Abstract. The history of Biology at its earliest periods cannot be described without mentioning the roles played by Aristotle, Hippocrates, Galen and, Theophrastus in ancient Greco-Roman world, and Leonardo DaVinci in Italy among others,who did studies that helped ignite and consequently shape the early periods of the study of Biology as a field of...

A survey of some refuse dumpsites in Ifite, Awka, Anambra, Nigeria State were carried out for 5 weeks to determine the arthropod vectors associated with those refuse dumps and their relative abundance per site and species diversity. Five refuse dumpsites were randomly selected based on their composition and human activities within the environment....

The present study investigated the perception of fish farmers to agricultural extension services in Anambra State. Specifically, the study investigated the socioeconomic characteristics, extension service sources and information given. A structured questionnaire was administered to the fish farmers to collect information. A total of 96 fish farmers...

An evaluation of concrete structure on the fish fauna in Ogbei Stream, Southeastern Nigeria was studied. Fish samples were collected from six stations namely stations 1, 2, 3, 4, 5 and 6 for twelve months between May 2008 and April 2009. A combined total of 694 species of fish belonging to 6 orders, 10 families and 15 species were recorded in the s...

The present study reports the bioaccumulation of cadmium (Cd), zinc (Zn), lead (Pb) and mercury (Hg) in the gills, muscles and intestine of Tilapia zillii, Malapterurus electricus and Clarias gariepinus sampled from fishermen at Niger River, Onitsha shelf. Heavy metals in gills, muscles and intestine of fishes was investigated using Varian AA240 At...

Recently, considerable attention has been focused on dietary supplements that possess hypoglycaemic and hypolipidemic properties in lieu of the synergistically synthesized drugs like statins and metiform which have been proven to have adverse effects. This present work was carried out to study the potential effects of Lipton tea aqueous extract (LT...

Fish constitute more than half of the total number of all the aquatic vertebrates in the world; thus, a study was carried out for six months from January-June, 2016 to investigate the physico-chemical parameters, composition, abundance and diversity of ichthyofauna present in some sections of Omambala, Ezu and Ahommiri Rivers in Anambra state, Nige...

The increasing discovery of more medicinal plants have triggered increased scientific screening of their bioactivity in order to provide data that will help physicians and patients make wise decision before using them. This study was designed to elucidate comparative phytochemical and antioxidant properties of crude seed powder, aqueous and methano...

The influence of abattoir wastes on macroinvertebrates distribution in River Idemili, SouthEastern Nigeria, was studied. Three sampling stations 1, 2 and 3 representing upstream of the impacted site, impacted site and downstream of the impacted site respectively were selected. The water quality characteristics, which were significantly different (p...

The efficacy of replacing fishmeal with African yam bean (AYB) (Sphenostylis stenocarpa) meal in the feed of African catfish hybrid (Clarias gariepinus ♂ x Heterobranchus bidorsalis♀) on growth and gonad development was evaluated for a period of 10 weeks. The experimental diets contained African yam bean meal at levels of 0% (Diet 0), 25% (Diet 1),...

A comparative study of feeding frequency on growth and feed utilization of Clarias gariepinus fed on commercial feed was carried out in Awka. Ninety (90) fingerlings of mean weight 8±0.4g and length 4.7 ±1.1cm were used. Ten (10) fingerlings were stocked per 70 liter capacity receptacles in triplicates in a completely randomized design. They were d...

Most efforts towards boosting reproduction in snails are directed towards nutrition and soil composition and little emphasis have been placed in exploring other factors that might influence reproduction in snails. The influence of housing types on reproductive characteristics of Achatina achatina was investigated with ninety juvenile snails subject...

Seasonal changes in physico-chemical parameters of Wusum reservoir was investigated for twelve months in three selected stations. Water samples were taken from the surface of the reservoir and transported to the laboratory for analysis. Temperature was determined in-situ. Hydrogen ion concentration, conductivity, turbidity, nitrate-nitrogen and pho...
