Tuna, squid and octopus accounted for the highest proportion of the exports.
Bivalve mollusk exports soared 39 percent to $99.6 million.
The five biggest markets for squid and octopus were Korea (accounting for 41 percent), 11 member countries of the CPTPP (24 percent), Thailand (11 percent), EU (10 percent), and China (7 percent).
In September alone, exports fell by 24 percent year-on-year, after falling by 24 percent in August, due to social distancing restrictions.
VASEP expects the figure to also decline in October.
