On China's lake fisheries development
(1991)Type: Journal ArticleAn account is given of the current situation regarding the lake fisheries and fish culture practices in China. The modern lake fisheries take advantage of the 3-D spaces of lakes to fully develop the resources. Currently, ... -
On comparing groups of fishes based on length-weight relationships
(1993)Type: Journal ArticleF. Torres, Jr., in a 1991 Fishbyte article, presented length-weight relationships derived from 122 graphs in van der Elst's 1981 "A guide to the common sea fishes of southern Africa". This author analyzes Torres's tabulated ... -

On improving operation and use of the elefan programs. part 3, correcting length-frequency data for the effects of gear selection and/or incomplete recruitment
(1986)Type: Journal ArticleOne important feature of length€”frequency data that is usually ignored when data are collected for subsequent estimation of growth and various related parameter estimates is that length€”frequency data are necessarily ... -
On improving the resolution of the recruitment patterns of fishes
(1991)Type: Journal ArticleIt is proposed that the "recruitment pattern" routine of the ELEFAN II program can be modified to allow, in addition to length-frequency data, the use of "restructured" data files. An example, based on Oreochromis niloticus ... -
On length-weight relationships. Part I: Computing the mean weights of the fish in a given length class
(1987)Type: Journal ArticleWhen working with length frequency date, we often need to compute the mean weights of the fish in the various classes. This article outlines one of the methods used. -
On length-weight relationships. Part II: Computing mean weights from length statistics
(1991)Type: Journal ArticleAssuming a known length-weight relationship, the formula for calculating the mean weight from grouped length statistics is recapitulated. Then a simple analytical method for calculating mean weight from basic length ... -
