Tingginya permintaan tuna sirip kuning baik dalam memenuhi kebutuhan pasar mancanegara dan pasar lokal, berdampak pada keberlanjutan perikanan tuna tersebut. Wilayah perairan Flores Timur adalah salah satu lokasi migrasi bagi tuna sirip kuning; Kecamatan Larantuka merupakan tempat pendaratan terpenting bagi nelayan lokal handline tuna sirip kuning. Kegiatan perikanan tuna sirip kuning ini merupakan salah satu pendapatan utama bagi nelayan lokal dan pemerintah daerah setempat. Penelitian ini bertujuan untuk mengestimasi tingkat eksploitasi dan menganalisa rezim pemanfaatan dari perikanan handline tuna sirip kuning di Larantuka, Flores Timur. Model bioekonomi Fox dan Copes digunakan dalam penelitian untuk menganalisa tingkat lestari sumber daya tuna ekor kuning dari pendekatan input dan output. Hasil estimasi dari kedua model menunjukkan bahwa tingkat pemanfaatan sumber daya ikan tuna sirip kuning oleh nelayan lokal handline masih dalam zona lestari secara ekonomi dan ekologi. Maximum economic yield (MEY) merupakan strategi terbaik untuk mengelola keberlanjutan perikanan tuna sirip kuning di perairan Flores Timur. Melalui pengelolaan rezim MEY diperkirakan dapat menyerap tenaga kerja lebih dari 30 orang, peningkatan armada alat penangkapan sebanyak 25 unit dan pemasukan keuntungan secara ekonomi sebesar Rp68.123.060.000,00 per tahun.Title: Bioeconomic Analysis of Yellowfin Tuna Fishery in Larantuka of East Flores Regency, Indonesia The high demand for yellowfin tuna both in national and international markets has a consequence to the fish resources sustainability. Eastern Flores water is a major area of this tuna mobility; the district of Larantuka is the central port for local yellowfin tuna handline fisheries. These activities are substantial incomes for the local community and regional government. This study, therefore, aims to calculate fish exploitation level and to analyze appropriate management for yellowfin tuna fisheries in Larantuka, East Flores. The bioeconomics Fox and Copes models are used to evaluating the optimal fisheries from input and output approaches. The models’ applications demonstrated that yellowfin tuna handline fisheries are currently estimated sustainable both in ecology and economics. During the study period, the maximum economic yield (MEY) is a recommended strategy to manage yellowfin tuna fisheries in Larantuka, Eastern Flores. The strategy contributes to increasing the number of workers about 30 people, the number of fishing fleets about 25 units and reaching the economic rent  IDR 68.123.060.000,00 in a year

Abstract Fisheries simulation models are tools used for forecasting the effects of exploitation and determining the directions of managing fisheries resources. The Numerical Model of Fish Exploitation (NMFE) and its capabilities were tested on a population of common bream, Abramis brama (L.) in a dam reservoir that is exploited by commercial and recreational fisheries. Based on the designated population parameters of N0, Fij, Mi, and ei and the size and structure of the common bream population in the reservoir, the model was used to examine hypothetical simulation variants of changes in fishing intensity E1 with nets and rods, changes in fishing intensity based on actual fishing effort with nets, changes in natural mortality, changes in the size of fish caught, and the impact of this on the size of the resources. Initial catches with nets and rods were calculated. Increasing fishing effort did not translate proportionally to increased catches, and the function was curvilinear. The results of simulations that reduced the intensity of fishing with nets and decreased catch sizes concurred with data from actual catches. Simulations of changes in natural mortality had various effects on the size of catches. Reducing parameter M did not impact the level of catches, while increasing parameter M reduced the size of catches significantly.

The prehistory of Botswana concerns the sophisticated environmental knowledge, economic strategies, and social networks of the hunter-gatherer, pastoralists, and agropastoralist communities that have called Botswana home. Diverse subsistence strategies and societal structures ranging from heterarchical to hierarchical have coincided and responded flexibly to climate and environmental variables. Botswana has also played a central, but often overlooked, role in precolonial trade within the interior of Africa and across the Indian Ocean. Botswana contains well-preserved archaeological records for the Middle Stone Age, Late Stone Age, and Iron Age periods, including one of the highest concentrations of rock art in the world at Tsodilo Hills. The prehistory of Botswana extends over 100,000 years and includes successful, innovative, and adaptive occupations in a wide variety of environmental zones, from the Okavango Delta to the Kalahari sandveld, and better-watered hardveld areas in the east. Stone Age peoples adapted to both arid and wet lands, and the archaeological record includes early evidence for freshwater fish exploitation. Hunting with bone points dates to 35,000 years ago, with additional evidence for poisonous, reversible arrowheads between 21,000 and 30,000 years ago. Evidence for ritualized behavior through rock paintings, rock carvings, and the intentional destruction and abandonment of stone tools at Tsodilo Hills provides further insights to the social dimensions of early peoples. In the Iron Age, hunter-gatherer communities and agropastoralists participated in a regional and later protoglobal trade across the Indian Ocean for a thousand years before European involvement; as the regional economy intensified, large polities such as Bosutswe and even kingdoms such as the Butua state emerged, controlling access to resources such as game, ivory, salt, specularite, and gold. In the modern era, the historical archaeology of sites such as Old Palapye (Phalatswe) provide additional insight to historical documents that can contradict Eurocentric understandings of Botswana’s past.

New data from the South American lowland tropics are used in support of a recent argument extolling the potential of fish utilization in major floodplains. The discussion will cover five points: (1) major floodplains in general, and the Amazon and Orinoco floodplains in particular, have similar characteristics that make them biologically productive regions; (2) high fish productivity and the use of mass-fishing techniques in floodplain regions are characteristics of lowland South America; (3) the ecological dynamics of the seasonally inundated savanna are particularly productive and propitious for seasonal exploitation using mass-fishing techniques; (4) differences in species composition and fish size may have implications for seasonal and spatial variations in fish exploitation; and (5) substantial biases are apparent against the retrieval of small fish remains using traditional archaeological recovery techniques.

This study aims to describe the adaptive knowledge of Tidung fishermen about the fishing methods. Then, language data is collected through literature study, field observations with in-depth interviews with informants related to all fishing activities of Tidung fishermen. Therefore, data analysis begins with the grouping of data, analysis of domains, grouping categories of types of fishing equipment Tidung fishermen. After that, the data are described in terms of sentences, phrases, words, and are equipped with tables.The results showed that the fishing methods of Tidung fishermen were adaptive following the categorization and ecology of the fish planned to follow natural conditions so that fish exploitation was not excessive.Keywords: fishing, Tidung fishermen, linguistic ecology
