“…The water temperature data was collected using a measuring instrument, namely a digital thermometer, water salinity with refractometers, water pH with digital pH meters, water turbidity with digital turbidity meters, and sediment with a hand core sediment sampler (Dias et al 2018;Equbal et al 2018;Wan et al 2020). Water temperature and pH measurements are conducted by dipping the measuring instrument into the water surface and recording the indicated values (Sari 2020).…”

Abstract. Lantang B, Najamuddin, Nelwan AFP, Samawi MF. 2023. Density distribution of Penaeus merguensis De Man, 1888 based on habitat in the waters of Merauke District, South Papua Province, Indonesia. Biodiversitas 24: 4427-4437. The waters of Merauke District, located in the Arafura Sea area, have relatively hight penaeid resource, but prawn fishing productivity is the lowest of 11th other Indonesian fisheries management areas.. The optimization of the fishery resource utilization remains poor after the moratorium on fishing vessel licensing in 2014, which is only 11%. Hence, a study is needed to determine the resources’ distribution, abundance, and sustainability. This research aims to analyze the density distribution of banana prawn (Penaeus merguensis De Man, 1888) based on the habitat type, each location separated by ~4-5 kilometers within the coastal ecosystem waters of Merauke District. The research was carried out from March to August 2022. Data were collected within each habitat: the catch, prawn fishing equipment, and oceanographic parameters, and then analyses were undertaken using statistical tests. The results showed that the highest density of banana prawn was obtained in shallow waters adjacent to the mangrove habitat at Bokem (32.68 kg/km2) and Yobar (20.27 kg/km2). In waters adjacent to the sandy beach at Payum (17.98 kg/km2), the density was higher than within the estuarine habitat of Maro River (14.60 kg/km2) and adjacent to the sandy beach at Lampu Satu (14.39 kg/km2). This is due to the influx of fresh water in estuarial habitat, sandy beaches in Lampu Satu and Payum, and mangroves in Yobar, resulting in prawn emigration to areas with higher salinity in Bokem mangroves. It is also thought to be associated with increasing turbidity with a similar pattern in salinity and affecting the density of banana prawns.

The horizontal distribution of plankton communities in a subtropical mixed estuarine system over one tidal cycle was investigated. Hydrological and planktonic samples were obtained twice on 17 July 2007 in a transect with ten stations in the Babitonga Bay estuary, south Brazil (~26°S). Hydrological variables did not vary spatially or tidally during samplings. However, in the cluster analyses both phyto and zooplankton were structured according to their estuarine position and in the inner stations also by the tidal condition. Phytoplankton abundances were higher during fl ood tide in the inner estuary (max. 122,583 ind.L -1 ), where diatoms dominated, particularly Diploneis bombus. However, the density at ebb tide increased towards outer estuary (max. >100,000 ind.L -1 ) and fl agellates, mostly Gymnodinium spp., became abundant.Zooplankton abundances were higher at intermediate stations during both tides (max.13,691 ind.m -3 ). The innermost stations were dominated by the copepod Acartia tonsa, while in the outermost stations Temora turbinata and the polychaete larvae Loimia sp. dominated. The results demonstrate how variable the estuarine plankton horizontal structure can be over short time-scales even in mixed estuarine systems under relatively homogeneous conditions, highlighting the importance to consider such temporal scales for a more accurate understanding of the dynamics of these communities.
