| In order to prevent any further confusion in the scientific literature, we would like to urge contributors to ensure that the citation of <i>Artemia</i> in scientific articles in <i>Aquaculture Research</i> is taxonomically correct. Too frequently, reference is made to <i>Artemia salina</i>. This binomial refers to a European species which may be extinct. Most scientific studies are, however, based on the New World species <i>Artemia franciscana</i>. We estimate that over 90% of the studies in which <i>Artemia</i> is used as experimental test organism or as food source deal with this particular species, very often using material from the Great Salt Lake in Utah, USA. Today at least six bisexual... |

| An <i>Artemia</i> population from a site recently described in Chile and located in a semi-arid and humid hydrographical zone (Torres del Paine National Park), was electrophoretically characterized and cross-bred (followed through <i>F</i><sub>3</sub>) to reference samples of <i>A. franciscana</i> (San Francisco Bay, California, USA) and <i>A. persimilis</i> (Buenos Aires, Argentina), which are the species most likely to be found in Chile. The population exhibited high levels of genetic variability as judged by the percentage of polymorphic loci (<i>P</i>=53.3), mean number of alleles per locus (<i>n</i>=2.2) and mean heterozygosity (<i>H</i>=0.176). Based on... |

| A scanning electron microscopy (SEM) study of bisexual <i>Artemia</i> populations revealed that populations representing the species <i>A. franciscana, A. persimilis, A. urmiana, A. sinica</i> and a recently described species from Kazakhstan have a pair of spine-like outgrowths at the basal parts of their penes, whereas populations from Southern Europe and North Africa (i.e. Mediterranean populations) lack these spine-like outgrowths. Allozyme and DNA polymorphisms, detected by allozyme starch gel electrophoresis and AFLP fingerprinting, respectively, suggested conspecificity of the studied populations from the broader Mediterranean basin. Male specimens from the collection of the Natural History Museum of London (UK) of the extinct... |

| We present evidence that incubation of brine shrimp <i>Artemia</i> encysted embryos (cysts) at high temperatures (36-37°C) suppresses hatching of cysts from a parthenogenetic population, while at the same time allowing cysts of the New World bisexual species (<i>A. fransiscana</i>) to hatch. This approach is used to verify the presence of contaminating foreign material from the New World in natural cyst populations of Old World <i>A. parthenogenetica, A. sinica, A. urmiana</i> and <i>A. tunisiana</i>. We demonstrate that high temperature incubation can be routinely applied to cysts from natural <i>Artemia</i> populations occurring adjacent to fish and shrimp hatcheries, to determine the extent and... |

| The brine shrimp <i>Artemia</i> , a typical inhabitant of hypersaline environments and characterized by a highly subdivided population structure, was used as a model to evaluate, under standardized laboratory conditions (at 65 ppt), primary reproductive traits (offspring quality and quantity) along with levels of reproductive isolation and degrees of divergence among populations. Intrapopulation experimental crosses and cross-fertility tests were evaluated in five populations (mostly <i>A. franciscana</i>) from coastal and inland environments in Chile, and in reference samples of <i>A. franciscana</i> (San Francisco Bay, USA) and <i>A. persimilis</i> (Buenos Aires, Argentina), which are the species likely to... |

| Marine aquaculture, particularly the salmon farming industry, has expanded very fast in Chile. Currently the country ranks second among the world leading salmon producers. However, there is a growing concern for the diversification of aquaculture activities. Examples are the cultures of flatfishes, either the introduced turbot (<i>Scophthalmus maximus</i>) or the native flounder species <i>Paralichthys microps</i> and <i>P. adspersus</i>, along with the native scallop, <i>Argopecten purpuratus</i>. Although both turbot and scallop farming have had a successful transition from pilot to industrial scale, dependable availability of larvae/seed at cost-effective prices is, unlike the situation in the salmon... |
