A Removals Limit Algorithm (RLA) is developed to set limits to anthropogenic mortality of small cetacean populations that allow specified conservation objectives to be met.

Summary

In this report, we first describe the framework for developing the RLA in general terms (Section 2) and then go on to describe the development of the population model used for simulation, the form of the RLA itself, the simulation testing framework, the range of simulation tests performed, and the performance metrics used to determine the robustness of the RLA under simulation (Section 3). Section 4 describes the results of the simulation testing to determine robustness. In Section 5, we present an example implementation of the RLA using data for the abundance and bycatch of harbour porpoise in the North Sea. A brief discussion of the work is given in Section 6.
