Crab sport fisheries in Humboldt Bay and Cresent City Harbor, California
Get PDFIn December 1964 interviewing of sport crab fishermen was
begun in Humboldt Bay. A similar study was initiated in
Crescent City in 1965. Fifty-four anglers interviewed at
Humboldt Bay in 1964 and 1965 caught 27 Dungeness crabs,
Cancer magister. The total estimated catch during the
sampling period was 400 Dungeness crabs.
Skiff fishermen in Crescent City caught an estimated 6,318
Dungeness crabs during the 1965-66 season; 1,666 Dungeness
crabs during the 1966-67 season and 5,054 Dungeness crabs
during the 1967-68 season. There is a good potential for
increased fishing in Crescent City Harbor, Trinidad Bay and
Shelter Cove. (10p.
Diablo Canyon power plant site ecological study Quarterly Report no. 17: July 1 - September 30, 1977
Get PDFDuring the quarter a total of 38 random 30-m2
and 152 random 1/4-m2 subtidal stations were
surveyed. Red abalone, Haliotis rufescens,
densities remained very low. There was a continued
decline in densities of giant red sea
urchins, Strongylocentrotus franciscanus, in
Diablo Cove as well as the North Control area.
The annual shore census of bull kelp, Nereocystis
luetkeana, revealed the lowest number of plants
in the surface canopy in Diablo Cove since 1973. The subtidal station data supported this observation.
Sea otter, Enhydra lutris, observations were
continued. A small group of otters continued
to raft in the Cove east of Lion Rock. Some
of these otters probably forage as far south as
South Cove.
The survey of 11 random intertidal stations
completed our Upwelling sampling effort. (16pp.
