Guidelines for the development of environmentally acceptable coastal aquaculture

The paper presents some recommendations for the development of the environmentally acceptable coastal aquaculture such as: 1) Formulate coastal aquaculture development and management plans, 2) Formulate integrated coastal zone management plans, 3) Apply the environmental impact assessment (EIA) process to all major aquaculture proposals, 4) Select suitable sites for coastal aquaculture, 5) Improve the management of aquaculture operations, 6) Assess the capacity of the ecosystem to sustain aquaculture development with minimal ecological change, 7) Establish guidelines governing the use of mangrove wetland for coastal aquaculture, 8) Establish guidelines for the use of bioactive compounds in aquaculture, 9) Assess and evaluate the true consequences of transfers and introductions of exotic organisms, 10) Regulate discharges from land-based aquaculture through the enforcement of effluent standards, 11) Establish control measures for aquaculture products, 12) Increase public awareness of the safety aspects of consuming seafood, 13) Apply incentives and deterrents to reduce environmental degradation from aquaculture activities, and 14) Monitor for ecological change.

Guidelines for environmentally acceptable coastal aquaculture

The article discusses the guidelines for environmentally acceptable aquaculture to ensure that financial gain is not at the expense of the ecosystem or the rest of society. The general principles, strategies and objectives, and action plans for the implementation of environment-friendly aquaculture is also discussed.

Containing the diseases in aquaculture

A brief discussion is presented on epizootics and their containment in the aquaculture industry, in the form of a question-and-answer interview. Particular reference is made to activities carried out by the OIE (Office International des Epizooties), whose main activities include the provision of guidelines and standards for health protection applicable to international trade in live animals and their products. It has devised an early warning system to apprise its member countries of the occurence of disease outbreaks that would have serious repercussions on public health or the economics of animal products.

Guidelines for evaluating the ease of reconfiguration of manufacturing systems

This paper presents guidelines for evaluating the ease of reconfiguration of manufacturing systems. Based reconfigurability measurement tools proposed in the past [1], [2]and a reconfiguration process model, the paper proposes a method that can be used to assess different system characteristics. After the guideline is presented, an example of how the method can be applied to a batch processing system is given. It is found that the proposed method can be applied to batch processing systems based on ISA S88 batch server commercial software. ©2008 IEEE.

Design guidelines for granular particles in a conical centrifugal filter

Essential design criteria for successful drying of granular particles in a conical continuous centrifugal filter are developed in a dimensionless fashion. Four criteria are considered: minimum flow thickness (to ensure sliding bulk flow rather than particulate flow), desaturation position, output dryness and basket failure. The criteria are based on idealised physical models of the machine operation and are written explicitly as functions of the basket size lout, spin velocity Ω and input flow rate of powder Qp. The separation of sucrose crystals from liquid molasses is taken as a case study and the successful regime of potential operating points (lout, Ω) is plotted for a wide range of selected values of flow rate Qp. Analytical expressions are given for minimum and maximum values of the three independent parameters (lout, Ω, Qp) as a function of the slurry and basket properties. The viable operating regime for a conical centrifugal filter is thereby obtained as a function of the slurry and basket properties. © 2012 The Institution of Chemical Engineers.
