Aquaculture production in Ghana has quadrupled over the past ten years, mainly driven by the development of tilapia culture. Notwithstanding, cultured fish still constitutes less than 10% of national fish production. The sector has a huge potential for growth, especially small to medium scale operators whose productivity has remained very low. It is argued that lack of expansion is due to the high cost of formulated feeds on the Ghanaian market.

This project will build research capacity at KNUST towards state-of-the-art feed development based on locally available ingredients. The nutritional composition and quality of available potential local feed ingredients will be analysed and evaluated, and experimental feed formulations will be developed for testing in farm trials. The research group will include two PhD and three MSc students enrolled at KNUST but jointly supervised by our Danish partners. Knowledge will be transferred nationally through collaboration with farmers and at workshops including key stakeholders, and internationally through publications and conferences.

Utilizing the many potential local ingredients efficiently will not only strengthen the aquaculture sector in Ghana, but also contribute to conserve natural resources through alternative uses. Capacity building in fish feed formulation includes specific knowledge in other disciplines in research and nutritional aspects of agricultural feeds and consequently may strengthen interdisciplinary research within animal nutrition and animal feed formulation.


Midterm report 2016:
The following activities have been completed:
Analyses of macro-nutrients and anti-nutritional factors, and digestibility trials of local agro-by-products (groundnut husk, groundnut cake, cottonseed cake, testing of the effect of pre-treatment on protein, amino acids and anti-nutritional profiles of 6 test diets formulated with different combinations of 5 plant ingredients. Trial of 6 test diets to the identify 2 best performing diets has been completed.
Amino acid profiling of local ingredients completed. Methods for testing nutrient discharges (tanks, cages, ponds) have been established and have tested in tanks. 1st and 2nd MSc students have submitted their thesis and expected to graduate in June 2017. Third MSc. has almost completed his 1st year of studies and has started collecting data for his thesis. Experimental units for the field studies and fish for the field studies are ready. Commercial production of feeds underway to start commercial testing of diets in May 2017. One article has been published and three more are currently under review.
