(Kenya Marine and Fisheries Research Institute, National Aquaculture Research Development and Training Center,, 2013-06-01)
The effectiveness of sodium bicarbonate as an anaesthetic for Nile tilapia (Oreochromis niloticus) juveniles ranging from 2 to 27g was investigated. The juveniles were exposed to different concentrations of 0 (control), ...
The prospects of biofloc technology (BFT) for sustainable aquaculture development
(Elsevier, 2021)
As capture fishery sector continues to decline, aquaculture industry must be accelerated to
bridge the fish supply gap especially in the developing countries. However, in most devel-
oping countries, aquaculture sector ...
Methane emissions from riverine and swampy coastal wetlands: influence of open and macrophyte‐infested areas
(Blackwell Publishing Ltd, 2011-11)
he atmospheric concentration of methane (CH4) exerts a strong influence on the global climate. Notably, wetlands are important CH4 sources, whose emission represents an ecosystem process depending on such wetland characteristics ...

Survival and avoidance response of the freshwater gastropod Melanoides tuberculatus (Muller) to different concentrations of tobacco waste
(Blackwell Publishing Ltd, 2012-09)
The Gastropod Melanoides tuberculatus plays a significant role in hampering fish larval production in earthen ponds. This study investigated use of tobacco waste to assess behavioural and survival responses of M. tuberculatus ...
A SIMPLE AND LOW-COST TECHNIQUE FOR CULTURING ROTIFERA WITHOUT MICROALGAE
(Ghent University, Belgium, 2017)
So far, microalgae are the first choice diet for feeding rotifers (Maruyama et al., 1997), thanks to their excellent influence on rotifer growth rate (Hagiwara et al., 1997; Dhert et al., 2001; Yoshimatsu and Hossain, ...
