Summary: The efficacy of fisheries management strategies depends on carrying out stock assessment and management actions at appropriate spatial scales. This study investigated the population genomics of a heavily exploited snapper species along the Australian coastline to understand population structure, connectivity, and the compatibility of current management practices. The results revealed low genetic differentiation and high connectivity across Western Australia, but also identified genetic discontinuities in certain regions, suggesting a need for a review of current spatial management.

Summary: The genetic homogeneity of Snapper, Chrysophrys auratus, in Western Australian waters and the variation of its genetic composition among regions in Australasia are investigated using microsatellite loci. The results show that Snapper is genetically homogeneous along the majority of its range in Western Australia, with low and non-significant genetic differentiation between locations. The genetic composition is influenced by ocean currents, leading to distinct genetic stocks in different areas.

Summary: This study investigated the impacts of climate change stressors on the Australasian snapper in New Zealand. The results showed that the snapper's metabolic performance remained high even in warm conditions, and they were able to adapt well to hypoxia. Therefore, despite the threat climate change poses to marine organisms, a temperature of 25°C may be metabolically optimal for the Australasian snapper in Northern New Zealand.

Summary: Structured habitats are important for juvenile fish, providing food and refuge from predators. In this study, potential predators of post-settlement snapper were identified, and their diet was investigated. Tank experiments showed that post-settlement snapper may use habitat and aggregate together under threat of predation. The pulsed nature of predation and the significance of predation in determining habitat association were discussed.

Summary: This study compares a wild strain and a selectively bred elite strain of Chrysophrys auratus. The results show that the selectively bred strain exhibits significantly improved performance in all measured traits, including survival rate, weight gain, and feed conversion ratio. In addition, the selectively bred strain has lower intra-cohort variation and is less sensitive to feeding frequency. This suggests that genomics-assisted selective breeding has great potential for the farming of C. auratus in Australasia.

Summary: In southeastern Australia, population genomic differentiation in snapper is concordant with coastal biogeographic boundaries and related to spawning and recruitment dynamics. The current management boundaries align with genetic breaks at bioregional boundaries or local-scale variation. This study highlights the value of population genomic surveys in uncovering stock boundaries and demographic variation related to spawning and recruitment in species with high dispersal potential, and emphasizes the importance of marine biogeography in shaping population structure in commercially important species.

Summary: Oral astaxanthin supplementation significantly improved skin moisture content and elasticity, but did not significantly decrease wrinkle depth compared to placebo. Open-label, prospective studies suggested slightly protective effects of topical and oral-topical astaxanthin applications on skin ageing.

Summary: Physiological stress patterns of marine organisms play a crucial role in determining the thermal limits of fish in their natural habitats. This study aims to investigate the biochemical responses of red porgy to constantly changing field conditions, bridging the knowledge gap in its thermal physiology and considering the Mediterranean Sea as a climate change hotspot. Various biochemical indicators, including Heat Shock Response, MAPKs pathway, autophagy, apoptosis, lipid peroxidation, and antioxidant defense, exhibited a seasonal pattern, with higher levels correlated with increasing seawater temperature in spring. The observed physiological responses in red porgy suggest its ability to adapt to a wide range of temperatures, supporting the concept of eurythermy.

Summary: The study evaluated the effects of moderate and high dose dietary supplementation of astaxanthin on egg quality and laying hens' health status. It was found that moderate dose supplementation efficiently improved egg yolk color and laying hens' health status, while high dose supplementation showed positive effects but with decreased efficacy compared to moderate doses. Astaxanthin had no adverse effects on laying hens' performance and health status but may not be valuable for egg fortification at high doses.

Summary: Through the transcriptome analysis of goldfish skin after challenge with Gyrodactylus kobayashii, this study identified numerous differentially expressed genes and immune-related pathways. The validation of selected genes using qRT-PCR showed a reliable consistency with RNA-Seq data. Additionally, higher ALP activity and NO content in infected goldfish serum suggested a strong immune response against the parasite.

Summary: The study found that the choline supplementation did not have significant effects on the liver lipid composition of juvenile yellowtail kingfish, but did have some impacts on liver histology and plasma biochemistry. Phosphatidylcholine was the main component of liver phospholipids, and the proportion of long chain polyunsaturated fatty acids in the liver remained unchanged regardless of treatments. The health indicators of juvenile yellowtail kingfish can be affected by sub-optimal temperatures and diets without supplemented choline, although there was no strong evidence of compromised health in fish reared at either temperature.

Summary: This study investigated the dietary methionine and cysteine requirements of Yellowtail Kingfish, finding that cysteine can spare up to 40.4-49.2% of methionine in the total sulfur amino acid requirement. Optimal levels of these amino acids are crucial for growth and feed efficiency in YTK, with sub-optimal levels potentially leading to cataract development.
