Aquatic Nutrition


The aquatic animal nutrition facilities are available to any company wishing to benchmark commercially available products or carry out investigative research on new products. The expert team at ABT Innovia will assist in the development of new feed formulations or feeds with specialised novel ingredients providing new approaches to improving aquatic animal growth, reducing environmental impacts or improving health.


A wide range of measured parameters can be built into your required research, allowing a detailed knowledge of the effects of the test substance or process in any life stage of aquatic animal to be gained. 





Feed intake can be measured accurately via hand feeding to satiation, automatic feeding with waste feed collection, set meal feeding, or any method as determined and requested by the client.

Growth performance


Weight specific growth rate (SGR), weight gain, etc. will be measured by recording start, intermediate and final batch or individual weights, as required and specified by the client. Accuracy will be ensured through tight grading prior to trial start, to remove under and over performing animals.

Feed and nutrient utilisation


Feed conversion ratio (FCR) and nutrient retention will be measured using established techniques to high degrees of accuracy and repeatability, making use of accurate feed intake and growth performance data.

Waste Production


Effluent quantification


Determination of digestibility through marker inclusion and detection can be carried out at the request of the client, allowing the modeling of solids production to be carried out.


Effluent characterisation


Detailed effluent characterisation, including particle size distribution (PSD), effluent flow properties, nutrient contents, organics contents, potential environmental impacts, etc. can be determined using a variety of techniques.


Solids removal potential


Information on effluent character can be used to determine effects such as agglomeration or flocculation potential or the efficacy of binders, leading to the ability to estimate the relative removal efficiencies between treatments and the potential reduction of environmental impact from aquaculture.





Survival will be recorded in general or as a specific parameter in trials involving veterinary products, pathogenic or parasitic challenges, etc.


Gastrointestinal effects


The effects of feeds or feed additives on the digestive tract of fish can be determined through detailed microscopic examination, allowing effects of substances such as anti-nutritional factors (ANFs) to be quantified.


Susceptibility to disease or parasitism


Challenge trials will test the susceptibility of aquatic animals to disease or parasite infestation, either after vaccination, application of pre- or pro-biotics, water treatments, etc. Recognised microbiological and identification techniques will identify and quantify pathogens and/or parasites in the laboratory.



Determination of fluctuating asymmetry in early developmental aquatic organisms and Fulton’s condition factor (K) in later stage animals can be analysed to determine the sub lethal and/or non disease related effects of treatments on aquatic animals. 

Product Quality


Flesh quality


Analysis of product marketability in terms of flesh quality as a result of experimental treatments can be determined, to ensure novel feeds and/or additives do not negatively impact marketability.


Presence of off flavours


Experience in the sampling for and analysis of earthy and musty off flavours (geosmin and MIB) in flesh allows these analyses to be offered in addition to flesh quality analysis for marketability assessments.
