Ecology of Kajikia audax
 
Main Ref. Nakamura, I., 1985
Remarks There is little information on the distribution of striped marlin eggs and larvae (Ref. 6390). Juveniles are relatively rare in the southwest Pacific Ocean (Ref. 30443). Fish of 4-10 kg (80-100 cm FL) are regularly caught on longlines in the region but concentrations of fish this size are most restricted to the northcentral Pacific Ocean (Ref. 30443). Striped marlin are carnivorous, non-selective feeders whose diet includes more epipelagic organisms than the diets or other billfish and larger tunas (Ref. 6390). Their diet changes with season and locality (Ref. 6390).
