized in greenhouse environments several countries. Nevertheless, limited data exists regarding the potential reproductive toxicity of TUBF, particularly non-target species. In this study, fatty acid (FA) composition, histopathology aspects, redox status were assessed digestive gland clam Ruditapes decussatus following short-term exposure (96 h) to series concentrations (50, 100, 200 µgL-1) TUBF. Our...
Mercury (Hg) is among the most deleterious contaminant in aquatic environment and presents a serious risk to humans ecosystems. This study evaluated effects of Hg on oxidative stress biomarkers, DNA integrity histological structure respiratory tree Holothuria forskali exposed different concentrations mercury chloride HgCl2 (0.04, 0.08 0.16 mg L−1) for 96 h. Exposure H. led with an increase Malondialdehyde (MDA), hydrogen peroxide (H2O2), advanced oxidation protein product (AOPP) carbonyls...
The fatty acid composition and fat quality alteration of the round sardinella (Sardinella aurita) European hake (Merluccius merluccius) fillets during frozen storage (-30°C), sun drying controlled oven (temperature = 60°C, air velocity 2 m/s relative humidity 20%) were investigated. Results show that fresh the S. aurita and M. merluccius were particularly rich in polyunsaturated mainly Docosahexaenoic Acid (DHA) eicosapentaenoic (EPA). Changes saturated acids (SFA), monounsaturated (MUFA),...
Mercury (Hg) is a ubiquitous and major environmental metal pollutant in the aquatic ecosystem. The present study was performed to evaluate effect of mercury graded doses exposure on oxidative stress, redox status, metallothionein levels genotoxicity intestine sea cucumber Holothuria forskali. Specimens were exposed for 96 h three concentrations Hg (40, 80 160 µg/L). Exposure H. forskali promoted stress with an increase malondialdehyde (MDA), protein carbonyl (PCO) advanced oxidation products...
Abstract Previous scientific studies have listed chemical compounds from sea cucumber species. The ability to produce bioactive metabolites derives their response various ecological stresses and avoidance of predation. In view this, the present work aimed evaluate antibacterial activity quantitatively assess active components different organs Holothuria foskali collected north-east Tunisia. ethyl acetate extracts was tested against Bacillus subtilis , cereus Escherichia coli Pseudomonas...
The effects of the starvation trial on biochemical composition and fatty acid dynamics in triacylglycerol fraction digestive gland, gonads adductor muscle scallop Flexopecten glaber were assessed. Results show that three weeks food deprivation induce depletion carbohydrates a significant decrease proteins lipids. noteworthy patterns recorded for various classes lipids increase amount phosphatidylethanolamine against strong decline mono-diacylglycerols, phosphatidylserine gonads. These...
The bivalve Venerupis decussata has been proposed as a sentinel species for assessment of lagoon water. Our study aimed to evaluate the spatial and temporal variation oxidative stress biomarkers, metal content DNA damage in digestive gland collected seasonally from contaminated (BOUGHRARA “L2”) comparatively cleaner ( GHAR EL MELH “L1”) lagoons. Trace contents (Cu, Pb Cd) at polluted site were 1-2 folds higher compared control showed maximum especially during summer spring seasons. current...
This study reveals information for the first time about total lipid (TL) content and fatty acid composition (FA) of Mactra stultorum (M. corallina). Three edible organs (foot, mantle adductor muscle) were subjects this research in order to determine most favorable periods their consumption relation seasonal variability. The results showed lower muscles summer (12.73 ± 2.55 mg/g dry matter); while a higher was observed winter (28.97 3.50 matter). However, similar contents foot tissues among...
The effects of artisanal and controlled oven drying methods on the biochemical composition body wall sea cucumber, Holothuria forskali were investigated. Five combinations temperature ( ° C) relative humidity (%) levels tested (50°C, 20%, 60°C, 25%; 15%, 20% 70°C, 20%). results demonstrate that treatment (60 C 20%) yields an improvement nutritional quality initial product. Improvements particularly noted in terms amount total proteins polyunsaturated fatty acids level dry H. .
The parasite Peroderma cylindricum uses its host Sardina pilchardus to meet own needs. can have many harmful effects on host. present study aims at investigating the impact of composition fatty acids and quality lipids sardine. reduces total lipid content by about 25% decreases saturated acid polyunsaturated acid. However, it increases amount monounsaturated acids. induced a selective diversion some acids, which are dominated docosahexaenoic Consequently, lower n-3 omega-3/omega-6 ratio were...
This work aims to examine the reproductive cycle of bivalve Mactra corallina inhabiting Gulf Tunis (Tunisia). Histological analysis indicated that is composed six stages and was synchronous between sexes. Gonadal development began in January. From April July, an increase temperature (from 16 28°C) a rise chlorophyll 3.25 6.35 mg/L) marked period sexual maturity both sexes, which also confirmed by elevation condition index (CI). Partial spawning started for males May females, peaking late...
This study aimed to provide information about the changes in fatty acid composition and quality Ruditapes decussatus tissue after four culinary treatments (steamed, baked, grilled fried). All treated samples showed a significant decrease moisture protein. In contrast, increase fat content resulted from fried treatments. Saturated was significantly higher fresh clams than all cooking processes, except ones. Monounsaturated polyunsaturated varied between cooked with high values recorded for...
