The alien invasive Gambusia affinis is one of the most widely introduced fish species on the planet, and has established in freshwater ecosystems across South Africa. The invasion ecology and, in particular, the population dynamics of the species in this country are, however, poorly understood. In this study the relative abundance and population dynamics of G. affinis were quantified in 5 inter...
به منظور مطالعه فیلوژنتیکی میگوهای خانواده penaeidae سواحل بحرکان، از روش تعیین توالی ژن 16s rrna استفاده شد. استخراج dna از عضله پای شنای میگوها با روش ctab انجام شد. قطعه ژنی 16srrna با استفاده از آغازگرهای جهانی 16sar/16sbr تکثیر گردید. گرچه بعد از نمونه برداری میگوی metapenaeus sp. به عنوان گونه m. affinis، شناسایی و جداسازی شد ولی blast نتایج حاصل از تعیین توالی ژن 16s rrna نشان داد که توا...
Background and Objectives: Algae are important sources of antioxidants due to their phenolic compounds, carotenoids and tocopherols. In this study, effects of the hydroalcoholic extract from Sargassum angustifolium on the shelf-life of Metapenaeus affinis were investigated. Materials & Methods: Samples were immersed for 60 min in concentrations of 100, 300, 600 and 900 mg/L of the hydroalcoho...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
This study was carried out to detect the concentration of heavy metals (Ni, V, Cu, Pb) in the muscle, gills and hepatopancreas tissues of female and male of Metapenaeus affinis in Bahrekan Bay. Sampling was conducted in 15 stations in triplicate, on which the samples collected by Trawl net. After separation of tissues, samples were digested by acid digestion with nitric and percloric acid and h...
Predation by adults of the amphipod Monoporeia affinis on the plantigrade postlarval stage of the bivalve Macoma balthica was studied in the laboratory. We confirmed that M. affinis consumes small M. balthica. Amphipods offered 14C-labelled postlarvae took up the radioactive tracer, while those presented Rhodamine B-stained postlarvae acquired gut contents fluorescing strongly in orange, wherea...
Helminth parasites of mosquitofish (Gambusia affinis) were surveyed in Bayou Traverse, a waterway in the LaBranche wetlands of southeastern Louisiana, U.S.A. In total, 1,255 parasites belonging to 8 species were collected and identified, including Ascocotyle ampullacea, Ascocotyle mcintoshi, Ascocotyle tenuicollis, Phagicola diminuta, Phagicola sp., Echinochasmus swartzi, Posthodiplostomum mini...
Collections of 'Echinorhynchus salmonis' from Britain and Ireland deposited in The Natural History Museum, London (1921.7.19.3-12 and 1952.10.30.122-127) were re-identified as Acanthocephalus clavula and Acanthocephalus lucii respectively. The amphipod, Pontoporeia affinis, European intermediate host of E. salmonis, does not occur in the British Isles, so it is concluded that E. salmonis is abs...
