from ballyhoo, flying fish and small jacks to
shrimp, squid, filefish and seahorses,” he reports.
Mahi, in turn, become forage for even larger
game species, such as blue marlin, big tuna and
sharks. “That’s another reason dolphinfish hang
around sargassum,” says Hammond. The weeds
give even mature mahi a place to hide.
Interestingly, holopelagic sargassum
depends on fish as much as fish depend on it,
says Oxenford. “Sargassum relies on the feces of
its inhabitants for nutrients,” she says. The more
fish, the greater amount of nutrients generated
and the faster the sargassum grows.
PADDY PURSUIT
Schools of warm-water game fish such as mahi,
striped marlin, yellowfin tuna and California
yellowtail often migrate northward along the
Pacific coast of Baja and Southern California in
summer. In El Niño years, anglers might also get
a shot at wahoo or blue marlin.
This is when anglers seek out offshore kelp
paddies in earnest. Sometimes, you can observe
the offshore food chain by peering below a kelp
paddy. Small baitfish, such as anchovies and
small sardines, hover just below, while larger
Pacific chub mackerel and jack mackerel school
slightly deeper. If you’re fortunate, you’ll catch a
glimpse of larger game fish.
Yet, as with patches of sargassum, not all
offshore kelp paddies hold game fish. Like that
McDonald’s I mentioned earlier, but with no
customers, some are devoid of large predators
at any given time. While little or no scientific
research exists on what makes one floating kelp RICHARD HERRMANN (ABOVE), JIM HENDRICKS (OPPOSITE)
