Discounted cash flow techniques, as typically employed in the evaluation of fishery projects, employ constant cost and revenue streams over the duration of the project. The implicit assumption is that additional effort in the fishery does not adversely affect costs and yields. This assumption is...

The parameters a and b of length-weight relationship of the form W = aLêb were computed for 122 species from graphs presented in R.van der Elst's "Guide to the Common Sea Fishes of Southern Africa".

This paper presents a tentative estimate of the parameters L8 and K of the von Bertalanffy growth function, and an estimate of total mortality derived from the analysis, using the ELEFAN I and II programs, of length-frequency data on the snapper Etelis carbunculus (Lutjanidae) collected on...

Growth, total mortality and seasonality of recruitment of male Metapenaeus ensis (Penaeidae) were determined based on length-frequency data (n = 9007) collected in 1988 in the Gulf of Papua, Papua New Guinea.
