Satellite Imagery and In-situ Data Overlay Approach for Fishery Zonation
Abstract: Remote sensing
technology is useful to give a better understanding about the earth’s
characteristics. SeaWiFS (sea-viewing wide field-of-view sensor) is one of
remote sensors used to observe global ocean phenomena. Previous studies showed
that the distribution of chlorophyll-a in the ocean indicates the presence of
fish. However, only a few studies tried to directly relate the chlorophyll-a
distribution obtained through interpretation of satellite imagery to in-situ
data of fish distribution. This paper investigates the relation between
chlorophyll-a distribution and fish-capturing points in Aceh Province sea
waters using overlay image analysis. The results are useful to identify the
potential fishing ground in Aceh. The profile of chlorophyll-a concentration
was derived from SeaWIFS satellite imagery and fish-capturing points data was
obtained from the fisherman communities of Banda Aceh, starting from June to
November 2008. The results show that the chlorophyll-a profile derived from
satellite imagery has a positive relationship to fish-capturing point data. The
most potential fish-capturing zone in Aceh sea waters is identified at 5-8º
north latitude (N) and 96-99º east longitude (E).
