Madagascar started exploring longline fishery in 2007 by shifting from trawl gear to small longliners. The number of vessel, targetting tuna and tuna like species, has been increasing. In 2012, the Madagascar deployed eight fishing vessels less than 24 m off the east coast. Note that some of them are multigear, wherebery fishing vessels may target demersal resources and at othertimes they may target tuna and tuna like species. The following results were obtained from the malagasy observer program database and from pelagic species companies’ declarations. With 388 178 hooks, the total catch was 388 tons which are composed of 44.66% tuna, 25.38% billfish, 13.24% shark and 16.72% others species. Billfishes percentage landed comprised mainly of 73.54% swordfish. The contributions of two other species are 19.15% and 7.31% corresponding to striped marlin and other other Istiophoridae , respectivly. Thus, CPUEs for swordfish and striped marlin were 186.8 Kg/1000 hooks and 48.6 Kg/1000 hooks, respectively. Their lenght-weight relationships were calculated as Wswordfish= 10-5 LJFL2.9735 and Wstriped marlin=4x10-4 LJFL2.7064.
