Twenty-nine native freshwater fish species belonging to the four orders and eight families were collected from the Hongshui River, which belongs to the upper reaches of the Pearl River, to analyze their length-weight relationships (LWRs). Twenty-nine freshwater native fish were sourced using cages (0.2 m in height, 0.25 m in width, and 8 m in length, with a mesh size of 5 mm) and triple gillnets (20–40 m long, 1–3 m high, and mesh size, 2−3 cm) between December 2021 and July 2022. For each freshwater fish, the total length (TL) and weight were measured to the nearest 1.0 mm and 0.1 g. All LWR parameters of the twenty-nine species were statistically significant P < 0.001 . The length-weight relationships for the nine species were new to the FishBase and new maximum lengths were recorded for the twenty species. The LWR values provided for the first time will help to validate the accuracy and predictability of the Bayesian models for estimating the species-specific growth parameters of the data-poor species.
从珠江上游红水河采集了8科4目29种本地淡水鱼类,分析了它们的长重关系。29种淡水本地鱼类来源于网箱(0.2 高度m,0.25 宽m,8 长度为m,网眼尺寸为5 毫米)和三重刺网(20–40 m长,1-3 m高,网眼尺寸为2−3 cm)。对于每种淡水鱼,测量的总长度(TL)和重量精确到1.0 mm和0.1 g.29个种的LWR参数均具有统计学意义,P<0.001。这9个物种的长重关系是FishBase的新发现,20个物种的新最大长度也被记录下来。首次提供的LWR值将有助于验证贝叶斯模型的准确性和可预测性,用于估计数据贫乏物种的物种特异性生长参数。

This study used gas chromatograph-mass spectrometer (GC-MS) to determine three kinds of halogenated organic pollutants (HOPs) in the edible muscles of nine fish species in the Laibin section of the Hongshui River of Xijiang River in the Pearl River system. The results showed that the sum of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in fish muscle was 8.94∼43.32 ng/g ww, 1.22∼4.09 ng/g ww, and ND∼0.13 ng/g ww, respectively. Evaluation indicators include analysis of the composition of homologous compounds, residues in different diets and habitats, and estimated daily intake (EDI) calculations. The analysis of the composition characteristics of homologous compounds showed that endrin was the most dominant in OCPs; hexachlorobenzene was the most dominant in PCBs; and BDE 154 was the most dominant PBDEs. Calculations of the levels of the HOPs in fish of different diets and habitats showed that OCPs and PCBs had the highest residues in carnivorous fish, and PBDEs had the highest residues in herbivorous fish. The residual OCPs, PCBs, and PBDEs in demersal fishes were the most. The estimated daily intake (EDI) results showed that daily fish consumption in the Laibin section of the Hongshui River would not cause HOPs health risks to the local residents. However, there is still a need for continuous monitoring of HOPs to reduce pollutant emissions and prevent pollution conditions from arising.
本研究采用气相色谱-质谱联用技术(GC-MS)对珠江水系西江红水河来滨河段9种鱼类食用肌肉中3种卤化有机污染物(HOPs)进行了测定。结果表明,鱼类肌肉中有机氯农药(OCPs)、多氯联苯(PCBs)和多溴联苯醚(PBDEs)的总量分别为8.94 ~ 43.32 ng/g ww、1.22 ~ 4.09 ng/g ww和ND ~ 0.13 ng/g ww。评价指标包括分析同源化合物的组成、在不同饮食和生境中的残留以及估计每日摄入量(EDI)的计算。同源化合物的组成特征分析表明,在OCPs中endrin是最主要的;多氯联苯中以六氯苯居多;bde154是最主要的多溴二苯醚。通过对不同饵料和生境鱼类中啤酒花残留量的计算,发现肉食性鱼类中有机磷和多氯联苯残留量最高,草食性鱼类中多溴联苯残留量最高。在底栖鱼类中,OCPs、PCBs和PBDEs的残留量最多。估算日摄取量(EDI)结果表明,红水河来滨河段每日食用鱼类不会对当地居民造成hop健康风险。然而,仍需要持续监测水草,以减少污染物排放和防止产生污染情况。

The long rough dab (Hippoglossoides platessoides) is one of the most common bottom dwelling fish species in the Barents Sea with a limited commercial value, even though it is regularly caught as bycatch. Adult H. platessoides can be found in large numbers along the west coast of Svalbard, but nothing is known about the spawning area of this species or the distribution of their eggs and larvae within Svalbard fjords. Recent findings of H. platessoides eggs in Kongsfjorden indicate that a spawning population exists either within the fjord or on the west Spitsbergen shelf.
长而粗糙的dab(Hippoglossoides platessoides)是巴伦支海最常见的底层鱼类之一,尽管它经常被作为副渔获物捕获,但商业价值有限。在斯瓦尔巴群岛西海岸可以发现大量的成年H.platssoides,但对该物种的产卵区或其卵和幼虫在斯瓦尔巴德峡湾内的分布一无所知。最近在Kongsfjorden发现的H.platssoides卵表明,峡湾内或斯匹次卑尔根大陆架西部都存在产卵种群。

In this study, we report, for the first time, mitochondrial genome of Narcine timlei (Bloch & Schneider, 1801) and its phylogenetic relationships within the order Torpediniformes. Narcine timlei is a medium-sized ray that occurs in nearshore waters of the Indo-Pacific and is classified as “‘vulnerable” category on the IUCN Red List. The mitogenome is assembled from short Illumina reads (150 bp paired end reads). It is 17,964 bp long and includes 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. The gene order, size, and nucleotide composition are largely consistent with mitogenomic characteristics of previously reported other Narcine spp. The slightly larger mitogenome length of N. timlei than other Narcine spp. may be due to the presence of a putative control region of 1,916 bp with three tandem repeats. Phylogenetic reconstruction using concatenated PCGs (n = 13) of 9 Torpediniformes based on maximum likelihood and Bayesian inference analysis revealed identical topologies. The tree showed two main clades: one clade containing members of the family Narcinidae and the second sister clade consisting of the families Narkidae and Torpedinidae. Our result supports the monophyletic nature of Narcinidae based on mtDNA. The information obtained in this study will contribute to a better understanding of the population genetics, phylogenetic analysis, conservation, and evolutionary biology research of N. timlei.
在本研究中,我们首次报道了Narcine timlei的线粒体基因组(Bloch&Schneider,1801)及其在Torpediques目中的系统发育关系。timlei Narcine是一种中型鳐鱼,出现在印度洋-太平洋的近海水域,在国际自然保护联盟红色名录中被列为“易危”类别。有丝分裂基因组由Illumina短读数(150 bp配对末端读数)。现在是17964 bp长,包括13个蛋白质编码基因(PCG)、22个tRNA基因和2个rRNA基因。基因顺序、大小和核苷酸组成在很大程度上与先前报道的其他Narcine spp.的有丝分裂基因组特征一致。与其他Narcin spp.相比,N.timlei的有丝裂基因组长度略大。可能是由于存在1916的假定控制区 bp,具有三个串联重复序列。使用串联PCG的系统发育重建(n = 13) 基于最大似然和贝叶斯推理分析的9个Torpediques揭示了相同的拓扑结构。该树显示了两个主要分支:一个分支包含Narcinidae科的成员,另一个分支由Narkidae和Torpedidae科组成。我们的研究结果支持了基于线粒体DNA的Narcinidae的单系性质。本研究获得的信息将有助于更好地了解铁姆雷的种群遗传学、系统发育分析、保护和进化生物学研究。

Aquaculture has tremendous economic significance in distinguishing males and females in the juvenile Silurus asotus (Linnaeus, 1758) to obtain a female population with tremendous growth potential. To investigate the potential biological markers between young males and females S. asotus, we analyzed the characteristics of sexual dimorphism by measuring the 14 length traits and 9 weight indicators in an artificial insemination population at 3, 5, and 7 months. In addition, quantitative real-time PCR (qRT-PCR) was performed to determine the sexually dimorphic expression of the growth hormone-1 gene (GH-1), growth hormone receptor gene (GHR), and insulin-like growth factor gene (IGF-1) in the hypothalamus, pituitary, gonad, and liver, at 3, 5, and 7 months. The results showed that in morphology, except for eye diameter and the distance between the pelvic and anal fins in 3-month fish, all other morphological indicators were significantly ( P < 0.05 ) or very significantly ( P < 0.01 ) different between juvenile males and females. The visceral weight, eviscerated weight, and intestine weight in females were significantly ( P < 0.05 ) or very significantly ( P < 0.01 ) higher than in males at 5 and 7 months. Joint static allometric analyses on 14 length indicators relative to weight showed different sex growth patterns in 3-month, 5-month, and 7-month fish. In gene expression patterns, GH-1, IGF-1, and GHR were highly expressed in the pituitary, with higher levels in females ( P < 0.05 or P < 0.01 ). In contrast, the three genes were all more highly expressed in the testis than in the ovary ( P < 0.01 ), indicating their essential roles in testis development. Our results demonstrate that S. asotus has female-biased sexual dimorphism. The length traits related to head shapes could be the potential phenotype marker to distinguish females and males in 7-month juveniles.
水产养殖对于区分幼鱼Silurus asotus (Linnaeus, 1758)的雄性和雌性,获得具有巨大生长潜力的雌性种群具有巨大的经济意义。通过测定3、5、7月龄人工授精种群的14个长度性状和9个体重指标,分析了雌雄异型性特征,探讨了雌雄异型性的潜在生物学标记。此外,采用实时荧光定量PCR (qRT-PCR)检测生长激素-1基因(GH-1)、生长激素受体基因(GHR)和胰岛素样生长因子基因(IGF-1)在3、5和7个月时下丘脑、垂体、性腺和肝脏的两性二态表达。结果表明:3月龄幼鱼除眼径和盆鳍与肛鳍之间的距离外,其余形态学指标在雌雄幼鱼间均存在显著(P < 0.05)或极显著(P < 0.01)差异。5、7月龄时,雌性的内脏重、全膛重和肠道重显著或极显著高于雄性(P < 0.05)。关节静态异速生长分析显示,3月龄、5月龄和7月龄鱼的性别生长模式不同。在基因表达谱上,GH-1、IGF-1和GHR在垂体中高表达,且女性高表达(P < 0.05或P < 0.01)。相比之下,这3个基因在睾丸中的表达量均高于卵巢(P < 0.01),说明它们在睾丸发育中起重要作用。我们的研究结果表明,美洲鳄具有雌性偏倚的两性二态性。与头型相关的长度性状可能是7月龄幼鱼区分雌雄的潜在表型标记。

Morphometric characteristics, length-weight relationships (LWRs), and condition factors (K) were studied for five indigenous fish species belonging to five different families (Barilius barila Hamilton, Cirrhinus reba Hamilton, Chanda nama Hamilton, Mystus bleekeri Day, and Clupisoma garua Hamilton), from the River Ganga in Bihar, India. A total of 557 fish individuals were collected seasonally from September 2021 to August 2022 using a monofilament drift gill net and a conical trap net Khairel jal. In morphometric analysis, the highest degree of correlation was observed between the total length and the standard length for all species (except C. garua). The estimated exponent value b varies from 2.920 to 3.214, where the slopes of regression lines among the species have significant differences ( p < 0.0001 ). The b value indicated that three species (B. barila, C. nama, and C. garua) follow positive allometric growth, whereas M. bleekeri shows isometric growth and C. reba exhibits negative allometric growth. The condition factor value for these fishes ranged from 0.67 to 0.98, which indicated that the population of C. reba was robust compared to all other species ( p < 0.0001 ). A new maximum length (146.8 mm) was obtained for B. barila from India. The present study gives baseline biological information on five commercially important indigenous fish species found in the River Ganga, Bihar. As the population of these species has been dwindling in recent times, these data will be important for the conservation and sustainable utilization of these important species in the long run.
研究了来自印度比哈尔邦恒河的五种本地鱼类(Barilius barila Hamilton、Cirrhinus reba Hamilton,Chanda nama Hamilton和Mystus bleekeri Day以及Clupisoma garua Hamilton)的形态计量学特征、长重关系(LWR)和条件因子(K)。从2021年9月到2022年8月,使用单丝漂移刺网和锥形捕获网Khairel jal季节性收集了557条鱼。在形态计量分析中,所有物种(C.garua除外)的总长度和标准长度之间的相关性最高。估计的指数值b在2.920到3.214之间变化,其中物种之间的回归线斜率存在显著差异(p<0.0001)。b值表明,三个物种(b.barila、C.nama和C.garua)遵循正异速生长,而M.bleekeri表现出等距生长,C.reba表现出负异速生长。这些鱼类的条件因子值在0.67到0.98之间,这表明与所有其他物种相比,瑞巴的种群是稳健的(p<0.0001)。新的最大长度(146.8 mm)从印度获得B.barila。本研究提供了比哈尔邦恒河中发现的五种具有商业重要性的本土鱼类的基线生物信息。由于这些物种的数量近年来一直在减少,从长远来看,这些数据对这些重要物种的保护和可持续利用至关重要。

We present the length-weight relationships (LWRs) in 20 cryptobenthic reef fish species in the Gulf of California (Mexico). Nine of these species had no LWR records yet. However, the other species had LWRs based on in-formalin specimens collected more than 20 years ago. This conservation method has likely affected LWRs parameters. Our study showed higher estimations of the parameter a obtained on fresh specimens than in-formalin individuals. On the other hand, parameter b was not affected. Therefore, the biomass estimates using previous LWRs were strongly underestimated. Ergo, the similitude in parameter b between the two conservation methods highlights that the shape of the LWRs is conserved and did not change over the last 20 years. Finally, we compared the LWRs of shared species in the region’s two main types of shallow reefs, i.e., coral and rocky reefs. We found that the body fitness was not affected by reefs type, which means that both habitats seem to offer similar living conditions for shared species.
我们介绍了加利福尼亚湾(墨西哥)20种隐海底暗礁鱼类的长重关系。其中9个物种还没有LWR记录。然而,其他物种的LWR是基于20多年前收集的福尔马林标本。这种保护方法可能会影响LWR参数。我们的研究表明,在新鲜标本上获得的参数a的估计值高于福尔马林个体。另一方面,参数b没有受到影响。因此,使用以往LWR的生物量估计被严重低估。埃尔戈,两种守恒方法之间参数b的相似性突出表明,LWR的形状是守恒的,在过去20年中没有变化。最后,我们比较了该地区两种主要类型的浅层珊瑚礁(即珊瑚礁和岩礁)中共享物种的LWR。我们发现,珊瑚礁类型不影响身体健康,这意味着这两个栖息地似乎为共享物种提供了相似的生活条件。

Fish are cold blooded vertebrates’ identification on the bases of morphology is not more precise and required high taxonomic expertise therefore molecular identification is used as an alternative and more accurate technique for the identification of fishes. In the current investigation 39 fish specimens were collected from May 2021 to February 2022. With this aim, the recent study was conducted in the freshwaters of River Swat in Malakand Division, Khyber Pakhtunkhwa, Pakistan to explore the genetic diversity of genus Triplophysa. DNA was extracted and amplified using gene specific primers. The PCR products carefully were sequenced and Phylogenic analysis was performed using neighbor-joining, maximum likelihood through MEGA software. Nucleotide composition and genetic pairwise distance recommend that the calculated species of the subfamily Nemacheilinae are organically dissimilar. The River Swat is the study area and it is inhabited by three Triplophysa species, Triplophysa naziri, Triplophysa microps, and Triplophysa choprai. The evolutionary tree shows that these species are clearly separated. The mean of total length calculated in the three species of the genus Triplophysa such as 8.175 ± 0.198 cm for Triplophysa naziri, 10.14 ± 0.35 cm for Triplophysa microps, 11.052 ± 0.23 cm for Triplophysa choprai. This study provides a model for the improvement of identification in cryptic diversity and field of ichthyofauna.
鱼类是冷血脊椎动物,由于形态学鉴定不够精确,对分类技术要求较高,因此分子鉴定是鱼类鉴定的一种替代方法。在目前的调查中,从2021年5月到2022年2月收集了39个鱼类标本。为此,本研究在巴基斯坦开伯尔-普赫图赫瓦省马拉坎德地区的斯瓦特河淡水中进行了研究,探讨了Triplophysa属的遗传多样性。提取DNA并用基因特异性引物扩增。对PCR产物进行仔细测序,并通过MEGA软件使用邻居连接进行系统发育分析。核苷酸组成和遗传配对距离表明,计算出的Nemacheilinae亚科种在有机上是不同的。斯瓦特河为研究区,分布有三种三物理种:naziri三物理种、Triplophysa microps三物理种和choprai三物理种。进化树显示这些物种是明显分开的。3种植物的总长度平均值为:naziri Triplophysa(8.175±0.198 cm), microps Triplophysa(10.14±0.35 cm), choprai Triplophysa(11.052±0.23 cm)。本研究为改进鱼类区系的隐蔽多样性和鉴定领域提供了一个模型。
