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.

The software will no longer run on typical PC’s, however, the algorithms are specified in the paper to facilitate coding in Python, R, Matlab etc. Halmar Halide, A. Stigebrandt, M. Rehbein, and A.D.

背景概述

该数据集为网箱养殖决策支持工具（CADS_TOOL），包含场地分类、场地选择、养殖容量和经济评估四个核心模块，旨在辅助海水和淡水网箱养殖管理者进行可持续养殖决策。由于工具年代久远，已不再获得官方支持，但算法细节已公开，便于用户通过Python、R等编程语言重新实现。
