Cultivation of the seaweed Ulva spp. with effluent from a shrimp biofloc rearing system: different species and stocking density
<p>This work evaluated the use of effluent from a marine shrimp biofloc rearing system to cultivate the green seaweed <em>Ulva</em>. First, the growth of two <em>Ulva </em>species, <em>U. ohnoi</em> and <em>U. fasciata,</em> was evaluated. Second, the best-performing species was cultivated under two different stocking densities (2 g L<sup>-1</sup> and 4 g L<sup>-1</sup>) to evaluate both growth and nutrient uptake rates, considering total ammonia nitrogen, nitrate, and orthophosphate. In both cases, environmental variables were monitored, and the cultivation medium, consisting of 25% biofloc water and 75% seawater, was exchanged weekly. <em>U. ohnoi</em> grew significantly better, considering all variables evaluated (<em>p</em><0.05). The smaller stocking density produced a higher specific growth rate (<em>p</em><0.05). Yield, however, was unaffected (<em>p</em>≥0.05). No significant differences in the nutrient uptake rates were observed (<em>p</em>≥0.05). Overall, this work highlights the importance of species selection for seaweed destined for aquaculture. Additionally, it also optimizes the cultivation of seaweeds, specifically <em>U. ohnoi</em>, using effluent from biofloc systems.</p>

Test of different substrates to Ulva spp spore recruitment
<table> <tbody> <tr> <td> <p><strong>We tested different plastic materials and depths for fixing the spores of the filamentous macroalgae Ulva spp that occurs in the farm's ponds. The objective was to select the best material for the structures and the best cultivation depth. Six different treatments were tested: PVC panel close to the surface, PVC panel 1.2 cm from the surface, PVC panel 3 cm from the surface, PVC panel coated with plastic bag 1.2 cm from the surface, half a PVC pipe, and half a PET bottle. Each treatment had 4 repetitions. The structures were maintained in the supply channel for 30 days. During the test the temperature, salinity, pH, dissolved oxygen (DO), and transparency were monitored, and taken weekly photographic of macroalgae. The harvested macroalgae were weighed to obtain the total mass produced and to calculate the total productivity.</strong></p> </td> </tr> </tbody> </table>
