Karakteristik Perliangan Dan Aktivitas Bioturbasi Kepiting Biola Di Lingkungan Intertidal Pulau Bengkalis

---

Fiddelr crab is one of the fauna that inhabits the intertidal environment of Bengkalis
Island, precisely in the Selat Baru Village area. Characteristics and conditions of the
intertidal environment which are quite diverse have the potential to affect the shape of
the burrow and the bioturbation activity. This study aims to reveal what species of
fiddler crabs were found, burrows type, bioturbation activity and to indicate the
correlation between the substrate characteristics with burrows type and bioturbation
activities. We divided this intertidal region into three locations. Substrate samples were
taken 10-20 cm from the burrow, use resin for burrows cast and plotted 1 x 1 m for
observation crab bioturbation activity. The fiddler crab species found were, Austruca
annulipes, Gelasimus vocans, and Tubuca rosea. The Austruca annulipes crab has an
“L” shape and dimensions of the burrow, Gelasimus vocans has an “I” shape and
Tubuca rosea has a “J” shape with various measurement results. The fiddler crab
dimensions of the burrows diameter do not have a strong correlation to the length
(RPearson=0.002), depth range (RPearson=0.165), and the hole volume
(RPearson=0.106), in which each of these correlations is not significant (P>0.05).
Fiddler crabs is likely to contribute to the movement of sediment in the soil as a result
of pellet transport, which is approximately 164 g/m2/day pellet transport with an
average fiddler crab density of 28 burrows/m2. This means that the mass of sediment
displaced by these animals is not less than 60,000 g/m2/year or 60 kg/m2/year
Keywords: fiddler crab, burrows, bioturbation, intertidal environment
