During the past one decade, the WorldFish Center and its research partners have made a systematic attempt to improve the productivity of carps through selective breeding in the major carp-producing countries in Asia. This paper analyses the potential impact of culturing the improved carp strain...

This study examines the dynamic relationship between wholesale and retail prices of beef products, accounting for product differentiation in cuts and quality grades. We test for long-run association in price transmission relationship in presence of asymmetry caused by threshold-type adjustments....

This paper addresses the issue of competition in the U.S. catfish industry. To this end, a conjectural variation oligopolistic model was developed. The model was estimated econometrically using the Generalized Method of Moments (GMM) procedure. Chi-square analysis implied that catfish processors...

Cost efficiency measures of a sample of catfish farms in Chicot County, Arkansas are estimated using a data envelopment analysis technique. A measure of overall efficiency is used to determine operator's characteristics, farm practices, and institutional support services that are likely to lead...

Under a particular representation of the impact pathway of natural resource management (NRM) research, economic surplus techniques can also be used for ex ante impact assessment. The method is applied to the case of the WorldFish Center, an international organization specializing in research on...

Seasonal floodplains under private and public ownership in the Indo-Ganges river basin provide food and income for millions of people in Bangladesh. Floodplain ownership regimes are diverse, covering the whole spectrum from public to private ownership. The paper compares community-based fish...

Sustainable agricultural intensification is an urgent challenge for Sub-Saharan Africa. One potential solution is to rely on local farmers' knowledge for improved management of diverse on-farm resources and integration among various farm enterprises. In this article, we analyze the farm-level...

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 poorest and most populous countries in Asia. In Bangladesh, estimates...
