Abstract

The purpose of this study was to see the abundance and distribution of mullet during the day and night on the coast of Lampu Satu Beach and Payum Beach. This research was conducted in June-August 2020. Determination of the sampling points at the research location using purposive random sampling method. Data analysis used in this research is Relative Abundance (Kr) and Morisita Spread Index (Id). Catches found during the study were 268, with 3 species of mullet, namely Mugil cepalus, Mugil dussumieri and Rhinomugil corsula. During the day, the total number of catches is 148 while at night it gets as many as 120. The highest proportion value of relative abundance was obtained from the two stations, namely Mugil dussumieri species and the lowest was Rhinomugil corsula. The results of the calculation of the morisita distribution index during the day at both stations obtained a value of 1.008 (group). It is also found that at night the two stations get a value of 1.014, which means that at night it is a group category.

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.

Abstract. Lantang B, Najamuddin, Nelwan AFP, Samawi MF. 2024. Prey conditions, food habits, and their relationship to the catch of Penaeus merguensis De Man, 1888 in the waters of Merauke District, Indonesia. Biodiversitas 25: 1554-1569. The study of the food habits of commercial crustaceans, namely Penaeus merguensis De Man 1888 in the waters of Merauke District was limited. Hence, research related to this was needed. For this reason, the study aims to analyze the prey fragment, prawn food habits, and their relationship to the catch based on differences in habitat types in the coastal waters of Merauke District. Data measuring oceanographic parameters, gastric contents samples of banana prawn (P. merguensis), mollusk samples, and catches were taken twice monthly in five habitats from March 2022 to March 2023. The results showed that for the fragmentation of prey, namely microalgae, 76.12% was found intact, while mollusks were found 97.46% not intact or dismembered. Mangrove leaves, macrophytes, prawn larvae, and fish larvae were found to be 100% incomplete or dismembered. Microalgae and mollusks were the main food in estuarial habitats and sandy beaches in Lampu Satu. While in mangrove habitats in Yobar, sandy beaches in Payum, and mangrove habitats in Bokem, the main food is mollusks, and complementary foods are microalgae. Mangrove leaves, macrophytes, prawns, and fish larvae were found only as supplementary food in all habitats. This was related to the availability of food that varies in each habitat. The catch increased with the discovery of the food habits of mollusks.
