Abstract Studies revealed the role of Artemia salina as intermediate host in life-cycle a cestode species parasitizing flamingos, i.e. Flamingolepis liguloides. Cysticercoids this parasite were found for first time Algerian populations winter 2000 and 2001 Chott Marouane spring 2003 Sebkha Ez-Zemoul. The prevalence ranged between 10 33% two examined populations. intensity infection was 1–3 cysticercoids per individual. abdomen most targeted site (95% population Ez-Zemoul) followed by thorax...
Nine currently accepted species of the genus Sargassum (Phaeophyceae) have been recorded from Mediterranean Sea: S. acinarium, desfontainesii, flavifolium, furcatum, hornschuchii, muticum, ramentaceum, trichocarpum and vulgare. Two them, desfontainesii are Atlantic species, range which is restricted to Alboran Sea, close Strait Gibraltar. Three ramentaceum endemic Mediterranean. The presence flavifolium in Mediterranean, a north-eastern at least part based upon misidentification therefore...
The aim of the study was to determine seasonal variations two biomarkers oxidative stress, Glutathione (GSH) and S-transferases (GSTs), in sponge Sarcotragus spinosulus Schmidt, 1862 (Porifera Irciniidae).The samples were collected during four seasons 2016-2017 at sites Gulf Annaba (northeast Algeria): Cape de Garde, which is some distance from any source pollution, considered a relatively clean site, while Alzon site exposed various sources industrial, urban harbour pollution.The results...
The objective of this study was to determine the basic population-specific parameters necessary for fish stock assessment in Gulf Annaba and compare these with data from other Mediterranean regions. Black sea bream Spondyliosoma cantharus (Linnaeus, 1758) (N = 501) were collected monthly January December 2008 along Algerian eastern coasts. More than 22 each month ranged size 13.4 40 cm total length, weighing 36 1080 g eviscerated weight. Biological sampling included measuring fish, gonad...
Abstract The diet of the greater forkbeard Phycis blennoides (Brünnich, 1768) Algerian coast was studied between December 2013 and June 2015, providing information on its ecology for a better understanding feeding strategy. A total 956 individuals, whose length (TL) varied 9.7 54.5 cm weight (W) 2.80 1334.11 g, were examined. index relative importance (%IRI), combining three main descriptors presence different ingested prey (%F, %N, %W), used to characterize food taxa. Qualitative...
The diet of the goldblotch grouper Epinephelus costae eastern coast Algeria was studied from March 2011 to February 2012. A total 275 individuals, whose length varied between 21.1 and 79.79 cm weight 103.13 5390.00 g, were examined. index relative importance (%IRI) combining three main descriptors presence different ingested prey (%F, %N, %W) used characterize food taxa. Qualitative quantitative variations in according sexual maturity (immature mature), sex (male female), size (small, medium...
Résumé. — Cette étude est consacrée à quelques aspects de l’écologie et la biologie d’Artemia salina (Branchiopode, Anostracé) sebkha Ez-Zemoul, située dans le nord-est l’Algérie (35° 53’ N -06° 30’ E). Le suivi sa structure démographique densité, entre janvier 2003 février 2005, montre que ce crustacé apparaît en novembre, suite l’éclosion des cystes, atteint une densité maximale mars (56 ind. L-1 38 2004) disparaît complètement partir juillet. La sex-ratio toujours faveur mâles ses valeurs...
Abstract Some ecological aspects of the alien crab Percnon gibbesi (H. Milne Edwards, 1853) have been approached by visual surveys in southwestern Mediterranean waters (East, Algeria). This sampling method, applied on a coastal line 16.2 km and between 0 − 3 m depth, allowed us to collect information abundances densities size category, nature habitat behavior this species. Overall 22 diurnal dives (3 observations/dive) were carried out 2 different adjacent costal sectors, Bay Annaba (Sector...
Résumé Du sperme de daurade Sparus aurata est prélevéà diffkrentes dates la saison spermiation. La composition biochimique du plasma séminal analyské. concentration des éléments dosés généralement plus importante que chez les espèces d'eau douce. teneur en protéines reste constante au cours temps. quantité glucose accuse une diminution à partir mi-décembre. Les triglycérides et le cholesterol atteignent valeurs relativement elevees aux limites période d'échantillonnage, tandis taux calcium...
