Modelling several morphometric relationships of swordfish (Xiphias gladius), black marlin (Makaira indica) and blue marlin (Makaira nigricans) caught from Indonesian longliners in the eastern Indian Ocean

Journal of Fisheries, 2016
This paper presents several equations for converting among measures of size (length and weight) for swordfish (Xiphias gladius), black marlin (Makaira indica) and blue marlin (Makaira nigricans) caught by Indonesian longliners in the Indian Ocean.

Pugnacity of Marlins and Swordfish [PDF]

Nature, 1956
FROM a wide area of the sea there have been reported occasional incidents illustrating the pugnacity of marlins and swordfish. This has been supported by recent evidence from South African seas, as a result of the Second World War, when a number of ships from the East were torpedoed in the Mozambique Channel.

Feasibility of a Close-Kin Mark-Recapture for Stock Assessment of Indian Ocean Swordfish (Xiphias gladius)

Fishes
The Indian Ocean Tuna Commission (IOTC) manages swordfish, Xiphias gladius, a species of high economic importance in the Indian Ocean. Current stock assessments rely on catch per unit effort indices, which can be biased, complicating reliable abundance ...
