Description:
During the year of 1999, the red seaweed Gracilaria verrucosa (Hudson) Papenfuss (Rhodophyta, Gracilariales, Gracilariaceae), has been followed monthly in Bizerte lake (in the north of Tunisia). The parameters studied are: biomass, agar-yield, gel strength, gelling and melting temperatures. The results showed that the highest average of wet biomass is recorded in June (2500 g/m super(2)) and the lowest is obtained in October (130 g/m super(2)). The highest agar-yield is obtained in April (37,92 %) ; while the lowest is recorded in September (10,67 %). High and low gel strengths are obtained in May (410g /cm super(2)) and in December (125 g :cm super(2)), respectively. Gelling temperature varies between 31 degree C and 44~ 'C, while melting temperature varies between 79 degree C and 100 degree C
