Abstract

One of the regions contributing to stingray fisheries production in Indonesia is Aceh province. The condition of stingray fisheries in Indonesia is currently facing challenges as the population is decreasing while the demand for stingray fishery resources domestically and abroad continues to increase. This condition certainly requires integrated stingray fisheries management efforts so that the rays population, especially in the waters of Aceh province, remains sustainable. This study aimed to determine the number, type, and distribution of stingray fishing grounds landed at the Ujong Baroh Fish Landing Base (PPI). The research was carried out in 2 stages; the first stage was to conduct a field survey by following fishermen directly to the sea and using interview questionnaires, and the second stage was to take satellite image data of sea depth, fishing location, and fishing distance and then make a map of stingray fishing ground distribution landed at Ujong Baroh Fish Landing Base, West Aceh. The number of stingray catches landed at Ujong Baroh Fish Landing Base during the study was 428, consisting of 11 species: 369 Maculabatis macrura, 42 Myliobatis tobijei, 14 Rhynchobatus australiae, 28 Dasyatis kuhlii, 8 Pateobatis uarnacoides, 7 Gymnura zonura, 6 Himantura leoparda, 2 Rhina ancylostoma, 2 Rhinobatos borneensis, 1 Aetobatus narinari, and 1 Taeniuriops meyeni. The results of the mapping analysis showed 18 distribution points of stingray fishing grounds and 4 fishing locations that obtained stingray catches, namely at the coordinates of 338.136'N and 9629.056'E, 42.144'N and 962.431'E, 416.599'N and 9532.000'E, 334.51472'N and 9625.80414'E.Keywords:MappingFishing GroundStingrayEastern Season

Abstract

Graphical Abstract   Highlight Research The number of shark catches in the eastern season was 618. Sharks landed at PPI Ujong Baroh in six species (Sphyma lewini, Alopias pelagicus, Carcharhinus falciformis, Loxodon macrorhinus, Carcharhinus sorrah, and Chiloscyllium punctatum). The distribution of chlorophyll-a parameters in the eastern season ranges from 0.08 to 1.23 mg/m3 with an average value of 0.17 mg/m3. The distribution of sea surface temperature parameters in the eastern season ranges from 27.65 to 30.29oC with an average value of 28.65o Based on linear regression analysis, sharks are most highly influenced by chlorophyll-a oceanographic parameters, namely Loxodon macrorhinus by 72.82%, and sharks are highest influenced by sea surface temperatures, namely Alopias pelagicus by 83.12%.     Abstract  Sharks are top-tier water predators that can maintain marine ecology balance and control the food web. As sharks are at the top of the food chain, their overfishing can disrupt the ecosystem chain. The distribution and abundance of fish in waters can be influenced by several factors of oceanographic parameters, including chlorophyll-a and sea surface temperature (SST). The use of satellite imagery for analyzing chlorophyll-a and SST parameters provides significant results in fisheries oceanographic studies. This study aimed to determine the effect of chlorophyll-a and SST parameters on shark catches. The method in this study was divided into 2 stages, namely taking shark fishing area coordinate data and downloading chlorophyll-a as well as SST satellite image data on the NASA Aqua-MODIS website. The results of the of the analysis of chlorophyll-a distribution in the eastern season ranged from 0.08 to 1.23 mg/m3 with an average value of 0.17 mg/m3, where the highest was 1.23 mg/m3 in September and the lowest was 0.08 mg/m3 in August. The SST distribution ranged from 27.65 to 30.29oC with an average of 28.65oC, the highest was 30.29oC in August and the lowest was 27.65oC in September. Based on the results of linear regression analysis, the highest shark catch was influenced by chlorophyll-a, namely Loxodon macrorhinus shark, by 72.82%, the highest shark catch type was influenced by SPL, namely Alopias pelagicus shark, by 83.12%, and the rest was influenced by other parameters.
