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.

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 <i>Narcine</i> spp. The slightly larger mitogenome length of <i>N. timlei</i> than other <i>Narcine</i> spp. may be due to the presence of a putative control region of 1,916 bp with three tandem repeats.

To investigate the potential biological markers between young males and females <i>S. asotus</i>, 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 (<i>GH-1</i>), growth hormone receptor gene (<i>GHR</i>), and insulin-like growth factor gene (<i>IGF-1</i>) 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 (<i>P</i> &lt; 0.05) or very significantly (<i>P</i> &lt; 0.01) different between juvenile males and females. The visceral weight, eviscerated weight, and intestine weight in females were significantly (<i>P</i> &lt; 0.05) or very significantly (<i>P</i> &lt; 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 contrast, the three genes were all more highly expressed in the testis than in the ovary (<i>P</i> &lt; 0.01), indicating their essential roles in testis development.

{"title":"How (not) to read fish genomics data – The importance of cytogenomics knowledge in the current flood of sequenced genomes","authors":"Radka Symonová","doi":"10.1111/jai.14365","DOIUrl":"10.1111/jai.14365","url":null,"abstract":"&lt;p&gt;Biologists have been facing a tremendous data explosion during the last years. This is particularly apparent in the still increasing amount of sequenced genomes. However, it is not always straightforward to understand and properly utilize these data that may be publicly available in an incomplete form. This is the case of the current flood of fish genomes among others. In reaction to this situation a recent study by Randhawa and Pawar (&lt;span&gt;2021&lt;/span&gt;) tried to exploit these data, however, in an improper way. This study is not the only one suffering from serious problems with handling genomic data and contextualizing them in organismal evolution. On the other hand (Randhawa &amp; Pawar, &lt;span&gt;2021&lt;/span&gt;) accumulated several serious issues in a single paper and further analysed their incorrect findings. This short communication aims to elucidate unclarities in that study and to provide some simple hints how to avoid similar issues. This is particularly relevant for fish genomics, where an immense biodiversity results in a so far unexplored diversity of genome traits.&lt;/p&gt;&lt;p&gt;The study by Randhawa and Pawar (&lt;span&gt;2021&lt;/span&gt;) is based on the NCBI repository of genomic data (Genome, &lt;span&gt;2022&lt;/span&gt;). Even such excellent and indispensable tools like NCBI/Genome are not absolutely flawless as they rely on data submitted by other scientists. Hence, it is crucial to always manually check all downloaded data. The best way is to sort the dataset according to e.g. genome size (GS) and according to GC content (GC%). Then, the incorrect values are immediately apparent on both of ends of the dataset upon these procedures. Namely, the incomplete genome assemblies result in too small genome sizes (e.g. &lt;i&gt;Squalius pyrenaicus&lt;/i&gt; with a fully non-sense genome size of 48 Mb reported by Randhawa &amp; Pawar, &lt;span&gt;2021&lt;/span&gt;). As a result, such incomplete assemblies can yield fully aberrant values of GC%, both extremely low (e.g. &lt;i&gt;Chionodraco hamatus&lt;/i&gt; with GC = 25.4%) or extremely high (e.g. &lt;i&gt;S. pyrenaicus&lt;/i&gt; with GC = 51.1%). Such values have to be, of course, discarded. A similar mistake was identified in the paper by Lu &amp; Luo, &lt;span&gt;2020&lt;/span&gt;, who presented the channel catfish to have GC = 31.5% and claimed this value as the lowest one within their dataset. In this particular case, it is apparent that this value is incorrect in their dataset and too low for a vertebrate genome. The value of GC% is crucial for several reasons and particularly regarding the genome completeness, since GC-rich regions were underrepresented from technical reasons in the earlier versions of genome assemblies (Rhie et al., &lt;span&gt;2021&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;A fully different however equally important issue is where to place the borderline between the incomplete and still usable but low(er) quality genome assemblies. This is crucial to be able to decide, which values are to be discarded and which retained. This issue cannot be easily solved because there is usually no gap ","PeriodicalId":14894,"journal":{"name":"Journal of Applied Ichthyology","volume":"2025 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jai.14365","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45253653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
