Summary: This study investigated the spatiotemporal variability of juvenile Atlantic cod growth and survival using Barents Sea bottom survey data, finding that the location within the Barents Sea where age-1 cod are distributed affects their growth and survival. Year-classes in the western Barents Sea had higher mortality but faster growth compared to those distributed farther east, indicating a significant role of distribution in the survival and growth of age-1 cod.

Summary: The change in temperature affects the composition and function of intestinal microbiota of juvenile Eriocheir sinensis. 23-30 degrees C is the optimal water temperature for the growth of juvenile E. sinensis. The intestinal microbial abundance and diversity vary with different water temperatures, and the functional pathways influenced by water temperature include metabolism, immunity, and growth.

Summary: The use of in-feed probiotics in different growth stages has positive effects on growth performance, hematological parameters, gut microbial content, and morphological structures of pangasius fish, as well as increasing fry survival rate. The treated groups showed significantly higher growth performances, survival rates, and levels of specific hematological parameters compared to the control group, indicating the potential benefits of using probiotics in nurseries for pangasius.

Summary: The study suggests introducing a microcapsule diet for Mekong giant catfish larvae at 30 days post hatching to reduce dependency on live feeds. Results show that introducing an inert diet after 14 days post hatching is beneficial for the larvae. In a 28-day feeding experiment, transitioning to a microcapsule diet improved weight gain rate and specific growth rate without affecting survival rate.

Summary: This study evaluated the effects of three probiotic bacteria on the growth performance, nutritional value, and microbial load of mealworm larvae. The results showed that Enterococcus faecalis had the best effects on larvae weight and length gain, while Bacillus toyonensis and Bacillus subtilis increased the dry matter content. Addition of probiotics led to increased protein content, reduced fat content, and decreased microbial load in the larvae.

Summary: Although nursing pike-perch larvae indoors increases fish mortality, it leads to improved growth later in life and lower feed conversion ratio. Therefore, indoor rearing can shorten the growth period and increase fish yields.

Summary: This study investigates whether juvenile brown trout exhibit sex-specific life histories and finds that stocking and other environmental factors may affect their sex-specific growth. Females begin sex differentiation earlier than males, and the growth rates of juveniles vary depending on location and origin of the fish.

Summary: Ornamental fish husbandry faces challenges and losses, such as transport stress and disease outbreaks. This review discusses measures to prevent or control fish diseases and the role of natural and sustainable microbial feed additives (such as probiotics, prebiotics, and synbiotics) in enhancing the health, reducing transport stress, and promoting growth and reproduction of farmed ornamental fish. The review aims to fill the knowledge gap in advanced and sustainable practices in ornamental fish production.

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.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
