Summary: Results from a series of experiments on black rockfish show that boldness is significantly positively correlated with aggressiveness, metabolic rate, and stressed locomotor activity, while negatively correlated with stressed opercular beat rate. Bold fish exhibit higher aggressiveness and metabolic rate, and lower stressed opercular beat rate, with no significant correlations with basal locomotor activity or basal cortisol level. These findings suggest that boldness can be used as a tool to predict fish aggressiveness and metabolic rate in aquaculture.

Summary: CXCL14 is a chemokine that is orthologous in mammals and fish, with cell-specific expression in the brain and ovary of black rockfish (Sebastes schlegelii). This study identified the expression pattern of CXCL14 in S. schlegelii for the first time.

Summary: The study identified SsCL-11 as a member of the collectin family in black rockfish, which plays an important role in pathogen recognition and resistance. SsCL-11 exhibits the highest expression in the liver and shows induced expression in immune-related tissues following infection. It also has binding abilities to various carbohydrates, PAMPs, and bacteria, and can agglutinate bacteria in the presence of Ca2+.

Summary: This study investigated the cryopreservation of black rockfish sperm by optimizing the cryodiluent and exploring the molecular mechanisms of cryoinjuries through transcriptome and methylome analysis. The results provided insights into improving the cryopreservation method of black rockfish by identifying key genes and pathways affected by cryopreservation.

Summary: In this study, the TNF alpha was characterized and its roles in the immune system of black rockfish during bacterial infections were explored. The results showed that Ss_TNF alpha was significantly up-regulated in the spleen and intestine after infections, while down-regulated in PBLs. The expression patterns of other inflammatory cytokines were also observed.

Summary: The study used species distribution models to investigate the impact of climate change on the habitat suitability of Sebastes schlegelii, showing that the ensemble model produced more accurate projections than individual models. Bottom temperature was found to be the most important factor determining the distribution range of S. schlegelii, with climate change predicted to lead to habitat reduction for the species.

Summary: In this study, the expression patterns of 24 FGF genes were identified and characterized in different tissues of embryonic and adult black rockfish specimens. Nine FGF genes were found to be essential for myoblast differentiation, muscle development, and recovery in juvenile black rockfish. Furthermore, multiple FGF genes showed sex-biased expression patterns during gonad development, with FGF1 gene promoting germ-cell proliferation and differentiation in the testes. These findings provide a systematic and functional characterization of FGF genes in the black rockfish and lay a foundation for future studies on FGF genes in other large teleost fishes.

Summary: The study investigated the effects of different types and amounts of enrichment on fish stress response. Results showed that the plant enrichment groups had significantly higher basal stress levels compared to the structure enrichment groups, while the no enrichment control group and low-amount enrichment groups had significantly higher basal stress levels compared to the other two enrichment amount groups. The high-amount enrichment groups had significantly higher peak cortisol levels after acute stress compared to the other three enrichment amount groups.

Summary: The research suggests that the aggression of black rockfish is influenced by pre-aggressive experiences, with losers showing lower winning rates and higher cortisol levels. However, fish that did not experience victory or defeat demonstrated similar behavior and physiology when encountering new opponents, indicating that social defeat may suppress aggressive behavior in black rockfish.

Summary: By using histology and RNA-seq, key pathways and genes involved in gonadal development and gamete maturation in black rockfish were characterized and differentially expressed genes were identified in testes and ovaries. The study provides comprehensive insight into black rockfish gonadal development, highlighting important pathways and genes for further reproductive physiology and molecular biology research in ovoviviparity teleosts.

Summary: This study investigated the sperm morphological and physiological characteristics of Sebastes schlegelii using electron microscopy, computer-assisted sperm analyzer, and histologic analysis, revealing that sperm had a mature structure and swam freely in the ovary fluid during copulation. The majority of sperm were found scattered in the ovary cavity at the early storage stage, forming crypts for sperm storage until fertilization.

Summary: The study investigated the biotransformation and tissue distribution of methylated phenanthrenes in black rockfish, and identified these compounds as potential biomarkers of rockfish exposure to petrogenic PAHs that can be effectively eliminated from the fish's body.

Summary: This study identified 14 laminin genes in S. schlegelii through genomic analysis and qPCR experiments. The expression of laminin genes, especially lama4 and lama5, increased significantly during the early stage of gestation, suggesting their involvement in cell proliferation, migration, and tissue expansion in the ovary of S. schlegelii. In situ hybridization of lama4 confirmed its strong expression in the follicular pseudoplacenta at the blastula stage.

Summary: In this study, a new type of folliculogenesis and follicular placentation in Sebastes schlegelii was demonstrated. Hormone imbalance might be an important factor driving the proliferation and invasion of placental cells. Additionally, the high expression of conserved genes related to mammalian placentation in follicular placenta suggests high convergence in vertebrate placenta evolution.
