Organic waste reclamation, recycling and re-use in integrated fish farming in the Niger Delta

The purpose of this paper is to create awareness on the significance of integrated fish farming in organic waste reclamation, recycling and re-use. Example of integrated fish farming practiced at a micro-level in the Niger Delta of Nigeria is crop-snailry-poultry (Chicken) – livestock (pig) – cum-fish production. In this system, fish production remains the most important activity. The organic wastes reclaimed, recycled and re-used in this system are: plant matter, chicken and pig excrements; snail, oyster and periwinkle shells, ox blood and bone, fish wastes, palm kernel cake, groundnut cake, pond silt and aquatic fern, Azolla pinnata. Other reclaimable, recyclable and re-usable materials are also discussed in this paper. Integrating organic waste reclamation, recycling and re-use in integrated fish farming with treatment, incineration, landfill and composting will help to drastically reduce waste in both rural and urban areas.

Complication amoebic liver abscess still a significant health problem in the tropics: 3 clinical case reports

Amoebic liver abscess still poses a serious clinical problem in tropical countries. Here we describe three complicated cases to illustrate the magnitude this disease condition could assume in the tropics. Limited access to health facilities as well as poverty and ignorance result in patients presenting late, often with complications, which compounds the problem of differential diagnoses. The need for improved sanitary conditions, and qualitative health care delivery in the tropics to positively alter the epidemiology of this disease becomes more imperative.

Microbiological quality of raw and processed farm reared periwinkles from brackish water earthen pond Buguma, Nigeria

The microbiological quality of raw and processed periwinkles obtained from brackish water earthen pond of the African Regional Aquaculture Centre, Buguma, Rivers State, Nigeria was studied. The samples were harvested at exactly 11 am on a Monday morning, at high tide and water temperature of about 29°C. Ninety samples were analyzed and used for the study, which comprised the enumeration of indicator organisms and other pathogens as well as their total counts. Total bacterial counts ofthe samples from boiled periwinkle meat, boiled shell-on periwinkles and raw periwinkle meat wer

Hematological responses of Tilapia guineensis to acute stress

The effects of acute stress due to handling and transportation on the hematology of Tilapia guineensis was investigated. A total of sixty T. guineensis consisting of thirty juvenile fish (mean length 15.68m±322SD; mean weight 90.36g ±4.81SD) and thirty adult fish (mean length 22.74cm ± 4.78; mean weight 412.92g ± 6.23) were harvested from the recruitment ponds of the African Regional Aquaculture Centre, Brackish water Research Fish Farm, Buguma, Rivers State, Nigeria. Their blood samples were immediately taken at the site. They were then subjected to series of handling procedures like capture, sorting and transfer from the pond site to hatchery. The fish were later transported a live in an open circular plastic tank to Port Harcourt, over a distance of 40 km by road. Their blood samples were collected again after the transportation. The results obtained indicated a significant reduction (p<0.05) in mean values of Hemoglobin (Hb), Packed cell volume (PCV), Red blood cell, (RBC), Mean Corpuscular Hemoglobin Concentration (MCHC), Mean Corpuscular Hemoglobin (MCH) and Thrombocytes. The number of White Blood Cell (WBC), Mean Corpuscular Volume (MCV), Neutrophils, (Neut) Lymphocytes (Lymp), and Monocytes (Mon) increased. The variations in these blood parameters were more pronounced in adult fish than the juveniles. This study showed that the adult fish are more susceptible to stress than the juveniles.Keywords: Hematology, stress, handling, transportation, Tilapia guineensis International Journal of Natural and Applied Sciences, 5(4): 338-343, 200
