SIZE:
10 cm to 30 cm, can reach up to 70 cm.
LIFE EXPECTANCY:
Less than one year.
LIFE CYCLE:
The reproductive process is still unclear to scientists. The assumption is that slimy whip weed reproduces like other brown algae. However, no evidence has yet been found to validate this theory.
Brown algae reproduce sexually. Spores are released, giving birth to organisms called gametophytes. These produce male and female reproductive cells. When they meet, a new alga is formed.
Slimy whip weed is a thread-like algae. Its frond consists of a main axis, to which are attached long, whip-like branches no more than 3 mm wide. These threads can carry many shorter ones. Its color varies from dark brown to black.
Coastal zone, up to 3 m deep.
Slimy whip weed clings to rocky bottoms and likes areas exposed to waves.
PREYS:
CO2
Solar energy
PREDATORS:
Herbivorous molluscs
This algae is not yet commercially harvested in Quebec.
Slimy whip weed is a Smarter seafood listed species.
BENEFITS:
Brown algae from the Chordariaceae family contain a number of health-promoting elements, such as dietary fiber and antioxidants.
Moreover, certain isolated compounds are thought to have potential anti-coagulant, anti-viral, and immunological properties.
LET’S COOK:
Slimy whip weed is in the same family as mozuku (Chordariaceae), an algae from the Okinawa region of Japan. It could therefore be eaten in a similar way. Traditionally, the Japanese serve this type of algae raw in a vinegar sauce. They also use it in soups. Slimy whip weed is said to have a “slightly slimy, yet appetizing” texture.
The waters of the St. Lawrence are known for their good quality. However, as algae absorb the elements present in the water in order to grow, it is preferable to make sure that the harvesting site is clean before eating them fresh.
