Item Analysis of Informal cross-border fish trade in Okpara Market, Okpara, Oyo State, Nigeria(Fisheries Society of Nigeria, 2015) Adeshina, I; Agbeja, Y.E.; Balami, D.H.; Adewale, Y.A.; Yusuf, O.YInformal cross-border fish trade (ICBFT) is one of the ways of bridging the gap created by formal trade to meet citizenry needs. In Nigeria, its extent and manner of operation has not been clearly reported. ICBFT in Okpara market was examined.One Hundred and Twenty questionnaires were purposively distributed to the Cross-Border Fish Traders and responses were analysed using descriptive statistics and Multiple Regression analysis. Results showed that smoked fish was the dominant fish taded with little/no value addition. A kilogram of fish was sold at two-thousand naira per kilogram as agreed by 90% of the traders while every trader sold an average of 100kg (82%) on every market day. The Fish Traders' sources of capital were mainly from personal money (61%) while means of currency exchange were parallel market (75%). There was no formal source of information (95%) and transaction was done through cash, barter and/or credit arrangement (36%). The regression analysis (r=0.941) showed that there was linear relationships between the number, size and price of fish being traded in the market with significant effect on Nigeria's economy. The results indicated that Nigeria is losing much to the activities of Informal Cross-Border Fish Trade which could boost Gross Domestic Product (GDP) if it is recognized,formalized and incorporated into the economy of this country.Item Eugenia cayrophyllata oil as anesthetic in cultured African Catfish, (Clarias gariepinus, Burchell 1822) juveniles(Fedral University Gashua, 2016) Yusuf, O.Y.; Adeshina, I; Adewale, A.Y.The aim of this study was to compare some semen physical characteristics of both wild and cultured Clarias gariepinus broodstocks in order to know their relative economic advantages to farmers. Nine male broodstocks were selected with their weight ranges between 700g to1250g, with total length ranges between 51.50cm to 61.00cm. The fish were sacrificed by spinal transaction, after which the fish were dissected and the gonads were removed. The gonads were examined after weighing, and were evaluated for pH, motility, volume and sperm concentration. Descriptive statistics was used to find their minimum and maximum values. Student t-test was used to analysed the differences of their means. Also, the relationships between semen parameters were tested using the bivariate correlation coefficients of pearson. Significant differences (P<0.05) were observed in semen mean progressive motility (%), pH, volume (ml), weight of gonads (g) of Cultured (88.00±6.96%, 7.22±0.26, 8.01±1.13ml, 4.16±1.59g) and Wild (56.30±42.30, 6.89±0.33, 5.80±0.40, 2.01±1.02) broodstocks, respectively. There was significant correlation (P<0.05) between pH and progressive motility, volume and concentration, weight of gonads and volume of the Cultured broodstocks. There was a significant correlation (P<0.05) between weight of gonads and concentration of both Cultured and Wild African Catfish. The semen quality of the cultured broodstocks was higher than that of wild broodstocks and this may be due to differences in their environment and their feeding conditions. It is recommended that further research should be done on evolutionary and genetic performance of wild African catfish.Item Growth performance and nutrients utilizayion of Macrobranchium vollenhoveni fed diets supplemented with lactobacillus acidophilus(Association of Nigerian Fisheries Scientitis, 2018) Adeshina, I; Adewale, Y.A.; Sani, R.A.; Ajibola, M.M.; Tiamiyu, L.O.; Aderibigbe, Z.O.Performance (growth and nutrient utilisation) of Macrobrachium vollenhovenii fed diets supplemented with Lactobacillus acidophilus were evaluated. Six diets (43%crude protein) were prepared with L. acidophillus which comprised 0, 10', 10,10,10,and 10s CFU/mL fed to 360 M. vollenhovenii (10.02±0.02 g) to satiation for 84days. Weight gain (WG), specific growth rate (SGR), protein efficiency ratio (PER),feed conversion ratio (FCR) and feed intake (FI) were determined using standard methods. Data were analysed using descriptive statistics and ANOVA at p=0.05.The result showed that WG,SGR, PER,FCR and FI were significantly different among the treatments(p<0.05). Highest growth was recorded in prawns fed 10* cfu/mL L.acidophillus based diet. Therefore, dietary 10°cfu/mL L. acidophillus could enhance growth and nutrients utilization of M. vollenhovenii.Item Length-weight relationships and condition factor of four fish species in Lake Tatabu, Niger State, Nigeria(Fisheries Society of Nigeria, 2015) Akinwande, A.A.; Adesina, B.T.; Adeshina, ILength-weight relationship and condition factor of 640 fish populations covering four families, 4 genera and 4 species from Lake Tatabu were studied. The fishes (Synodontis membranaceus, Hydrocynus forskalis,Auchenoglanis occidentalis and Lates niloticus) were obtained from two different fish landing sites along the lake from November 2014- February 2015.The regression constant (a) and allometric coefficient (b) extrapolated from the length-weight relationship W= aL' and condition factor (k) are presented for the four fish species. The b values range between 1.86 -3.17 with mean value of 2.67while the K value varied between 1.05 - 2.89 and with mean value of 1.78. Of the four fish species, Lates niloticus showed isometric growth while the others depicts allometry growth pattern.
