Journal ArticleDOI
Effect of dietary protein to energy ratio, stocking density and feeding level on performance of Nile tilapia in pond aquaculture
K.A. Kabir,K.A. Kabir,Marc C.J. Verdegem,Johan A.J. Verreth,Michael Phillips,Johan W. Schrama +5 more
TL;DR: Lowering P:E ratio enhanced tilapia production and pond nutrient utilization and economic benefit under two stocking densities and feeding levels in an on-farm trial.
Journal ArticleDOI
Water Flow Affects Zooplankton Feeding by the Scleractinian Coral Galaxea fascicularis on a Polyp and Colony Level
TL;DR: It is demonstrated that water flow affects coral feeding and thus heterotrophic nutrient input at both a polyp and colony level and may serve to optimise coral aquaculture.
Journal ArticleDOI
Integration of Algae to Improve Nitrogenous Waste Management in Recirculating Aquaculture Systems: A Review.
Norulhuda Mohamed Ramli,Norulhuda Mohamed Ramli,Johan A.J. Verreth,Fatimah Md. Yusoff,K. Nurulhuda,Norio Nagao,Marc C.J. Verdegem +6 more
TL;DR: An improved understanding of how to manage the algal reactor and technological advancement of culturing algae will increase the practical and economic feasibility of algal integration in RAS, thus improving the potential of mass cultivation of algae in RAs.
Journal ArticleDOI
Voluntary Feed Intake in Rainbow Trout Is Regulated by Diet-Induced Differences in Oxygen Use
Subramanian Saravanan,Subramanian Saravanan,Inge Geurden,A. Cláudia Figueiredo-Silva,Sadasivam Kaushik,Johan A.J. Verreth,Johan W. Schrama +6 more
TL;DR: In this article, the authors investigated the hypothesis that the voluntary feed intake in fish is regulated by diet-induced differences in oxygen use and found that the intake of trout was regulated by the substitution of fat with starch.
Journal ArticleDOI
Water exchange rate in RAS and dietary inclusion of micro-minerals influence growth, body composition and mineral metabolism in common carp
P. Antony Jesu Prabhu,P. Antony Jesu Prabhu,P. Antony Jesu Prabhu,S.J. Kaushik,Inge Geurden,T. Stouten,Stéphanie Fontagné-Dicharry,Vincent Veron,Catherine Mariojouls,Johan A.J. Verreth,Ep H. Eding,Johan W. Schrama +11 more
TL;DR: Differential regulation in mRNA expression of molecular markers related to micro-mineral uptake, metabolism and oxidative stress were observed in the tissues in response to RAS and premix inclusion, which had multiple effects on the physiology and metabolism of fish on the whole.
