Classification-tree analysis evaluating stay and exit decisions in the studied fisheries in response to a hypothetical halving of catch value.

Based on the responses of 599 Western Indian Ocean fishers. Splits were based potentially on all variables described in Table 1. Sites are coloured by country (Blue – Seychelles, Green – Mauritius, Purple – Tanzania, Black – Kenya, Red – Madagascar). Numbers of fishers opting to stay (left) and exit (right) are shown at each branch. Fishers meeting the split conditions [e.g. material style of life (MSL)

本数据集基于599名西印度洋渔民的调研应答数据。样本划分依据可能采用表1中描述的全部变量。各站点按所属国家配色：蓝色对应塞舌尔，绿色对应毛里求斯，紫色对应坦桑尼亚，黑色对应肯尼亚，红色对应马达加斯加。每个分支处均标注了选择留守（左侧）与退出（右侧）的渔民人数。符合划分条件的渔民[例如物质生活方式（Material Style of Life, MSL）
