Biology of the mullet species occurring in the estuaries of Freetown Peninsula

This brief paper gives some notes on the geographical distribution and salinity tolerances of some Mugil species occurring in the Black-Johnson estuary, Sierra Leone

Some data on landings of pelagic fish by the artisanal fishermen near Freetown during January-December 1978

Pelagic fish (except for tuna) are landed in Sierra Leone mainly by the artisanal fishermen. The two most important species are Sardinella and Ethmalosa.Deep-sea species are normally exploited by purse seiners of foreign countries. The landings of artisanal fishermen largely comprise Sardinella eba.Landing data for Sardinella landed at Tombo and Goderich, and for Ethmalosa at Tombo, are presented in tabular form. Collection methods are described, with a definition of the unit of fishing effort, and a description of the gear used.The landing data are discussed with particular attention to fishing effort, catch per unit effort, and price per ton

Report on the physical, bacteriological and biochemical analyses of seawater samples collected off existing sewage outfalls in the Sierra Leone River Estuary

The studies reported were undertaken as part of a wide environmental feasibility study for the establishment of a modern sewage system in Freetown. The aim of this part of the study was to determine whether the hydrological regime of the Sierra Leone River Estuary would permit the large-scale introduction of sewage into the estuary without damaging the environment. The important factors were whether: 1) there would be sufficient dilution of the sewage; 2) fleatable particles or other substances would create significant adverse effects in the estuarine ecosystem. The outfall sites are described together with the sampling stations, methods and analyses. Results include: 1) T/S profiles; 2) chemical analysis of the water. A review of literature on the Sierra Leone River Estuary is included which provides information on the plankton, benthos and fisheries. Results suggest that at certain points where local circulations occur it would be inadvisable to locate untreated sewage outfalls. Such points are frequently observed in small embayments. These studies have been of short duration but the data can serve as baseline for more extended investigations which would give a more complete picture of the seasonal patterns in the estuary.

(Report of the) Institute of Marine Biology and Oceanography, Fourah Bay College, University of Sierra Leone

Details are given of the Institute and its activities, in particular the research projects being undertaken. These include studies on the marine molluscs of Sierra Leone, the cockle fishery, a preliminary investigation on the fouling organisms affecting the raft-cultured oyster populations, larval oyster ecology in relation to oyster culture, preliminary studies on the reproductive cycle of the mangrove oyster (Crassostrea tulipa), and catch composition of fishes taken by beach-seines at Lumley (Freetown). Records of the west African manatee (Trichechus senegalensis) are noted.

Marine biology of the Sierra Leone River Estuary. 1. The physical environment

The Sierra Leone River Estuary is a relatively young drowned river valley, it is shallow except for a deep channel which passes close to the Freetown shoreline. The upper reaches merge into a network of creeks and channels fringed by large areas of mangrove swamps. It is a tidal estuary of the semi-mixed type with the saline oceanic water entering it on a diurnal cycle. The climate of Sierra Leone is marked by a very distinct change between a very wet rainy season and a dry season. The tidal range of the Estuary (spring 3.03m; neap 2.28m) does not impede normal use of the harbour. The tidal variations can be felt as far as 42 miles inland along the water courses of the Sierra Leone River and its tributaries. The volume of fresh water entering the Estuary is large during the rainy season and greatly reduced during the dry season. Consequently there is a marked fall in salinity during the rainy season and higher salinities due to the marine influence prevailing during the dry season. The nature of the shores and bottom, the hydrography and chemistry of the estuarine system have been outlined in relation to the prevailing climatic conditions.

El desempeño de Unamsil en el programa DDR durante el proceso de paz en Sierra Leona. Estudio de caso: los niños soldados. 1998-2005

El interés de este Estudio de Caso es investigar la manera en que la Misión de Paz de la ONU en Sierra Leona (UNAMSIL) redireccionó el programa Desarme, Desmovilización y Reintegración (DDR) hacia los niños soldados durante el post-conflicto en el país. Se analiza cómo a través de la coordinación de diferentes Agencias y Organizaciones Internacionales con UNAMSIL, el Gobierno y la Sociedad Civil hace posible que se refuerce el rol de los Interim Care Centers (ICCs) en donde se enfrentaron las necesidades esenciales de los menores excombatientes para lograr un mejor proceso de su desmovilización y reintegración. Se explica de igual forma, las diferentes herramientas que sirven para llevar a cabo la resolución del conflicto y la reconstrucción de la paz, enfocándose en el peacekeeping, peacemaking y peacebuilding, como mecanismos que ayudaron a crear un espacio seguro para los niños exsoldados. Por último, se exponen los alcances y límites de los ICCs con respecto a la reintegración de los menores excombatientes

Incidencia de los actores internacionales no estatales en los conflictos internos. Estudio de caso: la participación de las empresas militares privadas “Executive Outcomes” y “Sandline International” en la guerra civil de Sierra Leona (1991-2002)

La Participación de las Empresas Militares Executive Outcomes y Sandline International en el conflicto de Sierra Leona fue una de las primeras veces en las que se vieron en escena a estos actores confluyendo en un nuevo orden internacional; y este estudio de caso busca determinar la manera de actuar de estas empresas y su incidencia en el conflicto. El caso de Sierra Leona es uno de los principales acercamientos a este nuevo fenómeno, que empezó a ejercer funciones que tradicionalmente le correspondían a los Estados y que han llevado a una privatización de la seguridad. Por medio de este estudio de caso se busca también determinar cuáles son las falencias y los retos que acarrean a las Empresas Militares Privadas en cuanto a su intervención en los conflictos internos. El caso de Sierra Leona es fundamental en tanto fue uno de los conflictos más intensos desarrollados en África en la década de los 90; y fue el momento en el cual las Empresas Militares Privadas empezaron a estar en la mira internacional a causa de estas intervenciones que generaron tanto críticas negativas como positivas.

Delays in childhood immunization in a conflict area: a study from Sierra Leone during civil war

ABSTRACT: BACKGROUND: Sierra Leone has undergone a decade of civil war from 1991 to 2001. From this period few data on immunization coverage are available, and conflict-related delays in immunization according to the Expanded Programme on Immunization (EPI) schedule have not been investigated. We aimed to study delays in childhood immunization in the context of civil war in a Sierra Leonean community. METHODS: We conducted an immunization survey in Kissy Mess-Mess in the Greater Freetown area in 1998/99 using a two-stage sampling method. Based on immunization cards and verbal history we collected data on immunization for tuberculosis, diphtheria, tetanus, pertussis, polio, and measles by age group (0-8/9-11/12-23/24-35 months). We studied differences between age groups and explored temporal associations with war-related hostilities taking place in the community. RESULTS: We included 286 children who received 1690 vaccine doses; card retention was 87%. In 243 children (85%, 95% confidence interval (CI): 80-89%) immunization was up-to-date. In 161 of these children (56%, 95%CI: 50-62%) full age-appropriate immunization was achieved; in 82 (29%, 95%CI: 24-34%) immunization was not appropriate for age. In the remaining 43 children immunization was partial in 37 (13%, 95%CI: 9-17) and absent in 6 (2%, 95%CI: 1-5). Immunization status varied across age groups. In children aged 9-11 months the proportion with age-inappropriate (delayed) immunization was higher than in other age groups suggesting an association with war-related hostilities in the community. CONCLUSION: Only about half of children under three years received full age-appropriate immunization. In children born during a period of increased hostilities, immunization was mostly inappropriate for age, but recommended immunizations were not completely abandoned. Missing or delayed immunization represents an additional threat to the health of children living in conflict areas.
