TOXICITY OF CASSAVA EFFLUENT ON CATFISH (Clarisgariepinus) AND SOME TARGET ORGANS

ABSTRACTA 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 efflu...

Evaluation of Microbal Loads of Wild Caught Fresh and Processed Fish Species From Ekiti Environs. The Public Health Implications

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...

DIETARY EFFECT OF GINGER (Zingiber officinale) ON GROWTH AND HAEMATOLOGICAL PERFORMANCE OF AFRICAN CATFISH (Clarias gariepinus)

ABSTRACTThe 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 o...

EFFECT OF BATTERY WASTES ON AFRICAN CATFISH Clarias gariepinus FINGERLING

 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...

EFFECTS OF OLEANDER SEED MEAL BASED DIET ON GRO,WTH PERFORMANCE, HAEMATOLOGY AND TISSUE COMPOSITION OF Clarias gariepinus FINGERLINGS

 ABSTRACTAn 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% ...

EFFECT OF AUTOCLAVED CASTOR SEED MEAL ON GROWTH PERFORMANCE, BODY COMPOSITION AND HAEMATOLOGY OF Clarias gariepinus FINGELINGS

ABSTRACTEight 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%, a...

EFFECTS OF PROPHYLATICS ON GROWTH PERFORMANCE AND PHYSIOLOGY OF AFRICAN CATFISH Clarias gariepinus (BURCHELL, 1822) FINGERLINGS

 ABSTRACTThree 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 triplicate...

MORPHOMETRIC CHARACTERISTICS OF Hydrocynus forskahlii (Cuvier 1819) FROM UREJE DAM, ADO EKITI

 ABSTRACTFor 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 an...

NUTRITIVE AND ORGANOLEPTIC ASSESSMENT OF THREE FISH SPECIES PROCESSED BY DRYING, SMOKING AND FRYING) FROM AILARA FISHING COMMUNITY, ASA RESERVOIR, KWARA STATE

 ABSTRACTThis 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 tha...

 ABSTRACTApparently 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, phys...

Fish of an average initial weight of 5.18g were stocked in 15 plastic aquaria of about 25litres capacity each at a rate of 15 fish per aquarium Fish meal protein (18% of the diet) was used as the sole source of animal protein in the control diet. Per...

LATERALIZATION AND AGGRESSION IN NILE TILAPIA (Oreochromis niloticus)

 ABSTRACTLateralization (eye preference) or handedness has been studied over the years in different species of vertebrates in 9ther to study how they perform multiple tasks simultaneously with respect to their survival, tenacity, responses, detection, etc. Mirror and dyadic test were used to test, determine, and compare the aggression and lateralization levels of Nile tilapia (Oreochromis niloticus) with its own mirror image, an opponent and potential natural predator. 120...
