Marine algae as a novel, sustainable organic supplement in fish feed for salmonid aquaculture.

Dr Suzan Coughlan (Post Doc) and Anna Soler Vila (PhD) Project partially takes place in the ISC and at the Carna Marine Laboratories of the MRI (2002-2005). Funded by the HEA Ireland

The initial phase of this project will build research capacity by establishing nutritive value and overall suitability of a range of seaweeds as supplement in fish feed for salmonid aquaculture with a resulting increase in demand, either from natural sustainable or cultivated renewable sources, and contribute to the economy and maintenance of coastal communities in peripheral areas and rural development. Marine algae could potentially replace several components in conventional fish feed to provide an organic fish feed and cut down on the use of fish meal, one of the priorities of the EU fisheries policy. The basic research in this project  will initiate future applied research in aquaculture, which is of direct relevance to the Marine Institute Research programmes.

The work will involve:

1)       Biochemical component analysis of several common algae, seasonally, to produce reliable data on the nutritional components of Irish seaweeds.

2)       Explore the possibility to cultivate certain algae in tank cultivation as a renewable source.

3)       Explore the usefulness of seaweeds as a feed additive for salmonids. For this purpose feed trials will be preformed with different percentages and different seaweeds in the feed.
