Fingerlings selected according to Nishikigoi pattern, either (9.66 ± 1.47) cm in standard length, from crossbred and pure carp, respectively, were cultivated in 8 cages (4 replicates for each genotype), measuring 9 m³ (3.0 m × 2.0 m × 1.5 m) each, in a 1500 m² (12 m × 125 m) pond at a depth of 1.60 m with 10 fingerlings/m³. Fish were fed four times a day at the rate of 5%–7% of biomass with the same specific diet for each growth stage. Forty carp of each genotype (10 fish/cage) were weighed at days 0, 60, 150, 270 and 330 of cultivation. They were weighed and measured for head length, standard length, body height and body width. The Gompertz model was fit for weight × age data for comparison of absolute and relative growth rate, weight and age at the inflection points. The crossbred genotype showed better survival, weight gain and feed conversion compared to pure carp (<em>P</em> &lt; 0.05). The final weight estimate at 330 days was 38.45% higher in the crossbred genotype (289.16 g) when compared to the pure carp (208.85 g). The pure genotype presented lower weight (431.60 g), age (559.71 days) and absolute growth rate (1.03 g/day) at the inflection points when compared to the crossbred genotype (587.69 g; 559.71 days and 1.46 g/day, respectively). Body morphometric relationships changed with fish growth, and this occurred differently, depending on carp genotype evaluated. From these results, it can be concluded that crossing Nishikigoi with Hungarian carp can be a strategy to improve desirable characteristics in koi.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 3","pages":"Pages 452-458"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139538253","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}

Despite its high altitude and harsh natural environment, it occupies a strategic position adjacent to northern Nepal, India, and Ladakh. As a crossroads connecting the Tibetan Plateau, Xinjiang Autonomous Region, Central Asia, and South Asia, it likely played an important role in early human migration. Archaeological studies in recent years have revealed that even before the establishment of the Tubo Dynasty in the seventh century, the Ngari region maintained extensive cultural connections with Kashmir, Nepal, Xinjiang, and other regions. Furthermore, its subsistence economy reflected strong interactions between Ngari and northern South Asia. Recent paleogenetic studies have demonstrated that the genetic components of the ancient population in the Ngari region originated from the southern part of the plateau, with multiple population expansions occurring from south to west. These studies have also confirmed that alongside cultural exchanges, the Ngari region began experiencing complex genetic interactions with ancient populations from neighboring Central and South Asia at least 2,300 years ago. In this review, we integrate findings from paleogenetics, archaeology, archaeobotany, and zooarchaeology in the Ngari region to systematically examine the genetic origins of the ancient western plateau population and analyze both intraregional cultural-genetic interactions within the Tibetan Plateau and those between Ngari populations and external groups. This synthesis provides important insights for understanding the complex relationships between ancient population movements and interactions in the western Tibetan Plateau, as well as the transformation patterns of regional archaeological cultures and subsistence economies.</p>","PeriodicalId":35536,"journal":{"name":"遗传","volume":"47 5","pages":"501-512"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048131","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}

The chocolate squid bait significantly reduced the number of crabs caught per pot by 13.99% and the weight of crabs caught per pot by 2.88 kg. Although the chocolate squid bait is cheaper, the decrease in catch rates could require increased effort to reach individual quotas, which could lead to longer or more frequent fishing trips and more traps being fished, increasing fuel consumption and habitat disruption, resulting in negative environmental impacts.

The results showed that the digestive system of <em>E</em>. <em>sinensis</em> mainly consisted of the esophagus, stomach (including cardia stomach and pyloric stomach), midgut, intestinal bulb, hindgut and hepatopancreas. In the cardia stomach, calcification of the cuticle into cuticular ossicles, chitin tooth, ridge, bristles and other structures were observed at different sites, which together form the \"Gastric mill\" for grinding food. The pyloric stomach contains special comb-like structures and rows of pectinate bristles, which are important components of the gland filter for filtering and sifting food. The wall of the digestive tract of <em>E. sinensis</em> consists of four layers: the mucosal layer, the submucosal layer, the muscular layer and the outer membrane, of which the surface of the mucosal layer of the esophagus and hindgut has a well-developed cuticle with rows of setae, and the submucosal layer has special mucus glands (esophageal glands or hindgut glands); the surface of the mucosal layer of the midgut has no cuticle and has dense microvillus. The intestinal bulb has the morphological characteristics of the transition from midgut to hindgut. The hepatopancreas consists of many hepatic tubules, and four types of cells are often seen in the hepatic tubules, including absorptive cells (R cells), vesicular cells (B cells), fibroblasts (F cells), and embryonic cells (E cells).

During primitive hematopoiesis, hematopoietic-related transcription factors and their cofactors interact to form a complex regulatory network that controls the process of primitive hematopoiesis. Among the bHLH transcription factor family, SCL and LYL1 are key factors in embryonic hematopoiesis. SCL is responsible for initiating primitive hematopoiesis, while LYL1, a paralog of SCL, compensates for the hematopoietic impact of SCL deficiency in adulthood. However, the role of LYL1 in primitive hematopoiesis remains unclear. This study, through analysis of zebrafish blood cell scRNA-seq data, discovered high expression of <i>CABZ01066694.1</i> in hematopoietic stem/progenitor cells. Sequence alignment revealed it as a short transcript of the <i>lyl1</i> gene. Subsequently, using 5'RACE and sequencing, the study confirmed the existence of both long (<i>lyl1f</i>) and short (<i>lyl1s</i>) transcripts of <i>lyl1</i> in zebrafish and humans, similar to mice. Further analysis of scRNA-seq and RNA-seq data from public databases showed that in zebrafish primitive hematopoietic cells, <i>lyl1</i> primarily transcribes <i>lyl1s.</i> Finally, using Morpholino technology to knock down <i>lyl1f</i> and <i>lyl1s</i> separately, it was found that knocking down <i>lyl1s</i> hindered the production of primitive myeloid progenitors and primitive granulocytes, whereas knocking down <i>lyl1f</i> promoted the production of primitive macrophages.

Tautog has been identified as a candidate species for marine aquaculture in the region. Unfortunately, previous grow out studies have documented slow growth, which is detrimental for aquaculture. However, these studies contrast with data from wild populations which indicate rapid growth in the first few years of life. It is theorized that these differences in growth could be due to available diets. In the wild, tautog primarily prey on mollusks and crustacean prey, while laboratory studies rely on commercial fishmeal-based diets. This study compared the growth and survival of juvenile tautog fed with chopped green crabs, commercial fish pellets and a hybrid diet consisting of both green crabs and pellets. Wild juvenile tautog were collected from local waters and cultivated in a recirculating aquaculture system for 250 days. Tautog fed the commercial pellet diet had a growth rate of 0.31 ± 0.11 mm/day, consistent with previous grow out studies. The average growth rate of tautog fed the green crab diet was 0.52 ± 0.13 mm/day, with a peak growth rate of 0.66 ± 0.07 mm/day. The hybrid diet was intermediate to the other treatments at an average growth rate of 0.46 ± 0.1 mm/day.
