Abstract P. biglobosa, known as néré or the shea butter tree, is an important multipurpose tree in tropical and subtropical Africa, particularly valued for food uses. It occurs naturally in Africa between 15°N and 0°N in a strip extending from the Atlantic to the Indian Ocean across Mali and Chad, to Cameroon, Sudan and Uganda, as well as in the Central African Republic. The natural phytogeographical distribution of Parkia biglobosa corresponds to the "Sudanian Regional Centre of Endemism" and the "Guineo-Congolia/Sudania Regional Transition Zone" (White, 1983). The species is often found with Vitellaria paradoxa in cultivated parklands near villages with short fallows. In most cases, P. biglobosa has been conserved from land clearing, it is rarely planted. In savanna woodland, P. biglobosa occurs with Pterocarpus erinaceus, Khaya senegalensis, Daniellia oliveri, Afzelia africana, Prosopis africana etc.

The study evaluated nutritional and organoleptic properties of Clarias gariepinus pre-treated with aqueous leave extracts of Ocimum gratissimum and Vernonia amygdalina before processing. Thirty-six (36) C. gariepinus (live weight = 1.2± 0.2kg) samples were procured and processed for the study. Fish samples were divided into three parts of twelve fish each. Each part was grouped into three treatments having four fish in each group using a completely randomized design. Treatment one (T1) had fish immersed in 5% brine without herbal extract (control). In Treatment two (T2), fish were soaked in mixture of 5% brine and 5% O. gratissium (scent leaf) extracts while Treatment three (T3) had fish soaked in mixture of 5% brine and 5% V. amygdalina (bitter leaf) extracts all for 30 minutes. Treated fish samples were smoke-dried using charcoal kiln for 5 hours at temperature of 80 – 90° C. Samples were then cooled under ambient condition (30+3oC) for 4 hours. The smoke-dried fish samples were labeled according to treatments and stored for 7 days under aseptic condition. Organoleptic properties of the samples were conducted at every 24-hour of storage using a 9-point hedonic scale. Mean values of proximate composition of samples were significantly different (p<0.05). Protein content (70.01%) in T3 was higher than 68.31% and 66.62% in T2 and T1 respectively. Similarly, fat (5.12%) and ash (4.68%) levels for T3 were higher than 4.85% and 4.46% fat with 4.36% and 3.98% ash contents for T2 and T1 respectively. Results of mean scores for each organoleptic property decreased significantly (p<0.05) during storage period with no consistent trend in score pattern.

L’objectif  de  cette  étude  est  d’évaluer au Bénin l’efficacité du réseau des aires protégées dans la conservation des habi- tats favorables et prioritaires de certaines espèces ligneuses d’importance socio-éco- nomique. Il s’agit de Afzelia africana, Anogeissus leiocarpa, Burkea africana, Daniellia oliveri, Detarium microcarpum, Prosopis africana et Khaya senegalensis. Les techniques basées sur le principe d’en- tropie maximale (Maxent) combinées avec les SIG ont été utilisées pour projeter les habitats favorables de ces sept espèces ; le logiciel Zonation a été utilisé pour la modé- lisation des habitats prioritaires. Les points de présence des espèces ont été collectés et associés aux variables bioclimatiques dérivées de la température mensuelle et de la pluviométrie obtenues à partir de la base de données en ligne de AfriClim, ainsi qu’à la variable édaphique (sol). En terme de déterminisme environnemental, les variables bioclimatiques telles que l’écart diurne moyen de la température  (Bio2), les précipitations annuelles moyennes (Bio12), l’évapotranspiration potentielle (ETP) et la variable biophysique sol, sont prédictives pour les distributions des sept espèces. Les habitats protégés plus favo- rables aux sept essences dans la zone gui- néenne commencent aux limites de la forêt classée de Kétou (7°43’N), dans la zone soudano-guinéenne, à partir de la lati- tude de la forêt classée d’Agoua (8°30’N), et dans la zone  soudanienne  à partir  de la latitude de la Pendjari (10°35’N).  Pour  la conservation des habitats prioritaires, l’étude de représentation révèle que, dans les zones soudaniennes (9°75’-12°27’N), guinéenne (6°50’-7°40’N) et soudano-gui- néenne, les aires protégées sont respec- tivement efficaces, peu efficaces et non efficaces.

Aeromonas spp, ubiquitous in both terrestrial and aquatic environments are becoming renowned as enteric pathogens of serious public health concern as they have a number of virulence and resistant determinants that are linked to both human and aquatic diseases due to consistent and incorrect use of antibiotics in aquaculture. The effect of crude aqueous and ethanol extracts of some medicinal plants on antimicrobial resistant Aeromonas spp. isolated from aquaculture water and fish samples was studied. Two hundred and forty (240) Aeromonas isolates, made up of 168 Aeromonas hydrophila and 72 Aeromonas salmonicida, were recovered from aquaculture water and fish gill samples collected from different commercial fish ponds using selective media. The isolates were assessed for their antibiotic susceptibility against ten (10) conventional antibiotics using the Kirby-Bauer technique. Extracts from three medicinal plants, Vernonia amygdalina, Ocimum gratissimum and Garcinia kola were also analyzed for their antimicrobial effects on the isolates that were resistant to the conventional antibiotics. Aeromonas hydrophila isolates expressed the highest resistant rates of 100%, 78.6% and 70.8% to aztreonam, cefotaxime and neomysin respectively, and the A. salmonicida isolates also had a similar trend of high resistant rates of 100%, 87.5% and 77.8% to aztreonam, neomysin and cefotaxime respectively. Antimicrobial resistant analyses with the plant extracts showed 100% inhibition of the isolates at 100 mg/ml for both aqueous and ethanol extracts. Phytochemical screening identified the presence of certain phytochemicals like alkaloids, saponins, tannins, flavonoids, steroids and glycosides which could have accounted for the antimicrobial effects of the plant extracts under study. It can be inferred then, that extracts from Vernonia amygdalina, Ocimum gratissimum and Garcinia kola can inhibit resistant aquaculture Aeromonas isolates and so can present an alternative source of antimicrobials in the effort to combat the increasing incidence of antimicrobial resistance in aquaculture.
