Summary: The study found that using post-consumer food waste from restaurants as an ingredient in rainbow trout feed can be done without negatively impacting fish growth, and may even lead to better growth rates at a 20% waste inclusion level. This suggests the potential for using food waste in trout feed, which could help mitigate environmental consequences of food waste disposal.

Summary: This paper is a documentation of the feed utilization in rainbow trout farming in Norway in 2020. A total of 89,667 tonnes of rainbow trout were produced, and the feed ingredients used included marine protein sources, vegetable protein sources, and micro ingredients, with a small portion of salmon feed also used. Norwegian fish meal and fish oil accounted for 8.8% of the ingredients, while the remaining ingredients were imported.

Summary: This study aimed to investigate the effects of photoperiod and feeding regime on the growth, feed utilization, and food anticipatory activity (FAA) of juvenile rainbow trout. The results showed that scheduled feeding groups had better growth and feed utilization compared to the random feeding group. There was no difference between the mid-dark stage feeding and mid-light stage feeding groups. Food can strongly synchronize the feeding rhythm of juvenile rainbow trout even without light zeitgeber.

Summary: The aim of this study was to investigate the effects of fasting and refeeding on body condition, gut physiology, and microbiota in reared rainbow trout. The results showed that fasting and refeeding had significant effects on the fish's weight, visceral condition, and liver condition, as well as the gut microbiota. Feed deprivation led to dysbiosis in the gut microbiota, but these effects were gradually mitigated by refeeding.

Summary: The study found that adding pot marigold powder at 1%, 1.5%, and 2% levels to the diet of rainbow trout significantly improved growth, immune response, and disease resistance. In addition, the 1% and 1.5% MP groups showed increased digestive enzyme activities and antioxidant capacity. The highest survival rate after Yersinia ruckeri infection was observed in the 1.5% MP group compared to the control group.

Summary: This study aimed to investigate the correlations between fish feed efficiency (FE) and potential predictive criteria in rainbow trout. The results showed significant correlations between feed conversion ratio (FCR) and residual feed intake (RFI) with feed intake, but no significant association was found with body weight variations as a predictive criterion. In addition, a strong positive correlation was found between the number of feed demands in feeding behavior and RFI. Overall, this study provides guidance for the aquaculture industry in assessing feed efficiency in fish.

Summary: The study revealed that Rainbow Trout accumulated both intracellular and extracellular microcystins in all tissues within 24 hours after exposure to a certain concentration, leading to dysregulation of proteins associated with cytoskeletal structure, stress responses, and DNA repair, ultimately causing sublethal toxicity effects.

Summary: Accurate feed evaluation is crucial for feed formulation in aquaculture. This study tested a net energy (NE) evaluation method in predicting growth performance of rainbow trout feeds, showing that replacing fat with carbohydrates reduced energy utilization for growth, especially at high carbohydrate levels. The NE approach using linear efficiencies of digestible macronutrients demonstrated improved prediction precision of growth rate compared to the digestible energy (DE) approach. However, assuming a curvilinear effect of carbohydrates did not lead to an improved prediction of growth rate in this study.

Summary: Proteomics was used to compare the protein profiles of efficient and inefficient Chinook salmon, revealing enrichment of lipid metabolism-related gene ontology terms in the liver of efficient fish and protein metabolism pathways in the white muscle. Inefficient fish showed enrichment of protein processing and proteolysis terms in the liver. This study provides a preliminary understanding of the molecular landscape of feed efficiency in Chinook salmon.

Summary: This study investigated the physical stability and interfacial properties of O/W emulsions stabilized with fish skin gelatin and pea protein. It was found that emulsions with higher presence of FG exhibited greater physical stability, with smaller average particle size. Analysis using confocal laser scanning microscopy and differential scanning calorimetry revealed the presence of proteins at the emulsion interface and their thermal properties, respectively.

Summary: This review focuses on the water holding properties of Atlantic salmon, evaluating the methods used to measure them and how pre- and postmortem factors, processing, and preservation methods influence these properties and their correlations to other quality parameters. Various methods are available to measure water holding capacity (WHC), with the centrifugation method being the most prevalent but other non-invasive and cost-effective approaches increasingly preferred. The diversity of methods makes direct comparison of results from previous research relative unless the same method is used with the same conditions.

Summary: The study found that the duration of dry salting affects the texture, color, water activity, and salt uptake of smoked salmon. There were differences in color and water activity between salmon stored in refrigerated seawater and ice during cold smoking. Drip loss and color changes were significantly influenced by processing steps.

Summary: This study investigated the interaction between fish skin gelatin (FG) and pea protein isolate (PPI) at the air-water interface before and after ultrasound treatment. The results showed that the treatment slightly affected the properties of the proteins but did not significantly impact their behavior at the interface. However, when combined, the proteins formed higher molecular weight aggregates, exhibited higher foam stability, and had lower interfacial tension.

Summary: The consumption of edible insects can be a beneficial alternative to conventional food supply chains due to the issues of water wastage, land deficit, undernutrition, and starvation. In addition to their nutritional benefits, insect proteins possess various functional properties. However, more research is required to understand the impact of industrial treatments on insect proteins and their functionalities.

Summary: This study investigates the effect of tryptic hydrolysis and ionic strength on the oil/water interfacial properties of soluble pea protein hydrolysate (SPPH). The results show that tryptic hydrolysis leads to the creation of lower molecular weight polypeptides and a more disordered and flexible structure. In terms of bulk properties, higher particle size and turbidity are observed at 0.4 M NaCl. However, the addition of NaCl negatively affects the elasticity and strength of the interfacial film.
