“…However, comparatively low consumption and high phlorotannin concentrations were found in basal reproductive blades (Pansch et al 2008). The lack of defense in vegetative blades is supported by findings of Steinberg (1985) and Winter & Estes (1992), showing low phenolic contents in vegetative tissue of the congener M. pyrifera. Irelan & Horn (1991) furthermore showed that polar extracts from M. integrifolia, incorporated in food pellets, had no influence on the feeding behavior of the herbivorous fish Cebidichthys violaceus.…”

“…Cystoseira) than those from FG1 (Tuya et al 2001). This avoidance is attributable to the rather coarse and tough body of the genera Cystoseira (physical factor), as well as to the presence of polyphenols (chemical factor; Winter & Estes 1992, Knoess & Glombitza 1993 as defenses against herbivores (Shunula & Ndibalema 1986). Despite the potentially confounding effects of chemical and morphological traits (Hay 1997), this hierarchy is in agreement with the susceptibility to being eaten as a function of algal morphology (algal functional groups) reported by Steneck & Dethier (1994), mainly for large invertebrates such as sea urchins in temperate seas.…”

We address the effect of several factors influencing the depth of interfaces between the shallow photophilic brown algal assemblages and Diadema antillarum urchin-dominated barrens on rocky reefs of the warm-temperate central-eastern Atlantic. By means of a multifactorial observational approach, we hypothesized that it would be locally influenced by (1) the functional structure of the dominant brown algal assemblages (corticated foliose algae versus large frondose coarselybranched fucoid species), in addition to (2) the fishing status (fished versus unfished sites) and (3) the large-scale topography of the substrate. Our results show that brown algal assemblages reach deeper waters at unfished sites, which is independent of the dominant brown algal functional group. However, monospecific algal facies dominated by large frondose coarsely branched fucoid species (mainly the genera Cystoseira) reach deeper waters in comparison with corticated foliose algae, at fished sites.

“…E. bicyclis contains high levels of several phlorotannins, which exhibit diverse biological activities, including anti-oxidative properties (Yoon et al, 2011). Usually, polyphenolic compounds from brown algae have been considered to deter grazing by and growth of abalone (Winter and Estes, 1992). Abalone prefer to eat phenolic-poor rather than phenolic-rich seaweeds.…”

“…However, E. bicyclis has a bitter tannin-rich taste; it is also tough in texture and is thus unappetizing. Abalone grazing is known to be inhibited by polyphenolic compounds from brown seaweed (Winter and Estes, 1992). Thus, we changed the abalone feed to E. bicyclis after 4 d of starvation.…”

Abalone containing phlorotannins is produced by feeding the phlorotannin-rich brown seaweed Eisenia bicyclis after 4 days of starvation. Reverse-phase high-performance liquid chromatography (RP-HPLC) was used to isolate and quantify phlorotannins, which were identified by mass spectrometry and [ 1 H]-nuclear magnetic resonance to be the P1 compound, 7-phloroeckol, and eckol. When E. bicyclis was used as feed, P1 compound accumulated to an average of 1.60 mg/g dry weight of abalone muscle tissue after 18 d, 7-phloroeckolol to 0.21 mg/g after 16 d, and eckol to 0.22 mg/g after 12 d. Saccharina japonica was used as a control feed, and the abalone showed little or no accumulation of phlorotannins in muscle tissue. Feed consumption and growth rate were very similar when either E. bicyclis or S. japonica was fed for 20 d. Half-maximal reductions in the levels of P1 compound, 7-phloroeckol, and eckol accumulation were attained in 1.5, 1.9, and 3.4 days, respectively, after the feed was switched from E. bicyclis to S. japonica. Value-added abalone containing bioactive phlorotannins can be produced by simply changing the feed to the phlorotannin-rich E. bicyclis 18 d prior to harvesting.
