However, the molecular mechanism for gills of fish needs still to be explored. In the present study, transcriptomic analysis and identification of SSR and SNP markers were performed in the gills of crucian carp Carassius auratus. The results showed a total of 84,259 unigenes were annotated to NCBI NR, KEGG and GO databases for 55,283, 39,303, 33,388, respectively. Enriched KEGG pathway analyses for the identified genes showed the mainly functional modules such as metabolism, cellular processes, environmental adaptation, genetic processing, organismal and immune systems. Moreover, 22,102 SSRs (simple sequence repeats) were potentially identified and 9776 (44.2%) were accounted for the most dinucleotides. Transition and transversion sites of SNPs (single nucleotide polymorphisms) were also observed. Tissue distribution showed that the expression level of lysozyme LysC gene was relatively high in intestine, liver, spleen and kidney tissues and up-regulated in gills, skin and brain after the A. hydrophila infection. We discovered the immune-related pathways through the transcriptome analysis in the gills of crucian carp, some potential SSR/SNP markers were identified, and lysozyme gene predominantly expressed in mucosal immune organs (eg., gills, skin, intestine) responded to A. hydrophila infection. To the best of our knowledge, this was the detailed report on the molecular characteristics in crucian carp gills with transcriptome analysis, which will not only provide a scientific reference for further understanding the local defense mechanism, but also lay a foundation for molecular marker-assisted breeding in fish.","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134962148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyethylene aquaculture cage net surface which is modified with polyaniline and nano-copper oxide (CuO), reported to have biofouling resistance. Leaching of nano CuO from the net to the aquatic environment and its bioaccumulation in fish is the major concern against the technology adoption. The present study aimed to understand the accumulation of copper in fishes grown in a nano CuO treated aquaculture cage net. Studied the leaching pattern of nano CuO, biofouling inhibition and changes in strength of the cage net due to the nano CuO treatments. Fishes grown in the treated cages exhibited normal growth characteristics with no signs of abnormalities and also copper in their organs were within the prescribed standard limit. The CuO treated cage net exhibited excellent biofouling resistance and the percentage of occlusion of mesh by foulers were 56.77% more efficient than untreated cage net. Rate of nano CuO leached to the aquatic system was less than 8 μg/g·d. The fouling organism assemblage on untreated and treated net was 18 and 11 species, respectively. Major calcareous shelled foulers were absent on treated nets.

This is a severe limitation that prevents using the data for research on population dynamics, stock assessment, forecasting, and, hence, decision-making around marine resources. Several methods have been proposed to impute missing data in univariate time series. Still, their performances depend not only on the amount of missing data but also on the data structure. This study compares the performance of twelve imputation methods on the time series of marine fishery landings for six species in the Colombian Pacific Ocean. Unlike other studies, we validate the precision of the imputations in the same target time series that include missing data, using the Known Sub-Sequence Algorithm (KSSA), a novelty validation approach that simulates missing data in known sub-sequences of the target time series. The results showed that the best methods for imputation are Seasonal Decomposition with Kalman filters and Structural Models with Kalman filters fitted by maximum likelihood. Results also show that validating the imputation methods with other time series different to the target time series, leads to wrong imputation methods choices. It is noteworthy that these methods and also the validation framework are mainly suited to time series with non-random distribution of missing data, this is, missing data produced systematically in chunks or clusters with predictable frequency, which are common in marine sciences.</p></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"8 5","pages":"Pages 587-599"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49842018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sex determination in teleost fishes is governed via a complex regulatory network involving multiple genetic, environmental (temperature, population density, pH), social interaction/stress factors. Piscine germ-line originates as Primordial germ cells (PGC) from cleavage blastomeres/endoderm and gets specified by maternal inheritance of <em>Vasa, N</em>anos, <em>Tdrds, Dnd</em>, <em>Dazl</em> etc and subsequently migrates to reach the embryonic gonadal primordium. Post-hatching, mitotically active germ cells (Gc) continue to proliferate via two distinct pathways-firstly, stem cell-like mode followed by meiosis-committed cystic division. In Japanese rice fish medaka, <em>Oryzias latipes</em> sex gets determined on the chromosomal basis, where XY becomes a male because of testicular <em>Dmy</em> transcription and XX develops as female owing to Gc restricted <em>Foxl</em>_<em>3</em> expression. Sex specific germ-line stem cell systems also have been found in adult <em>O. latipes</em>. Intriguingly in teleost fishes, the developmental fate of transplanted Gc do not depend on the sex of the donor rather solely relies upon the sex of the recipient. Furthermore, sexually mature piscine gonads remain developmentally plastic showing extensive responsiveness towards sex steroids. The critical regulation of gonadal differentiation is directed by female specific 17β-estradiol (E₂) and bio-active male androgen 11-keto-testosretone (11-kT). Various transcription factors (TFs) e.g.- <em>Dmrt1, DAX1, Ad4BP/SF-1, Foxl</em>_<em>2</em> regulate the bio-conversion rate of testosterone (T) to either E₂ or 11-kT. Similarly, multiple endocrine factors (EFs) e.g.- LH, FSH, E₂, 11-kT and growth factors (GFs) e.g- AMH, GSDF, IGF-1/3, GDF-9/BMP-15 critically induce Gc differentiation to regulate the gametogenic output. In this article we have precisely discussed the endocrine regulation of Gc development during gonadal maturation of teleosts.</p></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"9 3","pages":"Pages 422-436"},"PeriodicalIF":0.0,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2468550X2300093X/pdfft?md5=4267c61295b3eeedfa288726075ba134&pid=1-s2.0-S2468550X2300093X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91391698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
