Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
Genetic evaluation of growth and survival at 6 weeks old fry of Egyptian Nile Tilapia (Oreochromis niloticus) between improved Abbassa and commercial Manzala strains in a diallel crossing
Type: Journal Article
The main objectives of this study were to evaluate growth performance and estimate line crossing parameters of improved Abbassa tilapia strain and a commerciall Manzala strain within a complete diallel cross at 6 weeks old ...
Improving feed efficiency in fish using selective breeding: A review
Type: Journal Article
Improving feed efficiency (FE) is key to reducing production costs in aquaculture and to achieving sustainability for the aquaculture industry. Feed costs account for 30-70% of total production costs in aquaculture; much ...
Carp-mola productivity and fish consumption in small-scale homestead aquaculture in Bangladesh
Type: Journal Article
Small indigenous species (SIS) of fish such as the mola carplet (Amblypharyngodon mola) are rich in nutrients, often containing high levels of zinc, iron, and vitamin A. Despite scientific and government efforts, culture ...

Type: Journal Article
Culture of shrimp, mainly Penaeus monodon, makes an important contribution to Bangladeshs aquaculture industry. Shrimp hatcheries are the foundation on which the shrimp industry is built. Hatchery performance and management ...
Effect of dietary protein to energy ratio on performance of nile tilapia and food web enhancement in semi-intensive pond aquaculture
Type: Journal Article
When fish have only access to formulated feed, the optimal dietary protein to energy ratio (P:E) for tilapia ranges between 18 and 23 g.MJ<sup>-1</sup>. In pond culture, where natural foods complement administrated feed, ...
Quantifying the genetic parameters of feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
Improving feed efficiency in fish is crucial at the economic, social and environmental levels with respect to developing a more sustainable aquaculture. The important contribution of genetic improvement to achieve this ...
Detection of Tilapia Lake Virus in Egyptian fish farms experiencing high mortalities in 2015
Type: Journal Article
The aim of this study was to detect potential pathogens in diseased tilapia that might account for the high summer mortalities observed in Egyptian fish farms. To this end, diseased fish were examined from eight farms in ...
Domestic crop booms, livelihood pathways and nested transitions: Charting the implications of Bangladesh's pangasius boom
Type: Journal Article
Rapidly transforming Asian food systems are oriented largely towards domestic markets, yet literature on Asian crop booms deals almost exclusively with commodities produced for export. With reference to pangasius aquaculture ...
