Abstract
This research was conducted in January 2021 in the mangrove area of
Gogok Darussalam Village, Meranti Islands Regency, Riau Province with the aim
to know the abundance and distribution pattern of Thalassina anomala in the area.
The method used is a survey method. Sampling used line transect method.
Sampling was carried out by drawing three transect lines, starting from the lowest
low tide line along 45 m inland at each station. carried out on square plots
measuring 5m x 5m. The parameters measured were temperature with an average
value of 27.7 oC, salinity with an average value of 26.7 ppt and pH with an
average value of 6.8. The results showed that the Thalassina anomala found in the
mangrove area of Gogok Village, Meranti Islands Regency, Riau Province were
6.6 ind/25m2 or 2,640 individuals per hectare. Meanwhile, the distribution pattern
of the Thalassina anomala in the area is completely random. The moths live in
nests with sediments with low bulk density values, namely on fine-textured soils
and granular structures with bulk density values between 0.1 - 0.9 grams/cm3.
Sediment organic matter in Gogok Darussalam Village, Meranti Islands Regency,
Riau Province ranges from 42.1833% - 58.1833%.
Keyword: Gogok Darussalam Village, mangrove area, Thalassina anomala,
