Solid Waste Management of Fishery and Shrimp

Abstract: Solid waste management is one of the important areas focused by several researchers as it reduces environmental degradation, and offers useful or value added products. Fishery waste is significantly available in coastal areas and food processing industries which are a threat to the environment. Reuse or recycling is a better option to reduce the disposal of fishery waste. In this study, two different fishery wastes were investigated for their use for waste water treatment application. Chitosan was prepared from fishery and shrimp wastes by alkaline N-deacetylation process. Further Chitosan was characterised by the Fourier transform infra red analyser (FTIR), X-ray diffraction (XRD) and Viscosity-molecular weight. The FTIR results showed a more detailed structure of α-chitin in the region of O-H, N-H and CO stretching region. The FTIR spectrum was used to determine the chitosan degree of acetylation (DA).

Insights into small scale commercial water services in Nigerian urban area

Abstract: This paper reviewed the operation of the Small Scale Commercial Water Providers (SSCWP) in Yola, the capital of Adamawa state, North Central Nigeria. It provide an insight into their contributions, pattern of expenditure on commercial water supply, their operational constraints and possible solutions; and implications of all these issues for sustainable urban development. The methodology employed a household survey and a survey covering the operations of the SSCWP as well as government officials. Results obtained show that 65% of households in Yola presently rely on SSCWP as a coping strategy. The study recommends regulatory oversight to be created through legislation geared towards a water policy that will improve access to portable water base on an all-inclusive approach. This will lead to improvement in public health.

Repellency Effects of Three Indigenous Plant Extracts Against the Red Rust Flour Beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) in Northeastern Nigeria

Abstract: Background: The current study was conducted in the Laboratory of Department of Crop Protection, Modibbo Adama University of Technology, Yola to evaluate the repellent effects of different concentrations of extracts of Azadirachta indica (Neem, Moringa oleifera (Drum stick) and Hyptis souveolens (Pig weed) against Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) at various time intervals and their interactions. Three concentrations viz; 5, 10 and 15% were applied to evaluate the Repellence of T. castaneum at five different exposure periods of 24, 48, 72, 96 and 120 hours. Repellence action of extracts of A. indica, H. souveolens and M. oleifera evaluated against the T. castaneum had maximum repellency (81.63%) at highest concentration of 15%, followed by H. souveolens (79.37%) and M. oleifera (50.46%). Regarding interaction between concentration and time, repellence increases with respect to increase in concentration, but reduces with passage of time. This shows that toxicity effects of these plant extracts is directly affected by concentration and time. Therefore, this study confirmed that these plant extracts are effective in the Original Research Article Medugu; APRJ, 7(4): 46-52, 2021; Article no.APRJ.69226 47 management of T. castaneum and most effectively at higher concentration within short period of time.

Phylogeography and Antioxidant Activity of Proso Millet (Panicum miliaceum L.).

Abstract: Proso millet (Panicum miliaceum L.) or broomcorn millet is among the most important food crops to be domesticated by humans; it is widely distributed in America, Europe, and Asia. In this study, we genotyped 578 accessions of P. miliaceum using 37 single-sequence repeat (SSR) markers, to study the genetic diversity and population structure of each accession. We also investigated total phenolic content (TPC) and superoxide dismutase (SOD) activity and performed association analysis using SSR markers. The results showed that genetic diversity and genetic distance were related to geographic location and the fixation index (Fst). Population structure analysis divided the population into three subpopulations. Based on 3 subpopulations, the population is divided into six clusters in consideration of geographical distribution characteristics and agronomic traits. Based on the genetic diversity, population structure, pairwise Fst, and gene flow analyses, we described the topological structure of the six proso millet subpopulations, and the geographic distribution and migration of each cluster. Comparison of the published cluster (cluster 1) with unique germplasms in Japan and South Korea suggested Turkey as a possible secondary center of origin and domestication (cluster 3) for the cluster. We also discovered a cluster domesticated in Nepal (cluster 6) that is adapted to high-latitude and high-altitude cultivation conditions. Differences in phenotypic characteristics, such as TPC, were observed between the clusters. The association analysis showed that TPC was associated with SSR-31, which explained 7.1% of the total variance, respectively. The development of markers associated with TPC and SOD will provide breeders with new tools to improve the quality of proso millet through marker-assisted selection.
