摘要: Abstract Different yeast strains are considered as best alternative feeds for rearing brine shrimp, Artemia franciscana , nauplii. The feeding effects of Saccharomyces cerevisiae (Baker's yeast) wild type strain and mnn9 mutant were investigated by stereological tools using the gnotobiotic system model. Gnotobiotic A. nauplii fed daily with dead Aeromonas hydrophila LVS3, either baker's or mnn9, which cell wall contains elevated chitin glucan lower mannose levels. Mean survival percentages, individual length, total volume surface area digestive tract segments in relation to length compared between both groups at 2, 4 6 days after hatching. ratios midgut group further day 6 respectively 0.82 ± 0.01 0.76 ± 0.01, 4335.0 ± 72.1 2130.5 ± 211.4 μm 2 1641.9 ± 55.6 465.5 ± 56.1 μm significantly different ( p
