A Cage Aquaculture Decision Support Tool (CADS_TOOL)

This tool consists of four modules: Site Classification, Site Selection, Holding Capacity and Economic Appraisal. The first two modules, Site Classification and Site Selection modules are linked and result in an assessment of the suitability of a particular site for cage aquaculture.The four modules are:1. Site Classification - allows a site to be classified into three suitability categories (Poor, Medium or Good) based on water quality, substrate quality, hydrometeorology and socioeconomics parameters.2. Site Selection - incorporates scores from the Site Classification module. User defined weights (index of relative importance) are assigned to the criteria in the Site Classification module and the overall suitability of the site is calculated.3. Holding Capacity - allows for the calculation of holding or carrying capacity based on four different models. For marine cages, the methods available are: Simplified MOM based on Stigebrandt et al (2004), Tookwinas et al (2004) and Hanafi et al (2006). Palatsu et al (2003) is used for freshwater cages in lakes/dams.4. Economic Appraisal - allows for the calculation of a break-even price and return on investment.The Cage Aquaculture Decision Support Tool was developed to allow marine and freshwater cage aquaculture managers to:1. classify a site2. select the best site from several site alternatives3. calculate the sustainable holding density of a chosen site and4. perform a basic economic appraisal of a farm at that site.Calculation methods for marine cages:Hanafi, A., Andriyanto, W., Syahidah, D., Sukresno, B. 2006.

本工具包含四大模块：场地分类（Site Classification）、场地选址（Site Selection）、养殖容纳量测算（Holding Capacity）与经济评价（Economic Appraisal）。其中前两个模块相互关联，可评估特定场地是否适合网箱养殖。四大模块详情如下：
1. 场地分类模块：可依据水质、底质、水文气象及社会经济参数，将场地划分为三类适宜等级：差（Poor）、中（Medium）、优（Good）。
2. 场地选址模块：整合场地分类模块的评分结果。用户可自定义各分类标准的权重（相对重要性指数），并据此计算场地的综合适宜性。
3. 养殖容纳量测算模块：可基于四种不同模型测算养殖容纳量。针对海水网箱，可用方法包括基于Stigebrandt等人（2004）、Tookwinas等人（2004）及Hanafi等人（2006）研究的简化MOM（Simplified MOM）模型；针对湖泊/水库中的淡水网箱，则采用Palatsu等人（2003）提出的模型。
4. 经济评价模块：可测算盈亏平衡价格与投资回报率。

本网箱养殖决策支持工具旨在为海水及淡水网箱养殖管理者提供以下支持：
1. 开展场地分类
2. 从多个候选场地中选出最优场址
3. 测算选定场地的可持续养殖密度
4. 对该场址的养殖场开展基础经济评价

由于年代久远，澳大利亚海洋科学研究所（AIMS）已不再维护CADS TOOL，该软件无法在当前主流个人电脑上运行，但其算法已在论文中详述，便于在Python、R、Matlab等环境中进行代码开发。
