The relationship between maximum and asymptotic length in fishes
(1990)Type: Journal ArticleThe case is made, based on growth curves and other data on Kuwait fishes, that the maximum length in a population does not provide a reliable approximation of asymptotic length. -
An empirical comparison of seasonal growth models
(1990)Type: Journal ArticleA model for describing the seasonally oscillating growth of fish is presented and compared with the commonly used model of D. Pauly and G. Gaschutz (PG). The new model produces results similar to those obtained from teh ... -
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 ... -
FISHBASE: an information system to support fisheries and aquaculture research
(1990)Type: Journal ArticleThe International Center for Living Aquatic Resources Management (ICLARM) in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and with the support of the Commission of the European ... -
Water quality research or water quality checking: proposed guidelines
(1990)Type: Journal ArticleA simple plan is outlined to assist in the design of water quality research and monitoring programmes at aquacultureresearch stations. Before monitoring any programme, a decision on the goals of the aquaculture research to ... -
Artificial reefs for marine habitat enhancement in Southeast Asia
(1990)Type: BriefThis study highlights the potential role of artificial reefs in Coastal Resource Management in the ASEAN region. It discusses the considerations necessary to maximize the effectiveness of artificial reefs as a means for ... -
A draft guide to the ECOPATH II program (ver. 1.0)
(1990)Type: ManualThis guide documents the use and background of a program written for MSDOS Computers, in QUICKBASIC 4.5, for straightforward construction and parametrization of steady-state trophic models of aquatic ecosystems. The ECOPATH ... -
Seagrasses: a resource unknown in the ASEAN region
(1990)Type: BriefThe coastal waters of Southeast Asian countries have some of the world's richest ecosystems characterized by extensive coral reefs and dense mangrove forests. The publication provides insights useful towards a better ... -
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 ... -
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 ... -

FISH: Branding guidelines
(2020)Type: ManualThis is a guide to the basic elements that make up the FISH brand. The brand is composed of CRP FISH messaging and visual elements, such as logo, colors, typefaces and photography. Adopting this guidelines will ensure ... -
An assessment of the status of the Ivorian purse seine fishery of Sierra Leone, 1970-78
(1991)Type: Journal ArticleA time series of catch and effort data (1970-78) of the Ivorian purse seine fishery in Sierra Leone waters was analyzed using the Schaefer production model. The regression of C/f on effort was significant and the resulting ... -
Correction to the Beverton and Holt Z-estimator for truncated catch length-frequency distributions
(1991)Type: Journal ArticleA method for estimating the instantaneous mortality rate (Z) is presented which was developed from a truncated equation for average length. The model has zero bias at equilibrium, but has no explicit solution for Z so that ... -
Population dynamics of Saurida elongata and S. undosquamis (Synodontidae) in the southern Gulf of Thailand
(1991)Type: Journal ArticleLength-frequency data on Saurida elongata and S. undosquamis (Synodontidae) from bottom trawl survey conducted in 1984 in the Southern Gulf of Thailand were analyzed using the Compleat ELEFAN software. The seasonal pattern ... -
Bias in the Wetherall estimates of Z/K and L due to population disequilibria
(1991)Type: Journal ArticleThe method of Wetherall (1986, Fishbyte 4(1):12-14) for estimating Z/K and L sub( infinity ) from length-frequency data sampled from a population in equilibrium (constant recruitment and mortality) was examined through ... -
Supply response functions of two fish species in the Arabian Gulf area
(1991)Type: Journal ArticleA polynomial distributed lag model was fitted to monthly fish production data from the Arabian Gulf, Saudi Arabia, inorder to determine the nature of the lagged output response resulting from a change in fish price. Results ... -
Growth of the checkered puffer Sphoeroides testudineus: postscript to papers by Target and Pauly Ingles
(1991)Type: Journal ArticleJ. Ingles and D. Pauly presented at the Fourth International Coral Reef Symposium a seasonally oscillating growth curve for the puffer Sphoeroides testudineus (Tetraodontidae), based on length-frequency data collected in ... -
Exploitation of the dolphin-fish Coryphaena hippurus L. off Ecuador: analysis by length-based virtual population analysis
(1991)Type: Journal ArticleDolphin-fish Coryphaena hippurus in the east Central Pacific are principally exploited by Ecuador. A length-based virtual population analysis of this fishery was sensitive to assumed values of growth parameters in ... -
Training resource book for participatory experimental design: report of a Research Design Workshop on Participatory Design of On-farm Experiments of the ICAR/IRRI Collaborative Rice Research Project
(1991)Type: BookThis book carries on from previous volumes on agro-ecosystem mapping and farming systems diagnosis (see TN2 and TN3).
