Description Unusual landings of the sailfish Istiophorus gladius (Broussonet) by the
driftnet units, during the 1974-75 and 1975-76 seasons have been reported for the
first time along the Calicut coast. The data on sailfish catches, the gear used
and the area depths of fishing during the two seasons have been presented.
The h'saviest sailfish catch was made in October 1974 (5505.0 kg). The
catch data of the black marlin, Makaira indica (Cuvier) and the blue marlin,
M. nigricans Lacepede, have also been given. Length-frequency studies on the
sailfish during the above-cited seasons indicated that the standard length of the
fish ranged from 1450 to 2590 mm. In October 1974, the dominant modal length
was at 2000 mm. In November and December, both the 1950 and the 2050mm
modal lengths preponderated. In January of 1975, both the 1850 and the 2200mm
modal lengths were dominant. The 2050mm length mode of November progressed
to 2150 mm in December and also in January 1976; it progressed further in
February. The mean standard lengths of the fish have also bsen calculated. Studies
on the stomach contents of the fish revealed that it feeds largely on teleost fishes
and cuttle fishes {Sepia spp.).
