| Seven Meyliidae-species are described, four of them are new: <i>Boucherius spinosus</i> (Gerlach, 1956) comb.n., <i>B. floridanus</i> sp. n., <i>Gerlachius lissus</i> (Gerlach, 1956) Andrassy, 1976, <i>Meylia alata</i> Gerlach, 1956, <i>M. vangoethemi</i> sp. n., <i>Noffsingeria omeri</i> gen.n., sp.n. and <i>N. grandiamphis</i> sp.n. The different types of ornamentations of the body cuticle are considered significant features, separating the seven species in four genera, two of which were already described: <i>Meylia</i> Gerlach, 1956 and <i>Gerlachius</i> Andrassy,1976 and two new genera: <i>Boucherius</i> gen.n. and... |

| Two new <i>Epsilonema</i>-species are described: <i>E. parvospina</i> sp.nov., characterized by the ornamentation of the body cuticle and the single ventral row of 3 to 5 copulatory thorns in male and <i>E. longispicula</i> sp.nov., characterized by the ornamentation of the cuticular body rings, long spicus and two single ventral rows of copulatory thorns in male. A new genus <i>Triepsilonema</i> with a new species <i>T. tripapillata</i> gen. n., sp.n. is described. <i>Triepsilonema</i> is mainly characterized by the six rows of ambulatory setae and the separate outlet for each of the three caudal glands. New information is given on <i>Apenodraconema spinicaudum</i>... |

| When considering zooplankton feeding as one of the pathways involved in the transfer of substances in marine ecosystems, it is important to study the composition and size distribution of the seston: firstly, the elements in which one is interested may be associated with different types and sizes of particles; secondly, particle size and composition are important factors in relation t o the feeding process of the zooplankton itself. High speed cinematographic studies have recently revealed that copepods use two different mechanisms for feeding. Small particles (< 12 pm) are collected by continuous low amplitude movements of the second maxillae and combing of the appendages. Larger particles are detected and collected individually by means of a specific... |

| Decapsulated <i>Artemia</i> cysts were used to study the factors which induce the superior performance of live organisms as food for fish larvae. The biochemical composition, the in vitro protein digestibility, and the total proteolytic and trypsin activities in cysts and nauplii of <i>Artemia</i> were determined at different developmental stages as a function of incubation time. Six different incubation times were studied: 1, 6, 11, 16, 21 and 25h of development, which cover cyst and early nauplii stages. The individual dry weight of <i>Artemia</i> decreased through development. The individual protein and lipid content (µg ind<sup>-1</sup> remained constant during development until the time of hatching after... |

| This study describes the variations in total lipid, lipid classes and fatty acids in the midgut gland (MG), ovary, and muscle tissue of wild-caught <i>Macrobrachium rosenbergii</i> to elucidate the importance of these components during sexual maturation. Mature females were captured in the Mae Klong River, Thailand, from July to September 1998, and divided into five groups according to their ovarian development. Total lipid levels in the ovary increased with maturation, but no concomitant decrease in MG lipids was observed. Thus, the lipid requirements of the developing ovary are thought to be more dependent on the immediate ingestion of dietary lipid than on MG reserves. Higher proportions of neutral lipids (NL), mainly triacylglycerols (TG),... |

| For characterization of strains of the brine shrimp <i>Artemia</i> of different geographical origin, a standard culture test has been developed in order to compare statistically growth and survival of larvae of different strains. 25 geographical strains have been studied so far -including, for 3 strains, analyses of cysts harvested at different times. Important differences in rates of growth and survival were observed between strains but not among batches of the same strain. Best performances were noted for strains from Bahia Salinas (Puerto Rico), Buenos Aires (Argentina), Chaplin Lake (Canada), Great Salt Lake (Utah, USA), Galera Zamba and Manaure (Colombia). |

| Cysts (encysted gastrula embryos) of <i>Artemia franciscana</i> collected from salterns in San Francisco Bay, California, USA (SF) were inoculated into much warmer growth ponds in the Mekong Delta region of Vietnam (V) in 1996. V adults arising directly from these cysts during 17 April to 15 May produced their own cysts, which were collected, processed and stored until shipped to the USA for study. Adults grown in the laboratory from SF cysts (those used for the inoculation) were less resistant to high temperature than adults cultured from V cysts. V cysts produced heat-resistant adults, even though cultured under the same laboratory conditions as SF animals, at much lower temperatures than they ever experienced in Vietnam. Differences in... |

| There has been rapid development in the marine foodfish larviculture technology in Europe since the early eighties, especially in the flat fish, turbot and halibut, and the bass and bream species. The most significant improvements in the eighties were the introduction of light control, artificial reproduction techniques, appropriate water treatment and the use of rotifers and <i>Artemia</i> nauplii of specific sizes and in the late eighties and early nineties the quality enhancement of live food organisms using specific enrichment techniques. Present research is focused on the implementation of several microbial techniques to improve the hygiene of live prey and fish. Many of the modern larviculture techniques being used in marine foodfish... |

| Phytoplankton response to environmental pollution by oil and emulsifiers has been studied. The nanoplanktonic flagellate <i>Platymonas tetrathele</i> has been assayed with increasing concentrations of crude oil, industrial non-ionic emulsifiers and mixtures of these products. Cultures poisoned with an emulsifier with an aromatic solvent exhibited a very long lag phase. Diminished growth rates were observed for all the products tested most of the time at concentrations above 50 ppm. The mixtures showed a toxicity close to that of the emulsifier component at its concentration in the mixture and lower than that of the crude oil alone. Fine structure modifications have been investigated and the possible ecological effects of such pollution have... |
