| Summary: | This study examined the diversity of mudskipper species in Sabah and estimate
possible factors affecting their abundance. Desktop studies and fieldtrips were made
to verify existence of mudskipper species in Sabah after taxonomic revision of Murdy.
Abundance of mudskippers was studied between 4 study areas: A (Kota Kinabalu
Wetland Centre), B (Alamesra), C (UMS-ODEC), D (Marudu Bay) where the factors
examined are water parameters (temperature, conductivity, salinity, DO, pH) and
environmental conditions (exposure, structural element, sediment composition,
vegetation coverage) of the habitat. Fieldwork was done between November 2014 to
February 2015. A total of 24 specimens obtained from 4 locations (Alamesra, UMS-ODEC,
Marudu Bay and Sandakan) were used to obtain morphometric and meristic
data. The mudskipper species found in this study are: Boleophthalmus boddarti,
Periophthalmodon schlosseri, Periophthalmus argentilineatus. Other gobioids and
blennies obtained were examined for morphometric and meristic data and presented.
The abundance of mudskipper population was found to be Significantly different
between stations ׀A, B׀ and ׀C, D׀ (N=180, Fl,66.06=174.28, p<0.001). Principle
component analysis of water parameters and environmental conditions suggested
there are two principle components that may affecting mudskipper abundance. |
