Abstract
Search for novel best-performing starter feed ingredients is one of the main challenges of modern aquaculture industry. The goal of this article is to evaluate the effect of microalgae supplementation enriched with omega-3 polyunsaturated eicosapentaenoic acid and the powerful antioxidant fucoxanthin on growth performance of Red tilapia fry (Oreochromis mossambicus × Oreochromis niloticus). We formulated three experimental diets, using two strains of microalgae from our culture collection – Vischeria magna SBV-108 (Eustigmatophyceae), rich in eicosapentaenoic acid and Mallomonas furtiva SBV-13 (Chrysophyceae), rich in fucoxanthin – and their combination. Vischeria magna SBV-108 is a new strain which biochemical properties and growth characteristics have not been previously studied. Coppens Supreme-15 was used as a control diet. The best growth performance was recorded in eicosapentainoic acid enriched Diet 1 (10% w/w V. magna), that significantly (P<0.05) overperformed control feed on absolute growth, average growth, specific growth rate, feed conversion rate, protein efficiency ratio, protein productive value and energy productive value. Diet 3 (5% w/w V. magna and 5% w/w M. furtiva) and Diet 2 (10% w/w M. furtiva) were not significantly different from control at most parameters. Generally, supplementation of feed with microalgae rich in omega-3 eicosapentaenoic acid significantly improved Red tilapia fry growth parameters and overall feed performance, while supplementation of feed with microalgae rich in antioxidant fucoxanthin was not beneficial compared to the control.
期刊介绍：
The Journal of Applied Phycology publishes work on the rapidly expanding subject of the commercial use of algae.
The journal accepts submissions on fundamental research, development of techniques and practical applications in such areas as algal and cyanobacterial biotechnology and genetic engineering, tissues culture, culture collections, commercially useful micro-algae and their products, mariculture, algalization and soil fertility, pollution and fouling, monitoring, toxicity tests, toxic compounds, antibiotics and other biologically active compounds.
Each issue of the Journal of Applied Phycology also includes a short section for brief notes and general information on new products, patents and company news.
