| Summary: | Monopterus albus production in Malaysia is widely
depends on wild stock. Otolith morphology has been widely used
to give additional information that is crucial for aiding the seed
production. Otolith morphology of Asian swamp eel, Monopterus
albus and its relationships to fish size was examined. A total of
125 samples were collected from the East Coast of Peninsular
Malaysia (ECPM) and Sabah for analyses. Otolith descriptions
were based on its outline, including otolith length (OL, mm),
otolith height (OH, mm) and otolith weight (OW, mm). Fish total
length (TL, cm) and body weight (BW, kg) were also measured
and recorded. Paired t-test result (p-value > 0.05) showed there is
no statistically significant difference between left and right otolith
dimensions. Regression models related to otolith morphometric
parameters with eel length and body weight were determined.
There is no morphological difference between left and right
otolith of swam eel observed. Otolith weight is a good indicator of
body weight (R2
=0.8994) and total length of fish (R2
=0.8707)
since the R2
value is strongest than other relationship. If the
otolith weight used to estimate the length and body weight of eel,
the regression explains more than 87% of data variation in this
Monopterus albus. |
