Biometrical, biochemical and food-value characteristics of <i>Artemia</i> nauplii vary with the source of the cyst material. In order to facilitate intercalibration and/or comparison of research conducted with cysts from different sources, homogenous cyst material can now be obtained from the <i>Artemia</i> Reference Center (State University of Ghent, J. Plateaustraat 22, B-9000 Ghent, Belgium). The reference cysts have been tested extensively for hatching characteristics, biometrics, fatty-acid content, pesticide contamination and effectiveness as larval food for various crustaceans and fishes. |

During the expeditions Cimar - Fiordos 2, 3 and 4 (1996, 1997 and 1999), samples of marine sediments were collected in Southern Chile, between Melinka (Lat. 43° 45' S) and Beagle Channel (Lat. 54° 56' S) to study the distribution and abundance of dinoflagellate cysts, particularly the toxic dinoflagellate Alexandriurn catenella. Samples were collected from 33 stations at depths of 1 to 15 meters. The study included photographic record and taxonomic identification of cysts to genus and, whenever possible, to species, with emphasis on the identification of cysts of A. catenella. Cysts from samples collected in cruises 3 and 4, were incubated in f/2-Se culture medium at 13 °C with controlled photoperiod (14:10, L:D), to induce germination and confirm species... |

Santiago de Cuba bay is an ecosystem eutrophic and vulnerable to FANs events. This work preset the results of monitoring during three year in eight stations located in the less polluted area of the bay, leading to the determination of the possible seasonal distribution and FANs frequency. 117 Phytoplankton species were identifying, which belong to 5 divisions; 28% of these species are reported as potentially toxic and/ or noxious. This zone of the bay classifies as politrophic, heterogeneous and dynamics. It highlights the cysts presence, as well as the occurrence of unialgal "blooms" of Gymnodinium catenatum and Cochlodinium polykrikoides, indicating the presence in the ecosystem of favorable conditions to HABs occurrence with negative impact on the... |

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. |

As described in our previous paper (Sorgeloos et al. , 1977) hypochlorite can be used as reactive agent to dissolve the lipoproteic chorion of <i>Artemia</i> cysts. Two commercial products are available worldwide, i.e. bleaching powder, chloride of lime Ca(OCL)<sub>2</sub> and bleaching water NaOCl solutions. In Western Europe the latter product is the cheapest, whereas in the USA and Southeast Asia bleaching powder should be considered. Because the decapsulation process is a much more critical operation with bleaching powder, especially with regard to the viability of the embryos (Bruggeman et al., in preparation; Manzi, personal communication), we studied the use of technical NaOCl solutions in detail. |

In this study, one-cycle and multi-cycle culture systems for <i>Artemia</i> in seasonal salt ponds are compared. In one-cycle systems, <i>Artemia</i> is inoculated only once per season, while in multi-cycle systems ponds are drained and re-stocked several times per season. In Vietnam, three-cycle systems gave significantly higher cyst yields than did the one-cycle system. However, after two cycles, systems were not significantly different. Food limitation probably caused the steady decline in cyst yields, as observed in the one-cycle ponds. In these ponds, females have smaller broods (from the second cycle onwards) and during the last cycle the number of adult females is lower than in multi-cycle ponds. |

Variations in dry weight, caloric content and ash content during cyst hatching and early larval development have been studied for various geographical strains of <i>Artemia</i> . In general, decapsulated cysts contain 30 to 40% more energy than freshly hatched nauplii; for Chaplin Lake and Buenos Aires <i>Artemia</i> this difference amounts to 57%. Ash contents increase as decapsulated cysts hatch into instar I and molt into instar II-III nauplii. Over a 24h larval developmental period individual dry weights and energy content of the nauplii decrease with 16-34% and 22-37% respectively.A small but significant correlation exists between the survival rate of starved nauplii and either the energy content of instar I and instar II-III... |

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... |

Gonyaulax verior was initially described as Amylax diacantha from Belgian coastal waters a century ago but its detailed morphology needed restudy. Here, we established nine strains of G. verior by germinating cysts or isolating cells from localities from the European Atlantic to the Caspian Sea and the Pacific Ocean. Both cyst and thecal morphology were examined by light and scanning electron microscopy. SSU, LSU and/or ITS-5.8S rRNA gene sequences were obtained from all strains. Cells of G. verior have a plate formula of Po, 4′, 2a, 6-7′′, 6C, 6S, 6′′′, 1p, 1′′′′ with an L-type ventral organisation, characterised by two either straight or curved antapical horns of variable length. Cysts of G. verior are oval, smooth and contain one or two yellow... |
