| The aim of this work was to investigate the effects of daily prey concentration during the first 15 days of active feeding of Hoplias lacerdae larvae, and the juvenile size on the feed training. In the first phase, the larvae received five Artemia nauplii concentrations (P). In the second phase, the juveniles from each treatment were trained to accept formulated diet. Superior growth was related to higher initial daily prey concentrations (900 and 1100 nauplii larvae-1). During feed training, the growth tendency was similar to that verified in the first phase. The lowest values of specific growth rate (SGR) were registered after the introduction of the semi-moist diet used in the feed training. However, the values of SGR recovered along the experiment and... |

| To evaluate the effect of two bacterial strains isolated from Artemia cysts and yeast (Candida utilis) on the survival, growth and total biomass production of its larvae, challenge tests were performed with Candida utilis, Pseudomonas stutzeri and Pasteurella haemolityca. In addition, a pathogenic strain of Vibrio alginolyticus was tested for comparative purposes. Pseudomonas stutzeri and Candida utilis have no impact on survival, but enhance growth and total biomass production of the larvae. However, we noted that Pasteurella haemolityca affect negatively Artemia larvae. The adhesion and antagonism assay demonstrates that Candida utilis and Pseudomonas stutzeri are fairly adherent and play an important role in the enhancement of the protection of Artemia... |

| ABSTRACT Previous researches have established that the swim speed of some microcrustaceans is influenced by chemical compounds emitted by conspecifics. We examined the hypothesis that cuticular compounds present on the body surface of A. franciscana, the most widespread member of Artemia genus, play a role in the swim speed of conspecific males. The movements (swim) of one male confronted to a sponge soaked with female or male cuticular extract, were recorded during 30 minutes and the swim speed was determined using a behavioral tracking software (Ethovision 3.1, Noldus Technologies). As a control, the movements of one male confronted to a sponge soaked with salty water or with a mixture of the solvents used in the extraction (chloroform-methanol), was... |

| Trials on the seabass weaning in atlantic marshes (Roux, 1993), have shown that the use of frozen prey improved this step and reduced his resulting stress. During the present study, which must confirmed these preliminary results, three alimentary sequences were tested. 1) natural zooplankton, weaning pellets, as control, 2) natural zooplankton, inert artemia (intensively produced), weaning pellets, 3) natural zooplankton, natural frozen zooplankton (harvested), weaning pellets. The achieved results show that weaning with intermediary phases (sequences 2 or 3) yield best results. Furthermore the phase with artemia yields, systematically, better results than with harvested zooplankton ; then artemia seems a excellent substitute food representing a... |

| Until recently, it was considered impossible to feed newly hatched marine fish species with a compound diet. Substituting a compound diet for live prey was performed several weeks after hatching, depending on the species. Compound diets were well ingested at the early stage but larvae died with a gut full of food, suggesting that larvae were unable to digest the compound diet. The hypothesis was that younger larvae have insufficient digestive enzymes to thrive on compound diets, and that exogenous enzymes, provided from live prey, are necessary for early stages. The organogenesis of marine fish larvae is not completely achieved at hatching and histological studies have revealed that the anatomy of the digestive tract undergoes developmental changes over... |

| Lactic acid bacteria (LAB) were isolated from rotifer cultures in a marine hatchery to search for potential probiotics for marine animals. Fifteen strains were first selected among a total of 55, according to antibacterial activity against Vibrio sp. Among eight strains identified as Lactobacillus casei, four were highly adhesive, suggesting some ability for surface colonization. The other strains were identified as Lactobacillus plantarum, Lactobacillus dextrinicus, and Leuconostoc sp. To validate probiotic potential, Artemia were challenged against pathogenic Vibrio alginolyticus, with or without one of six selected LAB strains. The six strains protected Artemia against the pathogen, to some extent on condition that nutrient enrichment was provided. La.... |

| Heat shocks at 40 degree were delivered to Artemia at the end of embryonic development and at the beginning of postembryonic development and their effects on subsequent development examined. Heat shocks delivered during preemergence development have no effect on subsequent development. Heat shocks delivered to newly hatched nauplii induce anomalies on the morphogenesis of thoracic and genital appendages. The induction of morphological anomalies by thermal conditions prevailing during early larval life makes it easier to integrate the morphological effects previously induced by nutritional conditions imposed to older feeding stages. |

| Formaldehyde was used to disinfect Artemia cysts and nauplii, while introducing two probiotics in the enrichment process: Bactocell (Pediococcus acidilactici) and Levucell (Saccharomyces cerevisiae). The disinfectant was selected due to its potential compatibility with probiotics, since it was more effective against Gram-negative bacteria than against lactic acid bacteria and yeast. However, the presence of formaldehyde reduced the intake of P. acidilactici in Artemia. Consequently, the disinfection was stopped before Bactocell supplementation to the nauplii fed to pollack (Pollachius pollachius) larvae. The mean weight of pollack was higher with this probiotic treatment. Growth was even better with the combination of Levucell and Bactocell, but the yeast... |

| Le branchiopode Artemia représente le principal organisme vivant colonisant les biotopes hypersalés. L’étude taxonomique de l’Artemia au niveau de la région ouest méditerranéenne, incluant l’Italie, la France, l’Espagne, le Portugal et le Maroc, a révélé la présence de l’espèce Artemia franciscana (qui a pour origine le continent Américain) comme étant une espèce invasive. Dans ce travail, une nouvelle population d’Artemia a été rapportée pour la première fois au niveau de Sabkhet Halk El Manzel. Une première identification taxonomique de cette population a été réalisée moyennant une étude morphologique et comparative de la forme de l’ovisac des femelles avec cinq autres populations tunisiennes appartenant à l’espèce Artemia salina et avec l’espèce... |

| RESUME La saline de Sfax constitue un site potentiel pour l’exploitation et la production de l’Artemia locale. Des quantités importantes d’Artemia sont exploitées chaque année (60 kg de cystes poids sec) et sont utilisées en alimentation larvaire. Afin de démontrer l’impact de divers rejets industriels, agricoles dans cette saline, nous avons procédé à la détermination de quelques métaux traces toxiques : le mercure (Hg), le cadmium (Cd), le plomb (Pb), le cuivre (Cu) et le zinc (Zn) par une analyse en spectrophotométrie d’absorption atomique, ce qui nous permettra d’évaluer le degré de contamination par ces métaux dans les cystes et la biomasse d’Artemia. Les résultats obtenus ont montré que les concentrations aussi bien au niveau des cystes que de la... |

| Although standardization of toxicity tests on aquatic organisms is an urgent necessity, very little has yet been achieved for the marine environment. As a first step in this direction, a simple, inexpensive and reliable short-term routine test with <i>Artemia</i> larvae is proposed. This test is the result of an extensive study in our laboratory, taking into account the advantages and disadvantages of <i>Artemia</i> bioassays published by various authors. The major advantage of the brine shrimp as a test species is its continuous availability under the form of dry cysts which can be hatched very easily; this eliminates all biological, technological, and financial problems of stock recruitment and/or culturing. The acute test... |

| The first written record of the existence of the brine shrimp only dates back to 1755 (Schlosser in Kuenen and Baas-Becking, 1938). Nonetheless this "filtering animal" was already known since much longer times by different ethnic groups who attributed a better salt production in the brine pools to the presence of <i>Artemia</i> ; hence its popular names such as brineworm, Salztierchen, verme de sale, sóféreg, Bahar el dud, Fezzanwurm, etc. Despite the primitive optical equipment available at that time Schlosser's drawings were very detailed and rightly give the adult animal 11 pairs of thoracopods. Several other scientists, including Linnaeus (1758), later described adult <i>Artemia</i> with only 10 thoracopods. This controversy... |

| This paper reports on enrichment techniques oriented towards a specific DHA accumulation in the live prey <i>Brachionus plicatilis</i> and <i>Artemia sp.</i> The product used in these experiments (DHA7) is an experimental emulsion with a DHA/EPA ratio 6.7:1. Rotifers enriched with this pure DHA7 emulsion contained up to 69 mg/g DW DHA and a DHA/EPA ratio of 1.6. The DHA/EPA ration could be increased to a much higher level by different enrichment techniques. Dilution of the DHA7 emulsion with coconut oil prior to enrichment also had a beneficial effect on the DHA/EPA ratio of the rotifers. Using a mixture DHA7/coconut oil 3:7 the DHA/EPA ratio could be raised to 4.9. In <i>Artemia</i> DHA levels were slightly influenced... |

| An updated list of more than 350 <i>Artemia</i> sites is provided. It includes geographical coordinates of the sites and available data on the mode of reproduction of the locally occurring brine shrimp.The geographical distribution of <i>Artemia</i> is related to different types of climate. The classification of climate according to Thornthwaite provides a good correlation with the geographical occurrence of <i>Artemia</i> , as a result of which the world distribution pattern of <i>Artemia</i> can be predicted. Moreover, areas with possible <i>Artemia</i> sites and areas suited for transplantation and/or inoculation with <i>Artemia</i> can be identified on the basis of water balance... |
