This study provides the first results on fishery dynamics of the species in the reservoir. The study was aimed at estimating important population dynamics parameters and production potential. Total length (TL) and total weight (TW) data were collected from a total of 276 fish samples (141 females and 135 males). The obtained data were analyzed using FiSAT II software. Jones length-based cohort analysis model and length-based Thompson and Bell yield prediction models were employed to estimate the population and production potential. The mean total length was 26 cm and the dominant length groups ranged from 17 to 33 cm were 87%. The length-weight relationship parameters were (TW = 0.0565TL2.53, R2 = 0.95) and the condition factor K = 1.29.

The estimated values of the total, natural and fishing mortalities were Z = 1.23, M = 0.55 and F = 0.68, respectively. The current exploitation rate was 0.55 which indicates slightly overexploitation. The estimated fish population and the annual fish yield were 59,304 and 1.5 tons, respectively. However, investigation on reproductive biology, limnolocal aspects and stock enhancements should be required for the sustainability of these resources.","PeriodicalId":294884,"journal":{"name":"East African Journal of Biophysical and Computational Sciences","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129723833","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}

This is because it ensures the safety of meat and consumers’ health. However, the meat sector is still underdeveloped in most African countries. In addition, there is limited research addressing meat safety challenges. In Uganda particularly, in the recent past, there was whistle-blowing over contaminated beef on the market, indicating a  loophole in food safety. Despite this, studies focusing on beef handling practices have remained scanty. Thus, this study aimed to examine beef handling practices at the abattoirs and butcher shops in Uganda's Central, Western, and Eastern regions. A mixed-methods approach was employed to collect data through a survey, in-depth interviews, and on-site observations. Findings revealed that beef handling practices were poor at abattoirs and butcher shops and that most facilities for safety measures were lacking or inadequate. Only 3% of the respondents had cold room storage facilities, and meat spoilage was relatively high (85.3%). Appropriate knowledge of meat safety among abattoir and butcher operators was inadequate, contributing to low compliance with food safety guidelines. Inappropriate handling practices and poor handling facilities may put consumers at a health risk. The study recommends that responsible authorities should ensure compliance mechanisms and sensitization initiatives are prioritized.","PeriodicalId":294884,"journal":{"name":"East African Journal of Biophysical and Computational Sciences","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124564465","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}

In doing so, the basic idea is to first rewrite the problem as a variational equation, and then seek a solution approximation from the space of continuous piece-wise linear’s. This discretization procedure results in a linear system that can be solved by using a numerical algorithm for systems of these equations. The techniques are based on the finite element approximations using Galerkin’s method in space resulting system of the first order ODE’s and then solving this first order ODE’s using backward Euler descritization in time. For the two-dimensional problems, we use the ODE solver ODE15I to descritize time. The validity of the numerical model is verified using differenttest examples.

So far data on plant species composition and perception of university towards landscape work is lacking. With this understanding, the study was conducted to investigate plant species composition and community perception towards landscaping work executed at Hawassa University’s main campus using questionnaires, interviews, observation and group discussion methods. In addition, vegetation data were collected using systematic sampling method. In the study, 221 respondents were drawn from academic staff, administrative workers and students using random sampling method. Key informants were selected using purposive sampling method. In order to identify the plant species, systematic sampling along the transect line was employed. Twelve (12), 40m X 40 m  (i.e. 1600 m2) area quadrat plots were laid and all the plants species in the quadrats were collected and identified. The distance between each transects and quadrat was 200 m and 100m, respectively. 52 plant species with 44 genera and 29 families were recorded. The study showed that, the most dominant family was Fabaceae with 9 species followed by Cupressaceae as well as Moraceae with 4 species each respectively. The results revealed that, campus landscaping work was the most significantly important and made the campus more attractive by plantation (61.1%), landscaping (27.1%) and walkways (5.7%). Plantation could also modify the micro-climate of the campus environment (94.3%) due to the plants photosynthesis process which produces O2 and takes in Co2 from the atmosphere.

Of the selected and examined sheep 132 (31.3%, 95% CI=26.8-35.7) were found infected by Eimeria species. The prevalence of Eimeria infection was significant (P <0.05) higher in lambs/young than the adult, in females than males, and in poor body condition than in medium body condition sheep. Moreover, the prevalence of Eimeria infection was significantly (P <0.05) higher in sheep with soft faeces than in normal faeces sheep and semi-intensive than extensive sheep production. The intensity of Eimeria species infection was influenced by the age, sex, body condition, fecal consistency, and production system of sheep (P< 0.05). The overall mean Oocysts per gram of faeces was 2390.6 (95% CI=2007.5-2773.8). The mean OPG was significantly higher in lambs, with poor body conditions and female sheep. In addition, it was higher in sheep with soft faeces and an extensive production system. In conclusion Eimeria species infection was an important problem of sheep production in the study area.
