Item Antioxidant and antifungal effect of fresh ginger (Zingiber officinale) on the shelf life of smoked catfish(The Faculty of Agriculture, Obafemi Awolowo University, Ile-Ife, Nigeria, 2020) Abubakar, M.I.; Adeshina, Ibrahim; Ogunniran, G.; Abdulraheem, I.; Ezeig, N.O.; Omoniyi, I.T.The antioxidant and antifungal effects of ginger paste extracted from fresh ginger on smoked catfish were examined for a 21-day storage period at room temperature (25-30oC).The ginger paste was extracted from fresh ginger by scrapping off the outer coat, ground and blended. Eighty fish samples were gutted and washed thoroughly after which they were divided into five groups of sixteen.Each group was spiced with ginger paste at 10g, 20g, 30g and 40g respectively while the control batch was not spiced. The fishes were then smoked in a smoking kiln for 8hrs. The Superoxide dismutase activity and fungal isolation analyses were carried out to investigate the antioxidant and antifungal effect of ginger paste on the fish samples.The lowest superoxide dismutase and peroxide values(0.64 μ/mg and 7.483 mEq/kg respectively)were recorded in the group of catfish spiced with 40g of ginger (at day 21) and control respectively while the highest Superoxide Dismutase (1.92μ/mg) and Peroxide (9.141 mEq/kg) values were recorded in the group of catfish spiced with 30g of ginger at Day 21. Mucor circinelloides, Rhizopus stolonifer and Aspergillus niger were isolated from the spiced catfish samples The result revealed that catfish samples spiced with ginger paste had lowest mould count compared with the control group. Recommendation was made for the use of 30-40g of ginger to spice 1kg of catfish in order to reduce microbial growth on them.Item Comparative studies on the effect of ovaprim and coconut water (Cocos nucifera) on the hatchability of Clarias gariepinus(Federal University Gashua, 2015) Adewale, A.Y.; Adeshina, IbrahimThe effect of ovaprim and coconut water (Cocos nucifera) on the fecundity and hatchability of Clarias gariepinus were investigated. A total of eight broodstocks make up of males (550-900g) and four females (500 – 517g) were selected for artificial spawning using different treatments of hormonal dosage of ovaprim, coconut water, mixture of coconut water and ovaprim and control (0.30ml/kg-0.26ml/kg and 0.00ml.kg) respectively. The eggs hatched after 25 hours at temperature 230C – 270C. The effectiveness of the coconut water induced in C. gariepinus was assessed using percentage fertilization and hatchability as indices. However, mixture of coconut water and ovaprim respond effectively on C. gariepinus with fertilization 50.66±10.00 followed by ovaprim 38.66±7.63 and hatchability 50.00±10.00 followed by ovaprim 38.66±18.92. There was no significant difference (P <0.05) in mortality in all the treatments.Item Effects of different hormones on the growth performance of Clarias gariepinus(Kebbi State University of Science and Technology, Aliero, 2016) Adeshina, Ibrahim; Adewale, A.Y.; Dalhatu, B.JThe effects of different hormones on the growth performance of Clarias gariepinus were investigated. A total of eight broodstocks weighing between 500 and 900g (4 males and 4 females) were selected for artificial spawning using different treatments of hormonal dosage of Ovaprim, coconut water, mixture of coconut water and ovaprim and control (0.30ml/kg-0.26ml/kg and 0.00ml/kg) respectively in replicates. The result shows that the mean weight of egg stripped was higher in fish injected with coconut water + ovaprim with 80g. Mortality was highest in first seven days in fish treated with ovaprim (73), seven to fourteen days in fish treated with coconut water (60) and in twenty-first to thirtieth days in fish eggs stripped from fish treated with coconut water+ovaprim (5). Fry from the fish treated with coconut water+ovaprim had highest initial weight gain, final weight gain and weight gain of 1.44±0.91, 12.31±9.30, and 10.87±2.89 respectively. There is significant different in the initial weight, final weight and weight gain of the fry (P<0.05). Fry from the fish treated with coconut water +ovaprim had highest in ADG, SGR, FCR, and PER with 0.36g, 0.07g, 0.20g, and 0.21g. Dissolved oxygen was between 5.8 and 7.8mg/L, 22.5 and 27.80C, and 7.25 and 7.33. It can be concluded that uses of coconut water+ovarprim at 50% mixture is adequate to improve growth performance of the fry which will also minimize the cost of seed production.Item nalysis of conflicts and security issues among informal cross-border fish traders in Okpara, Oyo State, Nigeria(Department of Mass Communication, University of Maiduguri, Maiduguri, Nigeria, 2013) Balami, Dahiru Hassan; Adeshina, Ibrahim; Agbeja, Yetunde EniolaItem Occurrence of Klebsiella Species in cultured African catfish in Oyo State, South-West Nigeria(Nigerian Veterinary Medical Association, 2016) Adeshina, Ibrahim; Abdulrahman, S.A; Adewale, A.Y.Over the years, the increase in population, incomes, and demograph has lead to the increase in the consumption of fish as a result of its nutritional values. Clarias gariepinus is the most cultured fish species in Nigeria and attracts significant economic value making it a species of interest. Fish is capable of habouring diseases and therefore, must be safe and free of infectious pathogens if aquaculture should fulfill its potential. Infectious disease has being one of the major causes of death worldwide in recent times. Klebsiella species in the family of enterobacteriacea causes urinary tract infections, pneumonia, septicemias and soft tissue infections in human. They are opportunistic pathogens found the gastrointestinal tract of the host and spread rapidly thereby capable of causing nosocomial outbreaks. The study examined the prevalence of Klebisiella species in fish tissues in Oyo State, Nigeria. A total of seven hundred and fifty-six (756) fish organs from one hundred and eight (108) fish were examined for Klebsiella investigation. Fish of body weight ranges between 300g to 1300g were used for this study using stratified methods. The samples were examined using standard methods, biochemical characterization methods were employed in this study and data obtained were analysed using descriptive statistics. The results show that all the 66 isolates were gram-negative, did not haemolysis sheep blood, catalase positive, oxidase negative, non-motile, and ferment lactose, sucrose and mannitol sugars. Percentages of klebsiella species occurrence were 22.22% in forest zone and 40.72% in savannah zone. Fish with total length 51-60cm had highest incidence (52.17%), and body weight of 601-900g had highest incidence (57.14%). Generally, skin, gill, liver and muscle were the major location of Klebsiella species occurrence ranges from 11% to 14.81%. Therefore occurrence of Klebsiella species in higher in savannah zone than forest zone. The distribution of the klebsiella in fish in Oyo State shows that it is a problem present in fish tissues.Item Preliminary studies on the prevalence of Listeria monocytogenes in Clarias gariepinus and Orechromis niloticus in Ibadan, Oyo State(Faculty of Agriculture, University of Ilorin, Ilorin, Nigeria, 2015) Adeshina, IbrahimPrevalence of Listeria species in Clarias gariepinus and Oreochromis niloticus were examined. Sixty (60) of fishes were randomly selected from commercial outlet in Ibadan. Sex, Total Length, and Weight were determined. Simple percentages were used to analysis the data. The results show that 12 out of 60 (20%) were positive for Listeria species. Male has highest number of infection (18.91%) fishes with average length of 20-30cm had 41.17%, 351-400g had highest number of infection (28.57% ). C. gariepinus (26.67%) shows the higher presence of Listeria species than O. niloticus. There is no correlation between infection and species, sex or length. The result shows high presence of Listeria species and further suggested that there is high risk of contacting listeriosis though the listeriosis outbreak has not been recorded in the study area.Item PREVALENCE, CHALLENGES AND CONTROL OF Listeria monocytogenes IN Clarias gariepinus IN IBADAN, OYO STATE NIGERIA(Kebbi State University of Science and Technology, Aliero, 2015) Bawa, D.Y,; Adeshina, Ibrahim; Ribah, M.I.This study examined the prevalence of Listeria species in fish (Clarias gariepinus and Oreochromis niloticus). The total number sixty (60) of fishes were randomly selected from commercial outlet in Ibadan and examined. Sex, Total Length, and Total Weight were determined in respect to occurrence of Listeria spp. Simple percentages were adopted to analyze the data. The results show that 12 out of 60 (20%) were positive for Listeria species. The three species identified were L. monocytogenes, L. innocua, and L. grayii. Male has highest rate of infection (18.91%), fishes with average length of 20-30 cm had 41.17%, 351-400 g has highest number of infection (28.57%). C. gariepinus shows the highest presence of Listeria spp with over 26.67% (L. monocytogenes 16.67%; L. innocua = 6.67%; and L. grayii = 3.33%) while O. niloticus shows total of 13.33% presence of Listeria species (L. monocytogenes 10.00%; L. innocua = 3.33%; and L. grayii = 0.00%). Isolation of L. monocytogenes in fish (Clarias and Tilapia) in Ibadan in this study indicates that there is high presence of Listeria species and this further suggested that there is high risk of contacting listeriosis in the study area. It was recommended that proper hygiene and cooking to at least 70 oC is recommended since the bacteria can be killed at that temperature. Attention should be given to avoid cross-contamination and re-contamination from the chain, especially ready- to- eat fish such as fried fish, smoked fish and so on.
