A note on the inverse function of the von Bertalanffy growth function
(1990)Type: Journal ArticleParameter estimates of the von Bertalanffy growth function (VBGF) and its inverse function, based on length-at-age and age-at-length data for Tilapia rendalli (Cichlidae) and Salmo trutta (Salmonidae) were derived using a ... -
A trophic ecosystem model of Lake George, Uganda
(1993)Type: Book ChapterA trophic model of Lake George, Uganda, Central Africa was constructed using published quantitative and qualitative information on the various biotic components of the lake and the ECOPATH II approach and software. It is ... -
An ECOPATH II model of the Lake Chad system
(1993)Type: Book ChapterThe trophic ecosystem modelling software, ECOPATH II, was used to analyze the Lake Chad system, Africa, during its "normal" phase, the period between 1969 and 1972. Reasonable estimates of population-related parameters for ... -
Atlas demographique des populations de poissons d'eau douce d'Afrique
(1995)Type: ReportGrowth and catch curves plus recruitment and selection patterns of 57 stocks and 47 species of African freshwater fishes are presented. The atlas also includes mortality estimates, information on food and feeding habits, ... -
Estimation of natural mortality from selection and catch length-frequency data: a modification of Munro's method and application example
(1988)Type: Journal ArticleDetails are given of the modification of Munro's method for the estimation of natural mortality from length-frequency data. An example is given of application of the method using length-frequencies of brown trout (Salmo ... -
Growth, mortality and recruitment of Nile perch Lates niloticus (L. Centropomidae) in the Nyanza Gulf of Lake Victoria: an evaluation update
(2003)Type: Journal ArticleA reassessment of the estimates of growth, mortality and recruitment patterns of Nile Perch, Lates niloticus was made based on data from commercial landings collected during the Catch Assessment Survey Programme. Two sets ... -
Indices of overall growth performance of 100 tilapia (Cichlidae) populations
(1986)Type: Conference PaperFour indices for comparing the overall growth performance of fishes ( omega , P, Phi , and Phi ') proposed by various authors are assessed, based on growth parameter estimates in 100 populations of tilapia in 15 species of the ... -
New functions for the analysis of two-phrase growth of juvenile and adult fishes, with application to Nile perch
(1992)Type: Journal ArticleTwo phases of growth can sometimes be distinguished in long-lived fish species. The first involves the growth of zooplankton-feeding juveniles and young adults. The second consists of accelerated growth of large, piscivorous ... -
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 ... -
Strategic review of enhancements and culture-based fisheries
(2001)Type: Conference PaperEnhancements are interventions in the life cycle of common-pool aquatic resources. Enhancement technologies include culture-based fisheries, habitat modifications, fertilization, feeding and elimination of predat ... -
The general von Bertalanffy growth function: possible use in the Beverton and Holt model
(1985)Type: Journal ArticleUsing the concept of generalized Von Bertalanffy growth formula developed by Pauly and Gasch? tz, we tried to integrate the basic equation of Beverton and Holt and to check on changes in the quantitative evaluation of ...
