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 ...
Change and diversity in smallholder rice-fish systems: Recent evidence and policy lessons from Bangladesh
Type: Journal Article
Efforts to unlock the genetic potential of both rice and fish, when combined with improvements in the management of rice-fish systems, can potentially increase agricultural productivity and food security in some of the ...
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 ...
Comparative phylogeography of two monogenean species (Mazocraeidae) on the host of chub mackerel, Scomber japonicus, along the coast of China
Type: Journal Article
In the present paper, the phylogeographies of two monogenean species, Pseudokuhnia minor and Kuhnia scombri, on the same species of host, Scomber japonicus, were studied.
Measurement of haem and total iron in fish, shrimp and prawn using ICP-MS: Implications for dietary iron intake calculations
Type: Journal Article
Twenty-five species of fish, shrimp and prawn from local markets in Bangladesh were analysed for concentrations of total Fe, haem Fe and non-haem Fe by ICP-MS. Total Fe and non-haem Fe concentrations were measured in nitric ...
Spatial Linear Approximate to Almost Ideal Demand System
Type: Journal Article
The paper introduces two spatial systems of demand equation models that are variants of the Linear Approximate to Almost Ideal Demand Systems (LA/AIDS) with habit formation. Specifically, the first model incorporates spatial ...
Population dynamics of Nemipterus japonicus from the northern Arabian Sea, Pakistan
Type: Journal Article
Catch-per-effort and length-frequency data on threadfin bream Nemipterus japonicus (Nemipteridae) supplied by the staff of the R/V Dr. Fridtjof Nansen, covering the period September 1983 to June 1984, were analyzed using ...
A simple method for estimating the food consumption of fish populations from growth data and food conversion experiments
Type: Journal Article
A multiple-regression extension of the basic model is presented which accounts for the impact of factors other than body weight on values of K1 and p. This method is illustrated with an analysis of data on dab (Limanda limianda).
Growth and survival of olive barb, Puntius sarana (Hamilton 1822) larvae produced with cryopreserved versus fresh sperm
Type: Journal Article
Despite the success in fertilization and hatching of fish eggs with cryopreserved sperm, report on growth and survival of larvae produced from frozen-thawed sperm is inadequate. This study evaluates the applicability of ...
Effect of freshwater toxic and non toxic cyanobacteria, (Microcystis aeruginosa) strains on some biochemical parameters of Oreochromis niloticus
Type: Journal Article
This study was planned to determine the grazing rate of O. niloticus from both toxic and non toxic strains of Microcystis aeruginosa with its effect on fish health through study of some clinical signs, hematological and ...
