| Summary: | <p><em>Spirulina</em> is blue green algae that have high nutrient content like protein and vitamin so itcan beused as source ofsingle cell protein (SCP). This research was conductedto know minimum doses of <em>Spirulina</em> in different protein feed on growth performance of tilapia. Experimental diets devided by two different protein level (25% of protein and 28% of protein) and three levels supplementation of <em>Spirulina</em> 0% (25A), protein level 25% supplemented<em>Spirulina</em> 3% (25B), protein level 25% supplemented<em>Spirulina</em> 6% (25C), protein level 28% supplemented<em>Spirulina</em> 0% (28A), protein level 28% suplemented <em>Spirulina</em> 3% (28B), and protein level 28% supplemented<em>Spirulina</em> 6% (28C). Testeds feedwere tilapia with average initial weight 17,24±0,29 g and density five fish/aquarium. Tilapia rearedin aquarium sized 50×40×35 cm<sup>3</sup> filledwith 30 cm waterand provided altrecirculation system. Fish were cultured for 40 days and fed <em>at satiation</em> with three times feeding frequency. All data analyzed statistically by one-way ANOVA.Result demonstrated that various dosesof <em>Spirulina</em> in different protein level of feed influencedspecific growth rate, feeding efficiency, protein deposition, and fat deposition. Fish were fed by feed containing <em>Spirulina</em> 3% in protein level 25% showed growth performance as same as fed of protein level 28%.</p> <p>Keywords: feed protein, <em>Spirulina</em>, growth performance, tilapia</p> |
