Production of juvenile wrasse

Recently there has been a growing interest in farming of wrasse. The species that are most relevant for farming is ballan wrasse, but other species may also be relevant.

Fry of ballan wrasse are poorly developed at hatching, and need live zooplankton as feed the first period. SINTEF Fisheries and Aquaculture has worked for many years with various types of plankton (rotifers, Artemia and copepods). Good and stable quality of the plankton is essential for good growth and survival.

Wrasse larvae require relatively high water temperatures. Recycling solutions that ensures stable temperature and a good water quality (microbially stable) can be an important contributory factor to achieve solid growth and survival.

We also work with sorting and transport of fry and smolt. This is an important contribution to industrial production of wrasse.
