Abstract
In March, 1983 changes in epidermal ultrastructure were examined in Clupea harengus L. larvae hatched from eggs incubated in four zinc concentrations (0.5 2.0, 6.0 and 12.0 ppm). In addition to the outer and inner epidermal cell types described previously, a third type of cell is present. Ultrastructurally this resembles the epidermal “chloride cells” of Sardinops caerulea Girard, characterised by numerous mitochondria, extensive smooth endoplasmic reticulum and a free surface exposed to the environment. These cells occur on the yolk sac, head and in the regions of the trunk just above the yolk sac. In larvae treated in 12.0 ppm zinc, the cells contain fewer mitochondria with fewer cristae than those in the controls. Smooth endoplasmic reticulum is much reduced forming nodular masses and contains granular osmiophilic inclusions. In larvae hatching from eggs previously incubated in 6.0 and 12.0 ppm zinc, the epidermal cells contain more vesicles, intracellular spaces, and swollen mitochondria and show signs of necrosis. The viability of these larvae is discussed.
