Fish landing data collected by the Kenyan Fisheries Department from the nearshort coastal marine waters from 1985 to 1994 were statistically analyzed to determine trends in the traditional fisher's catch. Over the ten year period a significant decline occurred for total catch and for catches of seven commercially important fish families: Lethrinidae, Siganidae. Lutjanidae, Scaridae, Carangidae, Scombridae and Mullidae. 1994 registercd the lowest catch over ten years. The total catch for all the fish declined from a mean annual catch of 6150 metric tonnes in the 1980's to a mean of 5141 metric tonnes in the 1990's with the catch for 1986 being 2 times higher than that of 1994. Although Mombasa district had the highest mean annual landing, its total landings like that of Lamu and Kwale districts decreased over the years. However, Kilifi district showed a steady increase in catches over the years. The changes in fish landings is thought to be caused by lack of appropriate fishing regulations, leading to overfishing of the lagoonal reefs beyond their maximum sustainable yields.

O objetivo e discriminar os clones quanto a produtividade e ao numero de colheitas baseado nos resultados referentes aos ensaios avancados, ou seja, aqueles que antecedem a recomendacao dos materiais, no periodo de 1985 a 1994. Para isso, foram realizadas analises de variancia individuais, para cada experimento, e uma analise de variancia conjuntas, para cada experimento, e uma analise combinada, envolvendo todos os clones, experimentos e anos.

The Shiplap House, 18AP30, located at 18 Pinkney Street, Annapolis, Maryland, was built ca. 1716. Located within the Historic District of Annapolis, Maryland (see Figures 2, 3, & 4 for site location within the Annapolis Historic District), the Shiplap House lies in immediate proximity to features of local and national importance. Due to its potential as a significant archaeological site, the Shiplap property was selected as one of the locations to be investigated during the 1985 summer Fieldschool in Urban Archaeology, a course offerred by the University of Maryland, College Park, under the direction of Dr. Mark P. Leone.
