and fishing effort and mire recent data on skipjack tuna sizes and sexual
maturity permit descrif¢tion of
the fisherv.
In 1936, the Japanese had
between 9 and 32 vesseis im the skipjack tuna fishery at Falau each month.
Menthiy catches ranged from 9.7 metric tans in February tc 779.4 metric
tors im December, The number of fishing trips ranged from £6 in February te
aS many as 412
ain Jure.
Catch per trip varied from 0.3 metric ton in
February tea
1.4 metric tone in November. The everace size of the skipjack
tuna varied fram month ta month between 36 and fe cn. in 1936; in 1965-47,
they ranged between 48 anc 62 cm. For all years in which size data were
wamined,
the average size tendsd strongly to increase in Oztober-January.
