In this study, we compared the differences in metabolic enzymes and the mRNA expression of unfolded protein response (UPR)-related genes between the ammonia-resistant (LV-AT) and ammonia-sensitive (LV-AS) strains of Penaeus vannamei, aiming to investigate the different tolerance mechanisms of the two extreme strains underlying ammonia stress. The results showed that elevated ammonia concentrations mainly increased glutamine synthetase (GS) content while inhibiting transglutaminase (TG) content in the muscle of both strains and the contents were significantly higher in LV-AT than in LV-AS after 48 h of ammonia stress (). As a protective or adaptive strategy, the expression of the UPR related genes, including activating transcription factors ATF6, ATF4, and the spliced form of X box binding protein 1 (XBP1) were, respectively, either significantly induced, or inhibited () after ammonia stress. The mRNA expressions of the GRP78 (Bip) gene and the apoptosis gene (caspase 3) are then activated. In hepatopancreas and gills, the associated gene expressions gradually increase in LV-AT, while several related genes in LV-AS were first induced and then gradually inhibited. The expressions of key genes (GRP78, ATF6, XBP1 and ATF4) were significantly higher in LV-AT than that in LV-AS after 48 h of ammonia stress (). These results indicate that some enzymes involved in ammonia metabolism and UPR protection genes tended to be highly expressed in LV-AT. Hence, we speculate that LV-AT has a higher ammonia excretion capacity and a more effective adaptive mechanism after ammonia stress. The experimental results will help to further understand the stress response of P. vannamei to ammonia and provide a new perspective for the underlying molecular mechanism of the ammonia adaptation strategy of at least some strains of P. vannamei.","PeriodicalId":10834,"journal":{"name":"Crustaceana","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43541806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little information about the lengths and weights of their copepodids is available. In this study, we collected five sympatric aetideid copepods, Chiridius obtusifrons Sars G.O., 1902, Gaetanus tenuispinus (Sars G.O., 1900), Gaetanus brevispinus (Sars G.O., 1900), Aetideopsis multiserrata (Wolfenden, 1904), and Aetideopsis rostrata Sars G.O., 1903, from the Arctic Ocean and examined their body lengths, dry and ash-free dry weights, and developmental growths at each copepodid stage. Highly significant length-weight relationships were obtained among copepodids for all species. Within genera, individuals of the same length were heavier at shallower depths. This may result from the greater nutritional availability to species within genera inhabiting shallower depths. Common to all species, the organic content (ash-free dry weight per dry weight) was high for the early copepodid stages. This may be due to the residual organic content of lipid-rich eggs retained in the non-feeding nauplii. The largest growth in females occurred at C5/C6, whereas the largest growth in males occurred at C4/C5, as determined by moult increment and proportion of growth in weight. These sex differences in weight growth could be due to the degeneration of the feeding appendage and cessation of feeding in C6 males of aetideid copepods.","PeriodicalId":10834,"journal":{"name":"Crustaceana","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43344234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Juvenile Chinese mitten crabs, Eriocheir sinensis, are considered to live in fresh water during their complex life history, whilst some are found in coastal wetlands. To understand how juveniles disperse in estuarine residence, we investigated their survival, feed intake and salinity preference after acclimating in three different water situations (i.e., fresh water, salt water and alternation between fresh water and salt water). We supposed that behavioural alternation and salinity preference would play an essential role in their acclimation. Results showed no significant difference in survival and feed intake amongst the three groups of juveniles () in acclimation trials. However, the feed intake of crabs in each group was declining after changing water every three days. In the salinity preference experiment, crabs from fresh water preferred 0 and 12, whereas those from salinity and alternation treatments showed no preference. The salinity preference seemed to be modified by prior acclimation as well, and juvenile crabs could therefore survive and disperse in the different salinities. Our study helps to explain the complex distribution of juveniles in estuaries and provides arguments for the feasibility of Chinese mitten crabs being reared in low salinity waters.","PeriodicalId":10834,"journal":{"name":"Crustaceana","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46695284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tissue distribution showed that β-catenin was highly expressed in ovary, testis, hepatopancreas, heart, and gills. During embryonic development, the transcript of β-catenin was relatively high in the zygote, and the thirty-two-cell stage, blastula stage, gastrula stage, and nauplius stage. The transcripts of β-catenin in haemocytes, gills, and hepatopancreas were significantly up-regulated after infection with Vibrio anguillarum Bergeman, 1909.
