Abstract
This study was conducted to determine the baseline
information on abundance, distribution and size of anchovy eggs and
larvae in Langkawi Island, Kedah: Northwest Coast of Peninsular Malaysia.
Sampling was conducted from 18 to 21 September 2022 at 32 stations with the
larval distribution estimated from the spawning distribution in the previous
month. Larvae were sampled using a larva net with a 500 µm mesh size and sub-surface
horizontal towing was carried out around Langkawi Island. Fish eggs and larvae
samples were observed under stereomicroscopy, identified to the family level
and preserved in 4% formalin. Abundance was calculated using the number of
anchovy eggs and larvae with volume water filtered, standardized to 1000 m3
and distribution was mapped using QGIS 3.2. The results showed that the average
size of anchovy eggs was 1.43±0.01 mm (n=947) and larvae was 3.94 ± 0.14 mm
(n=43). The highest abundance of anchovy eggs occurred in PL12 with 51.8
eggs/1000 m3, distributed in the area near the shore while
highest abundance of larvae in LI 04 with 3.2 larvae/1000 m3 in the coastal area.
Thus, the finding of this study provides the baseline information on the abundance,
distribution and size of anchovies eggs and larvae in Langkawi Island, Kedah. This biological information
can be used as primary data for fishery resources management to ensure the
sustainability of fisheries resources in Malaysia.
