Development of high performance marine aquaculture feeds

Development of high performance marine aquaculture feeds: towards the development of a more sustainable and profitable aquaculture sector in Singapore

The Project addresses two of the main constraints limiting aquaculture production within Singapore, namely (1) the lack of technology and knowledge for the implementation of a super-intensive, high density culture system and (2) the absence of local feed manufacturing capability and expertise concerning the production and formulation of super-intensive fish feeds for target species (Sea Bass, Tilapia and Hybrid Grouper).

The Project addresses two of the main constraints limiting aquaculture production within Singapore, namely (1) the lack of technology and knowledge for the implementation of a super-intensive, high density culture system and (2) the absence of local feed manufacturing capability and expertise concerning the production and formulation of super-intensive fish feeds for target species (Sea Bass, Tilapia and Hybrid Grouper).

The Project will be implemented by Blue Aqua International Pte. Ltd. in collaboration with Aquaculture Innovation Center (AIC), and will be addressed in two parts: –

First, the successful remodeling and implementation of a local fish cage farm with a super-intensive culture system using Blue Aqua International’s MixotrophicTM Method of Aquaculture and its protocols.

Second, the research, production and development of super-intensive feed formulations for Sea Bass, Hybrid Grouper and Tilapia. Feed experiments and trials will be performed at Blue Aqua International’s remodeled super-intensive local fish cage farm with goals to achieve a quantum leap in production of the selected cultured species.

Project Objectives:
  • Production and development of cost-effective high quality super-intensive feed formulations for Sea Bass, Hybrid Grouper and Tilapia which have been proven and tested from first feeding to market size under controlled experimental conditions (in collaboration with Temasek Polytechnic);
  • Measurement of the in-vivo apparent nutrient digestibility of all the key feed ingredient sources available to the Singaporean/Asian feed compounder 15 to 20 major feed ingredient sources) for the key target species (Sea Bass, Hybrid Grouper and Tilapia), including apparent digestible coefficients for all essential amino acids, energy, lipid, carbohydrate, phosphorus, magnesium, potassium, and trace elements (in collaboration with Temasek Polytechnic);
  • Production of calibration curves for use with Near Infrared Reflectance spectroscopy (NIR) for each of the major feed ingredient sources tested for each of the target species of the project using the data obtained from the in-vivo apparent nutrient digestibility studies.
  • Successful remodeling of a local fish farm with the integration of MixotrophicTM super-Intensive culture system along with the incorporation of cost-effective super-intensive marine aquaculture feeds to achieve a quantum leap in production of Sea Bass, Hybrid Grouper and Tilapia.
