Para cada espécie utilizou-se quatro replicas de 0,35g. Cada amostra foi incubada nas salinidades five, 15 e 34e duas câmaras de temperatura (15 e 25°c) por quatro dias sob fotoperíodo de 14:10 h (14h de luz e 10 horas de escuro). Após o primeiro e o ultimo dia de incubação foram feitas medições com o PAM para determinar a fluorescência da clorofila a. Para verificar a influência dos factores ambientais testados (temperatura e salinidade) e a importância relativa de cada issue. Os resultados foram avaliados através de análise de variância para os efeitos principiais (ANOVA). Os resultados mostram que as duas espécies são capazes de adaptarem-se a variações nos parâmetros em
estudo embora de uma forma diferente.
