The aim of this study was to provide the first data on diversity and structure of macroinvertebrates in this estuarine area. Physicochemical parameters were measured monthly in three sampling stations S1, S2 and S3, and the benthic Macroinvertebrates was collected using a Van Veen grab. A total of 28 taxa distributed among 20 families and 11 orders belonging to Annelida, Mollusca, Crustacean and Insecta were collected. The taxonomic richness and diversity were higher in S1 compared to S2 and S3, probably due to its proximity to Bandama estuary. The relative abundance revealed that mollusks represented mainly by Pachymelania aurita (16.04%), P. fusca (15.83%), Anodonta anatina (13.02%) dominated the species assemblage; followed by crustaceans with Macrobrachium vollenhovenii (31.87%) and Potamon sp. (5.01%). Canonical correspondence analysis revealed that the main factors that influenced macroinvertebrates distribution in Azagny Channel were conductivity, salinity and Total Dissolved Solids (TDS). There is a strong correlation between these three abiotic factors and their influence on species assemblage would be linked to proximity of study area to Atlantic Ocean. These findings provide valuable information that can be used to establish biotic indices to monitor the water quality of Azagny Channel.","PeriodicalId":355136,"journal":{"name":"Asian Journal of Research in Zoology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128469872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three groups are observed to have impacted the environment – Oil/gas industries, tyre burning from abattoir, untreated human and animal waste from settlers and the abattoir. The study was carried out from September 2019 to August 2020. The mean concentrations of the parameters studied in some samples were close to or exceeded World Health Organization (WHO) and Federal Ministry of Environment (FMEnv) recommended limits for drinking water and seafood. The results from this study have provided information on the heavy metals profile on the fish of the river. The level of heavy metals in the muscle of Catfish and Tilapia showed a range of Cadmium in Catfish (1-3.9mg/kg and Tilapia (0.1-4.2mg/kg) with the highest level occurring in station 2 (3.47mg/kg for Catfish and 3.39mg/kg for Tilapia) which is high with regard to FAO 19835, FAO/WHO 10896, EEC 20054 permissible limit of 0.01mg/l and USEPA SQG (1mg/kg) level in seafood. The levels of essential heavy metals in fish muscle were Copper (Catfish-10.9-33mg/kg, Tilapia -17.3-40.6mg/kg), Iron (Catfish-1.0-2.5mg/kg, Tilapia -0.1-5.6mg/kg) were within the FAO 1983 permissible limit while Zinc (Catfish-22-213.2mg/kg) and Tilapia (30.1-196mg/kg) exceeds the limit in some stations. Catfish muscles recorded higher mean value (127.12mg/kg) for all heavy metals than tilapia (44.03mg/kg) and the sequence is Copper > Zinc > Iron > Cadmium. The concentration of heavy metals in Orashi River is in the sequence: Sediment > Catfish > Tilapia >Water.

Each arm of the olfactometer served as treatment arm with the 3 arms accommodating the 3 test substances, respectively and the 4th arm as control. Various concentrations (1, 2 and 3% V/V) of the essential oils were evaluated for fumigant and contact toxicity against T. castaneum at 8, 16 and 24 hours durations. The results obtained showed that T. castaneum spent significantly (p<0.05) more time (min) in the control arm than the 3 arms accommodating the essential oils. Similarly, significantly (p<0.05) more number of entries were made by the insect into the control arm compared with the test arms. The application of the essential oils significantly (p<0.05) caused higher mortality at 8, 16 and 24hrs than the control for both fumigant and contact tests. The mortality of the T. castaneum increased with increase in the concentration of the essential oils. The 3% concentrations of the oil extracts significantly caused the highest mortality, 67.23±8.72, 69.22± 18.74 and 79.55±9.29% by A. indica, D. tripetala and J. curcas, respectively after 24 hours application in fumigant test.

The specific objectives were to determine the growth performance of rabbits fed on rabbit feed and combination of agricultural by-product with forages and compare their feed utilization. It investigated the growth performances of rabbits; (Orynctolagus cuniculus) fed diverse ration (types A and B) in captivity for 12 weeks. A total of eighteen (18) weaner rabbits with an average initial weight of 350g – 370g and between 5 and 6 weeks old, were allotted into two treatments. Each treatment had three rabbits and three replicate in a completely randomized design. Rabbits in treatment one (A) were fed rabbit feed while the treatment two (B) were fed forage and diverse foodstuffs. Proximate analysis of these food ration types A and B showed that the ration type B was high in crude protein (23.88%), carbohydrate (53.29%) and fat (8.60%) and ration type A had the lowest crude protein (20.76%), carbohydrate, (52.49%) and fat (3.15%). Studies on the indices of ration utilization and growth performances showed that feed intake was highest in rabbit fed ration type A (94.28g) and lowest in ration B (90.98g). The diverse ration types although portrayed good weight gain, the highest was in rabbit fed ration type B (760.00g) and lowest in ration A (681.00g) and ration type B was significantly (p<0.05) different from ration A. The percentage weight gain and specific growth rate were highest in ration type B (210.50%), (4.097) and lowest in ration A (189.10%), (3.841).

The species itself is representative of the habitat of the Danube Delta, where it was also immortalized, and where the inspiration for the layout of the philatelic pieces came from. Moreover, through the rich philatelic material identified, analyzed, and presented, one can discuss the other philatelic effects. All these, through the beauty of the exhibition and the contribution brought among the collectors, philatelists, and implicitly of those who love nature, make the issue a successful one.

We do not know the origin of this muscular pathology and the purpose of this work is to summarize some of the findings with optical microscopy and electron microscopy shared by all. Although we cannot establish the etiology of this atrophy, we will try to correlate the ultrastructural alterations with the muscular histopathology. Muscular atrophy is a pathology characterized by loss of normal muscle mass. It is caused by a decrease in the total number of muscle cells or by a substantial reduction in the substance of individual muscle cells. It is likely that the cases reported here represent a pathology involving causes concurrent with nutritional problems and disorders of muscle innervation. Therefore, future studies should investigate further about the potential of neurodegenerative disorders. Several experimental models can use muscular atrophy and are suitable for investigations of the underlying mechanisms of this pathology.","PeriodicalId":355136,"journal":{"name":"Asian Journal of Research in Zoology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116904230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
