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... |

Using cyst material produced in an indoor cyst production system from 4 <i>Artemia</i> strains belonging to the species <i>A. franciscana</i> (San Francisco Bay, California, USA; Macau, Brazil; Great Salt Lake, Utah, USA) and <i>A. parthenogenetica</i> (Lavalduc, France), different factors were studied that affect dormancy in brine shrimp cysts. Preliminary experiments under varying (a)biotic culture conditions revealed an interaction between environmental conditions and hatching characteristics. Results obtained under better-defined conditions demonstrated a significant positive correlation between the amount of food available to the adult <i>Artemia</i> populations and the hatchability of their encysted... |

The recent developments in aquaculture production of fish and shrimp have resulted in increased demands for <i>Artemia</i> cysts and biomass as valuable sources of life food. Solar salt works are suitable biotopes for the integrated exploitation of salt, <i>Artemia</i> and eventually fish or shrimp. <i>Artemia</i> may be present as a natural resource in local saltworks; however in some situations characteristics of the endemic strain might justify the introduction of another <i>Artemia</i> species to increase productivity. |

A fluidized bed dryer for processing <i>Artemia</i> cysts at the temperatures above 40°C is described and evaluated. The design is directed towards electronic temperature regulation and optimal design of the drying unit. The described fluidized bed dryer proves to be reliable for cyst processing, using inflow air temperatures up to 90°C. The use of this elevated temperature ensures a higher drying rate, resulting in a drying capacity more than 4 times higher than when using inflow air of 40°C. Electronic temperature regulation resulted in a large flexibility of the temperature regime inside the drying unit. |

<i>Artemia</i> production in NE-Brazil began in 1977 after a successful inoculation of <i>Artemia franciscana</i> (San Fransisco Bay, California, USA) in solar salt ponds in Macau (RN state) and was followed by a rapid natural dispersion of this crustacean to all saltwork areas in the region. <i>Artemia</i> is basically produced in extensive conditions as an opportunistic by-product collected from salt evaporation ponds. This type of approach has, however, brought about very unpredictable results, as is reflected in a drastic decline of cyst production occurring from 1982 onwards. Low nutrient concentrations and a drop in primary productivity have been suggested as possible causes for this decline. In order to provide a... |

Although dietary phospholipids (PL) and particularly phosphatidylcholine (PC) have been found to enhance growth and survival in penaeid shrimp, precise requirements have yet to be established. Substantially variable responses of feeding PL have been noticed in crustaceans in relation to the growth stage of the animals and the composition of the other dietary ingredients. In several shrimp feeding trials phospholipids of unspecified composition, have been used, such as crude lecithin, as a result of which it is difficult to draw conclusions with regard to the optimal levels/types of dietary PL required by penaeid shrimp. This paper is part of a broad study which aims to assess the dietary effect of different levels/types of purified PL in marine fish and... |

African catfish (<i>Clarias gariepinus</i>) larvae were fed on five preparations of decapsulated Great Salt Lake <i>Artemia</i> cysts: 1) dried (35°C, 6 h) and UV-irradiated cysts; 2) heated cysts (80°C, 10 min); 3) brine dehydrated and UV irradiated cysts; 4) micro-bound diet 1(with intact decapsulated cysts used in diet preparation 1); and 5) micro-bound diet 2 (with crushed and shifted decapsulated diet used in diet preparation 1). The larvae were fed from the first day after yolk-sac resorption (fourth day after hatching). After a 14-d rearing period, larvae fed on dried or heated decapsulated cysts or micro-bound diet 1. Feeding micro-bound diet 2 resulted in a significantly lower average gain in weight as compared to the other... |

Among the live diets used in the larviculture of fish and shellfish, the brine shrimp <i>Artemia</i> nauplii constitute the most widely used food item; i.e., over 700 metric tons of dry <i>Artemia</i> cysts are annually marketed worldwide for on-site hatching into 0.4 mm nauplii.Although the use of <i>Artemia</i> appears to be simple, considerable progress has been made in the past decade in improving and increasing its value as a larval diet for marine fish larvae. The improvements include: identification of the most appropriate strains and batches; new techniques for cyst disinfection; decapsulation and hatching; and enrichment and cold storage of nauplii. Using particulate or emulsified products rich in highly... |

A standard method has been developed to produce F<sub>1</sub>-generation cysts from different zygogenetic strains and their cross-breeds. The F<sub>1</sub> cysts were used to determine the quantitative heritability of the following characteristics: cyst hatchability, cyst diameter, larval growth, and temperature resistance of the freshly-hatched nauplii.Data are given for cysts produced from nine strains and seven cross-breeds. Important differences for all characteristics studied were noted between the cross-bred and the parental strains. |

In recent years, there has been a growing awareness of the hydrobiological aspects of the solar salt production process. Saltworks are man-managed artificial ecosystems that are highly vulnerable to biological disturbances, including uncontrolled proliferation of microalgae resulting in a reduced evaporation and contamination of the salt with gypsum and insoluble organic materials.Optimal production of solar salt, both in terms of quality and quantity, requires a well-established balance between the primary and secondary producers, with brine shrimp <i>Artemia</i> grazing on phytoplankton constituting the major interaction. In this paper, we discuss the beneficial role of <i>Artemia</i> in balancing the hydrobiological activity of... |

The worldwide distribution of the brine shrimp <i>Artemia</i> , in a variety of isolated biotopes with different ecological conditions, has resulted in the evolution of many geographical strains. Among these strains, substantial differences have been demonstrated in their nutritional quality and fitness, providing a basis for the selection of strains suitable for aquaculture. The Tanggu Saltworks (Tianjin, China) provide a unique environment for the production of <i>Artemia</i> . Unlike most other biotopes, they are characterized by a high primary productivity providing abundant food to sustain large populations of <i>Artemia</i> . Both laboratory studies and field observations, however, indicate that the local... |
