Summary: By analyzing the nutritional composition of rainbow trout skin and studying the effects of different diets, it was found that the skin can be a promising source of n-3 LCPUFA. Reusing the skin of farmed fish can help reduce food industry by-products, address the shortfall of n-3 LCPUFA, and potentially lead to the development of functional foods and supplements.

Summary: This study evaluated the effects of two experimental diets on the gut microbiome of rainbow trout, suggesting that these diets significantly influenced the diversity and abundance of gut bacteria and fungi. The differences in gut microbiota between the control group and the groups with alternative diets were mainly observed at the genus level. Furthermore, the alternative diet groups exhibited more beneficial microbes positively correlated with plant protein or rapeseed oil.

Summary: This study investigated the antifungal activity of essential oil nanoemulsions from thyme, laurel, lavender, cumin, cinnamon, and eucalyptus against Saprolegnia parasitica. Thyme essential oil nanoemulsions showed the highest potency, while cinnamon essential oil nanoemulsions were less effective. In rainbow trout eggs experimentally infected with S. parasitica, thyme essential oil nanoemulsions and the positive control had the highest survival rates.

Summary: The study examined the potential of black soldier fly larvae oil (BSLO) as a replacement for fish/soy oil in rainbow trout feed, finding that it did not negatively impact growth performance, whole-body composition, or nutrient retention, and could modulate the expression of fatty acid metabolism-related genes in rainbow trout.

Summary: Microalgae have the potential to address the shortages of food and nutrition as a sustainable biofactory. They can produce high-value bioactive compounds, including n-3 polyunsaturated fatty acids (PUFA), which have various health benefits. However, the supply of n-3 PUFA is facing challenges due to global warming and overfishing. Cultivating microalgae to meet the market demand and provide unique fatty acids for specific populations is an important area of research.

Summary: The study investigates the preparation process of linseed oil body emulsion and its characteristics after adding fish oil, using H-1 low-field nuclear magnetic resonance to analyze their chemical and structural properties, as well as stability under thermal oxidation. The results show that both linseed seed emulsion and linseed fish oil emulsion did not undergo intense oxidation process, effectively reducing the thermal oxidation of PUFA.

Summary: The study found that reducing protein content by 30% and replacing it with carbohydrates in the diet of rainbow trout broodstock during gametogenesis did not have adverse effects on offspring. This suggests the feasibility of increasing the proportion of plant-derived carbohydrates in female broodstock diets to replace fishmeal proteins.

Summary: This study investigated the effects of tuna viscera hydrolysate (TVH) on the growth performance, nutritional response, intestinal and liver health, and resistance to Streptococcus iniae in juvenile pompano. The results showed that TVH at 10% concentration significantly improved the growth performance and specific growth rate of juvenile pompano. TVH had no significant effect on feed utilization, somatic indices, and proximate composition. However, it reduced phenylalanine and valine levels. In addition, TVH enhanced the disease resistance of pompano against Streptococcus iniae.

Summary: Driven by consumer demand and government policies, the use of synthetic additives in aquafeed needs to be replaced with sustainable and natural alternatives. Seaweeds, as a sustainable marine source, contain bioactive phenolic compounds that can be used in various applications such as food, animal feed, aqua feeds, or microencapsulation. Seaweed phenolics, specifically phlorotannins found in brown seaweed, have unique structures and multiple antioxidant mechanisms. They can bind to proteins through covalent and non-covalent bonds, exhibiting specific bioactivities. Additionally, they can enhance the rheological and mechanical properties of food-grade delivery systems, showing the versatility of seaweed phenolics.

Summary: The inclusion of protein hydrolysates in the diet of larval largemouth bass has been shown to improve growth performance, digestive enzyme activities, protein metabolism, and intestinal health. This is achieved through the upregulation of specific genes related to amino acid transport, activation of the TOR pathway, inhibition of the AAR pathway, modulation of cytokine expression, and changes in the intestinal microbial community. These findings highlight the potential benefits of protein hydrolysates as a supplement in fish larval diets and provide insights into the underlying mechanisms of their actions.

Summary: Australian abalone aquaculture is characterized by a prolonged culture period and slow and variable growth. Water temperature is a crucial factor influencing abalone's physiology and energetics, leading to changes in their nutritional requirements. Feeds are generally formulated based on the nutritional requirements at the optimal temperature, but there is a need to optimize dietary protein levels to match temperature-specific requirements during extreme conditions.

Summary: This study aimed to evaluate the effects of dietary protein inclusion level on the growth performance and nutrient utilization of Australian hybrid abalone. The results showed that higher dietary protein levels significantly improved the growth performance of abalone when water temperatures exceeded 17 degrees Celsius. However, during cooler seasons or when water temperatures were lower, maintaining lower protein levels may be beneficial.

Summary: Research has found that Australian seaweeds are rich in essential dietary minerals, particularly those that are commonly deficient in human diets. There are significant differences in the mineral composition of different seaweed species, although individual element concentrations vary in complex ways. Optimal nutritional benefits can be achieved by regularly consuming a variety of seaweed species. However, further research is needed to reduce iodine content in some species to maximize the health benefits of regular consumption of these Australian seaweeds.

Summary: The production of farmed Atlantic salmon is currently dependent on finite marine resources such as fish oil and fish meal. Reducing the inclusion of these resources in aquafeed can allow for sustainable growth of the industry until 2100 and beyond, while still meeting the dietary needs of humans for omega-3 fatty acids.
