Abstract A twelve-week feeding trial was carried out to assess the nutritive potentials of kola pod husk and to assess the growth performance of Clarias gariepinus juveniles on varying levels of kola pod husk- supplementation. The objective of this study was to assess the nutritive potentials of kola pod husk on the penance of C. gariepinus and its level of incorporation in such diets. Eight acpaimental bowls (6Ox30x30cm~ were used for the experiment There were four treatments with each treat...
ABSTRACT Efforts to integrate rural people into biodiversity conservation through community-based conservation programs is an old tradition. These efforts were largely based on economic incentives, with little or no attention given to the role of culture and traditions in building support for conservation. Although these strategies are useful in promoting conservation and local empowerment, they are still fragile. Scholars suggest that incorporation of traditional values which reflect locall...
Lethal and sub-lethal effects of copper on Clarias gariepinus were studied using a 96-hour static bioassay. Copper (as copper chloride, CuCl2 . H2O) was used to prepare the stock solution from which five standard concentrations 0.0, 1.8, 3.2, 5.6, and 10.0 mg/L were prepared (coded A – E). 15 juvenile C. gariepinus fish having a mean weight and length 5.8g and 18 cm respectively were used. The 96-hour LC50 estimated using the logarithm method were 0.6, 0.71 and 0.7 mg/l for replicates...
ABSTRACT Most of the serious problems facing protected areas in Africa today have a human component. Among the more common problems are human encroachment, unauthorized harvesting of resources, and the conflict between wildlife managers and local people. The study illustrates the major wild Animals, agricultural and livestock pest in the study area and the attitudes of the farmers/villagers to wild animal species. A land-use planning system that incorporate a floating zoning system which ulti...
ABSTRACT A study was undertaken to determine the plankton and benthos of Ekole River in Bayelsa State of Nigeria. Surface water and sediment samples were collected in the dry (December-January) and wet (June –July) seasons between 2003 and 2004 for plankton and benthic analyses. The water temperature ranged from 27-33°C, pH 6.30-7.5, total suspended solids (T.S.S) 110-282 mg/L, Chloride 15.40- 39.6 mg/l, dissolved oxygen 4.11-10.83 mg/l and conductivity 64.5-84.55µS/cm. The total plankton...
ABSTRACT The nutritional potential of sun-dried cow blood meal (CBM) was investigated for its effect on growth performance, haematology and plasma enzyme activities in hybrid catfish fingerlings (Clarias gariepinus Male x Heterobranchus longifilis Female), in an assay that lasted for twelve weeks.
ABSTRACT Fertilizer application in earthen ponds has been used as a low cost method of sustainable aquaculture production.
ABSTRACT The study evaluated the potential of sweet potato meal as a replacement for maize at a varying inclusion levels in the diet of advanced fry of Clarias gariepinus.
The nursery management of Clarias gariepinus is expensive and usually accompained by high mortality.
ABSTRACT Oil spillage is of critical concern in Nigeria because of the problems of pollution and associated disturbances. it is therefore necessary to study the effects of oil pollution on fish using clarias gariepinus, a widely cultured fish species in the tropics.
ABSTRACT A 6 week feeding trail was conducted in glass tanks with juveniles Clarius glariepinus to examine the effects of partial and total replacement of fishmeal with sesame seed cake protein.
ABSTRACT An experiment was undertaken to determine the effect of boiling of cocoa pod husk and levels of inclusion that will positively affect the growth rate of CIarias gariepinus, a major species of importance cultured in Nigeria Cocoa Pod husk is a by-product of cocoa industry often discarded as Waste. This study was to assess the effect of incorporation of boiled Cocoa pod husk into the diets of C.gariepinus juveniles.
ABSTRACT A study was carried out to determine the physico-chemical characteristics of the water of the Cross River and coastal areas of Cross River and Akwa Ibom States of Nigeria.
ABSTRACT This experiment was conducted to evaluate the effects of walnut (T. conophorum) leaf and onion (A. cepa) bulb on the gut morphometry of Clarias gariepinus towards elucidating its mechanism of growth promotion. Twenty Clarias gariepinus juveniles (7.39±0.29g/ fish) were allocated to nine treatments, with three replicates each. Nine experimental diets were formulated at 40% crude protein representing different level of walnut leaf and onion bulb (0.5%, 1.0%, 1.5% and 2.0%) respectivel...
ABSTRACT Toxicity testing of chemicals on animals has been used for a long time to detect the potential hazards posed by chemicals to man. Bioassay technique has been the cornerstone of programmes on environmental health and chemical safety (Ward and Parrish, 1982). Lead is a potentially toxic chemical that may be directly ingested by man or indirectly through aquatic animals like fish and shellfish .The effects of lead on man include mental retardation, learning dysfuntion, and loss of coord...
