Abstract
Cod eggs and larvae (Gadus morhua L.) were exposed to oil in concentrations from 50 to 280 ppb, and the cells of the skin were studied in order to reveal any abnormal development, by means of light microscopy, scanning electron microscopy, and transmission electron microscopy. No significant differences were observed between the larvae exposed to the oil and the controls. This refers to the number and concentration of the mucous cells, the chloride cells, and the hatching cells. In this investigation, no gross morphological changes were observed.
