ABSTRACT High cost of conventional feedstuffs and competition between livestock and fish for ingredients necessitate research into low cost, non-conventional feedstuffs for profitable fish farming. In aquaculture, the emphasis is on producing feeds that promote growth and health of fish. There is scanty documentation of the potential of onion (Allium cepa) bulbs and walnut (Tetracarpidium conophorum) leaves in fish production. The growth performance of Clarias gariepinus on diets containing ...
ABSTRACT The study investigated whether progeny of Sarotherodon melanotheron from two different populations would have higher reproductive capacity and also exhibit desirable aquaculture traits. Broodstock of S. melanotheron were collected from Kakum Estuary and Benya lagoon and bred to the second filial generation stage. Reproduction was higher in the parents from the Estuary than those from the lagoon. Water quality parameters were within the acceptable range for fish culture. Three diffe...
ABSTRACT Aspects of the ecology and spatial context of Etse Lagoon at Abandze, in the Central Region of Ghana were studied from April 2014 and March 2015. Water temperature ranged from 24.0 ⁰C to 36.6 ⁰C (mean = 29.43 ± 0.12 ⁰C). Salinity varied from 0.72 ‰ to 22.30 ‰ (mean = 13.42 ± 0.30 ‰), pH from 4.6 to 8.9 with a mean value of 7.6 ± 0.03, DO from 1.65 mg/l to 11.15 mg/l with a mean value of 5.08 ± 0.08 mg/l and conductivity from 7.35 mS/cm to 43.3 mS/cm with a mean value...
ABSTRACT The current study evaluated growth performance, survival rate, feed conversion ratio, heterosis, heritability, responses to selection and breeding values of four populations of Sarotherodon melanotheron from Fosu Lagoon, Brimsu, Baifikrom and Weija reservoirs in 4 × 4 diallel crosses aimed at producing a hybrid with high growth, reproductive and survival traits to enhance aquaculture production. Triplicates of a single-pair mating design for the diallel crosses yielded 3,840 fingerl...
Aquaculture has a great potential for growth in Kenya. There has been need for the government to promote fish culture to attain sustainable development goals of zero hunger. The study aims at investigating factors influencing sustainable development of fresh water Aquaculture in Kenya A case of Vihiga County. The objectives of the study are investigate how Production factors, and Extension influence sustainable development of freshwater aquaculture .Descriptive research design was used. The ...
Globally, Fish feeds account for 40% to 60% of the operating costs in any aquaculture production system. There has been need for the government to promote fish culture to attain sustainable development goals of zero hunger. The study aims at analyzing the cost effectiveness of on farm formulated fish feeds in relation to commercial fish feed for sustainable aquaculture production in Kenya a case of Vihiga County. The objectives of the study are: To examine the profitability level of using on-...
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. ...
