Studies on the larvae of Megalaspis cordyla along the southwest coast of India were carried out based on the plankton collections of UNDP/FAO/Pelagic Fishery Project, Cochin during September 1971 to 1975. The larvae of Megalaspis cordyla contributed 20% of the total carangid fish larvae. Larvae were identified on the basis of meristic and morphometric characters of the adults. Larval characters of selected stages were described. An attempt was also made to study the seasonal abundance and area of distribution of the larvae and to correlate the same with hydrographic parameters.
