Aims: To differentiate morphologically and functionality of chitin bodies belong to Necator americanus (old world hook worm) vs. 2 pair of teeth belong to Ancylostoma duodenale (new world hook worm) Discussion: Anemia due to hookworms caused by persistent blood loss. Those micro-bleeding occurs due to the attachment to the villi of the host’s small intestine in order to facilitate feed on their host’s blood. Hookworms use their two pairs of teeth (A. duodenale) or cutting plates called chitin bodies (N. americanus) to fasten their attachment onto the mucosa and submucosa, where at the same time they secrete a series of biochemically active polypeptides that prevent blood from clotting and supress the host inflammatory response. Differences in the shape of teeth or similar apparatus in the two species of hookworms that infect humans play a role in the occurrence of persistent minor bleeding that causes anemia and this also depend on the number of hookworms invaded the host. Conclusion: chitin bodies of N. americanus causes less bleeding than two pairs of teeth belongs to A. duodenale
目的:从形态和功能上区分属于旧世界钩虫(Necator americanus)的几丁质体与属于新世界钩虫(Ancylostoma duodenale)的两对齿:钩虫引起的贫血是由持续失血造成的。钩虫附着在宿主的小肠绒毛上,以便于吸食宿主的血液,从而导致微量出血。钩虫利用其两对牙齿(十二指肠钩虫)或称为几丁质体的切割板(美洲钩虫)将其附着物固定在粘膜和粘膜下层,同时分泌一系列具有生化活性的多肽,防止血液凝固并抑制宿主的炎症反应。感染人类的两种钩虫在牙齿或类似装置形状上的差异在发生持续性轻微出血并导致贫血方面起着一定作用,这也取决于侵入宿主体内的钩虫数量。结论:美洲钩虫的几丁质体比属于十二指肠钩虫的两对牙齿引起的出血更少。

Aims: The study aims to study the resource partitioning and nesting behaviour in four species namely Common Myna, Bank Myna, Brahminy Starling, and Asian Pied Starling nesting in human settlements. Place and Duration of Study: The study was conducted from January 2022 to July 2023 in peri-urban areas of Ajmer city, Rajasthan, India. Methodology: Using observations and point-count transects, we examined the nesting preferences, heights, and materials used by these species. Results: The findings reveal that all four species demonstrated a remarkable adaptability to urban environments by selecting man-made structures as their preferred nesting sites. Common Mynas, in particular, displayed a preference for a variety of human constructions, such as buildings and building cracks, and utilized materials like twigs, straws, plastic, paper, and cotton. Conclusion: This study highlights the importance of considering wildlife adaptation in urban planning and conservation efforts, as these birds thrive in human-altered landscapes. The nesting behaviors and adaptation of these Sturnidae species in urban environments reveal their ability to coexist with human development. Understanding these interactions is crucial for both avian ecology and urban planning, as it sheds light on the intricate relationships between wildlife and changing landscapes.
目的:研究人类住区中普通八哥、Bank八哥、Brahminy椋鸟和Asian Pied椋鸟的资源分配和筑巢行为。 研究地点和时间:研究于2022年1月至2023年7月在印度拉贾斯坦邦Ajmer市的近郊地区进行。 方法:通过观察和点计数样带,我们研究了这些物种的筑巢偏好、高度和使用的材料。 结果:这4个物种都对城市环境表现出了显著的适应性,它们选择人工建筑作为首选的筑巢地点。特别是普通的Mynas,表现出对各种人类建筑的偏好,比如建筑物和建筑裂缝,并利用树枝、稻草、塑料、纸和棉花等材料。 结论:这项研究强调了在城市规划和保护工作中考虑野生动物适应的重要性,因为这些鸟类在人类改变的景观中茁壮成长。这些鱼科物种的筑巢行为和对城市环境的适应揭示了它们与人类发展共存的能力。了解这些相互作用对鸟类生态学和城市规划都至关重要,因为它揭示了野生动物与不断变化的景观之间的复杂关系。

Naturally breeding fish cannot meet the demand of humans. So induced breeding is essential to fulfill this demand. Induced breeding ensures a timely supply of fish seeds having desired characteristics and different techniques can be used for this purpose. In this perspective synthetic hormones, extracts of pituitary hormones, Gonadotropin-releasing hormones, and sometimes Human chronic gonadotropin are used as a spawning inducer for fishes. Plant extracts can also be used as it is a new technique which could be used in aquaculture. The basic aim of our study was to enhance the growth as well as to check the effect of the traditional herb Foeniculum vulgare on the reproductive performance of Poecilia reticulata. Methodology: Samples were collected from a local fish shop in Sargodha. Ethanolic extract of Foeniculum vulgare seeds was prepared and mixed with different commercial feed. This feed was given to fish for 90 days to test the effect of Foeniculum vulgare seed extract on growth and reproduction performance. Water quality parameters were also maintained and recorded daily. Fecundity and Gonad somatic index were measured after dissection by removing the ovaries. Fecundity was calculated by counting the number of larvae and eggs seen with the naked eye. The hatching rate was measured by counting the number of hatching in each spawning. Results: According to the growth results, different levels of fennel seed extract has a significant effect on weight gain, length gain and survival rates of the fish in different groups. Statistical analysis cleared that T2 showed the highest weight and length gain. The feed Conversion Ratio decreased significantly. Results of reproduction parameters showed that the highest absolute fecundity (9.4 ± 0.19), GSI (8.69 ± 0.2) and spawning have increased in T2 followed by T1, T3, and control respectively. The observation of present research shows that Foeniculum vulgare seed extract can act as an estrogenic compound and growth promoter in commercial aquaculture.
自然养殖的鱼不能满足人类的需求。因此,诱导育种是满足这一需求的必要条件。诱导育种可确保及时供应具有所需特性的鱼类种子,为此可使用不同的技术。从这个角度来看,合成激素,垂体激素提取物,促性腺激素释放激素,有时人类慢性促性腺激素被用作鱼类的产卵诱导剂。植物提取物是一种可用于水产养殖的新技术。本研究的基本目的是促进网纹雌蜂的生长,并考察传统中药小茴香对网纹雌蜂生殖性能的影响。方法:样本采集自萨戈达当地一家鱼店。制备了小茴香种子的乙醇提取物,并与不同的商品饲料混合。将该饲料投喂鱼90 d,以测试小茴香种子提取物对鱼生长和繁殖性能的影响。每天也保持和记录水质参数。切除卵巢后测定生殖力和性腺体细胞指数。通过肉眼看到的幼虫和卵的数量来计算繁殖力。通过计算每次产卵中孵化的数量来衡量孵化率。 结果:从生长结果来看,不同水平的茴香籽提取物对不同组鱼的增重、增长和成活率均有显著影响。统计分析表明,T2的体重和长度增加最多。饲料系数显著降低。繁殖参数结果表明,T2的绝对繁殖力最高(9.4±0.19),GSI最高(8.69±0.2),产卵量依次升高,T1、T3和对照次之。本研究结果表明,小茴香种子提取物在商业水产养殖中具有雌激素化合物和生长促进剂的作用。

Aim: This research intends to evaluate the toxicity of latana camara and ascertain if it can be useful as a plant-based additive in the formulation of fish feed. Study Design: The study was conducted using two replicate (Batch A and B) for 96 hours under controlled laboratory conditions. Five concentrations ranging from 0, 5, 10, 15, and 20 mg/l were prepared from the ethanolic extract (EE) of L. camara for the toxicity test. Place and Duration of Study: Experiment was conducted in Akwa Ibom State University, Obio Akpa Campus, Akwa Ibom State between February, 2023 and June, 2023. Methodology: Total of two hundred (200) juveniles were collected for the studies. One hundred (100) juveniles were used during range findings test and the left over for the actual toxicity test. Prior to commencement of the toxicity test, experimental fish were allowed to acclimatize. Each of the ten (10) plastic aquaria was stocked with ten (10) O. niloticus juveniles. The prepared plant extract at varying concentration was added to each stock aquaria and allowed to stand for 96 hours for mortality examination. Gills tissues were isolated from the fish samples in each of the concentration after 96 hours for histopathological examinations. Results: The experimental animals showed differential percentage mortalities with toxicant concentrations. The 96 hours LC50 for O. niloticus for both batches (A and B) was given at 7.346 mg/l representing a log transformed concentration of 0.866 mg/l. The different batches of O. niloticus (P = .05) had no significant difference in mortality. The results of the present study suggest that the EE of L. camara had severe impacts on the test organism resulting in mortality. The effects of L. camara on the gills of O. niloticus Juveniles showed severe impacts on the test organisms. Five samples were taken from each of the concentrations to examine the effects of the extract on the gills of O. niloticus. There were no observed changes in the gills of the control group as compared to other treatment which showed evidence of histological alterations. Conclusion: From the findings, it is observed that extract obtained from L. camara is toxic to aquatic life and cannot be recommended as a plant-based additive in the formulation of fish feed.
目的:本研究旨在评价大头鱼的毒性,并确定其是否可作为一种植物性添加剂用于鱼饲料配方。研究设计:在受控的实验室条件下,采用两个重复(A批和B批)进行96小时的研究。以金针菇乙醇提取物(EE)为原料,分别制备0、5、10、15、20 mg/l 5种浓度进行毒性试验。 研究地点和时间:实验于2023年2月至2023年6月在阿夸伊博姆州阿夸伊博姆州Obio Akpa校区阿夸伊博姆州立大学进行。 方法:总共收集了200名青少年进行研究。一百(100)只幼鱼用于范围发现试验,剩下的用于实际毒性试验。在开始毒性试验之前,实验鱼被允许适应环境。每10个塑料水族箱里都放有10条尼罗ticus幼鱼。将制备好的不同浓度的植物提取物添加到每个砧木水族箱中,静置96小时进行死亡率检查。96小时后,从每种浓度的鱼样本中分离鳃组织进行组织病理学检查。 结果:不同浓度毒理学实验动物的死亡率不同。两个批次(A和B)的96小时LC50为7.346 mg/l,对数转化浓度为0.866 mg/l。不同批次的niloticus的死亡率差异无统计学意义(P = 0.05)。本研究结果表明,乳杆菌的EE对试验生物有严重的影响,导致死亡。camara对niloticus幼鱼鳃的影响显示出对试验生物的严重影响。从每种浓度中提取5个样本,以检查提取物对niloticus鳃的影响。与其他治疗组相比,对照组没有观察到鳃的变化,有组织学改变的证据。 结论:从研究结果中可以看出,从蓖麻中提取的提取物对水生生物有毒性,不能作为植物性添加剂推荐用于鱼类饲料配方中。
