MARINE BIOLOGY ON THE PACIFIC COAST 

 the aquarium and museum, for seaside instruction 

 of university classes and for research. A power 

 boat, equipment for dredging and pelagic collecting, 

 and aquaria for observation or experiment are 

 maintained. 



A commercial aquarium at Avalon on Santa 

 Catalina Island, reached by steamer from Los An- 

 geles, often, by reason of its oceanic surroundings, 

 contains pelagic rarities and maintains an excep- 

 tionally fine exhibit of fish and crustaceans. 



The angling for the pelagic big game fishes off 

 Avalon is of interest both to the sportsman and 

 the biologist. The marvelously transparent water 

 in the harbor at Avalon makes possible the use 

 of glass-bottomed boats for the observation of the 

 rich and varied pelagic and bottom fauna and the 

 submarine forests of kelp. 



The Marine Biological Station (PI. XVII) of the 

 Scripps Institution for Biological Research of the 

 University of California, Professor W. E. Ritter, 

 Director, is located at La Jolla and is reached by 

 suburban train and motor service from San Diego. 

 La Jolla is a beautiful seaside village with good 

 hotel and cottages and the Station has a few cot- 

 tages on its premises for visiting biologists. The 

 station has a sea-going boat, the Alexander Agassiz, 

 equipped for oceanographic investigations, for 

 pelagic collecting, with tow nets, closing nets, etc., 

 and with dredging engine and cable for work to 

 the depth of 1000 fathoms. An excellent biological 

 library and research rooms are provided in the 

 building, and a wharf, pumping plant and viviers 

 are in process of construction. The Station is open 

 throughout the year and climatic conditions are 

 exceedingly favorable for biological investigations 

 at all seasons. 



Collecting Grounds. The productive salmon, 

 halibut and herring fisheries of Alaska and the 

 Northwest, and the pelagic fisheries of the albacore 

 (tuna) and other pelagic fishes off southern Cali- 

 fornia are commercial indices of the fertility of 

 the sea on the Pacific Coast. The biological stations 

 at Nanaimo and Friday Harbor are convenient cen- 

 ters for the collection of marine life in the sheltered 

 waters of the Northwest, which are famous for 

 the quantity of life they produce. The plankton 

 is especially rich in larval stages and often in 

 Noctiluca, and locally abounds in brackish water 

 forms such as rotifers and Evadne. The littoral 

 and tide-pool fauna is rich in hydroids, bryozoans, 

 echinoderms, molluscs, and annelids often of ex- 

 traordinary size, submarine fields of eel-grass and
