Vitamin B supplementation in feeds has no benefits to the growth of Senegalese sole (Solea senegalensis) larvae, according to a study from the Abel Salazar Biomedical Sciences Instiute at the University of Porto in Portugal.

Regarded as an emerging aquaculture species, Senegalese sole commands a high market value, and has the potential to diversity the European aquaculture industry, the authors said. The need to produce a high quality and healthy larvae and juvenile fish is essential.
“Optimization of the nutrient content of larval feeds is critical as the diet plays an essential role in growth and skeletal development,” the authors stated.
The experiment involved a feeding trial to assess the effect of supplementing isonitrogenous and isolipidic feeds with three B-complex vitamins (180, 120 and 0.8 mg/kg of B1, B6 and B12, respectively), individually and in combination, on the growth performance and vertebral growth of Senegalese sole post-larvae.
“Results show that supplementing larval feeds with the tested vitamins and levels brings no additional benefits to growth and vertebral development,” the authors Michael Viegas, Maria Antónia Salgado, Carla Aguiar and Jorge Dias concluded in their study.
