Introduction Starting in 1986, the ANVAR contributed well appreciated financial support in order to set up an original seeding technique characterized by artificial seeding production in a laboratory. This advantageous new way of seeding, i.e. independency from nature, yield increase and true competitiveness compared to traditional methods, nevertheless requires strict adherence to a procedure progressively elaborated during numerous trials in laboratory as well as at sea. The program ended in July 1989 after testing the cultivation protocol on a 2 hectare exploitation scale, in order to better detect what could be improved to greatly increase productivity, facilitate the work of the harvester and to better adapt the operating mode to environmental...

Essai de cryoconservation des gamétophytes de l'algue alimentaire Undaria pinnatifida (Laminariale)
Provedor de dados: 5
Autores: Arbault, Suzanne; Renard, Philippe; Pérez, Rene; Kaas, Raymond.
Low temperature tolerance was determined for gametophytes of food alga Undaria pinnatifida according to various cryopreservation methods. Survival durations after storage in a medium containing 28% glycerol at −80 °C or in a 5-10% glycerol solution at −196 °C were only 9 and 4 days respectively. On the other hand, cooling at 5 °C/min. and storage at −15 °C for 15 minutes, without cryoprotective medium, did not reduce viability but this was highly decreased by storage for 15 minutes at −30 or −196 °C, with or without DMSO. The morphological cooling injuries were depigmentation and/or a contraction of the cells.

Efecto del alga invasora Undaria pinnatifida sobre la comunidad de peces de arrecife en los golfos Norpatagónicos
Provedor de dados: 20
Autores: Irigoyen, A.J.
This study investigates the impact of Undaria pinnatifida on the reef  fish assemblage associated with the coastal rocky reefs of Golfo Nuevo in northern Patagonia, Argentina. Undaria pinnatifida is a laminarian kelp, indigenous to the temperate regions of Japan, China and Korea. It has spread around the world by international shipping and has also been introduced in some regions for mariculture. Its expansion into the northern Patagonian gulfs and Peninsula Valdes, a UNESCO Natural Heritage Site, may threaten eco-tourism activities that depend on local biodiversity and the esthetic quality of the ecosystem. In particular, there is concern about the impact of Undaria on a variety of recreational activities including diving, angling and spear fishing, which...

Potential Use of Polysaccharides from the Brown Alga Undaria pinnatifida as Anticoagulants
Provedor de dados: 52
Autores: Faggio,Caterina; Morabito,Marina; Minicante,Simona Armeli; Piano,Giada Lo; Pagano,Maria; Genovese,Giuseppa.
Undaria pinnatifida (U. pinnatifida) is a highly invasive species and has caused concern all over the world because it has invaded coastal environments, has the potential to displace native species, significantly alters habitat for associated fauna, and disturbs navigation. Any attempt to eradicate it would be futile, owing to the elusive, microscopic gametophyte, and because the alga thrives in sites rich in anthropic activities. Venice Lagoon is the largest Mediterranean transitional environment and the spot of the highest introduction of non-indigenous species, including U. pinnatifida, which is removed as a waste. We demonstrated that polysaccharide extracts from U. pinnatifida have an anticoagulant effect on human blood in vitro and are not cytotoxic....
