Abstract
Environmental parameters viz. surface temperature, salinity, dissolved oxygen, zooplankton biomass and availability of forage fishes were studied in relation to surface tuna fishery at Minicoy Island. A surface temperature range of 28°C to 31 °C and salinity around 34 %o were found to be optimum for tuna schools. Dissolved oxygen was not found to act as a limiting factor. Zooplankton biomass was found to influence the tuna catch indirectly through the abundance of forage fishes.
