    ABSTRACT: The viability of industrial culture of Undaria pinnatifida (Harvey) Suringar and Laminaria saccharina (L.) Lamouroux using Western techniques requires an indoor phase to obtain collector strings on which many sporophytes are attached, which can then develop during the mariculture phase. The present paper studies the impact on final sporophtye richness of the characteristics of the string, and its number of previous treatments. Plaited string was clearly superior for both species, and a single previous treatment was enough to guarantee a suitable density of sporophytes for seeding.

    ABSTRACT: Macroalgal invasions in coastal areas have been a growing concern during the past decade. The present study aimed to assess the role of hull fouling on recreational yachts as a vector for macroalgal introductions. Questionnaire and hull surveys were carried out in marinas in France and Spain. The questionnaires revealed that the majority of yacht owners are aware of seaweed introductions, usually undertake short range journeys, dry dock their boat at least once a year, and use antifouling paints. The hull survey showed that many in-service yachts were completely free of macroalgae. When present, fouling assemblages consisted mainly of one to two macroalgal species. The most commonly found species was the tolerant green seaweed Ulva flexuosa. Most of the other species found are also cosmopolitan and opportunistic. A few nonnative and potentially invasive Ceramiales (Rhodophyta) were found occasionally on in-service yachts. On the basis of the information gathered during interviews of yacht owners in the surveyed area, these occurrences are likely to be uncommon. However they can pose a significant risk of primary or secondary introductions of alien macroalgal species, especially in the light of the increase in yachting activities. With large numbers of recreational yachts and relatively rare occurrences of nonnative species on hulls, comprehensive screening programs do not seem justified or practical. The risks of transferring nonnative species may, however, be minimized by encouraging the behaviors that prevent fouling on hulls and by taking action against neglected boats before they can act as vectors.

    ABSTRACT: The Asian kelp Undaria pinnatifida was first reported in north-western Spain in 1988. Since then, it has spread along the Galician coasts and towards the western Cantrabrian coast, probably supported by new introductions related to aquaculture and private yachts. Despite the high potential of this seaweed to invade new areas, it has not fully established itself in specific areas along the eastern Cantabrian coast where it has been farmed. We attempted to identify the macro-environmental determinants for the successful establishment of U. pinnatifida in the northern Iberian coast. Thus, we built a model based on the significant relationships between this kelp and several environmental factors using the Favourability Function, a method based on binary logistic regression. We obtained a statistically significant Favourability model where the chlorophyll concentration in summer was the most influential variable and the photosynthetically active radiation in spring was a secondary variable that best characterized the presence of U. pinnatifida. The ecological implications are discussed.
