A maximum frond length of M. pyrifera was reached
after 120 to 150 days of cultivation in the sea (Fig. 3).
Values varied with the time of the year (p0.01) in the final length of the fronds
between both methodologies (Table 1).
Maximum biomass was obtained after 120 to 150 days
of cultivation in the sea (Fig. 4). Similar to sporophyte
length, the accumulation of biomass varied with the season
(Table 1). A maximum of 22 kg m−1
of rope was observed
after 120 days of cultivation in September (Fig. 4). There
were no significant differences in biomass between both
culture methodologies. However, there was a first-order
