During the second voyage of the Research Yessel Kalava in the Laccadive Sea a juvenile sailfish was collected at about 4 a.m. on 10-4-1959 from Station No. 436 (Lat. 10° 32' N, Long. 74°35' E.) and was kindly passed on to me for study by my colleague Dr. R. Raghu Prasad. The fish had come near the vessel attracted to light and was caught with the help of a dip net.
