DESCRIZIONE
The invention relates to the use of an antifouling composition and to an aquaculture pen for sheltering and feeding aquatic life, comprising: a) a supporting structure: and b) a netting attached to the supporting structure; said netting containing a continuously submerged portion, wherein said submerged portion of the netting defines a containment volume for containing the aquatic life; and wherein at least said submerged portion of the netting comprises an antifouling composition containing a cross-linked silicon polymer obtainable by cross-linking a silicon composition containing: i) a first silicon polymer having formula CH2=CH-(Si(CH3)2-0)n-CH=CH2 wherein n is an integer from 2 to 200; ii) a cross-linker containing a second silicon polymer having formula Si(CH3)3-0-(SiCH3H-0)m-Si(CH3)3 wherein m is an integer from 2 to 200; and iii) a metal catalyst wherein the metal is chosen from the group consisting of platinum, palladium and rhodium.
