Penelitian berjudul Jenis dan Struktur Trofik Level Ikan di Danau Tempe Kabupaten Soppeng Propinsi Sulawesi Selatan yang dilakukan selama 4 bulan penelitian (Februari, maret, April dan Juni) tahun 2017, bertujuan untuk mengetahui transfer energy di perairan Danau tempe berjalan sesuai dengan sistem jejaring makanan dan manfaat penelitian ini untuk pengelolaan dan pemanfaatan sumber daya ikan yang optimal dan berkelanjutan diperairan Danau Tempe.  Hasil penelitian menujukkan bahwa struktur trifik level Beberapa ikan yang tertangkap di perairan Danau Tempe adalah minimum 2 dan maksimum berfarisasi menurut jenis ikan dan waktu pengamatan.  Disimpulkan bahwa sumberdaya alam diperairan danau tempe berupa fitoplankton dan zooplankton sebagai produser primer dan consumer primer masih mendukung untuk tingkatan trofik diatasnya yaitu ikan South Sulawesi, which was conducted for 4 months of research (February, March, April and June) in 2017, aims to determine the transfer of energy in the waters of Lake Tempe runs according to the food network system and the benefits of this research for optimal and sustainable management and utilization of fish resources. in the waters of Lake Tempe. The results showed that the trific level structure of some fish caught in the waters of Lake Tempe was a minimum of 2 and a maximum of varying according to the type of fish and the time of observation. It was concluded that the natural resources in the waters of Lake Tempe in the form of phytoplankton and zooplankton as primary producers and primary consumers still support the higher trophic levels, namely fish.

Abstract Bangladesh is rich in freshwater fish resources, with 260 indigenous and 13 exotic species. However, fish production from natural resources has declined due to overexploitation and lack of proper management over the last few decades. As a result, many species, including catfish that were once abundantly available, are facing the threat of extinction. Catfish in Bangladesh have potential for aquaculture. There are some 46 species of catfish in Bangladesh but non-availability of stockable-size fry has been identified as a major constraint towards their farming. However, seven species of catfish have been successfully induced to breed to propagate their seed under artificial conditions.

Pengelolaan perikanan tangkap yang lestari membutuhkan informasi potensi dan pola penyebaran sumber daya ikan yang dimanfaatkan. Penelitian ini bertujuan untuk mengetahui distribusi dan potensi sumber daya ikan pelagis di WPP NRI 573 (perairan Samudera Hindia) dengan metode akustik. Hasil penelitian menunjukan, penyebaran densitas cukup tinggi untuk ikan pelagis ditemukan di perairan selatan Pangandaran hingga wilayah Jogjakarta. Sumber daya ikan pelagis kecil yang terdeteksi didominasi oleh ukuran ikan dengan kisaran panjang antara 25-28 cm dan ikan pelagis besar di dominasi oleh ukuran ikan 28-31 cm. Nilai rata-rata kepadatan stok untuk ikan pelagis kecil 0,041 ton/km2 dan ikan pelagis besar sebesar 0,14 ton/ km2. Potensi lestari ikan pelagis kecil sebesar 292.092 ton/tahun dan ikan pelagis besar sebesar 505.941 ton/tahun. Nilai tersebut dapat dijadikan dasar dalam upaya pengelolaan dan pemanfaatan perikanan pelagis.The sustainable management is needed information on the stock and distribution pattern of fish.This study aims to determine distribution and potential of fish resources especially for pelagic species in FMA 573 (Indian Ocean) by using acoustic method. Result of research indicated that, high density for pelagic fish found in south Pangandaran to Jogjakarta. The results obtained also that, the detected small pelagic fish were dominated by the fish size ranged between 25-28 cm and large pelagic fish was dominated by fish size of 28-31cm.The average of the stock density for small pelagic fish was 0,041 ton/km2 and large pelagic fish of 0.14 ton/km2.The sustainable potential of the small pelagic fish amounted to 292.092 ton/year and the large pelagic fish amounted to 505.941 ton/year. These values can be used as the basic management and utilization of pelagic fisheries in the waters region.

A set of resource-functional determinants of sustainable management has been determined, substantiated and formed using the scientific-natural and methodological principles of physical economy. They are represented by various forms of organization, development and transformation of the natural environment in the format of a mega- model of purposeful influence and management of four physiocratic resource bases. They recognized: natural resource processes (material, energy and natural resources); production processes (technological resources); societal processes (information base and social communicative alarm connections); economic processes (organizational and economic resources). The applied tools for determining the order of search, accumulation and involvement of four physiocratic resource bases to ensure and targeted localization of efforts of management entities that take care of key sets of tasks in the field of sustainable management at different levels of management of different dynamic systems. The latter are recognized as territorial natural and economic entities, national and regional socio-economic systems, which currently operate in resource constraints with the ever-increasing socio-political, economic and resource threats and risks to sustainable development of the state and its regions. It is recommended to develop applied tools, permanently refining the sequence of procedures when changing external conditions, through the use of scientific and natural provisions of physical economy, systems theory and turbulence in order to: a) initiate signs of laminarity of four basic processes (economic, social, industrial and natural resource); b) prevention of turbulent shifts. Taking into account the principles of identifying the complexity of the trajectories of the channels and their ability to adjust allowed to establish: the sequence of balancing the turbulent features of the channel of the implementation of processes: natural resources, production, societal, economic, priority of adjustment, first of all, of natural resource and production processes among others.

The purpose of the article is to define an innovative concept of sustainable management based on the analysis of the institutional configuration of business ecosystem entities. The concept of sustainable (SUST) management is outlined as the creation of conditions for multi-entity management of territorial capital on the basis of digital platform technologies and the principles of partnership between government, business and the population. The institutional configuration of territorial business ecosystems is analyzed. It is determined that the business-ecosystem organization of economic activity is a flexible and dynamic system that creates opportunities for the integration of natural resources into economic circulation in territorial communities. It is established that there is a need for a radical restructuring of the institutional configuration of the spatial management system of natural resources in the direction of creating a system of multi-entity management of territorial capital. The main institutions and institutes of the spatial system of natural resources management of the territorial business ecosystem are outlined, in the field of local government, public-private partnership, corporate-platform and structural-project management, etc., within which economic actors of business ecosystems are endowed with appropriate functions and powers.. The structure of the business-ecosystem concept of sustainable management is detailed, including the basic formats of institutionalization of territorial assets management, informational and communicational platform component and management mechanisms of sustainable management, which are focused on creating a system of multi-entity management of sustainable development of territorial communities. Basic formats and forms of institutionalization of territorial assets management in the conditions of decentralization of power are proposed, including communication platforms of collaborative interactions between public authorities, business and population, as well as a set of mechanisms of structural and project management of sustainable development of territorial communities.

Environmental Importance

Over the last 150 years Australia has gained great economic rewards from the use of the natural resources of the Murray-Darling Basin. However, many of the methods used to gain those benefits are now seen as unsustainable. To maintain the region’s productivity in the future, a different approach to managing its natural resources is needed. This paper explains the economic and environmental importance of the Basin, describes the degradation that has occurred, and summarises the efforts being made to achieve sustainable management of the region.
