An assessment of the problems of fisheries data collection in Nigeria

This paper reports on a survey, which studied the problems working against fisheries data collection in the country. The purpose of this was to quantify the capacity of the States to effectively collect data needed for planning and development of the fisheries sector and to assess the impact of this on the process of data collection and the quality of the data collected. Four organizational levels of data collection - Enumerator, L.G.A, zone & State - were recognized by the study, but their efficiency is weakened by inadequacies of manpower, budgets & logistics. The magnitudes of these problems vary among the States but their effects are adverse all over. The current efforts of the Federal Department of Fisheries and other stakeholders to strengthen fisheries data collection in the states should be intensified both in magnitude and frequency to be able to achieve adequate capacity for generating adequate data for planning and development of the fisheries sector

Microbiological status of water and fish samples from Jabi Lake, Abuja

Jabi Lake is a natural water body in Abuja Federal Capital Territory (FCT). It was expanded for commercial fishing following relocation of Nigeria's headquarters to Abuja in 1993. Quantitative analysis of microbiological status of water and fish from the Lake was carried out. Samples were collected from the dam site, open water, middle lake and inlet. Result reveal that total coliform count which are indicators of pollution are high (2.0 x 103 cfu/ml, 1.1 x 103 cfu/ml, 1.0 x 103 cfu/ml and 1.1 x 103 cfu/ml for dam site, open water, middle lake, and inlet respectively). Total viable count too is high (9.2 x 103 cfu/ml, 4.9 x 103 cfu/ml, 4.6 x 103 cfu/ml and 4.9 x 103 cfu/ml for dam site, open water, middle lake and inlet respectively). There are no coliform bacteria in the muscle of the fish. High bacterial load is an indication of biological pollution and these calls for restraint on the side of those who are using the lake as site for refuse dump
