Abstract For ten years, the Scad fish production in the Northern Coast of Aceh has been increasing rapidly at 172.5%. This condition describes that the Scad fish resource exploitation is implemented under improper management that could encounter an overfishing case. This study aimed to analyze the Scad fish resource utilization level and recommend a management strategy to achieve an optimized Scad fish resource utilization in the Northern Coast of Aceh. This study was performed in the Ocean Fishing Port, Kutaraja, Banda Aceh. Bioeconomic analysis results showed that catching product and effort in MSY condition at 2,838.59 tons and 2,808 trips by economic rent was Rp23,902 million per year. In MEY condition, catching product at 2,748.01 ton with catching effort at 2,311 and economic rent was Rp25,056 million per year. The open-access condition of Scad fish resource with total catching effort at 5,386 trips and economic rent value obtained was Rp 0. Results demonstrated that the Scad fish resource utilization status in the Northern Coast of Aceh encounters biological and economical overfishing. The Scad fish resource management strategy for achieving MSY and MEY condition through input control and output control by establishing the total allowed catching product and catching quota.

AbstractThis paper studies the role of middlemen in open-access fisheries and how the organization of the supply chains affects resource exploitation and the level and distribution of economic rent. Imperfect competition among middlemen can help ensure that fish stocks are not depleted, which is typically the case in open-access fisheries with competitive markets. Middlemen with market power can also induce higher economic rent for the supply chain in total, but these rents mainly benefit the middlemen. The supply chains of inshore anchovy and offshore skipjack tuna fisheries in Vietnam are used as empirical examples. The analysis shows that in the anchovy supply chain, the middlemen have insignificant market power and the stock is being overexploited. In the skipjack tuna supply chain, the middlemen have oligopsony power and the stock is higher than the level that produces maximum sustainable yield.

Indonesia is an Archipelago Country because the Country of Indonesia consists of many islands stretching from Sabang in the west to the island of Merauke on the east. The Archipelago Country also comes from the old name of the Indonesian Country called Nusantara, because Nusantara is a country that consists of many islands. Indonesia is an Archipelago Country which means it has potential resources in the coastal areas, one of which is found on the northern coast of Java. The coastal area is an important area to be reviewed, one of which is the use of coastal resources by paying attention to the condition of the ecosystem that remains stable. Opportunities for coastal area utilization in the field of fisheries are in the form of fishing activities or fish farming, especially pond cultivation activities. Based on data from the Department of Marine and Fisheries of the Province of Central Java in 2010, pond cultivation is one of the potential resources on the coast. This potential is supported by the government to increase fish production in order to increase the consumption of fish in the community. Therefore, it is necessary to choose the most effective method of pond cultivation between traditional methods and intensive methods to optimize fish production. One indicator of effectiveness between the two methods can be seen from the phytoplankton distribution. Phytoplankton contains chlorophyll-a in the body and is a natural food from fish. Phytoplankton provides important ecological functions for the aquatic life cycle by serving as the basis of food webs in water. Phytoplankton also functions as the main food item in freshwater fish culture and seawater fish cultivation. Therefore, it is necessary to know the chlorophyll-a concentration in the ponds of traditional and intensive methods to determine the concentration chlorophyll-a of the two pond methods. One method used to determine the concentration of chlorophyll-a using remote sensing technology. Remote sensing technology can be used to determine the concentration of chlorophyll-a using the Wouthuyzen, Wibowo, Pentury, Much Jisin Arief and Lestari Laksmi algorithms. The results showed that the Pentury algorithm was relatively better to determine the concentration of chlorophyll-a in shallow waters (ponds). The lowest concentration of chlorophyll-a in traditional ponds is 0.47068 mg/m3, the highest concentration is 1.95017 mg/m3 and the average concentration is 1.12893 mg/m3, while in intensive ponds the lowest concentration is 0.36713 mg/m3, the concentration the highest is 3.17063 mg/m3 and the average concentration is 1.53556 mg/m3.

The research is aimed to reveal opportunity development of the capture fisheries in Talaud Islands Regency by using bionomy approach with Gordon-Schaefer model (Fauzy, 2005) con-cerning the dominant of illegal fishing activities around the area. The research was started by co-llected some secondary data on fish production and number of fishing units. Primary data were collected on catch composition and types of fishing gear. Gordon-Schaefer methods was applied to evaluate the tuna and skipjack resources in the area. The troll and pole and line are indicated as the dominant fishing gears used to catch the skipjack and tuna. In case of open access condition, the production will end up to 25,09 tons, while the resource rent will be end up to zero. For the development, simulations were exercised in 3 scenarios: 1) scenario of enhancing domestic fleet, 2) scenario of illegal fishing, and 3) scenario of net surplus. With those scenarios, if the illegal fishing could be eliminated, the capture fisheries in this regency could render economic value to 10 billion rupiah.

A new management strategy for Ontario fisheries was addressed by a federal–provincial task force in 1974–76. It was initiated in an atmosphere of concern over the deteriorating status of fish stocks in Ontario, and indeed elsewhere in Canada. The task force published interim documents on "Goals and Issues," on "Mandates," and on "Objectives." These received limited distribution for criticism. This report summarizes the proposed "Strategy." Speaking generally, it has become abundantly clear that our traditional approach to fisheries management — development-oriented, exploitive, open access — is no longer appropriate in the 1970s and 1980s. That approach, together with the accelerating impacts of land and water uses that conflict with fisheries, has resulted in serious losses in our resource base, particularly during the past two or three decades. A new approach to fisheries management, characterized generally by maintenance in the north and by rehabilitation in the south is now essential. Much of the scientific and technical knowledge needed for the new approach is already available. To apply that knowledge, and to achieve the new knowledge and current data series necessary to its application, a major new initiative is necessary. That initiative, though costly in comparison to past levels of expenditure, seems easily justified in terms of the current economic value of the resources. Furthermore, additional values attributable to fisheries resources are now gaining wide acceptance; e.g. healthy fish communities are indicators of healthy aquatic environments. The new initiative will require more than just funding. It will require the evolution of different value systems, and of new and/or more explicit policies regarding— a new level of public participation;— a "user pays" policy in place of the free access philosophy of the past — to meet some of the increased cost of managing the resource;— more limited access and increased emphasis on protection in place of the open access, common property approach of the past;— explicit recognition that "experimental management" is needed to gain the new knowledge necessary to manage;— recognition that management of fisheries requires greater attention to environmental quality matters;— explicit allocation of those parts of the resource base available for commercial and for recreational use;— new working arrangements between fisheries agencies and other institutions.

Aquaculture Production

India tops the world in aquaculture production next to China. The present Blue Revolution envisages tripling fish production of India by 2020 which necessitates effective resource utilization. The aquaculture resources of a country cannot only be limited to land and water availability but also to its species diversity, workforce and infrastructure facilities. Though Indian aquaculture has registered increased production in past few years, the productivity in terms of water and manpower resources remain very low. There is also a need for diversification of species for mariculture activities. Hence, this paper examines the status of Indian aquaculture from a global perspective to sort out ways for enhancing productivity.

Supply chains are omnipresent. However, the modus operandi of the construction supply chain is not clearly established in the literature. This might be attributable to the character of construction projects and the structure of the construction industry. Formal and informal control mechanisms are well established in retail and manufacturing supply chains whichis evident in improved product performance. However, there is a paucity of research on the construction supply chain especially atidentifying the interplay of control mechanisms and their relationship with project performance. In the case of large and complex construction projects, the client-contractor relationship requires input control, behaviour control and output control for successful project delivery. In the light of organisationcontrol theory and the existing literature on construction supply chains, this study evaluates the modus operandi of the client-contractor relationship based on three control mechanisms: input control (project risk and reward power, and intra-project communication), behaviour control (opportunism) and output control (project performance) using a structural equation model. A survey data of258 construction professionals working on construction projectsin Indiawas collected. The study findingsreveal that input control, in terms of project risk and reward power,and intra-project communication, largely influence behaviour control in terms of opportunism. However, behaviour controls do not directly affect output control in terms of project performance; rather, a direct effect of the input control mechanism of output control is particularly evident.

This study aims to reformulate the institutional relationships between legislative bodies and independent state institutions, by taking case studies of the House of Representatives (DPR) and the Corruption Eradication Commission (KPK). This research was conducted with a normative method using a conceptual and statutory approach. The results showed that the DPR-KPK institutional relationship can be formulated into authority relationship, supervisory relationship and financial relationship. In terms of the authority relationship, the principal-agent approach is used to place DPR as the principal whose duty is to support and provides the resources needed for the KPK as its agent. In this context, the KPK is the recipient of the task whose authority is within the subject of DPR. For the Supervision Relationship, The New Public Management Model (NPM) is used to initiate better supervision through the input and output control mechanism. Input control is carried out by DPR through the legislation and commisoner selection process, while output control is carried out based on accountability reports made by KPK. Thus, DPR is not allowed to intervene while the KPK exercise its duty. In terms of financial relationship, the DPR can regulate funding aspects for KPK through financial legislation. However, this budget politics must be adjusted to the needs and workload in carrying out KPK duties.
