Pemetaan Lokasi Fishing Ground dan Status Pemanfaatan Perikanan di Perairan Selat Madura
Abstract: This research aims
at finding the map of waters quality to predict fishing ground, examining the
determinant of modeling parameter of fish catching region, analyzing catch unit
effort (CpUE) and status of fish utilization. Mapping waters quality parameter
is constructed with method of field sample datainterpolation. Besides, the
mapping of surface temperature and chlorophyll is extracted from satellite image
Landsat. ETM+. In addition, the mapping of catching region is resulted in
scoring and weighting factors. Accuracy test is done by method of RMSE. Fishery
utilization status is acquired from method ofapproaches holistic (production
surplus model). Map waters salinity at straits Madura ranges between 27 ppm -
46 ppm, pH range from 8-9, brightness ranges from 0-2 m. Sea level temperature
from image landsat in dry season ranges from 24,1 0C - 27,3 0C in rainy season
between 24,7 0C - 28,6 0C. Optimum temperature in rainy season is lower than in
dry season. Chlorophyll in dry season ranges between 0 mg/m3 - 19,6 mg/m3, in
rainy season between - 0,02 mg/m3 - 41,95 mg/m3. In dry season, the most
appropriate catching region is 58,04 %, appropriate region 36,99% and
inappropriate region 4,96 %, while in rainy season, inappropriate region
achieves 94,44 %, appropriate 2,89 % andinappropriate 2,65 %. Sea level
temperature accuracy test gets RMSE 2,32 and for chlorophyll content 2,31.
Fishery estimation result pelages get CpUE 0.10ton/trip with utilization status
indicating over-fishing in tahun1997 and fisherydemersal CpUE 0.03 ton/trip
with utilization status indicating a surplus in catching in last three year.
