Some definitions of overfishing relevant to coastal zone management in Southeast Asia
(1988)Type: Journal ArticleThis essay is an attempt to define overfishing in terms less technical than those generally used by fishery biologists. It started from the classical definition, then quickly moved on to concepts that may be more relevant ... -
Role of tilapia (Oreochromis andersonii) in integrated farming systems in Zambia
(1988)Type: Conference ProceedingsThe old system of cultivating several species of tilapia together in the same pond has been changed to monospecies culture. Oreochromis andersonii has been shown to yield good growth and production rates. A broodstock ... -
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 ... -
Reporting fishpond yields to farmers
(1988)Type: Journal ArticleThe frustrations encountered when trying to compare technical reports in which fishpond yield figures are reported in a variety of units (e.g., kg/ha, kg/pond, lb/acre, etc.) are familiar to most aquaculturists. However, ... -
Genetic considerations on acquisition and maintenance of reference populations of tilapia
(1988)Type: Journal ArticleThe maintenance of reference populations of Tilapia is discussed, examining genetic considerations to be taken into account to conserve the gene pool to prevent genetic drift and prevent detrimental levels of inbreeding. ... -

(1988)Type: ReportThe Small Pelagic Management project was established in the Philippines to conduct a review of Philippine small pelagic fisheries and to conduct stock assessment and economic analyses on these fisheries. Growth, mortality ... -
Ressources genetiques en tilapias pour l'aquaculture
(1989)Type: Conference ProceedingsTilapia culture in Asia and other non African countries is practiced on a narrow genetic base. In contrast, African countries, many of which need assistance to develop their own aquaculture sectors, hold the global wealth ... -
Estimation and comparison of fish growth parameters from pond experiments: a spreadsheet solution
(1988)Type: ManualA method is presented to estimate and compare the growth of fish in pond experiments using a Gulland/Holt plot. The method is implemented as a LOTUS 1-2-3 "spreadsheet" allowing easy data editing and analysis. An example ... -

(1989)Type: BriefGives comprehensive and well-illustrated techniques in comics format for establishing and maintaining an inexpensive hatchery for common carp, based on the techniques adopted in the common carp culture in Indonesia. -
Notes on the assessment of the stocks of small pelagic species on the basis of length frequency analysis and converted catch curves
(1988)Type: Journal ArticleDifficulties are usually encountered when small pelagic species are to be assessed, using simple classical methods such as the surplus production model. Interannual variations of recruitment and fishing patterns and ... -
