摘要: This study was conducted to determine suitable conditions fordisinfecting eggs of gilthead sea bream (Sparus aurata)with glutaraldehyde. Effects the developmental stage (4–8 cells,morula, blastopore closure or heart beating), concentration (C = 200,300or 400 ppm) and duration glutaraldehyde treatment (T= 2 10 min) were investigated. Before closurestage, egg manipulation induced mortality. After this stage, thetoxicity negligible if value theproduct C × T less than 1000. Above value, percentage ofhatching normal larvae decreased imprisoned larvaeincreased. Toxic effects varied according qualityat time treatment. It concluded that 200 ppmglutaraldehyde for 4 min, at attheheart beating acceptable disinfecting seabream 18 °C.
