The green seaweed Ulva is one of South Africa’s most important aquaculture products, constituting an important feed source particularly for abalone (Haliotis midae L.), and utilized as a bioremediation tool and other benefits such as biomass for biofuel production and for integrated aquaculture. Besides Ulva spp, Gracilaria spp. are also cultivated...

To enhance agricultural production in developing countries, the use of information and communication technologies (ICTs) in extension delivery services is of great importance. This study examined personal characteristics of respondents, type of ICTs available, benefits of use of ICTs and constraints to use of ICTs among extension officers in Lagos...

The biological composition of fish food and water can affect the minerals and nutrient composition of the fish, showing the relationship between the fish, its habitat and what they eat.This has necessitated the research on the amino acid, mineral and proximate compositions of Heterotis niloticus and Macolorniger from coastal water bodies to investi...

The increase in integrated multitrophic aquaculture (IMTA), where seaweed (particularly Ulva rigida C. Agardh, 1823) is used as a feedstock and a wastewater scrubber in South African IMTA systems, has necessitated research into seaweed growth rates, which has subsequently increased production technologies. Seaweed growth can be increased by control...

The approximate, protein and inorganic constituents of two economically important freshwater clariids were determined and their corresponding water quality of the habitat was conducted to investigate the environmental safety and the process of obtaining nutrition necessary for health and growth gains to consumers. The 50 fish samples of Chrysichthy...

This research work was carried out to investigate the effect of drying methods on functional properties and pasting behaviour of bitter yam (Dioscorea dumetorum) flour. Flour processed from bitter yam tubers was subjected to sun drying and oven drying methods at 4% moisture contents level, under the temperature of 32.3 ± 0.2 0 C and 61.8 ± 0.2 0 C...

Nutrient constituents of Tilapia zillii and Sarotherodon galilaeus vis-à-vis proximate, mineral and amino acid contents were evaluated. A total of One hundred fish samples, comprising of 50 T. zillii and 50 S. galilaeus, with weights ranging from 500-800g procured from Agbalata market, Badagry, Lagos. The fish species were subjected to proximate, m...

Study on the effects of metals on growth rate and survival of Clarias gariepinus (Burchell 1822) fingerlings bred in tanks containing water concentrated with inorganic fertilizer and detergent was conducted. 300 fingerlings of C. gariepinus (7.5±0.24) were stocked into different tanks of 5000m 3 capacity water and fed with formulated diet for 8 wee...

The research is about the nutritional quality of few fresh water species mostly consumed in some part of Lagos Nigeria. The work x-rayed the Thiobarbituric acid, acid value, peroxide value, iodine value ,free fatty acids and saponification values of each of these identifies fish. The research ascertained the quality improvement in fish caught in ea...

In South Africa the green macroalga Ulva armoricana is the main species of macroalgae cultured. The species is currently the largest aquaculture (2884.61 tonnes) product by weight with a corresponding capacity for biogas (CH4) production. We have shown that biotransformation of U. armoricana to Liquefied Petroleum Gas (LPG) is viable and economical...

Ulva is currently South Africa’s largest aquaculture product by weight, its production having developed steadily using integrated multitrophic aquaculture (IMTA) paddle wheel ponds as the preferred method of production. Ulva spp are exciting prospects for energy efficiency as demonstrated by biotransformation to Liquefied Petroleum Gas (LPG) studie...

Soybean (Glycine max ) is one of the most important food crops and a primary source of food for reasonable percentage of the world’s population. This study investigated the effect of processing methods on the organoleptic qualities, functional characteristics and proximate values of soybeans. Flours prepared using four different processing methods...

The level of some Potential toxic metals PTM (Zn, Fe, Mn, Cu, Pb and Cd) in Synodontismembrane (Catfish), Tilapiazilli (Tilapia), Callinectesamnicola (Crab) and Macrobrachiummacrobachion (Prawn), from Lagos Island and Epe lagoon were investigated using Atomic Absorption Spectrophotometer (AAS), model Buick Scientific 210 GVP, the analysis on all th...

Under cultivation, macroalgae grow rapidly and synthesize large amounts of carbon/energy reserves while utilizing wastewater. Seaweed can remove pollutants from industrial agriculture effluent and reduce coastal eutrophication. In South Africa, Ulva armoricana’s growth rate, ease of harvesting and resistance to contamination by other algal species...

An on-land flow-through cultivation system was designed for the macroalgal species Ulva armoricana (Chlorophyta) to reduce the environmental impact of aquaculture effluent in coastal ecosystems as part of an integrated aquaculture system. The macroalgae was cultured in various enriched media at a stocking density of 500 kg wet weight/pond. Overall,...

A twelve week investigation into the effects of feeding substituted palm oil (PMO) with coconut oil (CNO) as an alternative source of energy, on the growth performance and nutrient utilization of Clarias gariepi-nus juveniles was conducted. Six (6) isonitrogenous 40% crude protein diets were formulated where CNO replaced PMO at 100%, 80%, 60%, 40%,...

It is an established fact that climate change caused by human-induced concentrations of greenhouse gases (GHG), especially CO2 emissions, are increasing in the earth’s atmosphere and is one of the greatest challenges the world is currently facing. Algae play significant roles in normal functioning of the atmospheric environment and are important ca...

Twelve (12) cultured adult Clarias gariepinus, six (6) male and six (6) female of average weight 795±179.52g were used to investigate the lipid profile and liver marker enzymes; important and efficient biochemical indices used in determining the general well-being of an organism. Concentrations of cholesterol, triglycerides and phospholipids (lipid...

A study was carried out to assess the physico-chemical, heavy-metals parameter and Histopathology of adult fish specimen of Oreochromis niloticus and Clarias gariepinus collected from effluents sources of Ologe lagoon. The aim of the study is to assess the impact of industrial effluents on the lagoon, and on the health of resident fish fauna. 5 sam...

effects of feeding varying levels of substituted pigeon pea seed meal (PSM) on the growth performance and carcass characteristics of Clarias gariepinus. Five isonitrogenous 40% crude protein diets were formulated where PSM replaced Soya Bean Meal (SBM) at 0%, 25%, 50%, 75% and 100% inclusions. Juveniles of C. gariepinus (15.74 ± 1.22g) stocked at 1...

Climates related disaster is greatly human induced warming, leading to substantial fluctuations in earth temperature which is currently a global issue of environmental concern. Human proximity and pressure in and around the coastal region has threatened flora, fauna and micro-organic resources of economic importance in most developing nations. Two-...
