Abstract
Two designs of artificial shelters were evaluated for use in the artis anal spiny-lobster fishery in Gazi Bay, Kenya. Both types of shelter w ere effective in aggregating the spiny lobster Panulirus ornatus in ne arshore seagrass beds. Lobsters aggregated at the shelters were caught by free-diving fishermen, using spearguns and hand nets. Mean lobster catches taken from the shelters ranged from 0,38 to 0,83 kg . trip(-1 ), around 50% of those taken farther offshore in natural reefs. No sig nificant difference was found in the size or sex composition between s helter and reef-caught lobsters.
