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.

The ringnet fishery off Davao, southern Philippines, is briefly described. The major species (36%) in the catch is Decapterus kurroides (Pisces, Carangidae), whose growth parameters and mortality rates (natural and fishing) are estimated, based on length-frequency data collected in 1985-1986 and...

An application of an algorithm presented by J. Gregor in 1969 for decomposition of a mixture distribution into Gaussian components is presented here in relation to discrete mixture distributions of constant class interval. This graphical separation called Modified Gregor method (MG) uses the...
