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... Continue Reading

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... Continue Reading

ABSTRACT The effects of petroleum by-products (fuel and kerosene) on the hematology of African catfish (Clarias gariepinus) was studied. Ten juvenile fishes were introduced in each aquarium, and  held for 24hours in the laboratory, inside these aquaria, filled with 10 litres of unchlorinated well water. After 24hours, fuel and  kerosene (500ml... Continue Reading

ABSTRACTS A ten weeks feeding trial was carried out in order to examine the effect of including different types of lipids in the diets fed to African catfish fingerlings (Clarias gariepinus) on their growth performance and serum biochemistry. A total of one hundred (100) African catfish fingerlings with weight range of 129-130g per one 50litres... Continue Reading

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... Continue Reading

ABSTRACT This study examined the total replacement of fishmeal (FM) with poultry hatchery waste meal (PHWM) in practical diets for African catfish (Clarias gariepinus). Five iso-nitrogenous diets containing levels Diet1, 0% (control); Diet 2, 25%; Diet 3, 50%; Diet 4, 75% and Diet 5, 100% of PHWM as a replacement for FM were fed to three replicate...

GROWTH PERFORMANCE OF Clarias gariepinus FED WITH COPPENS AT A FREQUENCY OF ONCE AND TWICE DAILY CHAPTER ONE 1.0      INTRODUCTION Aquaculture, the farming of aquatic organisms including fish, mulluscs, crustacean and aquatic plant is necessary to meet the protein need of Nigerians. Overtime, there has been increase in fish production in... Continue Reading

ABSTRACT Solar energy being transmitted from the sun through space to earth by electromagnetic radiation must be converted to heat before it can be used in a practical heating or cooling system. Solar energy collectors, the devices used to convert the suns radiation to heat, usually consist of a surface that efficiently absorbs radiation and... Continue Reading

ABSTRACT Studies were carried out to determine the haematological characteristics of Clarias gariepinus healthy specimens were obtained from Gubi dam. Blood sample ranging between 1.0-1.5ml were taken with the aid of sterilized syringe (21G) inserted by caudal vein puncture. The haematological parameters for each blood specimen were measured using... Continue Reading

ABSTRACT High cost of feed is a major constraint to fish farming in Nigeria. This study investigated the growth performance of African catfish (Clarias gariepinus) fed graded levels of plantain peels (PPM). PPM was used to replace maize at 0% (T1), 25%(T2), 50% (T3), 75% (T4) and 100% (T5) for 56 days level. Data collected were analyzed One-way... Continue Reading
