Examination of published information on temperature, oxygen and other enviromental prefrences of tuna like fishes suggests that the Nigerian EEz should have commercial quantities of fishes. ICCAT historical catch and effort data analysed are confirmatory. given the prevailing low level of maintenance conciousness, initial investmnt and skills required, purse-seine may not be decidedly superior to pole ond line as capture technique. Prefered size of vessel type and gear specific scenarios are described. It appears that fuel costs can attract some of the multinational fleets to Nigeria and that transhipment facilities and a local canery are advantageous.
