Community Based Fishery Management: A Case Study Of Acadja Method Of Fishing On The Badagry Creek, Ogun State, Nigeria

The objective of the study was to elucidate and analyze key conditions for communal acadja system on the Badagry creek in Ipokia Local Government Area of Ogun State. A sample size of 120 respondents was used for the study. Data were collected with structured questionnaires and analysed with the use of descriptive statistics such as means and percentages. The study revealed that most (86.9%) of the respondents were fully involved in the communal acadja with only 9% of them participated primarily for income generation while the larger percentage of the respondents involved for subsistence. It was observed that the fishers have some degree of tenure on the area of installation because of traditional regulatory mechanism in place. However, some constraints faced by the fishers as a result of implantation of acadjas include abandon of certain fishing gears, changing of fishing grounds, small fishing grounds and destruction of fishing gears. It was therefore recommended that acadja systems should be planned and implanted in the context of multiple uses of water body that integrated acadja systems with fishing and migration.

Single Feature Polymorphism Discovery in Rice

The discovery of nucleotide diversity captured as single feature polymorphism (SFP) by using the expression array is a high-throughput and effective method in detecting genome-wide polymorphism. The efficacy of such method was tested in rice, and the results presented in the paper indicate high sensitivity in predicting SFP. The sensitivity of polymorphism detection was further demonstrated by the fact that no biasness was observed in detecting SFP with either single or multiple nucleotide polymorphisms. The high density SFP data that can be generated quite effectively by the current method has promise for high resolution genetic mapping studies, as physical location of features are well-defined on rice genome

Mortality in sheep and goats and rearers’ patronage of veterinary clinics in Ogun state

The study area was the entire Ogun State. Data collection was done with the aid of structured questionnaire. A minimum of 3-5 towns/villages were randomly sampled per local government. 15 questionnaires were administered in each local government. At the time of study, the state consisted of fifteen local governments. The field study spanned between mid-January and May, 1992. Mortality was caused by more through diseases of multiple causes (39.09%), viral causes (25.36%) and bacteria causes (13.40%) while many farmers (72.28%) hardly patronize veterinary clinics but a few (27.72%) do patronize the veterinary clinics. Among the factors identified to have caused reduced patronage of veterinary clinics and call on veterinary doctors are the unavailability of government and private veterinary clinics in the farmers’locality, ignorance of the farmers, high cost of veterinary services, lack of capital while some farmers are not even aware that there are veterinary clinics. In instances where veterinary clinics were found in farmers’ locality, it is far from the farmers. Lack of technical skills of how to rear these animals has made farmers to only treat animals more during disease outbreaks (66.17%).There is a need for veterinary clinics to be located close to the farmers especially in Egbado, Ijebu and Egba of Ogun State. There is also a need for publicising such clinics and their services to create awareness among the farmers.Keywords: Sheep and goat;, veterinary clinics, mortalit

Effect of age, sex and local government area on linear body measurements of WAD goat in Ogun State, Nigeria

One hundred and twenty West African Dwarf goats were used in this study. Observations were made from twelve different towns in Yewa North, Yewa South and Abeokuta North Local Government. West African dwarf goats were evaluated for phenotypic variation at different ages ranges from 1, 2 and 3 years. Variations in live weight and body measurements such as height at wither; body length, heart girth, fore limb length, hind limb length, face length, ear length, ear width, hip width and tail length were taken. The local government areas significantly (P<0.05, 0.001) affected body length, fore limb length, ear length, ear width, hip width and live weight. Age and sex significantly (P<0.01) affected all the body measurements. The mean live weight by age groups are 6.61 + 0.31kg, 13.10 + 0.60kg and 20.18 + 0.95kg for ages 1,2 and 3 respectively. The coat colour varied from black, brown, grey to white in WAD goats. Some colours were in patches, some uniform while others were spotted

Preliminary observation of genital secretions, growth rate and behaviour of caged cane rats

Cane rats are large terrestial rodents which have the potential to increase animal protein intake. There is paucity of information on the genital secretions and growth rate of caged cane rats. This study observed the genital secretions, growth rate, feeds, feeding and the behaviour of caged cane rats. When animals adjusted to cage conditions, they received feed (sugar cane) directly orally. Some of the cane rats captured around the stream did not adjust to the cage as they died 10 days after capture from the wild. The doe attained puberty at age 11weeks (2months 3weeks). At this age, reproductive activities commenced in the doe with a slight opening of the vulva and the presence of colourless mucous fluid in the vagina. At 11weeks, the vulva was opened for 3weeks plus 6days and by the 4th week the crust had covered the vulva. The vulva opened for a minimum of 1 week and maximum of 4 weeks. The vulva closed for a minimum of 3 weeks and maximum of 4½ weeks. During the intermittent opening between closures, there were always colourless mucous secretions or sometimes thick yellowish mucous and the buck did not chase the doe for mating. The buck withdrew completely from the doe. When the vulva opened and the vagina was dried, the buck made a chase of the doe. Environmental influences (rain splashes) do not affect the opening and closing activities of the vulva in the doe. At between 18 - 27 weeks, the doe had a better growth rate in cage and had gained 0.5kg. This study has revealed that cane rat has an estrous period hence it is a break through for the cane rat breeders and farmers. Breeders/farmers need not to keep the buck with the doe until it kits thus they would be able to maximize the useage of their breeding buck to serve many doe. This also calls for other studies on the physiological variations to be carried out in the intra and inter populations of cane rat.Key words: cane rat, feeding, mucous, vulva, vagin

Some Haematological And Serum Biochemical Parameters Of Goats Fed Cynodon nlemfuensis, Spondias mombin and Gmelina arborea Based Diets

Haematological and serum biochemical analyses of West African Dwarf goats fed three different diets was carried out. Eighteen (18) growing bucks aged 7 – 7.5 months with a mean live weight ranging between 6.67 – 7.02 Kg were randomly allotted to three dietary treatments comprising six (6) animals per treatment. A 3 x 4 factorial experiment in a completely randomised design (3) different diets (A, B and C) and four collection periods (day 0, 21, 42 and 63) of blood samples was used. The animals were housed in wood shavings bedded individual pens (1.5 x 1.2 x 1.0) m3 and fed 0.30 Kg/head/day of the diets. The Cynodon nlemfuensis based diet served as the control (diet A) while Spondias mombin and Gmelina arborea based diets served as dietary treatments B and C respectively. Prior to the commencement of the feeding trial, blood samples were collected (day 0) by jugular venipuncture from the animals and at 21 days interval, during the trial which lasted sixty three (63) days. Collected blood samples, which were placed in well labeled heparinized bottles (2.5ml) and into anticoagulant-free well labeled plastic tubes (2.5ml), were analyzed within four hours of collection for Erythrocyte, Packed Cell Volume (PCV), Haemoglobin(Hb) and total leucocyte count. Total serum protein, albumin and globulin, PCV and white blood count (WBC) were not significantly (P>0.05) influenced by the dietary treatments and collection periods. However significant differences (
