One of the primary challenges in the catfish cultivation industry is the uncertainty (mostly due to weather conditions, natural feed availability, pests and diseases), limited availability, and often poor quality of catfish frys. Fry quality is crucial in aquaculture, yet its reliability is hampered by the natural spawning process, which is influenced by seasonal variations. To address this issue, artificial spawning techniques offer a viable solution. This activity aims to comprehend and effectively execute the precise methods of artificial spawning for catfish, ultimately striving for the production of high-quality fingerlings. Data collection involved the acquirement of both primary and secondary data. The artificial spawning process encompasses container and medium preparation, meticulous broodstock selection and breeding, the artificial spawning procedure, larval rearing, and nursery management. Results from the artificial spawning efforts revealed a fecundity of 75,000 individuals, a remarkable 90% fertilization rate, an 89% hatching success, and an impressive 90% survival rate. Notably, catfish fingerlings were found to harbor parasites such as Gyrodactylus sp., Trichodina sp., and Dactylogyrus sp. This occurrence can be attributed to the high population density of fish, which contributes to a decline in water quality, emphasizing the importance of cautious management practices in aquaculture.
鲶鱼养殖业面临的主要挑战之一是鲶鱼鱼苗的不确定性(主要是由于天气条件、天然饲料供应、病虫害)、有限的可用性以及通常较差的质量。鱼苗质量在水产养殖中至关重要,但其可靠性受到自然产卵过程的影响,而自然产卵过程又受季节变化的影响。为解决这一问题,人工催产技术提供了一个可行的解决方案。这项活动旨在了解并有效执行鲶鱼人工催产的精确方法,最终努力生产出高质量的鱼苗。数据收集涉及原始数据和二手数据的获取。人工催产过程包括容器和培养基准备、精心挑选和培育鱼种、人工催产程序、幼体饲养和育苗管理。人工催产的结果表明,受精率为 90%,孵化成功率为 89%,成活率为 90%。值得注意的是,在鲶鱼幼苗中发现了寄生虫,如天牛(Gyrodactylus sp.)、毛滴虫(Trichodina sp.

Mangrove forest in the Niger Delta and its associated biotic and abiotic has been greatly impacted by several factors, some natural and others anthropogenic in nature.  Anthropogenic activities have negatively affected the organisms that inhabit the forest resulting in the decrease in size of population of fiddler crabs (Uca tangeri). To investigate the influence of anthropogenic activities on the mangrove habitat, burrow distribution and population of fiddler crabs and soil physico-chemistry were determined in forested and deforested sites. Burrows and number of crabs outside burrows were counted while samples of soil were retrieved and moved to the laboratory for the determination of cadmium (Cd), lead (Pb), total hydrocarbon content (THC) and Zinc (Zn) using atomic absorption spectrophotometer. The conclusions show a lack of significant difference in burrow distribution between forested and deforested areas (P>0.05). Contrastingly there is significance in the difference in crab population in forested and deforested sites. (P<0.05), which showed that there were more crabs in deforested areas than forested areas. There was also a significant difference in chemical and microbial population (P<0.05).  There was higher THC in deforested areas, which was probably impacted by the heavy-duty vehicles used to cut down the trees. The result implies that human activities of deforestation and pollution influence crab population and soil physicochemistry in mangrove forest.
尼日尔三角洲的红树林及其相关的生物和非生物受到多种因素的严重影响,有些是自然因素,有些则是人为因素。 人为活动对栖息在森林中的生物造成了负面影响,导致大闸蟹(Uca tangeri)数量减少。为了研究人为活动对红树林栖息地的影响,研究人员在森林覆盖区和森林砍伐区测定了大闸蟹的洞穴分布和数量以及土壤理化性质。对洞穴和洞穴外的大闸蟹数量进行了计数,同时采集了土壤样本,并将样本移至实验室,使用原子吸收分光光度计测定镉(Cd)、铅(Pb)、碳氢化合物总含量(THC)和锌(Zn)。结论显示,森林覆盖区和森林砍伐区的洞穴分布差异不大(P>0.05)。相反,森林覆盖区和森林砍伐区的螃蟹数量差异显著。(P<0.05),表明森林砍伐区的螃蟹数量多于森林砍伐区。化学和微生物数量的差异也很明显(P<0.05)。 毁林地区的四氢大麻酚含量较高,这可能是受用于砍伐树木的重型车辆的影响。结果表明,砍伐森林和污染等人类活动会影响红树林中螃蟹的数量和土壤理化性质。

Leaf litter and subsoil arthropods are biotic factors of an ecosystem that play a significant role in nutrient cycling between soil and vegetation. The present study aimed to explore the abundance and diversity of leaf litter and subsoil arthropods in four different sites of three agroecological zones of the Northwest part of Bangladesh. A total of 1920 individuals belonging to 17 orders, 28 families and 34 species were found in the present study where 1099 individuals (14 orders, 23 families, 28 species) from Rajshahi University Campus (Site A), 259 individuals (6 orders, 7 families, 8 species) from Rajshahi Fruit Research Center (Site B), 354 individuals (7orders, 13 families, 13 species) from Kakon Hat Municipality (Site C) and 208 individuals (5 orders, 10 families, 10 species) from Chalan Beel (Site D) were collected during the period from November 2021 to October 2022. In this study, within the three agroecological zones, the highest number of individuals was recorded in Site A (n=1099, 57.24%) and the lowest number in Site D (n=208, 10.83%). Among 17 orders Coleoptera (624, 32.50%) was the first dominant order, Hymenoptera (414, 21.56%) was the second largest order, followed by Araneae (202, 10.52%) and the least dominant order was Metastigmata (8, 0.42%). Formicidae was the most dominant family among collected 28 families, sharing 376 individuals of the total captured individuals and Staphylinidae, sharing 198 individuals, was the second largest family, whereas Tenebrionidae (n=8), Psychodidae (n=8), and Laelapidae (n=8) were the minor dominant families in this study. Among the total of 34 species, Lasioderma sp. was the most dominant species, sharing 189 individuals with 9.84% of the total collected individuals whereas Alphitobius sp., Psychoda sp., and Hypoaspis sp. were least dominant species, and each species of these three comprised of only 8 members. In this study, 15 species were very common, 5 were common, 7 were fairly common, and 7 were rare. The values of Shannon diversity index (H'), Simpson’s diversity index (I-D), Margalef diversity index (DMg), Menhinick Richness index (DMn), Berger Parker dominance index (d) and Pielou’s evenness index (J') were 3.22, 0.95, 4.37, 0.78, 0.10, respectively. The study was the first attempt to examine the abundance and diversity of leaf litter and subsoil arthropods in four different sites of three agroecological zones in the northwest part of Bangladesh. Further study may be necessary for molecular identification of these species.
落叶层和土壤下节肢动物是生态系统中的生物因素,在土壤和植被之间的养分循环中发挥着重要作用。本研究旨在探讨孟加拉国西北部三个农业生态区的四个不同地点的落叶和土壤下节肢动物的丰度和多样性。本研究共发现了隶属于 17 目 28 科 34 种的 1920 个个体,其中拉杰沙希大学校园(地点 A)有 1099 个个体(14 目 23 科 28 种),拉杰沙希有 259 个个体(6 目 7 科 8 种)、在 2021 年 11 月至 2022 年 10 月期间,分别从拉杰沙希水果研究中心(地点 B)、卡孔哈特市(地点 C)和查兰海湾(地点 D)采集到 354 个个体(7 目、13 科、13 种)和 208 个个体(5 目、10 科、10 种)。在本次研究中,在三个农业生态区中,地点 A 的个体数量最多(n=1099,57.24%),地点 D 的个体数量最少(n=208,10.83%)。在 17 个目中,鞘翅目(624 个,32.50%)是第一优势目,膜翅目(414 个,21.56%)是第二大优势目,其次是鹤形目(202 个,10.52%),最低优势目是变态目(8 个,0.42%)。在收集到的 28 个科中,甲虫科(Formicidae)是最主要的科,占总捕获量的 376 个个体;葡萄孢科(Staphylinidae)占 198 个个体,是第二大科;而天牛科(Tenebrionidae)(8 个)、灵猫科(Psychodidae)(8 个)和莱拉皮科(Laelapidae)(8 个)是本研究中次要的主要科。在总共 34 个物种中,Lasioderma sp.是最主要的物种,共有 189 个个体,占总采集个体的 9.84%,而 Alphitobius sp.、Psychoda sp.和 Hypoaspis sp.则是最不主要的物种,这三个物种中每个物种都只有 8 个个体。在本研究中,15 个物种非常常见,5 个物种常见,7 个物种相当常见,7 个物种罕见。香农多样性指数(H')、辛普森多样性指数(I-D)、Margalef 多样性指数(DMg)、Menhinick 丰富度指数(DMn)、Berger Parker 优势指数(d)和 Pielou 均匀度指数(J')的值分别为 3.22、0.95、4.37、0.78、0.10。该研究首次尝试对孟加拉国西北部三个农业生态区四个不同地点的叶丛和底土节肢动物的丰度和多样性进行研究。进一步的研究可能对这些物种的分子鉴定很有必要。

Aims: This paper presents a comprehensive study of the Anuran fauna of Khyber Pakhtunkhwa, Pakistan, which was conducted across nine districts.  After the collection and identification of specimens from the study area, their diversity, relative abundance (RA), and distribution (C) were evaluated to understand their distribution patterns within Khyber Pakhtunkhwa. Place and Duration of Study: Anurans were collected from the districts of Peshawar, Dir, Bannu, Buner, Charsadda, Chitral, Karak, Lakki Marwat, and Haripur of Khyber Pakhtunkhwa from July to September 2021 and from April to June 2022. Study Design: Visual encounter surveys were conducted during different seasons, encompassing both daytime and nighttime observations near various water bodies such as water channels, small pools, and microhabitats suitable for the anurans. Emphasis was placed on the collection of specimens from diverse habitats. The collected specimens underwent thorough morphological and morphometric analyses to accurately identify the species. Methodology: In total, 190 specimens were collected and transported to the laboratory for identification. The collected specimens were euthanized, carefully arranged, and preserved in glass jars filled with a 10% formalin solution. Accurate species identification was achieved through the utilization of authentic literature, updated taxonomic keys, and observation and measurement of morphological and morphometric parameters. Results: The specimens that were examined and identified belonged to two families, Bufonidae and Dicroglossidae, and five genera. Two genera were observed in the Bufonidae family, Duttaphrynus and Bufotes. The Dicroglossidae family comprised three genera: Hoplobatrachus, Euphlyctis, and Allopaa. In the current study, seven different species were identified: Duttaphrynus stomaticus, Duttaphrynus melanostictus, Bufotes surdus from the Bufonidae family, and Hoplobatrachus tigerinus, Euphlyctis cyanophlyctis, Euphlyctis kalasgramensis, and Allopaa hazarensis from the Dicroglossidae family. Duttaphrynus stomaticus was the most abundant species found at all the study sites (C=88.8% and RA=44.2%), whereas Euphlyctis kalasgramensis and Allopaa hazarensis were sporadic (C=11.1% and RA=0.52%), and (C=11.1% and RA=2.10%), respectively. Furthermore, this research unveils the first-ever report of Euphlyctis kalasgramensis within Khyber Pakhtunkhwa, specifically in the Peshawar District, while Allopaa hazarensis was solely reported in the Dir district. Conclusion: The study found that Duttaphrynus stomaticus exhibited a vast distribution across all nine districts surveyed.  Khyber Pakhtunkhwa, being an ecologically diverse area, holds diverse anuran fauna. Taxonomic revision of the anuran fauna using both classical and molecular approaches may yield several new taxa. This will further help in the study of biology and conservation as well as the ecological role of anurans. The current taxonomic work may require improvement
目的:本文介绍了对巴基斯坦开伯尔-普赫图赫瓦省九个地区的阿努兰动物群的全面研究。在研究区采集鉴定标本后,对其多样性、相对丰度(RA)和分布(C)进行了评价,以了解其在开伯尔-普赫图赫瓦省的分布格局。研究地点和时间:于2021年7月至9月和2022年4月至6月从开伯尔-普赫图赫瓦省的白沙瓦、迪尔、班努、布内尔、查尔萨达、吉德拉尔、卡拉克、拉基马尔瓦特和哈里普尔地区收集Anurans。研究设计:在不同的季节进行视觉接触调查,包括白天和夜间在各种水体(如水道、小水池和适合无尾蜥蜴的微栖息地)附近进行观察。重点是收集来自不同栖息地的标本。收集的标本进行了彻底的形态学和形态计量学分析,以准确地识别物种。方法:共收集190份标本并送往实验室进行鉴定。收集的标本被安乐死,仔细排列,保存在充满10%福尔马林溶液的玻璃罐中。利用真实的文献资料、更新的分类关键字以及形态学和形态计量学参数的观察和测量,实现了准确的物种鉴定。结果:经检验鉴定的标本分属蟾蜍科和双虻科2科5属。在蟾科共发现2属,分别为Duttaphrynus和Bufotes。双舌蝇科包括三属:Hoplobatrachus, Euphlyctis和Allopaa。本研究共鉴定出7个不同的物种,分别是来自Bufonidae科的Duttaphrynus stomaticus、Duttaphrynus melanotictus、Bufotes surdus,以及来自Dicroglossidae科的Hoplobatrachus tigerinus、Euphlyctis cyanophlyctis、Euphlyctis kalasgramensis和Allopaa hazarensis。在所有研究点,Duttaphrynus stomaticus数量最多(C=88.8%, RA=44.2%), Euphlyctis kalasgramensis零星分布(C=11.1%, RA=0.52%), Allopaa hazarensis零星分布(C=11.1%, RA=2.10%)。此外,这项研究揭示了开伯尔-普赫图赫瓦省(特别是白沙瓦地区)首次报告的Euphlyctis kalasgramensis,而Allopaa hazarensis仅在Dir地区报告。结论:研究发现,Duttaphrynus stomaticus在调查的9个地区分布广泛。开伯尔-普赫图赫瓦省是一个生态多样化的地区,拥有各种各样的动物。利用经典方法和分子方法对无尾龙动物群进行分类修订可能产生几个新的分类群。这将进一步有助于研究无尾动物的生物学和保护以及生态作用。目前的分类学工作可能需要改进。

The main objective of the study is to estimate the NPK produced in the waste disposable of a Face Mask (FM) is decomposed with a medicinal plant Lagerstroemia speciosa (LS). The experimental design consists of 5 groups; each group contains yard soil, cow dung, and coir pith as compost bedding materials. T1 - control, T2 - KWCO, T3 - FMCO, T4 - LSCO and T5 - ESLS. The result shows that the growth rate of Eisenia fetida depends on the length and weight of worms. The reproduction rate varies depending on compost materials, with higher rates in T4 and lower rates in T1. The T5 shows a high level but is a little lower than the T4. Juvenile numbers are low in T2 and T3 trials. NPK Level: The nitrogen level 413.2±2.90** is highest in T4 and T3 is 404.3±1.78. Low in T1 336.6±2.84 trial, moderate in 376.3±3.13** T2 trial and T5 consist of 372.3±2.59**. The Phosphorus is commendably high in T5 1011.3±2.59** and T1 contains 992.3±3.06.  The moderate amount is in T4 894.3±2.22**. The lowest level of P 623±2.94** is in T2 and T3 contain 676.6±2.88**. The potassium amount is varying in each trial. T1 is the most prominent amount of Potassium, and the level of K is 1900.3±1.18. The kitchen waste T2 trial produced 1840.6±2.37** and the amount of K is in 1670.3±1.18** T4. The most important face mask blue and black colour samples is mixed with kitchen waste T3 produces 1700±3.77** and medicinal Plant T5 which produces 1569.3±2.84**. Our conclusion is that the medicinal plants had a significant effect on the growth and reproductive rate of red wrigglers, and this effect was positively correlated with the NPK level in the soil.

Heavy metal assessment in Sediments from Qua Iboe River Estuary, South-South, Nigeria was steered between January, 2022 and December, 2022 with the goal of understanding the route sources of heavy metal concentration within the system. Sediment samples were collected monthly from five stations taking cognizance of areas with high, medium and low human activities along the estuary. The samples collected were analyzed using standard protocol as recommended by APHA. Sediments mean values for wet and dry seasons observe were: Cadmium (0.20±0.04 and 0.19±0.04 mg/kg), Chromium (0.35±0.07 and 0.28±0.05 mg/kg), Copper (0.97±0.15and 10.94±0.14 mg/kg), Iron (130.79±13.69 and 115.29±10.19 mg/kg), Lead (0.56±0.06 and 0.54±0.06 mg/kg), Zinc (19.36±2.24 and 18.71±2.78 mg/kg). Heavy metal concentrations in sediments were below the DPR target / intervention limits with exception of iron without a standard. Analysis of variance and paired sample t-test revealed significant (p = 0.05) spatial variation but no seasonal variations were observed respectively. Values of trace metal recorded in the sediment throughout the study duration when compared to DPR target / intervention limit were below the threshold level as recommended. This suggest minimal anthropogenic activities during the period of studies. Nevertheless, constant monitoring of water bodies at regular interval is strongly recommended.
在2022年1月至2022年12月期间,对尼日利亚南南Qua Iboe河口沉积物中的重金属进行了评估,目的是了解系统内重金属浓度的路径来源。根据河口沿岸人类活动高、中、低的区域,每月采集5个站点的沉积物样本。采集的样品采用APHA推荐的标准方案进行分析。湿季和旱季沉积物平均值分别为:镉(0.20±0.04和0.19±0.04 mg/kg)、铬(0.35±0.07和0.28±0.05 mg/kg)、铜(0.97±0.15和10.94±0.14 mg/kg)、铁(130.79±13.69和115.29±10.19 mg/kg)、铅(0.56±0.06和0.54±0.06 mg/kg)、锌(19.36±2.24和18.71±2.78 mg/kg)。沉积物中的重金属浓度低于DPR目标/干预限度,但铁没有标准。方差分析和配对样本t检验显示空间差异显著(p = 0.05),无季节差异。在整个研究期间,沉积物中记录的微量金属值与DPR目标/干预限值相比低于建议的阈值水平。这表明在研究期间人类活动极少。然而,强烈建议定期对水体进行持续监测。

Bandung Regency, known for its abundant fishery resources, has emerged as a key player in this sector. Among the various fishery commodities, freshwater crayfish has gained popularity due to its market advantages and ease of cultivation. The development of crayfish cultivation in Bandung Regency offers an excellent opportunity for local farmers and investors, leveraging the region's abundant resources. Initially favoured as a consumable commodity, crayfish has now gained traction as an ornamental fish. Its higher profitability, shorter maintenance time, lower risks, and increased profits have contributed to its attractiveness as an ornamental fish commodity. This paper presents a case study on the development of freshwater crayfish cultivation in Cangkuang District, Bandung Regency, West Java, Indonesia, aiming to enhance the income of ornamental fish cultivators by maximizing cultivation productivity. Furthermore, Bandung Regency stands out as a promising area for aquaculture development, boasting vast public waters and a thriving fishery sector. Ornamental fish cultivation plays a significant role, with local farmers producing various species, including koi, comet goldfish, flowerhorn, and crayfish. To optimize crayfish cultivation, this study provides insights into culture techniques, including site selection, cultivation containers (such as ponds and aquariums), water quality management, feeding practices, parent selection, brood care, spawning processes, larvae rearing, and market analysis. By implementing these techniques, the cultivation of freshwater crayfish can flourish in Bandung Regency, contributing to the economic growth and income generation in the region.

A Review on Herb Utilization in Vannamei Shrimp Cultivation 凡纳美对虾养殖中草药利用研究进展
Pub Date : 2023-07-17 DOI: 10.9734/ajriz/2023/v6i4117

Aquaculture activities play a crucial role in boosting fishery production. Among the various commodities, Vannamei shrimp (Litopenaeus vannamei) stands out as a leading choice due to its competitive pricing and the ability to conduct mass production with high stocking densities. However, shrimp farming has encountered challenges, particularly the occurrence of diseases that often lead to reduced production levels. These diseases typically arise from the shrimp's weakened condition and suboptimal rearing conditions. To address this issue, incorporating several herbal plants, such as noni fruit, ginger, and garlic, into the feed has emerged as an alternative to enhance shrimp immunity. Through an extensive literature search, optimal doses for these herbal additives were identified. Noni fruit demonstrated the best performance at a 6% dose, resulting in a feed conversion ratio (FCR) of 1.1 and a survival rate of 95%. Garlic performed well at a 5% dose, achieving an FCR of 1 and a survival rate of 98%. Similarly, ginger showed promising results at a 3% dose, with an FCR of 1.18 and a survival rate of 98%. The findings of this study emphasize that incorporating herbs into the feed can serve as a viable solution to enhance productivity in Vannamei shrimp farming.
水产养殖活动在促进渔业生产方面发挥着关键作用。在各种商品中,凡纳美对虾(凡纳美对虾)因其具有竞争力的价格和以高放养密度进行大规模生产的能力而成为主要选择。然而,对虾养殖遇到了挑战,特别是疾病的发生往往导致生产水平下降。这些疾病通常是由虾的虚弱状况和不理想的饲养条件引起的。为了解决这个问题,在饲料中加入一些草药植物,如诺丽果、生姜和大蒜,作为提高虾免疫力的替代方案已经出现。通过广泛的文献检索,确定了这些草药添加剂的最佳剂量。诺丽果在添加6%剂量时表现最佳,饲料系数为1.1,成活率为95%。大蒜在5%剂量下表现良好,FCR为1,存活率为98%。同样,生姜在3%的剂量下显示出令人满意的结果,FCR为1.18,存活率为98%。本研究结果强调,在饲料中添加草药可以作为提高凡纳美对虾养殖生产力的可行解决方案。
