Summary: The study found that differential expression of maternal transcripts between low- and high-quality eggs in rainbow trout can overlap in different populations. There is greater similarity in dysregulated transcripts within year classes of the same line, suggesting insight into causes of decreased viability within a hatchery population. Although many DEGs were identified, there is considerable variability in transcript abundance among eggs of similar quality, making it highly improbable to predict egg quality based on just a few genes.

Summary: In this study, the virulence phenotypes of two Flavobacterium columnare (Fc) isolates were characterized against rainbow trout at different life stages, revealing stark differences in their pathogenicity towards eyed eggs and alevin. These findings suggest a potential model system for studying virulence kinetics and alternative pathogenic pathways.

Summary: Evaluating the reproductive success of female fish requires a thorough assessment of egg characteristics, including number, size, and viability. A system called VisEgg was developed to automatically capture images of rainbow trout eggs and measure characteristics such as size and quantity, as well as assess the viability of unfertilized eggs before fertilization. This tool proved to be a convenient and reliable way to obtain individual measurements of trout eggs and separate out viable from non-viable eggs.

Summary: This study compared the emulsifying properties of lecithins from different sources and found that aquatic origin lecithins (RL and WL) have higher phospholipid contents, which can form more stable emulsions than terrestrial origin lecithins (HL and SL).

Summary: Chemical compounds like formalin are commonly used to prevent fungal infections and treat external parasites in fish eggs and hatchery-reared fish. However, formalin exposure can lead to mortality, depending on the concentration used and rearing conditions. Different strains of rainbow trout also exhibit varying sensitivity to formalin. Therefore, it is important to consider formalin concentration, rearing conditions, and strain differences before implementing large-scale treatments.

Summary: This study aimed to evaluate the short-term effects of diets containing different carbohydrates on rainbow trout. The results showed that rainbow trout fed with diets containing carbohydrates were able to maintain glucose sensing capacity and regulate appetite, and it was found that there were sex differences in the genes related to glucose sensing and appetite regulation.

Summary: Biomedical and social scientists are questioning the traditional understanding of biological sex, arguing that it is a spectrum rather than a binary trait. While efforts for inclusivity should be supported, denying biological sex seems to stem from a lack of understanding of evolution and imposes human concepts on other species.

Summary: Exposure to warm temperatures during the juvenile stage in rainbow trout has negative impacts on male gonad development, sperm quality, and offspring deformity rates, although the remaining offspring show better survival and growth rates under the same conditions as their parental fish. The study suggests that thermal stress may elicit intergenerational thermotolerance, impacting fish adaptation and coping with global warming.

Summary: The study indicates that low water salinity negatively impacts final oocyte maturation, ovulation, and egg quality in fish, leading to delayed ovulation and reduced oocyte viability. Impaired oocyte hydration and decreased gene expression levels of key players in the ovulatory process were observed in individuals with severe phenotypes exposed to low water salinity. The disrupted ovulatory gene expression program suggests a potential mechanism for the negative influence of low salinity water on the maturation-ovulation process.

Summary: Reports of natural hybridization in Laminariales are limited, particularly in Ecklonia. The study identified morphologically atypical Ecklonia specimens suspected to be hybrids between different species, confirmed through DNA genotyping and microsatellite markers. This research provides strong genetic evidence for the existence of intra- and inter-generic hybrids of Ecklonia in the field.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
