Post‐larval growth in the lateral white muscle of the eel, Anguilla anguilla
The post‐larval growth of lateral white muscle was studied in eels at different stages of post‐larval development (glass, yellow and silver eels) by means of histochemical methods for myosin‐ATPase (mATPase) activity, immunohistochemistry (for myosin isoforms) and electron microscopy. Morphological,...
