| Abstract: | For a distinct autochthonous Austrian coregonid population called Reinanke Coregonus sp., embryo viability was very low in Zuger jars (mean ± s.d. 36·1 ± 16·1% eyed stage embryos in experiment 1, 15·1 ± 17·0% in experiment 2) but high in vertical flow incubators (63·3 ± 29·0% eyed stage embryos in experiment 1, 57·8 ± 18·9% in experiment 2). Mechanical shock sensitivity is a possible explanation for high embryo mortality. |
