A program for constructing length-converted growth curves when growth is seasonal
Type: Journal Article
Following Sparre's (1990) demonstration that length-converted catch curves overestimate total mortality when growth is seasonal, Pauly (1990) presented a method for constructing length-converted growth curves that allow ...
Time recovery for exploited fish populations based on surplus yield models
Type: Journal Article
A new method to estimate the time recovery of exploited population based on M.B. Schaefer's theory is proposed. The parameters used as follows: current population size (alphaP sub( infinity )'), target population level ...
Concurrent rice-fish trials: comparing regular and border planting patterns
Type: Journal Article
Details are given of experiments conducted at the Freshwater Aquaculture Centre at Munoz, Philippines, to investigate the effects of varying the rice planting pattern on fish yields in integrated rice field aquaculture ...
Demand for fish in Sub-Saharan Africa: the past and the future
Type: Journal Article
The Sub-Saharan region of Africa accounted for only 5.5% of the world's demand for fish from 1989 to 1991, inspite of comprising 9% of the global population. This study was carried out to determine the future demand for ...
MAXIMS: a computer program for estimating the food consumption of fishes from diel stomach contents data and population parameters
Type: Manual
Developed 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 ...
Changes in consumer tastes in the demand for fish and meat in Malaysia
Type: Journal Article
In this article the demand for fish and its substitute was estimated using a very flexible demand function, the Almost Ideal Demand System (AIDS) developed by Deaton and Muelllbaeur (1980), incorporating the habit formation ...
Growth of Pomadasys kaakan (Haemulidae) off the coast of Pakistan
Type: Journal Article
The growth parameters of javelin grunter Pomadasys kaakan (=P. hasta, Haemulidae) were estimated from length-frequency samples collected from December 1988 to February 1989 along the Pakistan coast. They are L sub( infinity ...
Population parameters of Sardinella species in the coastal waters of Dar es Salaam, Tanzania
Type: Journal Article
Population parameters of Sardinella species from the artisanal purse seine and ring net fisheries of the Dar es Salaam area, Tanzania, were investigated based on length-frequency data, analyzed with FAO's LFSA and ICLARM's ...
Exemple de la contribution de l'analyse fsctorielle des correspondences pour suivre l'evolution de la structure d'une population piscicole
Type: Journal Article
This contribution demonstrates an application of correspondence analysis to length-frequency data of catfish (Ictalurus melas, lctaluridae) sampled by electrofishing in the Garonne River, near Toulouse, France. The available ...
International research collaboration in rice-fish research
Type: Journal Article
Growing fish in ricefields could dramatically increase farmers' incomes from rice lands and fish production in Asia. This article describes how collaborative international research can strengthen national research ia ...
