Abstract: The Indonesian state forest managers have accepted farmer-managed coffee agroforestry in their estates as part of their social forestry program. Access by local farming communities to state-owned plantation forestry supports public motivation to maintain forest cover. However, balancing the expectations and needs of forest managers with those of the local farming communities is not easy. Coffee yields in Indonesia are lower than those of neighboring countries, suggesting that there is scope for improvement. Here we describe an experimental research platform developed through an international collaboration between the Universitas Brawijaya (UB), the UK Centre for Ecology and Hydrology (UKCEH), and smallholder coffee farmers to explore options for improving pine-coffee agroforestry systems within existing regulations. Located in a former state-owned pine production forest on the slopes of the stratovolcano, Mount Arjuna, in the Malang Regency of East Java, the research platform has seven instrumented research plots (40 × 60 m2), where agronomic practices can be trialed. The aim of the platform is to support the development of sustainable agronomic practices to improve the profitability of coffee agroforestry and thus the livelihood of low-income rural communities. Current trials are focused on improving coffee yields and include pine canopy trimming, fertilizers, and coffee pruning trials, with links to the development of socio-economic and environmental models. Whilst it is too early to assess the full impacts on yields, a survey of farmers demonstrated a positive attitude to canopy pruning, although with some concern over labor cost. The initial ecosystem modelling has highlighted the benefits of coffee agroforestry in balancing environmental and economic benefits. Here we provide a detailed description of the site, the current trials, and the modelling work, with the hope of highlighting opportunities for future collaboration and innovation.

Abstract: Lobster fisheries play an important role in the development of Indonesian fisheries management. The tropical lobster genus Panulirus has high species ersity in the Indonesian Eastern Indian Ocean. The Indonesian government has designated lobster fisheries as one of the types of fisheries requiring special attention in 11 of the Fisheries Management Areas in the Republic of Indonesia (FMARI). Each management area has specific ecological characteristics and may have unique lobster species richness. Studies on the temporal and spatial distribution of lobster species during all life phases are necessary to determine the connectivity of lobster populations. This study aimed to identify the species of lobster larvae of the genus Panulirus in FMARI 573. S les were collected from several locations, including Pacitan, Trenggalek, Tulungagung, Banyuwangi, and Lombok, in July-August 2018. Data were analysed descriptively through species identification based on morphological traits. Identification of the s les was carried out at the s ling site and in the laboratory. The study found six species of lobster larvae: Panulirus ornatus (local name udang mutiara ), P. homarus ( udang pasir ), P. penicillatus ( udang batu ), P. versicolor ( udang bambu ), P. longipes ( udang batik ) and P. polyphagus ( udang Pakistan ). These species were unevenly distributed at the study sites. Further research is needed to analyse the distribution and connectivity of lobster populations by analysing species composition during different life phases (larva uerulus, juvenile, adult) at different spatial and temporal scales.

Abstract: Lobster is an important economic fishery resource in domestic and international trade. The high economic value of lobster due to increasing market demand has led to its intensive exploitation. The enactment of specific regulations on lobster proves the urgency of its management. Madura Strait is one of the unique biogeographical sea regions of East Java. This research was conducted in January-March 2021 at Pasir Hitam Beach, Situbondo. The purpose of this study was to determine the species composition of lobsters, the frequency distribution and the growth form, and the sex ratio. The analysis applied is class distribution of length and weight classes, regression analysis, and chi-square. The lobster catches consist of 4 species, namely Scalloped spiny lobster ( Panulirus homarus ), Ornate spiny lobster ( P. ornatus ), Painted spiny lobster ( P. versicolor ), and Mud spiny lobster ( P. polyphagus ). P. homarus is the most dominant species. The frequency distribution of carapace length and weight of P. homarus, P. ornatus , and P. versicolor has met the minimum size limits rules. The length and weight relationship of P. Homarus and P. ornatus were negative allometric, while P. versicolor isometric. Lobster sex ratio is in a balanced condition.

Abstract: Indonesia is the largest archipelagic state with mixture oceanography lead to bio geographical ersity. Information of the distribution of marine organisms is necessary for their management. The national fisheries management authority of the Republic of Indonesian has set East Java Province in 2 management areas, namely WPPNRI 712 in the North (Java Sea) and WPPNRI 573 in the South (Indian Ocean). Pacitan regency lies at the South Sea of East Java and known as one regency with the highest lobster production in the region. One of the priority fishery groups in the management is a lobster fishery. Lobster is known as a fishery commodity with a very high economic, social and ecological value. This study aims to identify species composition of lobster caught in Pacitan’s waters. The study will be fundamental information for connectivity study of the lobster in the region. Data was based on lobster catch from local fisher. Data collection was carried out in T eran, Pacitan regency of East Java. Data analysis was performed using ANOVA test. There are six species lobster found. Dominant lobster species are Panulirushomarus (Pasir), followed by P. penicillatus (Batu), P. versicolor (Bambu), P. longipes (Batik), P. ornatus (Mutiara), and the least dominant is P. polyphagus (Pakistan).

Abstract: Species ersity is prevalent throughout Indonesia’s Coral Triangle areas. A fisheries management area has been set over its archipelagic waters ensuring the sustainability of the resources. Six species spiny lobster of Panulirus are known to live in Indonesia archipelagic waters. They have a significant contribution to the country. A study on the distribution variation of the marine organisms through the life phase in space and time is critical information for its management. Therefore, a similar study was conducted for the lobster population along the South Sea of Java of Eastern Indian Ocean. The purpose of this activity was to develop formulations to protect ecosystems and conserve lobster resources. Distribution of pueruli larvae of spiny lobster of Panulirus species was surveyed in Banyuwangi, East Java from February to March 2019. The number of pueruli larvae caught were counted and compared among the species. Data analysis was executed using the ANOVA test. There were four species of lobsters found. Dominant species were Panulirus homarus (Scalloped spiny lobster), P. pennicillatus (Pronghorn spiny lobster), P. versicolor (Painted spiny lobster) and P. ornatus (Ornate spiny lobster). Life history distribution of the species may support connectivity hypotheses of the lobster population in the region.

Abstract: There are about six species of tropical spiny lobsters within a group of Panulirus inhabit Indonesia archipelagic waters. A lobster fishery is among relevant national fisheries products. Their social, economic, and ecological contributions to the country are significant. Hence, the lobster’s resource sustainable use always becomes a challenge for the management authority. Life phase distribution of marine organisms in space and time is critical information for management. The equivalent study can be phrased for the lobster population in the South Sea of Java Island of Eastern Indian Ocean. The purpose of this study was to develop formulations to protect ecosystems and conserve lobster resources. Distribution of pueruli larvae of spiny lobster of Panulirus species was surveyed in the South Sea of Pacitan, East Java from January to February 2019. The number of pueruli larvae caught were counted and compared among the species. An ANOVA test was performed for data analysis. There were four species of lobster found. The dominant species was Panulirus homarus (Scalloped spiny lobster). It was followed by P. versicolor (Painted spiny lobster), and P. ornatus (Ornate spiny lobster). The least dominant was P. pennicillatus (Pronghorn spiny lobster). Comparative study on life stage distribution concerning to larval dispersal may support the connectivity hypotheses of the lobster population in the region.

Abstract: Abstract. Setyanto A, Sumarno, Wiadnya DGR, Prayogo C, Kusuma Z, West RJ, Tsamenyi M. 2023. Fishing methods and fishing season of the tropical lobster fisheries of southern Java, Indonesia. Bio ersitas 24: 778-783. Tropical lobster fisheries represent a relatively small-scale but valuable export industry in Indonesia, but in many ways may fall within the category of Illegal, Unreported and Unregulated (IUU) fisheries. The absence of useful fisheries information means the management strategies and plans to manage the fisheries is severely limited. This research aimed to provide information about the fishing gear, methods, and fishing season of the fisheries, as a precursor to the development of fisheries management strategies. The study was conducted at Watukarung, Pacitan (East Java) and Baron, Gunungkidul (Yogyakarta). Fisheries data on lobster catch, fishing methods and fishing effort were collected through direct observation and interviews with fishers, fishery officers and port managers. Catch data were analyzed using ordinations technique to determine the fishing season. Lobsters were captured in various fishing gears throughout the year, but fishers targeting lobsters primarily used specialized lobster nets deployed by small boats and “krendet” (traps) deployed from clifftops as well as from small boat. The main fishing season for lobsters was from November to February each year. Future research needs to investigate fishing capacity and population parameters before any comprehensive fisheries management can be undertaken.
