Abstract
Muar area is the mussel culture area especially in culturing green lipped mussel
(Perna viridis). The availability of wild seed of green lipped mussel, this makes it easily
to culture on the rope collector at the mussel platform. This study investigates the
recruitment and early growth of Perna viridis at the rope collector and at the sea bottom.
For rope collector, it divided into three parts which is upper, center and bottom part.
Recruitment of Perna viridis spat in Muar coastal water shows highest peak on the
beginning of August (24,900 indv/m
2
) and it slowly decrease on the next month until the
end of September shows the minimum recruitment (222.22 indv/m
2
). The next month
shows the recruitment slowly increases. While for the early growth shows the
acceleration of growth rate increases 0.11 mm/week·

or 0.0002 mm/day"

When rope
divided to three parts, the recruitment on the center part shows highest settlement (35,000
2
indv/m
) compared to the upper part (27,500 indv/m
2
) and the bottom part (12,200
2
indv/m
). For the early growth, on the initial 11 weeks shows highest growth of Perna
viridis at the upper part, after 11 weeks the upper part shows declining on growth and the
Perna viridis at bottom part shows increasing growth.
