    Notes: 1. A wide range of species that are cultivated in commercial mariculture are planktonic during at least part of their life cycle; for example, the larval stages of shellfish (shrimp and molluscs) and the live feeds (rotifers, brine shrimp, copepods) used in the larviculture of marine fish and shellfish. Over the last decades various techniques have been developed to deliver nutrients to these zooplanktonic organisms either through artificial diets or by manipulating the composition of the live prey fed to the carnivorous stages. This paper reviews the methodology that has allowed aquaculturists to gain knowledge of nutritional requirements and may offer interesting opportunities for ecologists to verify the importance of key nutrients in the natural food chain of marine as well as freshwater ecosystems.2. Live micro-algae can be replaced partially or completely in the diet of filter-feeders such as rotifers, Artemia, shrimp larvae and bivalves, by various types of preserved algae, micro-encapsulated diets and yeast-based diets, whereas lipid emulsions and liposomes may be utilized to supplement specific lipid-and water-soluble nutrients, respectively. Microbound and micro-encapsulated diets have been designed to supplement live feed in the culture of micro-predators such as fish and shrimp larvae.3. Live prey organisms, in particular rotifers and Artemia, can be ‘bio-encapsulated’ with a variety of enrichment diets to manipulate their content in certain nutrients, including ω3 highly unsaturated fatty acids (FA) and the vitamins C, A and E. Nevertheless, the enrichment techniques are not applicable for all nutrients and prey organisms. Phospholipid composition is difficult to manipulate through the diet of live feed and the enrichment of the essential FA docosahexaenoic acid (DHA) is hampered in most Artemia species due to the catabolism of this FA following enrichment.

    Artemia tibetiana: Preliminary characterization of a newArtemia species found in Tibet (People's Republic of China). International Study onArtemia. LIX (1998)

    Notes: Abstract In this study, we report on the existence of a new bisexualArtemia species, found in the high plateaus of Tibet (P. R. China). Different disciplines have been used to characterize this new population: biometrics of cysts and nauplii, morphometry of adults, cytogenetics, allozyme and DNA analyses and cross-breeding/fertility tests with knownArtemia species. The results obtained justify that there is enough evidence to support the view thatArtemia from Tibet is a new species with the proposed nameArtemia tibetiana.

    International Study on Artemia LVIII. Morphologic differentiation and reproductive isolation of Artemia populations from South America (1998)

    Notes: Abstract Six Artemia populations from coastal and inland sites in Chile, ranging from 20 to 50 degrees latitude south, were compared morphologically. The study included reference samples of A. franciscana (San Francisco Bay, California-USA) and A. persimilis (Buenos Aires, Argentina). These species are likely to be found in Chile. Samples from Peru (Piura) and Brazil (Macau, Rio Grande do Norte) are two known examples of deliberate introduction of A. franciscana. The hypothesis of A. franciscana being the dominant species in South America was tested by multivariate morphological analysis based on ten body measurements. In addition, laboratory cross-fertility tests were performed in order to evaluate levels of reproductive isolation among these widely distributed populations. The analysis showed that A. franciscana and A. persimilis are morphologically divergent. A number of populations overlap with the San Francisco Bay sample, two are morphologically close to Buenos Aires, whilst others lie morphologically in between. Interpopulation morphological differences along with geographical and, probably, ecological divergence do not reflect reproductive isolation, at least of the pre-mating type. The morphological similarity of two Chilean samples with A. persimilis suggests that the distribution of A. persimilis should be further investigated. A multi-trait approach for Artemia characterization is stressed as a way to obtain better descriptions and interpretations of the biological diversity in the genus.

    First record of Branchinella spinosa (Milne-Edwards) (Crustacea: Branchiopodacolon; Anostraca) from Greece (1999)

    Notes: Abstract As the result of a first screening of temporary inlandwater habitats, Branchinella spinosa is hererecorded for the first time in Greece. This findingextends the circum-Mediterranean part of its vastdistribution. The species was collected from a shallowastatic coastal salt-marsh that is mainly fed byrainwater, where it coexists but rarely co-occurs withArtemia parthenogenetica. Branchinellaspinosa is only the fourth anostracan speciescurrently known from Greece. The poor knowledge ofanostracan richness and abundance is mainly due tolimited sampling efforts in this area. As temporaryaquatic habitats are threatened by severalanthropogenic activities, especially agriculture andland clearing for urbanisation and tourism, there isan urgent necessity for further monitoring andprotection of these precious habitats.

    International study on Artemia XLIX. Salinity effects on survival, maturity, growth, biometrics, reproductive and lifespan characteristics of a bisexual and a parthenogenetic population of Artemia (1995)

    Notes: Abstract Two Artemia populations, a bisexual from San Francisco Bay (California, USA) and a parthenogenetic from Tanggu area (Tianjin province, People's Republic of China) are assayed for their tolerance and fitness in various salinity levels. This study was carried out under laboratory conditions where salinity effects upon special characteristics of the two Artemia populations, such as survival, growth rate, maturation, morphology, fecundity and life duration, were recorded. This evaluation revealed that the two populations examined exhibits significant differences in their response against elevated salinity levels. Furthermore, specific biometric parameters can be a useful tool for the discrimination and/or determination of their distribution in a mixed population, which, in fact, is the case in Tanggu salt works. Artemia franciscana seems to be a more effective colonizer at higher salinities. The data presented in this study may generate useful suggestions for proper management of the solar saltworks at Tanggu although further experimentation is needed.

    Notes: Abstract Eleven morphometric and one meristic character in 15 parthenogeneticArtemia populations have been studied by using discriminant andcluster analysis as well as scanning electron microscopy.Discriminant analysis revealed five main groups of morphologicalpatterns: (i) the coastal Chinese populations together with apopulation from Kazakhstan, (ii) the inland Chinese salt lakepopulations, (iii) the Greek populations, (iv) one African populationfrom Namibia and (v) a Chinese population from Xuyu (Jiangsuprovince). Cluster analysis was not always in agreement withdiscriminant analysis and these results are discussed.

    Notes: Abstract A detailed morphological and allometrical study was performed withadult males and females of eleven bisexual populations of brineshrimp Artemia. Multivariate procedures, discriminant andcluster analysis, allowed to separate and group together populationswhich exhibit great genetic similarities. The eleven populationsstudied form four distinct groups: the A. franciscana group,the A. tunisiana group, the A. urmiana group and abroader group which includes Eastern Old World populations. Scanningelectron microscopy revealed differences in the male genital organsof an A. tunisiana population by lacking a medial protuberancein the base of the penes while the pattern of the ectodermal ridgesof the brood pouch of A. urmiana markedly differed from theother populations studied.
