Effects of aerated and non-aerated biofilters on effluent water treatment from a small-scale recirculating aquaculture system for Nile tilapia (Oreochromis niloticus L.)
(Sciendo, 2020-04-21)
Most recirculation aquaculture systems (RAS) use aerated biofilters to maintain suitable water quality for fish production. However, application of non-aerated biofilters may provide opportunities to lower aeration costs, ...
Lifetable demography and population growth of the rotifer Brachionus angularis in Kenya: influence of temperature and food density
(Taylor & Francis, 2016-08-19)
Lifetable demography and reproductive traits of a Kenyan strain of the rotifer Brachionus angularis were investigated using individual and small batch culture approaches. The rotifer was identified morphologically before ...
Aquatic Ecosystem Health & Management
(Michigan State University Press, 2021)
Capture fisheries and aquaculture have remained important sources of food, nutrition, income and
livelihoods to millions globally, with annual per capita consumption of fish in developing countries having
increased from ...
In vitro organic matter disappearance of tanniferous browse using rumen liquid from goats ingesting grass versus browse
(Taylor & Francis, 2013-12-01)
In vitro organic matter disappearance (IVOMD) of African browse species often indicates
artificially low nutritive value due to the presence of condensed tannins (CT). Diet of the
rumen liquor donor may change this if ...
Comparison of net fish yields in pond cultured Nile tilapia (Oreochromis niloticus L.) fed on peanut-based meals as alternatives to dietary fishmeal
(International Journal of Fisheries and Aquatic Studies, 2021)
Although net yield directly relates to actual production at harvest, feeding trials aimed at replacing
dietary fishmeal in cultured fish have largely ignored the performance indicator. A 16-week experiment
aimed at ...
Effects of chicken manure extract on the population growth, mixis induction and body size of the freshwater rotifer Brachionus angularis Gosse 1851
(Asian Fisheries Society, 2015-12-31)
This study investigated the effects of chicken manure extract (CME) on the population growth, mixis induction and body size of the freshwater rotifer Brachionus angularis Gosse 1851. Four concentrations of CME (i.e.0.5, ...
Growth response of rotifers on a bacterial-based diet made from fishwastes
(IOP Publishing, 2019-07)
Fishwastes are potential low-cost diet sources for replacing microalgae, which is the popular diet for rotifers. Growth responses of rotifer were tested under different weights of the diet (i.e. 0.05, 0.1, 0.2 and 0.4 g/L), ...
BLENDING FISHWASTES AND CHICKEN MANURE EXTRACT AS A LOW-COST AND STABLE DIET FOR PLANKTONIC LIVE FOOD PRODUCTION
(Ghent University, Belgium, 2017)
The global increase of aquaculture has expanded the demand for the zooplankton as live foods for larviculture. Although freshly cultured microalgae is the common diet for zooplankton, microalgal culture protocols are ...
Efficiency of pumpkin (Cucurbita pepo), sweet wormwood (Artemisia annua) and amaranth (Amaranthus dubius) in removing nutrients from a smallscale recirculating aquaponic system
(Aquaculture International, 2019-08-28)
In aquaponic systems, plants absorb dissolved nutrients from aquaculture wastewater for their growth. The removal of nutrients allows reuse of water and minimises wastewater discharge to the surrounding environment. This ...
State of aquaculture in Kenya 2021 report
(Kenya Marine and Fisheries Research Institute, 2021)
The report deliberated on the steps being taken to boost and increase aquaculture production in the country.
