The aim of this work was to determine those factors, other than abundance, that have influenced the volumes and sizes of fish taken in several specified fisheries, and to initiate an understanding of the mechanisms by which they exert this influence. While a qualitative summary of the factors is useful in understanding these fisheries, the benefit of developing a let of quantitative variables was recognised during the course of the work and the study broadened to include an interpretation of relevant factors as a preliminary to producing a set of quantitative values.
