Abstract

The aims of these research were to 1). Analyzed the influence of oceanographic factors such as physics, chemistry and biology of the existence of penaeid shrimp in the Payum coastal waters until Lampu Satu. 2). Determined fishing ground of penaeid shrimp at The Coastal Waters Payum-Lampu Satu; which the basis for shrimp fishing coastal communities. The data were took directly through measuring the oceanography parameters such as temperature, tidal range, water transparency, salinity, pH and abundance of phytoplankton. While the data obtained by weighing the catch of penaeid shrimp catches in every trip. To analized the data regression models were used to determine the influence of oceanographic factors on catches. The results showed that the temperature and water transparency affected the Penaeid shrimp catch while the potential fishing areas in the region of the coordinates 80 33’ 17.61“ S – 80 34.’ 2“ S dan 1400 25’ .95’ E– 1400 25’ 44”E . The total catches around 50 to 69.9 kg.

Abstract

The wealth of fisheries resources of Merauke Regency is indeed very abundant. This is evidenced by the location of the fishing ground for fishermen who only catch from the beach, one of which is located in Payum Beach. This study aims to determine the composition of fish and shrimp catches during the wet season. Drift gillnet was used as a fishing gear during this study to collect the data. A Total of 13 species were captured, such as Mugil dussumieri and Megalops cyprinoides were the most dominant species during this period. However, based on the number, Penaeid shrimp such as Penaeus sp. and Penaeus semisulcatus are found to be very abundant during the wet season.

Abstract

Mayo Swamp is located in Jaya Makmur Village Kurik 4 Kurik District, Regency of Merauke, South Papua Province. It has the potential of aquatic plant which is never exposed and never been studied before. This study aims to identify the species, community structure, and important valur index. The method used in this research is purposive sampling methods, through this method the quadrant 5 x 5m placed in 3 research station, and the total of quadrant was 25 quadrants. Sampling and Analysis held for three months start in August until October 2021. The results show that 4 spesies of aquatic plants successfully identified there are Nephrolepis sp., Stenochlaena palustris (Lemidi), Typha angustifolia (Lidi Air), Nelumbo nucifera (Lotus). Community structure of aquatic plants in mayo Swamps consist of diversity index (H’) the highest is 1,31 and lowest is 0,11 and categorized in low diversity. Eveness index (E) in stasiun I is the highest (0,18), meanwhile in station II and III is 0,3 and cetagorized as low. Furthermore, for Dominance Index (D) the highest goes to station II with 0,75 wand the lowest in station III with 0,29 and it can be concluded that the dominance indez of aquatic plaants in Mayo Swamp Waters in low. Along with that Important Value Index (IVI) was in the same category and species with the higher number of IVI is Stenochlaena palustris (Lemidi) with 95,483.
