Technical Assessment on the Operational Performance of Fish Pond in Lagos State, Nigeria
Journal Title: Annual Research & Review in Biology - Year 2016, Vol 10, Issue 3
Abstract
Technical factors that have potential influence on the performance of fish ponds in Lagos State were assessed. Questionnaires and on-the-spot assessment were used for collecting information on pond construction materials, water sources and pond operational problems. Variations in pond water depth during wet and dry seasons were measured using a levelling staff. Physical and chemical properties of soil and water samples were determined in accordance with the American Public Health Association standards. Data were analysed using descriptive statistics. Seepage occurred in 77.8% of the ponds. Also, 80% of the ponds experienced between 20.0 and 81.0% reduction in water depth during the dry season and 18.0 to 34.0% increase in water depth during the rainy season. Soil pH (6.2 – 6.7) was within acceptance limits, Soil permeability (6.2 – 24.9 mm/hr) exceeded the permissible value 4 mm/hr. Nitrogen (20.20 – 29.30 ppm) and phosphorus (1.93 – 6.57 ppm) contents for different soil locations were less than the recommended values of 50.0 and 9.0 ppm respectively. Nitrogen (0.05 – 0.1 ppm) and Phosphorus (0.06 – 0.09 ppm) contents of the water sources were less than the recommended value of 2.0 ppm. These are indications that the soil locations and water sources were not suitable for pond construction and productivity. Improper location and construction on unsuitable site resulting in pond seepage coupled with poor quality of water supply were the major technical factors that could inhibit fish pond performance in Lagos State.
