A total of thirty - one (31) species representing seventeen (17) families were identified under the families Bothidae, Charangidae, Clupeidae, Cynoglossidae, Drepanidae, Eleotridae, Gobiidae, Haemulidae, Polynemidae, Soleidae, Sciaenidae, Sparidae, Sphyraenidae, Scombridae, Tetraodontidae, Trachinidae and Trichuridae. Monthly abundance was lowest in April (122 specimens; 6.21 %) and was highest in March (545 specimens; 27.72 %). The longest species was Trichirus lepturus while the shortest were Drepane africana and Selena dorsalis. Family Sciaenidae had the highest representation in terms of species and Haemulidae had the highest number of individuals. Shannon-Weiner Index of general Diversity (H) value was showing dominance of in Charangidae family. Evenness Index (E) showed all the species were not equally distributed in the waters. Assessment of the condition factor (K) revealed that 22 out of 31 fish species K values less than 5 showing good body condition and wellbeing of the fish while 11 species showed bad body condition. The estuary has a rich ichthyofauna complex. Effective exploitation measures should be used to deter the menace of local extinction in the near future.","PeriodicalId":495334,"journal":{"name":"Asian Journal of Research in Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807740","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}

Two hundred chickens, aged 6 weeks, were utilized in the study and randomly assigned to four groups of ten birds each, housed on peanut shell bedding. The diets were formulated using a variety of local ingredients including millet, wheat bran, millet bran, peanut cake, sorrel seeds, fish meal, locust meal, moringa leaves, and bone meal. Water was provided ad libitum to all birds, and the feeding trial lasted for 4 months. Results revealed that the third diet was the most preferred by the local chickens. The diet significantly influenced the live weight of the chickens in the second month (P=0.000) and showed a significant effect during the third month (P=0.020) of the experiment. Sexual dimorphism was observed between hens and roosters for diets 2, 3, and 4. Statistical analysis indicated a significant difference in the Average Daily Gain of local chickens among the different treatments during the first month. Additionally, the diet significantly influenced the consumption index of local chickens during the first month of the experiment (P=0.055). Based on the findings, it is suggested that Diet 2, containing fish meal, can be utilized in areas where fish availability and accessibility are high. Conversely, Diets 3 and 4 may be more suitable for regions prone to locust infestations. To facilitate the adoption of these dietary formulations, it is recommended to replicate the experiments in rural settings.","PeriodicalId":495334,"journal":{"name":"Asian Journal of Research in Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141337560","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}

The study was conducted during December 2015 to November 2016. Samples were collected bi-monthly basis from three localities, namely; Um Aswad (Atbara River), El-Remila, and El-Monaba (Khashm El-Girba reservoir), using beach seine nets of 1.2 cm 4.0 cm and 7.0 cm stretched mesh. A total of 1595 O. niloticus specimens were collected from all sampling sites. The age of O. niloticus was estimated using five anterior vertebrae of fish body; The results indicate that the age ranged between 0+ to 4+ years. Most of the collected fish specimens were of age 1+, with females most dominant at this age. Sex ratio was 1:1(M: F). Gonado-somatic index (GSI) of females of O. niloticus ranged between 1.965 – 2.620, and from 0.434 – 0.439 for males. Two periods of increase of GSI were observed reflecting two breeding seasons of this species. Used gravimetric method to estimate the average fecundity of O. niloticus ranged between 481 eggs in Um Aswad sampling site, and 638 in El-Remila site. The fecundity of O. niloticus has a high correlation with gonadal weight (r=0.82708) but a low correlation with standard length (r=0.47612) and total weight (r=0.50874).\u0000The results of this investigation on O. niloticus indicate that the age of the fish ranged from 0+ to 4+ years, with a sex ratio of 1:1. The Gonado-somatic Index (GSI) indicated two spawning seasons, and fecundity was found to be strongly correlated with gonad weight, and moderately correlated with total length and standard length.

The nematode Trichinella spp causes serious zoonosis called trichinellosis, a disease affecting striated or skeletal muscles which consider as one of tropical disease. Even though its natural host varied, but infection among live stocks, such as pigs and other animals, which are raising public health concern. Human infection occurs after consumption of raw or undercooked meat or meat products contain muscle larvae of T. spiralis. The tropism of the parasite for individual striated muscles and/or striated muscle groups varies significantly. Trichinella spp. has a direct life cycle where all three life cycle stages (the infective muscle larvae, adult, and new born larvae) happen serially in one host only. Intestine-dwelling adults of Trichinella produce newborn larvae that bypass the enterocyte, enter the bloodstream and colonize skeletal muscle. The muscle larvae assemble excretory-secretory products which play crucial role in establishing and maintaining persistent parasitism and the host’s immune modulation and evasion. It turns out that excretory-secretory products from muscle larvae and mature worm also have hidden medical potential that can be used to treat allergic problems, inflammation-based diseases, autoimmunity and even malignancy. \u0000Conclusion: Trichinellosis is a serious and potentially fatal zoonosis which transmitted through consuming raw or uncooked contaminated meat or its comestibles. Its primary tropism is to the host’s striated muscle and infection can persist for a long time facilitated by several reciprocities of its product (e.g., excretory-secretory) with the host’s cell and immune system. Fortunately, there are several promising potency in the field of therapeutic and prevention medicine which should be explored intensely.","PeriodicalId":495334,"journal":{"name":"Asian Journal of Research in Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140973120","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}
