The Namibian Kelp
(Laminaria pallida) commonly referred to as the split-fan kelp
, belongs to an aquatic group of algae, commonly referred to as seaweeds.
Sea urchins fed long-term frozen kelp
displayed significantly smaller final test diameters than those fed kelp
stored by any other method tested, and smaller final wet weights than those fed short-term frozen or dry kelps
Potential "added mass" or "acceleration reaction" forces were neglected for the intertidal kelps
on the basis of data from Gaylord (2000), and were ignored for the subtidal kelps
because fluid accelerations are small in habitats outside the surf zone (Denny, 1988).
The filaments of both bull and winged kelps
grow noticeably slower in acidic seawater, she reported last week at the 2008 Ocean Sciences Meeting in Orlando, Fla.
Although the importance of kelp
bed variability (including kelp
density, distribution, and species composition) to fishes has been demonstrated in Alaskan waters (Dean et al., 2000; Hegwer, 2003; Hamilton, 2004; Calvert, 2005), the role of seasonality in these habitats is poorly understood, particularly in regions with seasonal extremes, such as the subarctic (but see Calvert, 2005).
It forbids harvest from state-owned submerged lands without a lease unless the harvester is removing less than 2,000 pounds of kelp
each year for "human consumption," an undefined term.
The giant kelps
were tagged with plastic-coated wire that was looped around haptera, and the tags were replaced as they were overgrown; stipitate plants were tagged with Floy spaghetti tags tied on the stipes.
had been thought to have limited potential for extended dispersal, largely because fertilization occurs only after spores have dispersed and finally settled on the bottom (see Dayton 1985, Schiel and Foster 1986, and Santelices 1990 for reviews).
Just how much of the difference in reproductive timing between the two kelps
is adaptive vs.
Patterns of algal turf abundance between locations with and without sea otters [ILLUSTRATION FOR FIGURE 8 OMITTED] were similar to but less extreme than those for understory kelps
. Mean turf cover differed significantly between Sitka Sound vs.
And I've been getting a lot of interest in kelp
farming from lobstermen because aquaculture kelp
is a winter crop.
