Remote sensing and field assessment of tsunami effects on coastal pond aquaculture in northern Sumatra
(2006)Type: Journal ArticleAn attempt was made to conduct spatial assessment of the pattern and extent of damage to coastal aquaculture ponds along the east coast of Aceh province in Sumatra, Indonesia, resulting from the tsunami event of 26 December ... -
Relative Importance of Various Predators in Clarias gariepinus Fry Mortality in Cameroon
(2006)Type: Journal ArticleTo estimate the relative importance of the most common predators of Clarias gariepinus fry, increasing levels of protection were afforded to exclude amphibians, aquatic arthropods and birds. At a stocking density of 10 ... -
Genetic management of aquaculture stocks in sub-Saharan Africa
(2006)Type: ReportThis document is a report of a workshop on genetic resource management in sub-Saharan Africa. -
Community-Based Fish Culture in Seasonal Floodplains
(2006)Type: Book ChapterDuring the rainy season in extensive river floodplains and deltaic lowlands, floods lasting several months render the land unavailable for crop production for several months each year. These waters are considerably ... -
Spatial Linear Approximate to Almost Ideal Demand System
(2006)Type: Journal ArticleThe 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 ... -
A comparison of GIFT and red tilapia for fillet yield and sensory attributes of flesh quality assessed by trained panel
(2006)Type: Conference PaperTilapia 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 ... -
Mass selection for increased body weight at harvest over five generations in silver barb, Puntius gonionotus
(2006)Type: Conference PaperSilver barb (Puntius gonionotus Bleeker 1850) is an Asian carp that is popular as a food fish. It is distributed throughout Thailand in rivers, canals, reservoirs and swamps. It is also cultured in ponds and paddy fields. ... -
Experimental evaluation of co-culture of juvenile sea cucumbers, Holothuria scabra (Jaeger), with juvenile blue shrimp, Litopenaeus stylirostris (Stimpson).
(2006)Type: Journal ArticleThe co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or ‘sandfish’, with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in ... -
Improving productivity in tropical lakes and reservoirs
(2006)Type: ReportIn this review we will discuss the potential for increasing production within natural lakes or manmade reservoirs based on the various enhancement concepts. Enhancements are interventions in natural aquatic resources, and ... -
Restocking and stock enhancement of coastal fisheries: Potential, problems and progress
(2006)Type: Journal ArticleThe demand for fish is expected to rise substantially by 2020. Although aquaculture must provide much of the additional fish, it remains to be seen whether restored or enhanced capture fisheries can also help fill the ... -
Nile tilapia (Oreochromis niloticus) seed production in irrigated rice-fields in Northwest Bangladesh-an approach appropriate for poorer farmers?
(2006)Type: Journal ArticleParticipatory 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 ... -
Comparison of aquaculture extension impacts in Bangladesh
(2006)Type: Journal ArticleProduction from small scale pond aquaculture in Bangladesh trebled in the decade to 1999 under the influence of extension projects of the Department of Fisheries. The impacts of completed aquaculture extension projects and ... -
Global documentation of fish introductions: the growing crisis and recommendations for action.
(2006)Type: Journal ArticleFish provides 15% of the total animal protein in human diets. It is also the primary source of livelihood for 35 million people (30 M in Asia and 2.6 M in Africa). The increase in global population and demand for fish ... -
Water management and wise use of wetlands: enhancing productivity
(2006)Type: Book ChapterLakes and reservoirs are affected by human interventions mainly by eutrophication. Changes in morphology are less common, although siltation and local alterations to the riparian zone can result from urbanisation,marina ... -
Genetic and environmental factors affecting growth of Nile tilapia (Oreochromis niloticus) juveniles: Modelling spatial correlations between hapas
(2006)Type: Journal ArticleThe aim of this study was to quantify the environmental and genetic effects on early growth of Nile tilapia, Oreochromis niloticus. -
Survival of Clarias gariepinus fry in earthern ponds: effects of composts and leaks
(2006)Type: Journal ArticleTo inform decisions on improving the yields of African catfish Clarias gariepinus fingerlings in earthen ponds, the hypothesis that composts and leaks were partly responsible for usually low and variable fry survivals was ... -
Advanced nursing of Clarias gariepinus (Burchell, 1822) fingerlings in earthen ponds, through recycling of tilapia recruits
(2006)Type: Journal ArticleIn an attempt to improve the stocking size and yield of Clarias gariepinus, small fingerlings (average weight=3 g) of the type usually produced by African hatcheries were stocked together with tilapia (Oreochromis niloticus) ... -
Effect of varying density and water level on the spawning response of African catfish Clarias gariepinus: Implications for seed production
(2006)Type: Journal ArticleThe development of a reliable methodology for spawning of African catfish, Clarias gariepinus without the use of hormone injections would greatly improve the prospects of aquaculture in Africa. Earlier work has shown that ... -
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
(2006)Type: Journal ArticleThis study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
