Neuromasts and cupular growth of cod larvae. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983

Use of phase contrast microscopy and vital staining showed that newly hatched cod larvae had five free neuromasts on either side of the body and four on the head. About three weeks later, when feeding was established and the larvae had reached 5-6 mm body length, there were six on either side of the body, six scattered over the head and a row of four above the mouth. By use of staining under anaesthetic, followed by recovery, it was possible to measure the growth of the cupulae which averaged 2.4 um/h
