The FAME were determined by GC-MS and were identified using retention time locked methods and retention time databases. The fatty acids profiles include minor amounts of odd-number, branched-chain, and even-number fatty acids as well as saturated components, the MUFA and PUFA. The major SFA were C14:0 and C16:0. The C18:1 was the prominent MUFA. The dominant PUFA are of the omega-6 series and are found chiefly in C18:2 fatty acids. The essential fatty acids compositions showed prominence in C18:3n-3 and C18:2n-6. The branched chain fatty acids identified C15:0, C16:0, C17:0, C18:2 and C20:0. The overall significance of this study is the revelation that freshwater fishes have irregular pattern of FA which are good sources of omega-6 EFA. The high percent of branched and saturated FA in freshwater fish gives them an advantage in curing processing. http://dx.doi.org/10.1038/npre.2009.3239.1 Wed, 13 May 2009 15:11:38 UTC Fatty acids composition of some freshwater fish doi:10.1038/npre.2009.3239.1 2009-05-13 Chukwuemeka Ugoala Nature Precedings 2009-05-13T15:11:38Z Manuscript Biotechnology Chemistry http://creativecommons.org/licenses/by/3.0/ http://dx.doi.org/10.1038/npre.2009.3018.1 Drying sessions were conducted across Nigeria to study the interaction between fish weight loss and the meteorological parameters. Correlation analyses using weight loss values show that latitude is strongly related (r =+0.96) to weight loss of fish inside the dryer while altitude had a weak relationship (r = +0.24) with weight loss. The results show that New Bussa recorded more weight loss of fish than Jos, despite their uniform latitude. Weight loss records in Jos, was however better than those of Warri and Ibadan. http://dx.doi.org/10.1038/npre.2009.3018.1 Thu, 02 Apr 2009 13:17:00 UTC Study of Fish Weight Loss in Solar Dryer Across Different Agro-Ecological Zones of Nigeria doi:10.1038/npre.2009.3018.1 2009-04-02 Emeka Ugoala Nature Precedings 2009-04-02T13:17:00Z Manuscript Biotechnology Ecology Earth & Environment http://creativecommons.org/licenses/by/3.0/
