Gmelin) Steentoft M, L.M. Irvine & W.F.Farnham, was assessed in a traditional salina, a system of earthen ponds used formarine salt extraction taking advantages of solar evaporation and tidal cycle.Vegetative thalli of both species were cultivated in rafts holding polypropylene ropes,from January to June 2015, when lock-gates were opened during the period of no saltproduction. The effects of three factors in the net growth rate were analysed: seedlingdensity, water motion and seasonality. Water motion and seasonality showed asignificant effect in the growth of both species. Seedling density only showed asignificant effect in the growth of Gp. longissima, being the growth rates improved athigh seedling densities. Values of tissue N were generally lower than critical quotas,suggesting that maximum growth was limited by the concentrations of dissolvednutrients. In addition, the high salinity and temperatures in late spring seemed tocondition the values of net growth rate. The study suggested that macroalgal cultivationof these two valuable species could be a promising complementary activity in theintegrated management of the salina during winter and early spring, when salinity islower than 40 PSU, if nutrients in the water are increased with the semi-intensive fishcultivation and the hydrodynamic conditions along the rafts are enhanced PB Springer SN 1573-5176 YR 2019 FD 2019 LK http://hdl.handle.net/10498/34461 UL http://hdl.handle.net/10498/34461 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 11-nov-2026
