The brine shrimp Artemia, an excellent live food source in aquaculture, has been studied as a carrier to deliver selected chemotherapeutic agents to fish for prophylactic treatment of infectious diseases. To monitor the efficiency of incorporation of trimethoprim and sulfamethoxazole in Artemia franciscana, a sensitive and specific analytical method was developed. It is based on homogenization ...
این تحقیق با هدف بررسی شدت کشندگی فلز سنگین کادمیوم و تعیین lc50 و امکان تجمع زیستی آن در آرتمیای دریاچه ارومیه (artemia urmiana) در شرایط آزمایشگاهی انجام شده است. مقاومت a. urmiana در برابر فلز کادمیوم در مراحل مختلف زندگی مورد بررسی قرارگرفت. آرتمیا در تکثیر و پرورش آبزیان بسیار مورد توجه می باشد، لذا نوع پاسخ این موجود به آلاینده ها از جمله کادمیوم با توجه به آلودگی روزافزون آن، اهمیت بسیا...
Eriocheirsinensis, Portunus trituberculatus and Scylla paramamosain are important commercial culture crab species in China. Traditional factory breeding of crabs depends on Artemia nauplius. The rising price of Artemia cysts has led to the decline of the economic benefit of the crab breeding factory. Factory crab breeding has been gradually replaced by pond breeding in recent years. E. sinensis...
Decorator crab Camposcia retusa is a popular marine ornamental species; however, it has never been bred previously. To establish feeding regime for C. larvae, which include two zoeal and megalopal stage, three experiments were conducted. In all experiments, ≥60% of unfed 1st (Z1) larvae survived to the next combined with orange guts observed in fed Artemia, suggesting Z1 are facultative lecitho...
Artemia franciscana nauplii was enriched with a bacterial species Weissiella koreensis (lactic acid gram-positive) isolated from the alimentary tract of Stellate sturgeon (Acipenser stellatus), at 3 levels. Treatments included T1: 6.9×104 colony-forming units (CFU) mL-1, T2: 6.9×105 CFU mL-1, T3: 6.9×106 CFU mL-1 and their effects were compared with the control diet (no probiotic were added). E...
Artemia nauplii are the best initital food for most fish larvae. Feeder fish, nauplii, contain ingredients necessary survival of aquatic organisms during critical periods early postembryonic ontogenesis. Thus, it is important to improve biotechnology cultivation in artificial ecosystems.
 Materials and Methods. In course study, various illumination modes were used, namely, 1.5; 2.5 4 klx d...
Although there is growing evidence that metals can be toxic to various aquatic species, there is still insufficient knowledge to integrate this information in environmental risk assessment procedures. In this study, we have investigated lethal Concentration (LC50) and toxicity effects of vanadium on mortality and growth of Artemia urmiana and Artemia franciscana. The in 24 h of A. urmiana and A...
Endemic Artemia franciscana populations can be found throughout the American continent and also as an introduced specie in several country all over the world, such as in the Mediterranean region where Artemia franciscana was identified as an invasive specie replacing native Artemia parthenogenetica and Artemia salina. In the present study, the characterization of the new invasive Artemia franci...

Six different diets including two rainbow trout starters, Gammarus dry powder, shrimp dry powder, egg yolk dry powder and newly hatched Artemia were used in feeding of Caspian Kutum larvae. During a 4-week trial, larvae with a mean weight of 17.5 ± 4.7 mg were fed with three replicates and growth parameters were measured at the end of the experiment. Thirty fish in each experimental unit with...
