Weight-Length Relationships for Certain Scombroid Fishes from the Equatorial Western Indian Ocean.
The East African Marine Fisheries Research Organization (E.A.M.F.R.O.) is at present conducting a tuna longline survey in the equatorial western Indian Ocean. During this survey, which began in September 1964. The weights and lengths of all specimens of scombroid species caught have been recorded. Sufficient data have now been collected from three species of tuna and two species of billfish to enable the calculation of reliable weight-length relationships. The species of tuna considered are the yellowfin, Thunnus albacares (Bonnaterre), albacore. Thunnus alalunga (Bonnaterre) and skipjack, Euthynnus pelamis (Linnaeus). The billfish examined were the striped marlin. Tetrapterus audax Phillipi and the sailfish, Istiophorus gladius (Bloch).
