    Description: Kainji Lake is a man-made Lake and is impounded in 1968 to generate hydroelectric power. The Lake also offers opportunities for developmental projects like Fisheries and Irrigation. Lake Kainji receives organic waste through husbandry operations in which the cattle defecate into and around the bank of the Lake. Other sources of pollution include runoff from farms, bathing and washings in the Lake. Surrounding villages e.g. Tarda and Musawa used the Lake as source of raw drinking water and also for other domestic purposes. Bacteriological quality of fish and water from the Lake is carried out as well as that of cow dung by using primary isolation media and biochemical analysis. Physico-chemical parameters of water from the Lake is also determined. Total viable bacteria count and total coliform count of the water range from 3.4 x 104 to 03.8x 106 Cfu/ml and 1.4 x 103to 2.1 x 105Cfu/ml respectively. Cow dung has total coliform count of 6.9 x 105 while fish gills has total coliform count of 1.6x103cfu/g. Bacteria species such as Escherichia coli, Salmonella typhi, Aeromanas hydrophila, and shigella species were found in the water body. Escherichia coli, Aeromonas hydrophila, and Salmonella species were found in the fish samples. Escherichia coli, Aeromonas hydrophila, Shigella species and Salmonella species were isolated from cow dung. Physicochemical Parameters such as DO, BOD and N03-N range from 4. 7 to 5.2mg/l, 0.2 to 0.9mg/1 and 7.0 to 9.3 mg/l respectively. This result shows that Kainji Lake is an intermediately polluted water. It is therefore necessary that cow dung used for fertilization of fish ponds should be screened for pathogens before use. It is also recommended that pollution of surface water bodies through human activities should be discourage by legislation on water pollution.

    Description: Sixteen (16) weeks feeding trial in a randomized design with three replicates was conducted to study the response of 180 Oreochromis niloticus fingerlings to baobab pulp as a source of vitamin C. They were fed a basal diet without supplemental vitamin C in the first 2 weeks of conditioning to deplete some stored acrobate. Diets supplemented with 1008 mgascorbyl-2-monophosphate Mg2+ (AMP) kg-1 diet (diet 1); 84g baobab pulp kg-1 (diet 2) and 168g baobab pulp kg"1 diet (diet 3) were evaluated. There was no significant difference (P〉0.05) in terms of weight gain, feed efficiency ratio, protein efficiency ratio, specific growth rate and survival between the groups fed diets 1 and 3. There was a significant difference between the groups fed diet 2 and either of the other diets. Total ascorbate concentration of the liver was significantly (P〈0.05) higher in the groups fed diet 3. The crude protein content of the final fish was significantly (P〈0. 05) higher in the groups fed diet supplemented with AMP. Interestingly none of the groups exhibited the characteristic symptoms of vitamin C deficiency. The results of this experiment suggest that Oreochromis niloticus was able to obtain vitamin C from the baobab pulp and tend to recommend baobab pulp at a level not less than 168g kg-1 diet in the nutrition of Oreochromis niloticus based on the condition of this study.

    Description: The implications of the abattoir effluents discharge into the Lower Ogun River in Isheri-Olofin area on the abundance of three African fresh water prawns: Macrobrachium vollenhovenii, M macrobrachion and M. felicinum were assessed. Monthly prawn collections were undertaken using a scooping bag net with 0.05mm mesh size at three stations with 100m intervals in each of Ishasi (upstream) and Isheri-Olofin (downstream) areas of the river for 24months (January, 2006-December, 2007). For the 24month period, the upstream (pooled data from stations 1,2 and 3) had M. vollenhovenii of total and mean density of 27,938.33 prawn/m2 and 1164.60prawn/m2 1131.04 respectively, while total and mean M. vollenhovenii density of 5,815.43prawn/m2 and 243.81 prawn/m2 231.45 were obtained in the downstream (pooled stations 4, Sand 6 data). T-test showed the entire upstream to have significantly higher M. vollenhovenii density than the entire downstream (p〈0.05). The entire upstream had higher M. macrobrachium total and monthly mean density (19,092prawn/m and 816.44prawn/m2 1,354.28) than the entire downstream (6,384.47prwn/m2 and 266.02m2524.94) (p〈0.05). Also, significantly higher total and monthly mean density of M felicinum were obtained upstream (20,9S6.S0prawn/m2 and 873.46prawn/m21615.06) than downstream (10,9668.11prawn/m2 and 461.16prawn/m2975.19) (p〈0.05). The significance of the decline in abundance of each of the three Macrobrachium prawn species in the downstream area was discussed.

    Description: Finfish and shellfish fauna composition of the old Owena reservoir, established over 46 years old for drinking and domestic use in Akure metropolis, Ondo town and other villages were re-examined in 2008/2009 to assess long-term changes in relation to activities in the catchment which have included, another new reservoir constructed up stream in 2006. The pre-stocking assessment of the fauna of the newly constructed reservoir was determined. The degree of change between years in total abundance, numbers of taxa and community composition varied considerably between the two sites. These observed differences may be related to increased flora cover in the well established old reservoir, while the new reservoir is still empty with only tilapia as the predominant fish without established aquatic plants. Only one species of fresh water gastropod was found and identified in the new reservoir, while two species of gastropods and one bivalve were identified in the old reservoir. They were found in abundance within their standard length size range of OA2. - 12.5cm. A positive correlation (R2=0.9227) was obtained for samples collected from the' old reservoir, those from the new reservoir gave a contrasting value (R2=0.20 1).

    Description: Four different shrimp species; Penaeus monodon, Macrobrachiwn vollenhovenii, Macrobrachium felicinllm, Parapenaeopsis atlantica were collected from Lagos and Ondo states coastal waters and examined. The length (em), weight (g), head weight (g), tail weight (g), number of upper and lower rostrum teeth were determined. The species varied differently in weight ranging from 100.70g, 48.30g, 12.l0g and 9.20g for each species respectively. Length of 27.60cm, 18.l0cm, 15.70 and 10.40cm were recorded, head weight of 33.90g, 24.90g, 4.40g, 7.40g. Tail weight; 67.30g, 24.l0g, 7.70g and 3.20g were recorded. While the number of upper and lower rostrum teeth in P. monodon, M. vollenhovenni, P. atlantica, and M. felicinum were; 7-10/1-3, 11-14/3-5, 5-1110, 12-16/3-5 respectively. Penaeus monodon had the highest weight (l00.70g) but had rostrum teeth of 8/3. The result obtained for the species in homogenous subsets revealed that in weight (g), M. felicinum and P. atlantica falls into the same subset, while M. vollenhovenii and P. monodon fall into different subsets. In the length (em), all four species fall into different subsets. In the head weight (g), P. atlantica and M. felicinum fall into the same subset while M. vollenhovenii and P. monodon fall into different subsets. In tail weight, it was also applicable. In number of teeth on the upper rostrum all four species fall into different subsets and in number of down rostrum P. atlantica and P. monodon fall into different subset while M. vollenhovenii and M. felicinum fall into the same subset.

    Description: The effect of selenium supplementation into diets of Heterobranchus longifilis fingerlings was investigated using a completely randomized design with triplicates in a mini-flow through experimental system. 245 fingerlings (mean wt., 1.5~c0.23g) were stocked and fed either normal (Basal) diet (Control group) or diets supplemented with 0.16, 0.24, 0.32 or 0.64 mg sodium selenite Kg-I Selenium addition to the diets and fed to the fish caused a significant increase (P〈0.05) in weight gain and fingerlings growth rate was accelerated by 18-22% compared to 17-18% in the control group. There were significant differences (P〈0.05) in survival rate between treatments, indicating that diets are likely to be responsible for increased survival rate, observed in fish fed diets supplemented with 0.24 and 0.32 mg Na2 Se03 5H2O kg-1 diet. Results indicated that a diet supplemented with, 0.24 and 0.32 mg of sodium selenite Kg-1 diet is important for growth and survival of H. longifilis fingerlings.

    Description: An investigation was conducted on the morphometric features and proximate body composition of rocky freshwater prawn, Caridina africana occurring at Erin-Ijesa Waterfalls in Osun State, Nigeria. The adult prawns were collected at the first layer of the Waterfalls using scoop nets and locally fabricated sieves because of the shallow nature of the water body and tiny size of the species. Morphometric features were measured using measuring board and Vernier calipers while the proximate analysis was determined by atomic absorption spectrophotometry in the laboratory. The morphometric variables placed the species correctly into the Infra order Caridea and family Atyidae because the first and second chelipeds were shorter than the remaining three pairs of walking legs. Male prawns were significantly bigger (p〈0.05). than the females as revealed in the morphometric features. The proximate analysis showed that C. africana is composed of 58.79% protein, 5.42% lipid, 11.56% carbohydrate, 14.7% ash and 0.21 % crude fibre. The micro-nutrient composition included iron, zinc, copper, nickel and cadmium. The values for these nutrients make the study to suggest that C. africana could be a nutritive food bio-material for humans and other livestock nutrition especially the fin-fish aquaculture programme.

    Description: Tilapia is the second leading aquatic crop globally, next to carps and its production has increased tremendously within the last decade. Its production is however affected by stunting, a phenomenon brought about by overpopulation due to precocious reproduction under mixed sex culture system. Several methods such as use of predatory fish, hybridization, polyploidy and sex reversal, using methyl testosterone have been employed w1th different degrees of success. This paper reviews the use of methyl testosterone in sex reversal of tilapia and its consequent effects on fish, man and environment. It established the preference of all-male tilapia due to better and more uniform growth under culture system. It has been demonstrated that the hormone does not have any adverse effect on fish flesh after cessation of treatment of tilapia fry. In like manner; ingestion of fish produced by sex reversal does not therefore harm man. However,one is not too sure of the effect of the hormone or its by- products on vital organs (liver, kidney, pancreas and gills), metabolic profile and nucleic acids. This may also affect muscle building and perceived libido-enhancement in man. On the environment, the steroid is either biodegraded or mineralized. It must be stated that escapee from tilapia hatchery into the natural water may, however, alter the dynamics of the environment due to unforeseen consequences.

    Description: A feeding trial was conducted to determine the effect of biscuit waste meal on the growth performance and utilization of Clarias gariepinus juveniles. A total of 300 juveniles of average weight 8.85g were randomly divided into 5 Treatments, each with three replicates. Twenty juveniles were distributed into fifteen happas (0.7m3) and each happa was suspended to 3/4 of its volume using kuralon ropes carefully tied round the bamboo poles across the concrete tanks. Five diets containing 40% crude protein were formulated in which maize was replaced with biscuit waste meal at Treatment diet 1 (TD1) 0%, 25% (TD2), 50% (TD3), 75% (TD4), 100% (TD5) levels.The juveniles were fed at 3% body weight per day for 10 weeks. It was recorded at the end of the experiment that biscuit waste was most suitable as an energy supplement when incorporated at 25% replacement (TD2) with maize. TD1 had the highest weight gain followed by TD2, TD3, TD4 and TD5 respectively. There were no significant differences (P〉0.05) in the growth response in TD1 (0%), T0D (25%) and TD3 (50%). It is therefore concluded that biscuit waste meal is a cheap source of non conventional energy source which can be used favorably to replace maize (25% inclusion level) as an energy source in the diets of Clarias gariepinus.

    Description: Heterobranchus longifilis juveniles (93.42 - 147.77g) used for this study were product of an indoor experiment in glass aquaria transferred to outdoor tanks. This study is therefore, a continuation of the indoor study using the same feed for the fish outdoors for 230 days. They were stocked in ten concrete tanks, of sizes 2m X 2m. The fish were stocked according to the number harvested from the indoor experiment for each treatment. The experimental diets were prepared with fish meal, soybean, groundnut cake, wheat offal, yeast, premix, starch, vitamin C and Vitamin B-complex to meet the requirement of H. longifilis. The analyzed crude protein in each diet was 42.56%, 43.32%, 4369%,43.86% and 43.98%. There was significant variation (p〈0.05) in the Mean Final Weight (MFW), Mean Weight Gain (MWG), Protein Efficiency Ratio (PER), Specific Growth Rate (SGR) and Percentage Survival (PS). The survival of the fish was highest with the fish fed 2g yeast/I00g of diet and this was not significantly different from fish fed 1g yeast/ 100g diet. The cost of production of one kilogram of fish using varying levels of S. cerevisiae in diets varied significantly (p〈0.05).
