Meanwhile, based on the results of the analysis of the Mann Whitney test, the calculated z value of -1.878 and the Asympe sig (2 tailed) value of 0.060 The significance probability value is lower than ɑ = 0.05. This means that H0 is rejected and H1 is accepted so that it can be concluded that the sailfin catfish population explosion had an effect on fishermen's income before the sailfin catfish population explosion and after the sailfin catfish population explosion occurred.]]>
