From drawing board to dining table: the success story of the GIFT project
Type: Journal Article
As compared to crops and livestock, the genetic enhancement of fish is in its infancy. While significant progress has been achieved in the genetic improvement of temperate fish such as salmonids, no efforts were made until ...
Socioeconomics of disseminating genetically improved Nile tilapia in Asia: an introduction
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM) undertook a major strategic research project known as the "Genetic Improvement of Farmed Tilapias" (GIFT), with funding support from the United ...
Impacts of organic fertilization systems on water quality, phytoplankton populations and fish production in earthen ponds
Type: Journal Article
This study carried out to evaluate the influence of two application system of chicken manure fertilizer in earthen ponds on water quality, phytoplankton population and fish production.
Heritability of cold tolerance in Nile tilapia, Oreochromis niloticus juveniles
Type: Journal Article
The inability of tilapia to tolerate low temperatures is of major economic concern as it reduces their growing season and leads to over winter mortality. In this study, cold tolerance of juvenile Nile tilapia, Oreochromis ...
Technical efficiency of tilapia growout pond operations in the Philippines
Type: Journal Article
The determination of efficient production levels for tilapia growout operations, given the existing technology, is necessary to examine alternative options to increase productivity. If farmers are not making efficient use ...
Nile tilapia (Oreochromis niloticus) seed production in irrigated rice-fields in Northwest Bangladesh-an approach appropriate for poorer farmers?
Type: Journal Article
Participatory research was conducted with poorer farmers in two communities, Girai (G) and Bahagili (B) in NW Bangladesh to assess the production of Nile tilapia seed in irrigated spring rice-fields. All the selected ...
Tilapia broodstock development for saline waters in the Philippines
Type: Journal Article
Four Oreochromis species were used in the study. Progenies from the 27 cross combinations (5 pure breds and 22 crossbreds) were evaluated in 10 environments with different salinity levels and agro-climatic conditions using ...
Impact of Saturn herbicide on histological structures and residual aspects of Nile tilapia (Oreachromis niloticus)
Type: Journal Article
This investigation was performed to demonstrate the effect of Saturn herbicide on Nile tilapia (Oreachromis niloticus). Experimental studies were done to determine of LC50 of Saturn and evaluate its acute and chronic ...
