This paper provides an outline of a mathematical method to analyse overlapping normal distributions. Separations of mixtures of normal distributions is frequently required in fisheries biological analysis, as in the case of length frequency distribution of fishes. Several methods are available for this. The method presented in this paper was originally developed by V Hasselblad and has been cast in its present form by D Pauly and N David. It was originally published as ICLARM contribution No. 193. The new version, presented in this paper, is written in Microsoft BASIC and can be implemented on a large variety of microcomputers. The specific version presented here can run without modification on an Apple Ile microcomputer (with CP/M-80 operating system). The Program uses up to 12 K of RAM. This paper grew out of a training course on the use of computers in fishery resources management. The course was organized by the project “Marine Fishery Resources Management in the Bay of Bengal” in cooperation with member-countries Sri Lanka, Bangladesh, Indonesia, Malaysia, Thailand and Maldives. Dr. Daniel Pauly of ICLARM and Mr J Hertel-Wulff of BOBP worked on the version presented in this paper. The UNDP-funded project “Marine Fisheries Resources Management in the Bay of Bengal” (RAS/81/051) is a component of the Bay of Bengal Programme (BOBP). It has a duration of four years; it commenced in January 1983. Its immediate objective is to improve the practice of fishery resources assessment among participating countries and to stimulate and assist in joint assessment and management activities between countries sharing fish stocks. This document is a training manual and has not been officially cleared either by the governments concerned or by the FAO. |
