Summary
<p>In this study it was aimed to produce a commercial aquatic plant Vallisneria spiralis in a controlled- aquaculture system. In order to determine the potential of the plant to utilize different nutrient resources relative growth rate depends on biomass yield and individual plant number and length composition of V. spiralis cultivated in semi-shadow and nonshadow conditions were determined. Results of the present work showed that V. spiralis utilized different nutrient resources effectively such as cow, lamb, chicken and commercial fertilizer TSP in cultivation conditions and increased its weight and individual number compare to the control group where nutrient addition is not applied. In semi-shadow condition V. spiralis fresh biomass yield and plant number increase were the highest in cow group and found to be 1.52%±0.03 g.day-1 and 1.80%±0.05 individual.day-1 respectively. The mean length of V. spiralis was found to be the highest (83.56±26.14 cm) in lamb fertilizer group. In non-shadow conditions V. spiralis fresh biomass yield and plant number increase were the highest in cow group and found to be 2.73%±0.07 g.day-1 and 2.52%±0.6 individual.day-1 respectively. The mean length of V. spiralis was found to be the highest (92.74±27.93 cm) in cow fertilizer group as well. </p>
