OCEAN HABITAT DEVELOPMENT This project, which began in April, 1958, is designed to explore the possibilities of improving sport fishing in coastal waters. The two principal means to be used are: 1. Development of artificial reefs. 2. Transplantation of kelp and development of new kelp beds. In the short time before the end of the biennium rvvo artificial reefs were placed along the coast. The first was a car body reef in an area devoid of fish and cover off Paradise (near Malibu) in 50 feet of water. At last check, about 150 fishes of six species had been attracted to the "; A second area, similarly bar- ren of fishlife and cover, was selected off Huntington Beach. Some large artificial rocks, made of gunite for a Hollvwood movie, were placed in 55 feet of water. The "rocks" weigh up to t\\o tons apiece. Lines \\-ere tied into place for the later attachment of kelp. This "reef" had not been checked since its placement. Observations and evaluation of results, as well as kelp transplantation, will be made by the project's biologist divers, using SCUBA (self-contained under- water breathing apparatus). As part of the program, a study is also being made for comparative purposes of natural rocks and reefs and other habitat, as well as of .shipwrecks which are the homes of great numbers of fishes. Marine life on and around offshore oil islands and platforms is also being studied to evaluate the changes occurring around manmade habitat. Other phases of the Habitat Development Study will include a study of the possibilities
