“…Total protein contents of P. palmata were maximum in winter and minimum in summer, as previously shown by Galland-Irmouli et al (1999). The water-soluble carbohydrates values were in agreement with those recorded in previous studies, demonstrating that the amount of water-soluble sugars in G. turuturu ( Denis et al 2009;Munier et al 2013) is lower than that recorded for P. palmata (Morgan et al 1980;Morgan and Simpson 1981;Rosen et al 2000).…”

-Vibrio harveyi is the main pathogen of the European abalone Haliotis tuberculata, and recently caused important mortalities at the production sites of this marine gastropod in France. In the present work, the monthly antibacterial activity of two red seaweed species from the French Atlantic coast, the native Palmaria palmata and the introduced Grateloupia turuturu, were investigated against the abalone pathogen Vibrio harveyi strain ORM4. Water-soluble extracts were screened using the microplate method. Grateloupia turuturu showed an antibacterial activity with a maximal growth inhibition in spring of around 16%. In contrast, Palmaria palmata was inactive, as further growth of the bacteria was observed. Preliminary one-dimensional proton nuclear magnetic-resonance ( 1 H NMR) profiles identified the differences between the two water-soluble extracts.

“…Summer and winter maxima of dry matter content have also been reported for other algae (Wort 1955); however, these results partially disagreed with those of Vinogradov (1953), who found dry matter content of cold and temperate Rhodophyceae to be also high dunng summer and fall but low during winter. These differences in periods of maximal or minimal dry matter content seem due to geographical variations, as indicated by Morgan et al (1980) in Palmaria palniata and by Munda (1972) in several algae including Chondrus crispus. Neish et al (1977) showed that nutrient enrichment of seawater led to a decrease of dry matter content of C. crispus in culture.…”

Seasonal variations of distribution of the gametophytic and tetrasporophytlc generations, growth, carrageenans, phosphorus and nitrogen nutrition, and dry matter content were studied in 2 of the most contrasting forms of the red alga Chondrus crispus Stackhouse in Britanny. France. Seasonal variations of generations were more pronounced in the infralittoral than in the midlittoral form; the former had more reproductively mature plants and twice as many tetrasporophytes. Growth was greater in the infralittoral than in the midlittoral form. Contents of total carrageenans were comparable in the 2 forms; the K -, L -, and p-carrageenan structures did not vary significantly (qualitatively, quantitatively, during the year, or between the 2 forms). The midlittoral form had a higher total phosphorus content, more marked seasonal variations and an earlier spring decline than the infralittoral form Seasonal variations of total nitrogen content had different patterns in the 2 forins during summer The dry matter content of the infralittoral form was lower than that of the midlittoral form. These eco-physiological and biochemical differences and similarities are discussed in terms of the polymorphism of this alga.

“…Since P. palmata is one of the few seaweed in Europe used for food, its chemical composition has been investigated (Morgan et al 1980a). In recent years, interest in health foods, food supplements, new protein sources and novel bioactive compounds led to further research of the chemicals found in seaweeds (Løvstad-Holdt and Kraan 2011;Indergaard and Minsass 1991).…”

Most studies on multi-use concepts of aquaculture and wind farms explored cultivation feasibility of extractive species, such as seaweed or bivalves. However, recent studies also included the cultivation of crustaceans or fish culture in the vicinity of wind turbines. Consequently, new approaches combine fed and extractive species in integrated multi-trophic aquaculture (IMTA) concepts for offshore multi-use to reduce nutrient output and the overall environmental impact of aquaculture operations. In this chapter the findings of a series of mussel and oyster cultivation experiments over several seasons are presented, which were conducted at different offshore test sites in the German Bight. Sites were selected within future offshore wind farm areas for an explicit multi-use perspective. Results have demonstrated successful growth and fitness parameters of these candidates and
