Chromosome-level genome assembly and annotation of largemouth bronze gudgeon (Coreius guichenoti).

Coreius guichenoti, mainly distributed in upstream regions of the Yangtze River China, is currently on the brink of extinction and listed as national secondary protected animal. In this study, we aimed to obtain the chromosome-level genome of C. guichenoti using PacBio and Hi-C techniques.

Effect of Different Opening Diet on the Growth, the Structure of the Digestive Tract and Digestive Enzyme Activity of Larval and Juvenile .

One of the crucial factors influencing the growth and viability of larvae and juveniles is their opening diets. The objective of this study was to identify suitable initial feed options for larvae and juveniles. A total of 1200 newly hatched with an average weight of 18.

Initial Alterations of Fish Community Structure and Diversity Following Fishing Cessation in Qilu Lake, China.

The Qilu Lake is an eutrophic shallow lake located in Yunnan Province, China. An ecological fishery project was initiated in the lake from 2011 to 2021 to introduce filter-feeding fish species that feed on algae, with the aim of improving water quality. In January 2022, when the ecological fishery project expired, all fisheries-related activities (including fish stocking and fishing activities) ceased in the lake.

Initial Post-Release Performance of Cultured Juveniles in a Shallow Lake in Southwestern China.

The post-release performance of cultured fish is crucial for understanding the viability of cultured fish and assessing the effects of stock enhancement programs. This study aimed to investigate the initial post-release performance of cultured juveniles by examining their movement, spatial distribution, gut fullness, and gut microbiota in nature. In July 2022, a total of 20,000 juveniles, tagged with visible implant fluorescence (VIE), were released into Qilu Lake, a shallow lake in southwestern China.

Effects of water temperature on growth performance, digestive enzymes activities, and serum indices of juvenile Coreius guichenoti.

This study was conducted to determine the optimal temperature for Juvenile Coreius guichenoti, which is critically endangered in China. Test fish with an initial body weight range of 17.60-18.

Comparing diversity patterns and processes of microbial community assembly in water column and sediment in Lake Wuchang, China.

The study compare the diversity patterns and processes of microbial community assembly in the water and sediment of Lake Wuchang (China) using high-throughput sequencing of 16S rRNA gene amplicons. A higher microbial α-diversity in the sediment was revealed ( < 0.01), and the most common bacterial phyla in water column were Proteobacteria, Cyanobacteria and Actinobacteria, while Proteobacteria, Acidobacteria, Chloroflexi and Nitrospirae were dominant in sediment.

Temperature Acclimation Alters the Thermal Tolerance and Intestinal Heat Stress Response in a Tibetan Fish .

Numerous studies have shown that thermal tolerance and intestinal heat resistance are strongly associated with temperature acclimation. However, few reports have successfully conducted similar research on fishes from the Qinghai-Tibetan Plateau, an area that is facing the threat of climate warming. Therefore, the present study determined the growth, thermal tolerance, and intestinal heat stress (exposure to 30°C) responses in juveniles of a Tibetan fish, , acclimated to three temperature levels (10°C, 15°C, and 20°C, named as T10, T15, and T20, respectively) for 30 days.

Assessment of eutrophication and nitrogen and phosphorus carrying capacity before and after removing pen culture (2013-2018) in Lake Changhu, China.

In this study, the eutrophication levels and nitrogen and phosphorus carrying capacities of Lake Changhu in Jingzhou, Hubei Province, China, were measured using the trophic level index (TLI) and Dillon model for the first time. The measurements were taken before (2013 and 2015) and after (2017 and 2018) the removal of pen aquaculture from the lake. The lake was divided into three districts: Lake Haizihu, Mahongtai Channel, and Lake Dahu.

The total length of the mitogenome is 16,542 bp, including 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a control region.

The complete mitochondrial genome of the (Siluriformes：Sisoridae).

is an endemic fish species in the Lantsang River. In this study, the complete mitochondrial genome sequence of was determined and analyzed. The 16,432 bp long circular molecule consisted of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region, and all genes show the typical gene arrangement conforming to the vertebrate consensus.

Complete mitochondrial genome and phylogenetic analysis of (Cypriniformes: Cyprinidae).

Effects of growth hormone (GH) transgene and nutrition on growth and bone development in common carp.

Limited information is available on effects of growth hormone transgene and nutrition on growth and development of aquatic animals. Here, we present a study to test these effects with growth-enhanced transgenic common carp under two nutritional conditions or feeding rations (i.e.
