Zebrafish embryos at six developmental stages were exposed to the supernatant of homogenates of zebrafish embryos, 5-day chick embryos and 9mm frog larvae. Extracts of embryos bring about developmental arrest of the zebrafish embryo at stages 17-18. The effect is reversible. Arrested embryos returne

## Abstract Developmental stages, from eight cells to 28 days postβhatching, of the zebrafish, __Brachydanio rerio__, were analysed by immunoelectrophoresis with unabsorbed and absorbed rabbit antiserum to adult zebrafish brain. From the earliest embryonic stage to the oldest postβhatching stage te
## Abstract Organ and tissue supernates of the zebrafish, __Brachydanio rerio__, were analysed by immunoelectrophoresis with unabsorbed and absorbed rabbit antiserum to adult zebrafish brain. Four brain specific antigens were detected.
## Abstract Embryos of __Brachydanio rerio__, stage 10 (Hisaoka and Battle, '58) were exposed for 24 hours to graded concentrations of ethanol from 1 to 3%. Developmental abnormalities included defects of the eye, i.e., approximation, confluence and fusion of the optic cups midβventrally; as well a
