Integrated multi-trophic aquaculture systems: a solution for sustainability

Marine aquaculture of high value species such as fish is generally reliant on external food supplies and has a negative impact on water quality, generating high organic and nutrient loadings. Integrated multi-trophic aquaculture offers a solution to reduce environmental impact of farming systems, culturing complimentary species that can recycle nutrients and reduce nutrient pollution while generating additional products for sale. This article looks at species selection and integration of trophic levels in system design.

Production of tubifex - a new dimension of aquaculture in feeding juvenile fish

The use of sludge or ‘tubifex’ worm, Tubifex tubifex, as a live food for juvenile fish has been long practiced in farmers’ fields and it is an important fish food for spawn rearing. The cost of tubifex worm becomes prohibitive in the dry season, when supplies are limited. We conducted trials to test the feasibility of culturing tubifex using a selection of agro-industrial wastes. Net biomass production was highest using rice mill sludge as a food source, over a culture period of 20 days.
