A survey of fisherfolk involved in artisanal fisheries in some selected areas of Ikorodu in Lagos State

The study focused on men and women involved in artisanal fisheries in some selected areas of Ikorodu Local government in Lagos State. The random sampling technique was used to select 50 fishermen each at Ibeshe and Baiyeku sites. The results revealed that majority of the fishermen were male, christian, semi-illiterate, and married. Data were collected on capital sources, labour used, income, gear techniques and type of fish caught. Analysis showed that the highest sources of capital were from personal savings (50%). Majority of labour used were hired labour, 44% at Ibeshe and 50% at Baiyeku. Highest monthly income ranged between N10, 000 - N25, 000 at both sites. Planks were mostly used at both sites for fishing boats as well as means of transport (Ibeshe 68%, Baiyeku 72%). Common fishing gear was the gill net, The fishes caught were found to be of various tyupes. Ethalmalosa fimbriata constituted the highest fish species caught by weight and number at both sites (50%). However, the problems of capital source were most peculiar coupled with high cost of fishing materials and labour scarcit

Survival and response of Oreochromis niloticus to different feeds

The study determined the survival and the response of Oreochromis niloticus to different feeding compositions. 90 Oreochromis niloticus juveniles were fed different diets in triplicated treatments inside glass tanks. Treatment I comprised locally compounded diet; Treatment II, imported pelletized feed; and Treatment III - processed feathermeal based diet. Results showed that there was no significant differences (P>0.05) in the weight gain, feed intake, survival and feed conversion ratio. However, Treatment I had the highest feed intake, while treatment n had the highest weight gain and feed conversion ratio

Characterization and Taxonomic Classification of Soils in Onigambari Forest Reserve South Western Nigeria

A soil survey of Onigambari forest reserve in Oyo State, Nigeria was carried out. Three soil mapping units Established-Teak-Plantation (ETP), Natural-Forest (NF) and Farm-Land (FL) were identified with observation base on vegetative pattern. Morphological properties of the study area show that the soil unit ETP is deep and texture ranges from loamy-sand at the surface to sandy clay loam in the subsurface. The soil unit NFand FL is not deep due to presence of hard pan but the texture ranges from sandy-loam to sandy-clay and loamysand to sandy-clay respectively. Physical properties of the soils showed the bulk density of the soils to be moderately good for growing plant with high porosity. The soils chemical properties indicate that the pH value of the soils in ETP, NF and FL are slightly acidic and organic-matter was very low in the soils of ETP compared to NF and FL soils. The total-nitrogen values of the soils in the area changed irregularly with depth and values ranged from 0.028 to 0.1g kg1 in ETP, 0.05 to 0.25g kg-1 in NF, the value ranged from 0.03 to 0.26 g kg-1 in FL. 0.03 to 0.26 g kg-1. According to USDA soil Taxonomy system, all the profiles pits in the study area showed distinguishing characteristics of the order Alfisols, therefore the soils are classified as Alfisols. Profile in the Established-Teak-Plantation is classified as Typic isohyperthermic paleustalfs, Profiles Natural-Forest and Farm-Land with petro-plinthic material within 100cm of the soil surface qualified as plinthic isohyperthermic paleustalfs

Assessment of Markers of Depression and CD4 Cell Count among Adult HIV-Positive Patients on Anti-Retroviral at a Nigerian University Teaching Hospital

Objective: Depression is a common mental health problem among people living with HIV/AIDS (PLWHA); because low count of lymphocytes with  cluster of differentiation 4 (CD4 cell count) is associated with severe symptoms of HIV infection, there are thoughts that low CD4 cells count can provoke depressive illness. This study was conducted to determine the relationship between CD4 count and depression among adult HIV positivepatients attending Family Medicine clinics at University of Ilorin Teaching Hospital (UITH), Ilorin, Nigeria.Method: A hospital based descriptive cross-sectional study was done over a period of 6 months among 350 systematically randomly selected adult HIV-positive patients. PHQ-9 was used to obtain information on depression and the CD4 count was determined using a flow-cytometric method. Data were obtained and analyzed using SPSS-17. Chi-square was used to determine degree of association between the depression and the level of CD4 count. P-value of < 0.05 was considered statistically significant.Results: The prevalence of depression among the respondents was 33.4%. The prevalence of depression was highest among respondents with low CD4 count (≤349cells/ul), 37.0%, and least among those with high CD4 count (≥500cells/ul), 28.3%. This relationship was however not statistically significant.Conclusion: The overall prevalence of depression was high among the respondents (33.4%) suggesting the need for routine depression screening among HIV positive patients. There was no statistically significant association between presence of depression and level of CD4 count (p-value=0.302). Keywords: Depression, CD4count, PLWHA, Family Medicine, UITH
