Abstract The study evaluated the genetic signatures of fishes from two populations and compared pattern differentiation with a view to separating species different into possible sub-species. Forty (40) specimens were collected River Niger (Lokoja) Asejire Resevoir. DNA twenty (20) each population extracted muscle tissue using phenol-chloroform extraction (PCE) method was subjected microsatellite analysis. Seven (7) markers (Cga01, Cga02, Cga03, Cga05, Cga06, Cga09 Cga10) used in...

Abstract Inland fisheries are an important source of protein and income for people in Africa. Their sustainable management can greatly benefit from identification regional genetic stocks characterization their diversity, but such information is lacking most African freshwater fisheries. The bonytongue, Heterotis niloticus , component inland West Nigeria has the largest fishery bonytongues, representing ~ 86% global total. Recent declines yields at some Nigerian locations, however, suggest...

Inland capture fisheries play a critical role in supporting food security and livelihoods Africa. Therefore, it is important to evaluate the genetic health of exploited fish populations. The African bonytongue, Heterotis niloticus, supports commercial subsistence western However, sharp declines stocks have been reported. Herein, we estimate contemporary effective population sizes (Ne) four populations Nigeria, three Benin, five Cameroon using Linkage Disequilibrium methods. Ne estimates were...

The genetic polymorphisms of catfish populations collected from four fish farms in Southwestern states Nigeria were determined by Randomly Amplified Polymorphic DNA Polymerase Chain Reaction technique. This was to characterize the strains genetically and provide information on studied catfish. Following standard procedures, polymerase chain reaction performed mixing 15 μl mixture containing FIREPOL® Taq polymerase, MgCl2, dNTPs, distilled water, dyes glycerol, with 1.0 sample 16-week old C....

The African bonytongue, Heterotis niloticus, supports commercial subsistence Sharp declines stocks have been reported, however. Herein, we estimate contemporary effective population sizes (Ne) four populations Nigeria, three Benin, five Cameroon using the Linkage Disequilibrium method with correction for...

The food and feeding habits of the redbelly Tilapia (Tilapia zillii) Guenther’s mouthbrooder (Chromidotilapia guntheri) were investigated in an abandoned gold mine reservoir at Igun from June 2013 to May 2014. Using a cast net gill-net fishing gears, 370 fish individuals caught their stomach contents analysed by using frequency occurrence numerical methods. zillii comprised 53.78% (199 individuals), while Chromidotilapia guntheri covered up remaining percentage (46.22%) which is made 171...

Genetic diversity of four populations honey bee, Apis mellifera from two vegetation zones in Nigeria namely; southwest rainforest and northcentral derived savanna was analysed using fifteen morphometric characters five microsatellite loci. Discriminant function analysis (DFA) the data revealed a considerable variation morphological between sampled localities while Principal Component Analysis (PCA) Canonical Variate (CVA) produced overlapping clusters indicating lack separation various...

Abstract Thirty Lates niloticus (Linnaeus, 1758) from three Nigerian waterbodies were genotyped on six RAPD primers and five microsatellites loci. revealed that effective number of alleles (A E ) at population level per locus was within the range 1.641 ± 0.066 to 1.645 0.041 while mean N across populations equals 2.000.

Abstract Inland fisheries are an important source of protein and income for people in Africa, sustainable management requires knowledge regional stocks. Presently, information regarding genetic diversity African freshwater fishes is very limited. Here we present findings from a spatial analysis patterns the bonytongue, Heterotis niloticus , component inland West Africa. The species common throughout Western Central Africa Nile Basin; has been introduced aquaculture locations across Nigeria...

Identifying insecticide resistance mechanisms is paramount for pest insect control, as the understandings that underpin control strategies must provide ways of detecting and managing resistance, thus study identified ability Carboxylesterase (CarEs) genes in conferring to commonly used pesticide by examining expression gene susceptible resistant strain Zonocerus variegatus, after Cypermethrin bioassay.Adult Z. variegatus was sampled from Savannah area Oyo State, Nigeria, samples were...
