Increasing wisdom of the deleterious results of poisonous parts in antifouling coatings has raised curiosity within the power for unhazardous choices. This booklet examines how marine organisms from micro organism to invertebrates and crops use chemical compounds to speak and guard themselves. chemical substances that hinder colonisation of dwelling surfaces are fairly pertinent to antifouling expertise and will motivate new strategies. The problem is to spot such compounds, establish the ability for sustainable construction and include them into coatings to provide long term antifouling efficacy.

Metabolites of E. , formoside, 7) collected from four different sites were effective antifeedants, and Defense of Benthic Invertebrates Against Surface Colonization by Larvae 19 inhibited attachment of a Vibrio harveyi strain to agar blocks at concentrations well below those occurring in the sponge. Antifouling activity was assessed in field assays, with compounds incorporated into Phytogel; compounds were initially incorporated into gels at two times whole-sponge concentrations, but as gels lose ~50% of their content over a 3-week deployment, this approximated natural levels in the sponge for the length of the trial.

In contrast, the antifeedant metabolites of Ectyoplasia ferox were most concentrated in the outermost 2 mm of the sponge. It is striking that the glycosides of E. formosus were antifouling, yet were more concentrated within the sponge, whereas those of E. ferox lacked antifouling activity but were present in the outermost layer of the sponge. This illustrates the importance of quantifying where metabolites are present within an invertebrate, as natural distributions may be counterintuitive to our naïve predictions.

Dictyol E and dictyol B acetate (34) were highly toxic to larvae prior to settlement, when dissolved in seawater at a dose lower than the effective concentration on the algal surface; in contrast, pachydictyol A and dictyodiol (35) were not toxic to larvae, but slowed growth and deformed development of juveniles (Schmitt et al. 1995, 1998). None of the Defense of Benthic Invertebrates Against Surface Colonization by Larvae 33 diterpenes was toxic to larvae of the bryozoan Amathia convoluta, but all inhibited metamorphosis and showed post-settlement toxicity at relevant concentrations; further, dictyol E and dictyol B acetate decreased settlement and juvenile development in the hydroid Eudendrium carneum (Schmitt et al.
