Item Wildlife-human interface: a case study of Yankari national park Bauchi State, Nigeria(2003) Akinyemi, A. F.; Ayodele, I. A.Most of the serious problems facing protected areas in Africa today has a human component. Among the more common problems are human encroachment, unauthorized harvesting of resources, and the conflict between wildlife managers and local people. The study illustrates the major wild Animals, agricultural and livestock pest in the study area and the attitudes of the farmers/villagers to wild animal species. A land-use planning system that incorporate a floating zoning system which ultimately merge with a permanent zoning system with range of vegetation such as multipurpose trees and shrubs (MPTS) around the park will allow traditional grazing and avoid conflict with local people.Item Prospect of conflict resolution between farmers and nomadic fulanis in Kainji lake national park(2003) Akinyemi, A.F.The study analysed the activities of Nomadic Fulanis in four villages; Banibafu, Mazakuka, Faje and Kere located within the buffer zone of the Kainji Lake National Park. The data was obtained by the administration of questionnaires and personal interviews with farmers, nomadic Fulanis and Park guards. The study clearly identified the routes of nomadic herdsmen from Kebbi to Oyo States and the need for a pasture corridor in other to ensure harmony between all the stakeholders. The nature of the property-rights regime under which the pasture was held was also found to provide sufficient basis for drawing valid conclusions concerning users behaviour, as well as, the consequence of such uses.Item Comparison of economic feasibility and sensory characteristics of giant land snail with selected bushmeats(2014-06) Oduntan, O.

B.; Olukunle, O.Fisheries and aquaculture contribute significantly to food security and livelihood; therefore, fish and fish products are projected as being among the most widely traded foods. Fish like other animals has requirement for essential nutrients in order to grow properly. Such essential foods are available in the wild for fish to forage extensively to meet their body needs. The variable factors such as climate change, environment, season of the year and location among others determines the abundance and search for these foods. These factors modifies aquatic environment and make it difficult for fish in the wild to forage adequately. Therefore, enough food in the form of artificial diet is required to furnish fish with the nutrients it need out of its natural environment for optimal growth. However, most of the challenges facing the formulation of feed are on the affordability, ready acceptability and bioavailability for fish optimal growth. Therefore, trace minerals which are needed in minute quantity at a time for the general health maintenance and growth of an animal offers a soft landing to this challenges; however, their deficiency perturbs the wellbeing of the fish. Zinc has been recognized to play a vital role in almost every aspect of living system either directly or indirectly. The biochemical components of fish diet that needs varying in terms of percent inclusion to render the protein in feed more bioavailable should be encouraged. The objectives of this study includes determination of the; required dietary zinc inclusion that is essential for juvenile African catfish Clarias gariepinus growth, serum biochemical profile of African catfish juveniles post feeding response to growth, and haematological responses of African catfish (Clarias gariepinus) to graded levels of zinc nutrient. Growth performance, serum biochemistry and physiological response to graded levels of practical dietary zinc fed to African catfish (Clarias gariepinus) juvenile were investigated. Water quality was monitored throughout the period of the study and the results showed that all parameters were within the required and tolerable ranges for catfish. The mean weight of fish fed dietborne zinc nutrients revealed that there were no significant differences in growth responses to graded levels of dietary zinc inclusions of 0, 5.46, 10.96, 16.40, 21.86 and 27.33mg Znkg-1 . The results for the mean weight revealed that there are no significant variations in mean weight since P>0.05. However the mean weight for the diet increased with respect to dietary zinc inclusion (Figure 1). The SGR, FCR, GFCE, F.I and RGR, also showed no significant variations among fish fed. The PCV revealed that there are no significant variations among the values for the fish fed with Diets 3, 4 and 5. The serum biochemistry revealed significant variations in the serum total protein (T,P) among fish fed on all the Diets, with the highest values in fish fed Diets 4 and the minimum values in fish fed Diet 2. Fish fed dietary zinc had slightly altered haematological and serum biochemistry in response to dietary zinc.Item The growth performance and survival of Clarias gariepinus fry raised in homestead concrete tanks(Academic Journals Inc., 2012) Olukunle, O.Fertilizer application in earthen ponds has been used as a low-cost method of sustainable aquaculture production. This study was carried out to investigate the growth response of African catfish fry, Clarias gariepinus in three different culture media in homestead concrete tanks. The water in the control (T1) was not treated while T2 and T3 were treated with poultry droppings and soy bean milk filtrate, respectively. Nine hundred catfish fry weighing averagely 0.67-0.69 g were randomly allocated to the 3 treatments in equal number. In each tank (2x3x1.5 m) were suspended, 3 net cages each of dimension, 1x1x1 m containing 100 fry. The fish in tank 1 (control treatment) were fed fish meal from the start at 5% of their body weight and four times daily. The other treatments were not fed at all for the first 7 days. Feeding with fishmeal commenced for treatments T2 and T3 on the next 8-14 day. The weights of the feed were adjusted after weekly weighing of the culture media for phytoplankton composition. The best weight increase was recorded in T1 (2.33 g). The highest survival rate was in T3 (98%). Treatment T3 (11.56±1.14x103) generated higher concentrations of most of identified zooplanktons than treatments T1 (5.39±0.73x103) and T2 (12.78±0.98x103). These zooplanktons were absent in treatments T1 and T2. The result indicates that fertilizing the culture medium using soybean milk filtrate or poultry droppings improved the growth and of C. gariepinus.Item Effect of partial replacement of soybean meal with jackbean (Canavalia ensiformis) as an alternative plant protein in the practical diets of cat fish (Clarias gariepinus)(2015) Olukunle, O. A.; Oshoke, O. J.; Idowu, O. G.This study assessed the potentials of Jackbean seed meal (JBSM) for partial replacement of soybean in diets of Clarias gariepinus. Hence, five diets were formulated at 40% crude protein level as Soybean in control diet (CD) was replaced progressively at (5%, 10%, 15% and 20%) by JBSM in test diets TD1, TD2, TD3, TD 4 respectively. The Jackbean seeds were treated by dehulling, soaking in ash and followed by boiling to reduce the anti nutritional content (canavanine) present in the seeds. Fifteen plastic tanks of (37 liters) containing 25 liters of water was used for growth trial. Each treatment contained 15 fingerlings with an average weight of 6.44 ± 0.1g in three replicates per treatment. Test fish in each tank were fed 5% of their biomass twice daily for 84days. At the end of the experiment proximate composition and growth parameters were analyzed. Result showed that fish fed TD 1 (5% inclusion level) and TD2 (10% inclusion level) compared favourably with the control diet (P ? 0.05). Fish fed control diet had the best specific growth rate (0.54) and feed efficiencies (Protein Efficiency Ratio (PER)= 0.41 and (Food Conversion Ratio, FCR= 6.57). However, considering the results of the statistical analysis used to compare the difference between the means of the different treatment, TD1 (5% inclusion level) compared most favourable with the control in terms of mean weight gain (8.87), specific growth rate (0.39) which was significantly different (P ? 0.05) from other treatments, PER from CD, TD3 and TD4 which are not significantly different (P ? 0.05) from TD2, and FCR (9.41) which was not significantly different (P ? 0.05) from CD but significantly different (P ? 0.05) from TD2, TD3 and TD4. From the results of this study, it shows that 5% of soybean in the diet can be replaced with JBMS without any adverse effect on the growth performance.Item Fishery resources(2011) Olukunle, O.
