Due to the generation of income and jobs, this species is extremely significant to Senegal’s socioeconomic landscape, especially in the Dakar area. This work constitutes a first study on the population dynamics of Perna perna in Senegal. The specimens used for this study were caught in the Mamelles site on the Cape Verde Peninsula from March 2018 to February 2019. To assess population parameters, the FiSAT II software and its ELEFAN sub-program were used to analyze the monthly length-frequency data. The results obtained show that the asymptotic length (L∞), growth coefficient (K), growth performance index (Φ’) and longevity (tmax) were 13.65 cm, 1 yr-1, and 2.27; 2.80 yr, respectively. Total mortality (Z) was esteemed to be 3.51 yr-1. Natural mortality (M) and fishing mortality (F) were 2 yr-1 and 1.51 yr-1, respectively. The recruitment pattern is a continuous with a major peak occurring in May-Jun. The current exploitation level (E) of Perna perna was 0.43 while the maximum allowable limit of exploitation (Emax) was 0.453; which implies that in order to prevent overexploitation, management actions will need to be taken.","PeriodicalId":481204,"journal":{"name":"Scholars journal of agriculture and veterinary sciences","volume":"108 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141666027","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 aim of the study was to determine the effects of cryptoprotectants on cockerel semen preservation. A total of twelve (12) indigenous cockerels with ages ranging from 12 to 15 months, with an unknown previous management background from local markets in Kashere were used. The cockerels were managed intensively and put into pens as experimental units. Cockerels were fed daily with growers mash feed and served water ad libitum; the birds were trained once a day in the morning by abdominal massage for two weeks. The cockerels were randomly allotted into three treatments. Each treatment had 3 replicates. The indigenous cockerels were trained once a day and semen was collected between 10:00am and 11:00am. The cockerels were allowed a period of two week for adaptation, Semen were collected by abdominal massage method described by Burrows and Quinn (1937). The semen concentration were measured using haemocytometer with the direct cell count method. The coconut water was collected from a freshly harvested coconut plant. Five milliliters of the coconut water was placed into different sampling bottles and diluted with different percentages of glycerol.

Some of these transformations are due to changes in human activity, resulting from unsuitable cultivation practices, and overexploitation of the land, which is accompanied by a decline in cultivated soils fertility. A baseline survey was conducted to diagnose cotton-grown soils in terms of fertility and long-term sustainable utilization. Six locations were selected in the vast cotton cultivation zone in northern Côte d’Ivoire. Soil pH varied from slightly acidity to neutral, suggesting good acidity level for optimum cotton growth. However, there were deficiencies in nutrients, which differed from one soil to another: soil organic carbon was lower than 5 %, total N was very low in Boundiali and Korhogo, and soil assimilable phosphorous was very low in Boron, Diawala and Ferkessédougou. Soil grouping using a principal component analysis showed some similarities among the studied cotton-grown soils and constitutes a clue to align soils fertilization strategies. The analysis of soil amendments should focus on macronutrient and specific secondary nutrients like Ca, S, and Mn input. Furthermore, cotton-grown soils fertilization should be done through organic amendment.","PeriodicalId":481204,"journal":{"name":"Scholars journal of agriculture and veterinary sciences","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135804426","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}

Questionnaire was used to collect data from 460 respondents. Multi-stage and proportionate sampling techniques were used in selecting the respondents. Descriptive statistical tools (frequency distribution, percentages, mean and ranking) were used for data analysis. The results of the study showed that majority of the respondents were male (82.2%) and were within the age (51.3%) bracket of 29-41years, indicating that respondents were middle aged fishers who fall within the active fishing age. Majority (87.0%) of the fishers were married with an average household size of 6 persons. The study found out that the constraints faced by the fishers to include high cost of fishing gear (72.8%) which is the most serious constraint, closely followed by lack of credit facilities (50.7%) and lack of modern equipment (50.2%). The findings on interventions received by the fisher’s shows that majority of the respondents (44.4%) received fishing gears, closely followed by improved market structures (37.6%) and provision of roads linking villages (37.2%). Findings on the strategies towards the development of artisanal fisheries reveal that (70.9%) fishers ranked 1st supported enhanced extension service delivery, (67.8%) respondents’ ranked 2nd suggested provision of credit facility and (55.4%) respondent’s ranked 3rd supported provision of processing facilities. Conclusively, the research showed that, fishing activity is an important livelihood activity in the lives of the fishers along the two dams. The constraints that faced the industry such as high cost of fishing gears, lack of credit facilities etc hindered full realization of the potentials of the industry. The study therefore, recommended that financial institutions should grant credit facilities to fishers and their educational level should be improved.","PeriodicalId":481204,"journal":{"name":"Scholars journal of agriculture and veterinary sciences","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135721007","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}

Walp) production in Nigeria is burdened by insect pest infestations throughout its developmental stages. Farmers rely on the use of conventional insecticides for insect pest control; however, these insecticides are often wrongly used, thereby resulting in undesirable effects on seed yield and the ecosystem. Cowpea was cultivated under different insecticide application regimes and its effect on seed production was evaluated at three substations of the Institute of Agricultural Research and Training, located at Ibadan in Oyo state (Rain forest transiting to derived savannah), Ilora in Oyo state (Derived savannah) and Ballah in Kwara state (Southern Guinea savannah). The trial was conducted during the cowpea cropping seasons of year 2018 and 2019. Ten treatments included 10 sprays of 2.5 EC lambda-cyhalothrin and cowpea varieties Ife Brown and IT2246. The experimental layout was split-split plot in a randomised complete block design. The results show a reduction in percentage aphids infestation as the spraying regimes increased on both cowpea varieties. The lowest values of 1.53 and 1.58% on Ife Brown and IT2246 respectively, were recorded on 200m/ha of four regime spray. Similar results were recorded on the number of thrips, the population of Clavigralla spp and number of pods/plant. Average seed yield under 3 spraying regime increased for both Ife Brown and IT2246 with increase in concentration of pesticide across locations except Ibadan where the yield reduced when the concentration was increased to 600 ml/ha. The spraying regimes of Lambda-cyhalotrin at foliage, flowering and podding have considerable potential for managing the pest of cowpea, but their impact of cowpea grain yield varies significantly.","PeriodicalId":481204,"journal":{"name":"Scholars journal of agriculture and veterinary sciences","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485534","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}
