Effect of dietary protein to energy ratio on performance of nile tilapia and food web enhancement in semi-intensive pond aquaculture
(2018)Type: Journal ArticleWhen 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, ... -
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
(2006)Type: Journal ArticleReports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of different ... -
Rhizons improved estimation of nutrient losses because of seepage in aquaculture ponds
(2005)Type: Journal ArticleSeepage represents one of the largest water losses in static ponds accounting for about 30-70% of total pond water losses. This short communication describes a novel method in which a similar principle as in Masuda and ... -
Roles of ponds in integrated agriculture-aquaculture systems
(2007)Type: Book ChapterThe effects of adding an aquaculture pond to existing farming operations on nutrient use efficiency and productivity were explored. Ponds can be used to cycle nutrients from agricultural by-products such as manures and ... -
