Small ruminant has great potential in enhancing the global food system, improving human health, and alleviating poverty.  Nevertheless, on average, small ruminant production has not been able to keep pace with the overall food demand globally. Meaning that without drastic action, the world food crisis will continue to persist and many people around the world will continue to live in abject poverty. To avert this ongoing phenomenon, this paper examines how the global food system and human health can be improved and poverty alleviated through small ruminant production; and how Nigeria will benefit from it. To properly articulate the theme of this paper, the discussion will focus on what small ruminant animals are; their benefits and constrain; the global food system, small ruminant production and its relation to human health and poverty eradication, efforts at improving small ruminant production and how this will have an impact on the Nigerian economy. Furthermore, the paper provides recommendations for the improvement of small ruminant production in Nigeria
小反刍动物在加强全球粮食系统、改善人类健康和减轻贫困方面具有巨大潜力。然而,平均而言,小型反刍动物的产量无法跟上全球总体粮食需求的步伐。这意味着,如果不采取严厉行动,世界粮食危机将继续存在,世界各地的许多人将继续生活在赤贫之中。为了避免这种持续的现象,本文探讨了如何通过小型反刍动物生产来改善全球粮食系统和人类健康并减轻贫困;以及尼日利亚将如何从中受益。为了恰当地表达本文的主题,讨论将集中在什么是小型反刍动物;他们的利益和约束;全球粮食系统、小反刍动物生产及其与人类健康和消除贫困的关系、改善小反刍动物生产的努力以及这将如何对尼日利亚经济产生影响。此外,本文还提出了改善尼日利亚小反刍动物生产的建议

The study was undertaken to ascertain effectiveness of use of ICTs by extension agents and arable crop farmers in Ido local government area Oyo State. Multiple stage sampling procedure was used to select 105 respondents for the study. Data were collected from the respondents through the use of structured questionnaire.. Descriptive statistics such as; mean, frequency table, and percentage were used to analysed data while inferential statistical tools such as Chi-square and Pearson Product Moment correlation (PPMC) were used to tested the hypotheses of the study. The result of the study showed that majority of the respondents were in the age bracket of 31-40 years, which could be categorized as adults, and more of them were males, while majority of them were married. Result revealed the level of ICTs used by extension agents for arable crop farmers were radio (97.1%), mobile phone (92.4%) and internet (81.9%).The result further shows major constraints militating the effectiveness of use of ICTs were network problem in the study area. There is no significant relationship between constraint and level of ICTs used by the arable crops farmer in the study area. It is therefore recommended that government should ensure that farmers should have access to and use ICTs by putting policies in place to ensure all rural area have access to ICTs tools ,also  awareness on the use of ICTs should be intensify among arable crop farmers.  
进行这项研究是为了确定Oyo州Ido地方政府地区推广人员和种植作物的农民使用信息通信技术的有效性。采用多阶段抽样方法,选取105名调查对象进行研究。通过使用结构化问卷从受访者中收集数据。描述性统计,例如;采用均值、频率表和百分比对数据进行分析,采用卡方和Pearson积差相关(PPMC)等推理统计工具对研究假设进行检验。调查结果显示,大多数受访者年龄在31-40岁之间,可以归类为成年人,男性居多,而且大多数是已婚人士。结果显示,农家推广人员使用信息通信技术的水平依次为无线电(97.1%)、移动电话(92.4%)和互联网(81.9%)。研究结果进一步表明,影响信息通信技术使用效率的主要制约因素是研究地区的网络问题。研究区耕地农户信息通信技术使用水平与约束之间无显著相关。因此,建议政府应制定政策,确保所有农村地区都能使用ict工具,确保农民能够接触和使用ict,并加强种植作物的农民对ict使用的认识。

The study analyzed the socio-economic determinants of net-income in aquaculture of Kainji, Lake Basin, Nigeria. Specifically, the study examined the; fish farming systems; cost and returns, socio-economic determinants of net-farm income and challenges of fish farming in the area. The study adopted a two-stage sampling procedure to select 120 table-size fish farmers. Data were collected with questionnaires that were administered through face-to-face interview and analyzed using descriptive statistics, budgetary technique and multiple regression analysis. The results showed that 35.00 % of the fish farmers were within the age bracket of 31-40 years, 53.34 % were men, 91.67 % were married, 55.83 % had between 1-5 years of experience in fish farming and 75.83 % had tertiary educational qualification. Majority (92 %) of the fish farmers practiced the monoculture of catfish using earthen ponds system. The estimated total expenses were N 14,953,330.74 while the total revenue generated from 9 fish ponds, each stocked with an average of 3883.986 fingerlings in 2 cycles per year was N 20,188,142.00. The estimated net-farm income after tax was N 5,234,811.26 while the net profit margin and return on investment was 25.93 % and 35% respectively. Age, experience and household size were positive and significant (p<0.05) socio-economic factors that affected net-farm income while the challenges of fish farming were high cost of feed ( ̅x=3.24), poor pricing ( ̅x =3.11), poor access to capital ( ̅x=3.09) and persistent poaching/theft ( ̅x= 2.67). Based on the findings of the study, it is recommended that there should be an intensive research by the fish nutrition division of National Institute for Freshwater Fisheries Research (NIFFR) on the possible alternatives of crude protein source that could be a perfect substitute to Clupeids in fish feeds. Keywords: aquaculture, catfish, socio-economic, profitability, farmers
该研究分析了尼日利亚Kainji湖流域水产养殖净收入的社会经济决定因素。具体来说,该研究调查了;养鱼系统;成本和收益、净农场收入的社会经济决定因素以及该地区养鱼面临的挑战。该研究采用两阶段抽样程序,选择了120个餐桌大小的养鱼户。通过面对面访谈的问卷调查收集数据,并使用描述性统计、预算技术和多元回归分析进行分析。结果表明,35.00%的养鱼户年龄在31-40岁之间,53.34%为男性,91.67%已婚,55.83%具有1-5年养鱼经验,75.83%具有高等教育学历。大多数养鱼户(92%)采用土塘系统单一养殖鲶鱼。估计总费用为14,953,330.74挪威元,而9个鱼塘(每个鱼塘每年2个周期平均放养3883.986只鱼种)产生的总收入为20,188,142.00挪威元。估计税后净农场收入为5,234,811.26奈拉,净利润率和投资回报率分别为25.93%和35%。年龄、经验和家庭规模是影响养殖场净收入的积极且显著(p<0.05)的社会经济因素,而鱼类养殖面临的挑战是饲料成本高(指数x=3.24)、定价差(指数x= 3.11)、难以获得资金(指数x=3.09)和持续的偷猎/盗窃(指数x= 2.67)。在此基础上,建议国家淡水渔业研究所鱼类营养部门深入研究可作为鱼饲料中粗蛋白质的理想替代品。关键词:水产养殖;鲶鱼;社会经济

The main purpose of this study was to analyze the awareness of information and communication technologies (ICTs) among yam farmers in Ikom Agricultural Zone, Cross River State, Nigeria. The specific objectives were to; identify the types of ICTs available to yam farmers, ascertain the level of awareness of ICTs among yam farmers and ascertain the effects of ICTs on yam production in the study area. Questionnaires were used to obtain data from respondents for the study. Data were analyzed using descriptive statistics such as frequency, percentage, mean and ranks. Result of types of ICTs available among the yam farmers showed that radio was ̅=3.70, Mobile phones were ̅=3.50 while television had ̅=3.11 and were the most available ICTs accessed by yam farmers in the study area. Findings on the level of awareness indicated that Radio ( ̅=1.78) ranked 1st, television ( ̅=1.70) ranked 2nd while, mobile phone ( ̅=1.66) ranked 3rd and were the ICTs that the farmers had greater awareness. Results on the perceived effects of ICTs on yam production revealed that ICTs reduce cost of interaction among yam farmers, enhanced decision-making among farmers and also strengthen partnership with research and extension. However, serious constraints to the use of ICT facilities by farmers were identified such as; poor finance, erratic power supply and cost of use of ICT tools. The result of this study showed that yam farmers in Ikom Agricultural Zone utilized conventional ICTs tools more than contemporary tools in yam production. The study therefore concluded that, there is a commendable level of awareness of information and communication technologies among yam farmers in Ikom Agricultural Zone of Cross River State, Nigeria.
本研究的主要目的是分析尼日利亚克罗斯河州Ikom农业区山药农民对信息和通信技术(ict)的认知。具体目标是:确定向山药农民提供的信息通信技术类型,确定山药农民对信息通信技术的认识水平,并确定信息通信技术对研究地区山药生产的影响。调查问卷是用来获取调查对象的数据。数据分析采用描述性统计,如频率,百分比,平均值和排名。研究区山药农户可利用的信息通信技术类型分析结果显示,无线电通信为3.70,移动电话为3.50,电视为3.11,是研究区山药农户可利用最多的信息通信技术。调查结果显示,农民对信息通信技术(ict)的认识程度最高的是广播(1.78),其次是电视(1.70),第三是手机(1.66)。关于信息通信技术对山药生产的感知效应的研究结果显示,信息通信技术降低了山药农民之间的互动成本,增强了农民之间的决策,并加强了研究和推广方面的伙伴关系。然而,农民使用信息通信技术设施的严重制约因素被确定为:资金不足、电力供应不稳定以及信息通信技术工具的使用成本。这项研究的结果表明,Ikom农业区的山药农民在山药生产中更多地使用传统的信息通信技术工具,而不是现代工具。因此,这项研究的结论是,尼日利亚克罗斯河州Ikom农业区的山药农民对信息和通信技术的认识程度值得赞扬。

The study examined the fish farmers‟ perceived environmental effects of dam operation and coping strategies among fish farmers in Ikere George dam, Iseyin Oyo state. Multi stage sampling technique was used to select 102 respondents in the study area. Data were collected through the use of interview schedule and were analysed using descriptive statistics such as percentage and frequency, while chi-square and PPMC were used to analyse hypotheses at p < 0.05. The result revealed that majority (54%) of the respondents below 40 years, with males predominantly higher than females. Also, 71.6% were married and 58.8% had educational attainment below secondary school. Challenges identified were disruption of movement of aquatic animals (137), blockage of migrations of aquatic species (135) and problem of overcrowding in the community (129) were prominent perceived effects of dam operation. The result further showed that migration (99) and planting of trees (146) were the most commonly used coping strategies. Chi-square showed that there was significant relationship between socio-economic characteristics of the respondents and perceived effects of dam operation except religion which was not significant (p>0.05). PPMC analysis revealed that there was significant relationship between coping strategies used (r=0.687, p=0.000). It is therefore recommended that proper training and adequate facilities should be given to fish farmers to ensure sustainability of the dam.
该研究调查了Iseyin Oyo州Ikere George大坝养鱼户对大坝运行的环境影响和应对策略。采用多阶段抽样方法,在研究区抽取102名调查对象。采用访谈计划收集资料,采用百分比、频次等描述性统计进行分析,采用卡方和PPMC进行假设分析,p < 0.05。调查结果显示,大多数受访者(54%)年龄在40岁以下,男性的年龄明显高于女性。此外,71.6%的人已婚,58.8%的人受教育程度在中学以下。确定的挑战是水生动物运动的中断(137),水生物种迁徙的阻碍(135)和社区过度拥挤的问题(129)是大坝运行的突出影响。结果进一步表明,迁移(99)和植树(146)是最常用的应对策略。卡方分析显示,除宗教信仰外,被调查者的社会经济特征与大坝运行效应感知存在显著相关(p>0.05)。PPMC分析显示,大学生应对策略的使用与应对策略之间存在显著相关(r=0.687, p=0.000)。因此,建议向养鱼户提供适当的培训和适当的设施,以确保大坝的可持续性。

This study examines the consumer’s perception of white meat among household in Ibadan north local government area of Oyo state, Nigeria. Multi-stage sampling was used through questionnaire to gather information from 110 respondents used as a sample size for the study. Data were analyzed through the use of descriptive statistics tools such as frequency and percentage, while inferential statistics such as chi-square and PPMC were used for the hypotheses. The result of the study revealed that majority (63.6%) of the respondents were married, also in their active age (93.2%) and engaged in trading and civil service work as their primary occupation. Also, majority (55.5%) had up to secondary education and tertiary school level with household size 1-5.The result further revealed that 52.4% of the respondents had unfavourable perception of white meat consumption while 47.6% had favourable perception. Also, better cholesterol content (53.6%) and reduced health risk (51.8%) were some of the perceived benefits of white meat considered by respondents. Constraints such as high cost of white meat (99%) and low income (88%) were considered as major constraints to white meat consumption. Chi-square analysis revealed that marital status(X2=18.693, P=0.028), education(X2=17.753, P=0.038) and primary occupation(X2=18.266, P=0.032) of respondents were found to have significant relationship with their perception of white meat consumption at 0.05 level. Also, PPMC analysis showed that there was relationship between perceived benefits and perception for white meat at 0.05 level of significant. The study, therefore, recommends that the enlightenment programmes on nutritional benefit of white meat consumption should be promoted for consumers to have right perception.
本研究调查了尼日利亚奥约州伊巴丹北部地方政府地区家庭中消费者对白肉的看法。采用多阶段抽样,通过问卷调查收集110名受访者的信息,作为研究的样本量。数据分析通过使用描述性统计工具,如频率和百分比,而推断统计,如卡方和PPMC用于假设。研究结果显示,大部分(63.6%)受访者已婚,亦处于活动年龄(93.2%),主要职业为贸易或公务员工作。此外,大多数(55.5%)家庭人口为1至5人,拥有中等及以上学历。调查结果进一步显示,52.4%的受访者对白肉消费持负面看法,47.6%的受访者对白肉消费持正面看法。此外,更好的胆固醇含量(53.6%)和降低健康风险(51.8%)是受访者认为的白肉的一些好处。白肉成本高(99%)和收入低(88%)等制约因素被认为是白肉消费的主要制约因素。卡方分析显示,被调查者的婚姻状况(X2=18.693, P=0.028)、受教育程度(X2=17.753, P=0.038)和主要职业(X2=18.266, P=0.032)与他们对白肉消费的认知存在显著关系(0.05水平)。此外,PPMC分析显示,感知效益与对白肉的感知之间存在显著的相关性,在0.05水平上。因此,本研究建议应推广有关白肉营养价值的启蒙项目,使消费者有正确的认识。

The study was carried out to determine profitability of broiler production in Cross River State, Nigeria. A three stage multi sampling technique was adopted in the selection of 180 respondents. Data collected were analysed using descriptive statistics such as frequency, mean, ranking and percentages, as well as budgeting techniques tools such as net farm income (NFI), return to naira invested (RNI), gross and operating ratios (GR and OR) respectively. Result of analysis showed that socio-economic attributes of broiler farmers - age, sex, marital status, education, experience, business size and training studied influenced on broiler production in the area. Furthermore, the study revealed that broiler production is a profitable venture in the area. This is arising from the difference between a total revenue of N704, 000 and total cost of N419, 153 respectively, representing a net profit of N284, 646.6 or 67.90% of the total amount of money invested, within a production season of eight weeks. The return per naira invested ratio was 1.64, this meant that for every naira invested, N1.64 profit was made by the broiler farmer, this further indicated that the business is profitable. The gross ratio, which measured the overall financial success of the business recorded 0.61. However, cost of feeds, lack of extension services, financial constraints, cost of day old chick’s medication among others are the constraints affecting effective broiler production in the area. Based on the findings of this study, the following are recommended: regular extension training on broiler production should be carried out by the relevant government agencies, feeds should be subsidized and made easily available by government, production of day old chicks should be subsidized by government to cushion the effect of their high cost and livestock farmers should be encouraged to invest on the poultry subsector for it profitability.
开展这项研究是为了确定尼日利亚克罗斯河州肉鸡生产的盈利能力。在180名受访者的选择中,采用了三阶段多抽样技术。收集的数据分别使用描述性统计数据(如频率、平均值、排名和百分比)以及预算技术工具(如农场净收入(NFI)、投资奈拉回报率(RNI)、毛利率和营业利率(GR和OR))进行分析。分析结果表明,肉鸡养殖户的社会经济属性——年龄、性别、婚姻状况、教育程度、经验、经营规模和培训对该地区肉鸡生产有影响。此外,研究表明,肉鸡生产在该地区是一项有利可图的投资。这是由于总收入为704,000奈拉和总成本为419,153奈拉之间的差异造成的,在八周的生产季节内,净利润为N284, 646.6或投资总额的67.90%。每奈拉投资回报率为1.64,这意味着每奈拉投资,肉鸡养殖户获得N1.64利润,这进一步表明该业务是有利可图的。衡量企业整体财务成功的毛利率为0.61。然而,饲料成本、推广服务的缺乏、财政限制、日龄雏鸡用药成本等是影响该地区有效肉鸡生产的制约因素。根据本研究结果,建议:相关政府机构应定期开展肉鸡生产推广培训,政府应补贴饲料并使其易于获得,政府应补贴日龄雏鸡的生产以缓冲其高成本的影响,并鼓励畜牧农民投资家禽分行业以获得盈利。

Chicken weed is a significant weed in India and it occurs under onion cultivated field at Birnin Kebbi in the Sudan Savannah, Nigeria. On-farm experiment was conducted at Birnin Kebbi during the 2017/2018 and 2018/2019 dry season to evaluate the effect of plant population and weed control methods on the management of chicken weed (Portulaca quadrifida) alongside other weeds in onion field. The experiment consisted of three plant populations (500,000, 333,333 and 250,000 plants per hectare) and twelve weed control methods (Pendimethalin at 1.0 kg a.i. ha-1, + 1Hw; pendimethalin at 1.5 kg a.i. ha-1 + fluazifop-p-butyl at 2.0 kg a.i. ha-1; pendimethalin at 2.0 kg a.i. ha-1; butachlor at 2.0 kg a.i. ha-1 + 1Hw; butachlor at 2.8 kg a.i. ha-1 + oxyfluorfen at 1.0 kg a.i. ha-1; butachlor at 3.6 kg a.i. ha-1; fluazifop-p-butyl at 2.0 kg a.i. ha-1; oxyfluorfen at 1.0 kg a.i. ha-1 + 1Hw; hoe weeding at 3 (WAT); hoe weeding at 3 and 6 WAT; weed free and weedy check). The experiment was laid out in a randomized complete Block design replicated three times. Results showed that weed, growth and yield parameters were not significantly affected by plant population. Pendimethalin at 1.5 kg a.i. ha-1 + fluazifop-p-butyl at 2.0 kg a.i. ha-1 and weed free plots consistently recorded the lowest weed cover and highest weed control efficiency. Butachlor at 2.0 kg a.i. ha-1 + 1 Hw recorded the lowest crop injury score. Increase in plant height was observed when pendimethalin at 1.0 and 1.5 kg a.i. ha-1 + 1 Hw and fluazifop-p-butyl at 2.0 kg a.i. ha-1 respectively was applied, while application of pendimethalin at 2.0 kg a.i. ha-1 and butachlor at 2.0 kg a.i. ha-1 + 1 Hw recorded highest number of leaves and leaf area. Cured bulb and marketable bulb yield were greater with the use of pendimethalin and butachlor at 1.0 and 1.5 kg a.i. ha-1 + 1 Hw and the pooled data respectively. Application of pendimethalin and butachlor at the rate of 1.0 and 2.0 kg a.i. ha-1 followed by 1 Hw at 6 WAT respectively was therefore recommended for the control of chicken weed alongside other weed species in the ecology
鸡草在印度是一种重要的杂草,它发生在尼日利亚苏丹大草原Birnin Kebbi的洋葱栽培地里。在2017/2018和2018/2019旱季,在Birnin Kebbi进行了农场试验,以评估植物种群和杂草控制方法对洋葱田鸡杂草(Portulaca quadriida)和其他杂草管理的影响。试验包括3个植物种群(50万、33万、33万、25万株/公顷)和12种杂草防治方法(喷施甲氧苄啶1.0 kg a.i. ha-1, + 1Hw;戊二甲基灵1.5 kg A.I. ha-1 +氟唑磷-对丁基2.0 kg A.I. ha-1;二甲基甲烷2.0 kg A.I. ha-1;丁草胺2.0 kg a.i. ha-1 + 1Hw;丁草胺2.8 kg A.I. ha-1 +氟氯醚1.0 kg A.I. ha-1;丁草胺3.6 kg A.I. ha-1;氟唑磷-对丁基2.0 kg A.I. ha-1;氟氧虫1.0 kg a.i. ha-1 + 1Hw;锄草在3 (WAT);锄草在3点和6点;无杂草和杂草检查)。实验采用随机完全块设计,重复三次。结果表明,植物种群对杂草、生长和产量参数的影响不显著。施用1.5 kg a.i. ha-1的二甲醚+施用2.0 kg a.i. ha-1的氟唑磷-对丁基与无杂草样地的杂草覆盖最低,防杂草效率最高。施用2.0 kg a.i. ha-1 + 1 Hw的丁草胺对作物的伤害评分最低。分别施用1.0和1.5 kg a.i. ha-1 + 1 Hw和2.0 kg a.i. ha-1氟唑磷-对丁基时,株高均有显著提高,而施用2.0 kg a.i. ha-1和2.0 kg a.i. ha-1 + 1 Hw时,叶数和叶面积最高。二甲甲烷和丁草胺分别在1.0和1.5 kg a.i. ha-1 + 1 Hw和汇总数据下使用,固化球茎和市售球茎产量更高。因此,建议分别以1.0 kg a.i. ha-1和2.0 kg a.i. ha-1的速度施用对甲脒和丁草胺,然后以6 WAT的速度分别施用1 Hw,以控制鸡杂草和生态系统中的其他杂草

Credit rationing by deposit money banks and implication on agricultural output in Nigeria 存款银行的信贷配给及其对尼日利亚农业产出的影响
Pub Date : 2020-10-30 DOI: 10.4314/gjass.v19i1.8

The study examined the effects of credit rationing by deposit money banks on the performance of agriculture in Nigeria using secondary data between 1981 and 2016 obtained from the CBN Statistical bulletin. The study applied both Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root test to determine the order of integration of each variable, Johansen cointegration and Vector Error Correction Model (VECM) were employed to determine if there is a long run, the short-run relationship between credit rationing and agricultural output. The result showed that all the variables were integrated of order one. The results revealed that credit rationed for fishery has a short-run significant impact on agricultural output while credit rationed for cash crops, food crops, and livestock do not have a significant short-run impact on agricultural output. The findings further revealed that credit rationed for cash crops and livestock farming significantly decline agricultural output to the tune of 26.48% and 75.87% in the long run while credit rationed for food crops and fishery significantly result in 43.52% and 41.89% rise in agricultural output in the long run. Therefore, the study recommends the establishment of special financial institutional to give unconditional loans to farmers, raise credit rationing for food crop production above the current ceiling, and emphasis should be on exchange rate liberalization policy that will shift consumption from imported agricultural produce to local agricultural produce. These measures will promote farmers’ access to funding which will invariably translate to a rise in agricultural output.
该研究使用从CBN统计公报获得的1981年至2016年的二手数据,研究了存款银行信贷配给对尼日利亚农业绩效的影响。本研究采用ADF (Augmented Dickey-Fuller)和PP (Phillips-Perron)单位根检验来确定各变量的积分顺序,采用Johansen协整和VECM (Vector Error Correction Model)来确定信贷配给与农业产出之间是否存在长期、短期关系。结果表明,所有变量都是1阶的积分。结果表明,渔业信贷配给对农业产出有短期显著影响,而经济作物、粮食作物和畜牧业信贷配给对农业产出没有显著的短期影响。研究结果进一步表明,经济作物和畜牧业的信贷配额在长期内显著降低了农业产量,分别为26.48%和75.87%,而粮食作物和渔业的信贷配额在长期内显著提高了农业产量,分别为43.52%和41.89%。因此,报告书中建议,设立向农民无条件提供贷款的特别金融机构,将粮食生产的信贷配给量提高到目前的最高限额以上,并强调将消费从进口农产品转向国产农产品的汇率自由化政策。这些措施将促进农民获得资金,这将不可避免地转化为农业产出的增加。

Ecology and population dynamics of silver catfish, Chrysichthys nigrodigitatus (Siluriformes: Claroteidae), of the Cross River, Nigeria 尼日利亚克罗斯河银鲶鱼的生态学和种群动态
Pub Date : 2020-10-30 DOI: 10.4314/gjass.v19i1.9

Chrysichthys nigrodigitatus forms the most commercially important freshwater single species fishery in the Cross River, Nigeria. Studies were conducted on the dynamics of the exploited population of the species and the influence of rainfall on its catch rate. The objectives were to assess the level of exploitation and impacts of rainfall on its catch rate. A time series of length frequency and meteorological parameters was conducted. Length frequency data were analyzed using FiSAT software to estimate population parameters. The asymptotic length, L was 105 cm, growth constant (K) was 0.68 year -1 , total mortality (Z) was 2.48 year -1 , Natural mortality (M) was 0.99 year -1 and fishing mortality (F) was 1.49 year -1 . The exploitation rate was 0.60 year -1 , indicating overfishing. Natural mortality accounted 40% of the total mortality, presenting a worrisome trend in the fishery. There was a correlation between rainfall and catch rate, which increased at the onset of rains but decreased at the peak of the rains due to increased depth of the river. For management purposes, it is recommended that the fishing effort should be reduced by the regulation of the number of boat-days; for conservation, domestication of the species should be adopted as an adaptation to climatic influence.
黑尾蝶是尼日利亚克罗斯河最具商业价值的淡水单种渔业。研究了该物种被捕捞种群的动态以及降雨对其捕捞率的影响。目的是评估开发水平和降雨对其捕获率的影响。进行了长度、频率和气象参数的时间序列分析。使用FiSAT软件对长度频率数据进行分析,估计种群参数。渐近体长L为105 cm,生长常数K为0.68年-1,总死亡率Z为2.48年-1,自然死亡率M为0.99年-1,捕捞死亡率F为1.49年-1。捕捞率为0.60 -1,表明过度捕捞。自然死亡率占总死亡率的40%,呈现出令人担忧的渔业趋势。降雨量与捕获率之间存在相关性,在降雨开始时增加,但在降雨高峰时由于河流深度增加而减少。为了管理的目的,建议通过规定船日的数目来减少捕鱼努力量;为了保护该物种,应采取驯化措施,以适应气候影响。
