Effect of dietary inclusion of dried Tetraselmis suecica on growth, feed utilisation and fillet composition of European sea bass juveniles.
Several marine microalgal species offer a valuable source of long chain PUFA’s that have the potential to become a sustainable alternative dietary source and therefore may help to meet the increasing demand for fish oil that is a critical limiting factor for the future expansion of aquaculture activ...

Several marine microalgal species offer a valuable source of long chain PUFA’s that have the potential to become a sustainable alternative dietary source and therefore may help to meet the increasing demand for fish oil that is a critical limiting factor for the future expansion of aquaculture activities. Oil extracted from the algae have proven to successfully replace marine fish oil in diets for Atlantic salmon or sea bream (Miller et al., 2007; Ganuza et al., 2008). Microalgae may also offer much potential as sources of protein, bio-active compounds, antioxidant and vitamins to supplement the diet of high-value fish species or in organic-based aquaculture systems. Significant advances have recently been made in the field of photobioreactor technology that significantly improved microalgae productivity in comparison to the traditional culture systems. This technology makes microalgae production of interest for aquaculture beyond its consolidated role in hatcheries for most fish and shellfish larval stages. A study was carried out to evaluate growth response, feed utilization and quality traits of the edible portion of sea bass (Dicentrarchus labrax) fed diets including dried Tetraselmis suecica.
