21、 ISO 16488:2015ISO 16488:2015(E)IntroductionThis International Standard is developed to ensure that a net cage marine finfish farms are adequately designed, constructed, and maintained to meet the anticipated rigours of the marine environment in which they will be deployed to prevent escapes (uninte

22、nded impacts) during every day operations and unforeseen events. The standard is to be applied by the farm operators on a site-specific basis. Aquaculture producers are recommended to ensure that the combination of technologies that they have selected for a site meets environmental and other operati

23、onal considerations for that site. Equipment manufacturers can use this International Standard, methodology, and terminology so that their customers (farm operators) can have the opportunity to meet the requirements with this International Standard.The physical rigours of the marine environment to w

24、hich a net cage marine finfish farm can be subjected include tidal currents, wave action, storm surges, hurricanes, wind exposures, icing; equipment design (net cage structures, mooring systems, netting components, predator control, and site markers. Other factors influencing the integrity of a net

25、cage marine finfish farm include qualifications of equipment manufacturers and suppliers, handling practices, inspection and maintenance, reporting and auditing, and stock loss and recovery planning.Within marine aquaculture, an increasing degree of farming on high energy sites (strong tidal current

26、s, wave action, storm surges, hurricanes, wind exposure, icing) is predicted. Further developments in equipment and technology for farming in cages on high energy sites can result in improved water quality and fish health. The use of high energy locations will necessitate improvements of cages, moor

27、ing systems, and feeding systems. It can also require larger boats for servicing, and calls for new techniques for installation and daily operations.This international technical standard is intended to reduce technical and operational failures, consequently enhancing the sustainability of the indust

28、ry. All precautions are recommended to be taken to prevent escapes (unintended impacts) from aquaculture installations as a result of improper specification of technical main components or improper operational use. This International Standard will offer one tool in a link of other guidelines needed

29、for the aquaculture industry to be environmentally sustainable.vi ISO 2015 All rights reservedBS ISO 16488:2015Marine finfish farms Open net cage Design and operation1 ScopeThis International Standard presents a general method to be followed for the systematic analysis, design, and evaluation of net

30、 cage marine finfish farms. One common style of a net cage finfish farm is shown in Figure 1. A mooring system holds together a series of net cages which contain finfish. Water from the outside environment freely passes through the nets, providing the necessary environment for farming finfish. The m

31、ethodology presented in this International Standard allows for determination of the adequacy of a given finfish farms floating structure, nets, and mooring equipment for a given environment. The standard addresses specification of a design basis through evaluation of environmental conditions and acc

32、eptable risk, and specifies acceptable techniques for the design and analysis of finfish farms. This International Standard also provides guidelines for development of a handbook which documents procedures for correct maintenance and operation of the finfish farm.The application of the standard is i

33、ntended to reduce the risk of escape from marine finfish farms. This International Standard is designed to be used by the operator of a net cage marine finfish farm. It is intended that through application of this International Standard that increased human safety and system integrity levels can be

34、achieved.Figure 1 Typical net cage marine finfish farm design2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
