ABSTRACT

The importance of information on the availability of fish resources in
an area is the main reason for conducting a comprehensive study
that is able to provide data and information on the potential of fish
resources. Several techniques and methods need to be studied for
the provision of potential fish resources data. This research is closely
related to the theme carried out by FST of Universitas Terbuka in 2023,
namely Trends in science and technology for sustainable living.
This study aims to describe the potential of small pelagic resources
through mapping fishing ground, catches, and their relationship
with the main factors of oceanography, namely chlorophyll-a and
Sea Surface Temperature (SST). The study was conducted in the
Makassar Strait in 2015, fisheries data time series collecting for 10
years (2006-2015) obtained from Pekalongan Fishing Port (Central
Java), Batu Licin Fishing Port (South Kalimantan), and Paotere Fishing
Port (South Sulawesi). Secondary data of time series environmental
parameters for 10 years (2006-2015) are Aqua-MODIS and SNPP-
VIIRS satellite imagery. Analysis of Aqua-MODIS and SNPP-VIIRS
satellite imagery using ArcGIS while analysis of small pelagic fish
catch data using statistics and descriptive, then overlays were
carried out to explain the correlation of SST and chlorophyll-a with
catches. The results showed that the average monthly value of
SST ranged from 28.02°C - 30.53°C and SST was relatively higher in
the Transition I Season compared to the Western Season and East
Season, recorded the range of chlorophyll-a concentration values
was 0.25 mg/m³ - 0.62 mg/m³. The average monthly chlorophyll-a
concentration value fluctuates, according to the ongoing munsoon
season. The maximum mean value of chlorophyll-a is recorded
in the Western Season, while the minimum mean value is in the
Transition II Season. Banyar fish (Rastrelliger spp.), bentong (Selar
sp.), and lemuru (Amblygaster sp.) showed a positive correlation to
chlorophyll-a, while layang (Decapterus spp.) showed a negative
correlation. Banyar, bentong, and layang fish showed a negative
response to SST, while lemuru fish showed a positive response. The
