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.

This article discusses difference between the newly released Compleat ELEFAN Software Packag (Vers. 1.1) (Gayanilo and Pauly 1989, Fishbyte 7(2): 20-21) and its predecessor (Vers 1.0). Also, a number of "bugs" found in Version 1.1 are documented; this led to releaase 1.11 which costs US$75.
