Use of genetically improved and alien species for aquaculture and conservation of aquatic biodiversity in Africa
Type: Conference Proceedings
Aquaculture species are being domesticated and improved through genetic enhancement. Despite the benefits of improved fish in terms of increased production, there are risks associated with conservation of biodiversity when ...
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.
Size dependent cannibalism in juvenile Nile tilapia (Oreochromis niloticus)
Type: Conference Proceedings
Cannibalism among tilapia fry and fingerlings has been identified as one of the major problems by small-scale hatchery operators (Pantastico et at., 1988). Despite the increasing interest in this species, cannibalism among ...
Policy on the transfer of genetically improved Farm Tilapia (GIFT) from Asia to Africa by the WorldFish Center
Type: Brief
The Mission of The WorldFish Center is to ‘reduce poverty and hunger through improved fisheries and aquaculture’. We work to achieve this through relevant research, development and technology transfer, partnerships, capacity ...
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 ...
A comparison of GIFT and red tilapia for fillet yield and sensory attributes of flesh quality assessed by trained panel
Type: Conference Paper
Tilapia is a tropical freshwater fish, predicted to become the largest aquaculture production in the world, after carps, shrimp and salmonids, in the present century (Fitzsimmons, 2000). In Malaysia 85 per cent of the ...
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 ...
