Length-converted catch curves: a powerful tool for fisheries research in the Tropics (III: conclusion)
(1984)Type: Journal ArticleA method is described for the determination of the selection curve of fishing gear from the shape of the ascending arm of a length-converted catch curve and growth parameters. -
Length-converted catch curves: a powerful tool for fisheries research in the Tropics (part 1)
(1983)Type: Journal ArticleA number of methods are available with the help of which total mortality (Z) can be estimated from length-frequency data. Thus it is possible to obtain reasonable estimates of Z from the mean length in a representative ... -
Length-converted catch curves: a powerful tool for fisheries research in the Tropics (part 2)
(1983)Type: Journal ArticleA method is described for the determination of the selection curve of fishing gear from the shape of the ascending arm of a length-converted catch curve and growth parameters. -
Management of multispecies stocks: a review of the theory
(1978)Type: Journal ArticleThe multitude of species contributing to the catch of the demersal fisheries of Southeast Asia, combined with an acute lack of knowledge on the biology of these species and the scarcity of good statistical data on the ... -
Management of tropical coastal fisheries in Asia: an overview of key challenges and opportunities
(1997)Type: Conference ProceedingsCoastal fisheries are an important component of the fisheries sector and rural economy of tropical developing countries in Asia - generating food, employment and foreign exchange. In 1994, marine landings of these countries ... -
MAXIMS: a computer program for estimating the food consumption of fishes from diel stomach contents data and population parameters
(1990)Type: ManualDeveloped for IBM PC (and its compatibles), the software estimates the size-specific daily food consumption of fishes from a 24-hour cycle of stomach contents data for either one or two feeding periods per day, as well ... -
Measuring ecological stress: variations on a theme by R.M. Warwick
(1990)Type: Journal ArticleTwo new indices are presented which reflect quantitatively the changes to be expected in an ecological community under stress, as previously described by R. M. Warwick. The indices summarize information which he presented ... -
Monsoon induced seasonality in the recruitment of Philippine fishes
(1984)Type: Book ChapterThe patterns of recruitment of 112 stocks of Philippine teleost fishes, from 23 families, 34 genera and 57 species, have been studied in detail. The annual recruitment patterns, which were obtained by the backward projection ... -
Ocean sciences in relation to living resources
(1982)Type: Journal ArticleA major new international research program of importance to fisheries is likely to be adopted later this year. Ocean Sciences in Relation to Living Resources, sponsored by FAO and IOC, a proposal concerning the relationship ... -
On holism, reductionism and working from 9 to 5
(1990)Type: Journal ArticleA discussion is presented on the 2 approaches - holism and reductionism - in the study of environmental sciences, making reference to various projects presently being conducted by ICLARM and its collaborators using the ... -
On improving operation and use of the elefan programs. part 1, avoiding "drift" of K towards low values
(1985)Type: Journal ArticleThe article proposes improvements for the ELEFAN programs describing how they may be used for optimum output, considering the von Bertalanffy growth equation and the K parameter. -
On improving operation and use of the elefan programs. part 2, improving the estimation of L
(1986)Type: Journal ArticleFour simple approaches which rely on slightly modified versions of ELEPHAN I and/or II are given for the estimation of length of fish. -
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 Malthusian overfishing
(1990)Type: Journal ArticleA brief examination is made of Malthus' works during the 1800s regarding population growth, considering applications to fisheries resources and their management. -
On microcomputers vs. thinking and their respective roles in fisheries research in developing countries
(1987)Type: Journal ArticleA discussion is presented on the topic of microcomputers and fishery research in developing countries, consideringin particular the advantages of the use of computers for data storage and examination as compared to ... -
On reason, mythologies and natural resource conservation
(1987)Type: Journal ArticleScientific advice is neither generated nor received in a culturally neutral context. There are two ways by which a cultural context can emerge in which conservationists measures are considered reasonable. -
