Poly-β-hydroxybutyrate (PHB) is a bacterial metabolite produced by bacteria such as sp. that serves as a carbon and energy storage compound for bacteria under nutrient-limited conditions. Two experiments were conducted to investigate the effects of dietary supplementation with -PHB on hybrid grouper ( ♀ × .

Though we have previously reported that Hsp70 knockdown may have little or no impact on Artemia development, the gestational survival and number of offspring released by adult females were impaired by obscuring Hsp70 synthesis. Transcriptomic analysis revealed that several cuticle and chitin synthetic genes were downregulated, and carbohydrate metabolic genes were differentially expressed in Hsp70-knockdown individuals.

As a result of climate warming and wetting, the areas of salt lakes on the plateau have been increasing, and the salinities have decreased considerably since 1990s. However, the impact of salinity change on the genetic diversity of Artemia is still unknown.

The nine endemic species of the genus from the Yarlung Zangbo River, Tibet comprise a putative cyprinid species flock. In this study, the effectiveness of the COI DNA barcode for Schizothoracinae species identification was verified by using 45 COI sequences covering nine species in four genera of Schizothoracinae fishes. The average Kimura two parameter (K2P) genetic distances within and among species were 0.

However, the reproductive patterns and its regulatory mechanisms in remain unclear. In this study, the ovarian development process of parthenogenetic () was divided into five stages, and oogenesis or egg formation was identified in six phases.

Brine shrimp (Artemia) has existed on Earth for 400 million years and has major ecological importance in hypersaline ecosystems. As a crucial live food in aquaculture, brine shrimp cysts have become one of the most important aquatic products traded worldwide. However, our understanding of the biodiversity, prevalence and global connectedness of viruses in brine shrimp is still very limited.

The bacterial storage compound poly-β-hydroxybutyrate (PHB) is a potential bio-control agent in aquaculture. It has been reported that PHB benefit to the survival and growth, and improve their immunity of aquatic animals. However, the cellular and molecular regulation mechanisms of PHB in immunity process remain unclear.

In the study, we report the complete mitochondrial genome of Piccinelli and Prosdocimi, 1968 for the first time. The mitochondrial genome of is 15,436 bp in length, with the typical structure of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and 2 ribosomal RNA genes, and a non-coding control region (CR). Phylogenetic analysis showed that was at the basal position among the bisexual species, which revealed that is likely to be an ancestral clade.

In the study, the complete mitochondrial genome of was reported for the first time. The mitochondrial genome of is 15,762 bp in length, with the typical structure of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and two ribosomal RNA genes, and a major non-coding region (CR). Phylogenetic analysis showed that has a much closer relationship with compared to other species.
