ABSTRACTA comparison of the growth of the Nile tilapia (Oreochromis niloticus)fingerlings fed with Blue crown® and Skretting® commercial feeds was studiedfor a period of 8 weeks. A total of sixty fingerlings of Oreochromis niloticuswere used. The treatments showed significant difference (p0.05)between the two feeds. Some water quality parameters assessed during theexperiment indicated that only the dissolved oxygen was significantly differentbetween the two treatments (p
ABSTRACT Trachurus trachurus (Atlantic horse mackerel) was smoked with two different fire woods Di'alium guineensis and Pentaclethra macrohylla and sawdust using a traditional smoking kiln and a constructed sawdust stove sited in the fish farm of Michael Okpara University of agriculture Umudike. The frozen fish sample was weighed, eviscerated and washed properly with clean water. During smoking the temperature of the heat was taken, duration of smoking period was also noted in smoking p...
ABSTRACT A 96 hour bioassay was conducted to determine the toxicity of cassava effluent to Claries gariepinus juveniles and its effects on the gills and liver as well as on some blood parameters such as packed cell volume (PCV), Red blood cells (RBC), White blood cells (WBC), Haemoglobin concentration (Hb) and their counts. Juveniles of C. gariepinus of the same age and size showed varying degrees of hyper-activity, mortality, stress and lesions to different concentration of cassava effluent...
Fish a good source of Protein is susceptible to contamination because of their soft tissues and the aquatic environment. They can be contaminated at any point from farm to fork via many means. It is a major public health concern that consumers assume that fish caught fresh from the wild or processed is totally safe. This study therefore seeks to evaluate the human safety in consuming freshly caught fish from dams in Ekiti State and processed fish from Ekiti environs by assessing and comparing...
ABSTRACT A total number of 60 Tilapia zillii specimens were collected from Egbe darn Gbonyin local government in Ekiti West for 25 days. Morphometric measurements taken in the laboratory include total length, standard length, body weight, body depth, dorsal fin length, caudal peduncle length, head length. fork length, and pre-dorsal fin length. Total number of 34 female Tilapia zillii were collected as 26 number of male Tilapia zillii were collected from the study area. The maximum total leng...
ABSTRACT The study evaluated the toxicological effects of paraquat on Oreochromis niloticus fingerlings. Two hundred and sixteen (216) fingerlings (Average weight: 7.50g) were purchased from a local farmer in Ikole-Ekiti, Ekiti State, Nigeria and were transported to the Wet Laboratory of the Department of Fisheries and Aquaculture, Federal University Oye-Ekiti, Nigeria and acclimatized for two weeks. After range finding test, the fish were exposed to acute concentration of 2.96 mg/I, 3.3lmg...
ABSTRACT The aim of this study was to evaluate the effects of graded levels 1.3 %) of ginger (Zingiber officinale, Roscoe) (0%, 0.1%, 0.4, 0.7%, 1.0% and 1.3 %) as feed additive in the diets of Clarias gariepinus on growth performance and haematological parameters. This study was carried out to evaluate ginger (Zingiber officinale) for ten weeks to study its effects on Clarias gariepinus. Thus, two hundred and seventy juvenile catfish (Clarias gariepinus) were fed on various levels of supp...
ABSTRACT. The study examined the effect of battery waste on African catfish, Clarias gariepinus. Massive spent batteries when disposed indiscriminately constitute nuisance and cause resource waste as well as environmental pollution to the ecosystems. The fish were exposed to five different concentrations as T 1 5g,T2 l Og, T3 15g, T4 20g, T 5 25g,and the control as T0 for four days and later left for four weeks as possible bio-remediation. Physicochemical parameters and heavy metals were an...
ABSTRACT An 8 weeks feeding trial of different percentage inclusion of Thevetia peruviana seed meal in the diet of Clarias gariepinus was conducted. The experimental diets were Ctr0TSM, 5TSM, 10TSM 15TSM and 20TSM percentage replacement of plant protein in the control diet. The experimental design is a complete randomize design in which there were three replicates for each of the treatment. And the fish were stocked 10 per each tank, fed experimental diet two times a day of 5% body weight...
ABSTRACT Eight weeks trial was conducted to study the effect of dietary inclusion of autoclaved castor seed meal on growth performance, body composition and haematology of Clarias gariepinus fingerlings. 150 Clarias gariepinus fingerlings were divided randomly into 5 groups of ten fish/tank each to five treatments. The experimental design is a complete randomize design in which there were three replicate for each of the treatment. The experimental diet which were designated 0%, 10%,15%, 20%, ...
ABSTRACT Three different chemicals: fonnalin, hydrogen peroxide and potassium permanganate were used for intermittent prophylactic treatment of Clarias gariepinus fingerlings (2.43±0.04) for 10 weeks. The experiment was made up of four treatments: Tl (Control), T2 (Potassium permanganate at 2ppm concentration), T3 (Hydrogen peroxide at 1600ppm concentration), and T4 (Formalin at 100Oppm concentration) with each treatment having 15 fingerlings of catfish. Each treatment was in triplicates. ...

ABSTRACT For the course of this study, a total of 100 specimens of Hydrocynus forskahlii were collected at different stages of life from Ureje Dam, Ado Ekiti, Ekiti State, between the period of .September and October, all fish samples of Hydrocynus forskahlii was carefully examined to avoid damage to any of the morphometric characteristics of the fish. The measurements for (he morphometric characteristics of each of the investigated tiger fish specimen was carried out in the Fisheries and A...
ABSTRACT This study evaluated the nutritive and organoleptic properties of three fish species processed using three methods, sun-drying, smoking and trying in Ailara fishing community of Asa Reservoir in Kwara State. Sun-dried Oreochromis niloticus, Clarias gariepinus and Hydrocynus forskahlii is on the average more nutritive and better preserved than the others followed by the smoked and the fried. 0. niloticus, C. gariepinus and H. .forskahlii are generally liked by the respondents that r...
ABSTRACT Apparently 100 (one hundred) healthy Clarias gariepinus juveniles which measurement of mean weight and length taken respectively was used for range finding test while 75 (seventy five) was used for definitive test. They were acclimatized in de-chlorinated water (tap water exposed to air for greater than 24 hours) in lOOL capacity plastic bowl for 2 weeks. 5 fishes were kept per container. The result of this research shows the toxic nature of the quicklime on the behavioral, physico...
