Feed intake, growth and nutrient retention of common sole (Solea solea L.) fed natural prey and an artificial feed

Stephan S.W. Ende, +4 more
- 01 Mar 2016 - 
TL;DR: The low growth in common sole fed the artificial feed was related to lower nutrient and energy intake as well as lower nutrients and energy retention efficiencies, and it is suggested that reduced intake of the artificialFeed might be related to the high dietary fat content of theificial feed.

A first attempt to estimate protein turnover using a simulation model for amino acid metabolism in yolk-sac larvae of Clarias gariepinus (Burchell) and Hippoglossus hippoglossus (L.).

Effects of Stigeoclonium nanum, a freshwater periphytic microalga on water quality in a small-scale recirculating aquaculture system

Norulhuda Mohamed Ramli, +6 more
- 01 Nov 2018 - 
TL;DR: To determine the effect of microalgae on water quality and bacterial composition in a freshwater small-scale RAS, a periphytic microalga, Stigeoclonium nanum, was used and a rapid fingerprint analysis was used to determine the bacterial community composition in the water.
Journal ArticleDOI

Survival of heterophyid metacercaria in common carp (Cyprinus carpio).

A.S. Boerlage, +3 more
- 09 Apr 2013 - 
TL;DR: It was concluded that Heterophyidae may persist in carp for a long time, implying that harvestable carp are a risk to human health.
Journal ArticleDOI

Resistance and resilience of small-scale recirculating aquaculture systems (RAS) with or without algae to pH perturbation.

Norulhuda Mohamed Ramli, +5 more
- 16 Apr 2018 - 
TL;DR: The experimental set-up of this study mimicked recirculating aquaculture systems (RAS) where water quality parameters such as dissolved oxygen, pH, temperature, and turbidity were controlled and wastes produced by fish and feeding were converted to inorganic forms.
