Comments Authors recommend discarding 1964 and 1965 (CPUE is probably an overestimate due to the inaccurate recording of effort data in those years (in Figure 5: caption)). Time-series represents group: Pristis pristis, P. zijsron. Time-series could represent P. zijsron as this species was the most abundant in catch (see supplementary of the publication). 0s between 2012 and 2020 were added as no sawfish species was caught since the end of the time-series from the publciation (2020 pers. comm. Matt Dicken, Chief scientist at KwaZulu-Natal Sharks Board)
