Summary: Using germ cell-free (GCF), sterile, dnd-knockout salmon for farming can solve the problems associated with precocious maturation and genetic intmgression of farmed breeds into wild populations. The GCF phenotype of salmon is similar to wild type (WT) counterparts in terms of growth and welfare, with the advantage of never maturing.

Summary: The study found that the mechanisms driving range-wide reductions in Atlantic salmon marine survival are hindered by a lack of understanding of their oceanic ecology and distribution. The individual salmon migrated further and in different directions than previously reported, showing increased diving activity near oceanographic fronts, highlighting the importance of these regions as feeding areas. Differences in oceanic distribution among individuals and populations may contribute to variations in growth and survival due to environmental conditions.

Summary: The study found that inclusion of 20 and 40 g/kg of HORM in diets for juvenile Atlantic salmon resulted in acceptable growth performance. Transcript expression of inflammation-relevant genes responded to dietary HORM, indicating the need for further research to determine if higher levels of HORM may be associated with inflammation and negative effects on fish health.

Summary: Infestations with salmon lice and the management of these lice pose significant challenges and costs in marine salmonid aquaculture. Treatment against salmon lice, particularly non-medicinal methods, can lead to stress and physical injuries in Atlantic salmon, resulting in reduced appetite and increased mortality. This study analyzed production data from Norwegian aquaculture companies to estimate the short-term growth loss of Atlantic salmon following different treatments for salmon lice removal. The results showed that non-medicinal treatments had a greater negative impact on growth compared to medicinal treatments, and the timing of treatment played a role in the treatment outcome.

Summary: This study examined the effects of various dietary riboflavin levels on the growth performance, body composition, and antioxidant capacity of coho salmon post-smolts. The results showed that the diet with 31.81 mg/kg riboflavin significantly improved the specific growth rate and influenced muscle lipid content and various physiological indicators.

Summary: The elevated salmon louse infection pressure caused by salmon farming poses a major threat to wild Atlantic salmon. This study found that lice had a negative impact on the growth and survival of wild Atlantic salmon in seawater, but only affected the length growth in freshwater after the lice had detached. The parasites did not affect the size of the fish's reproductive organs.

Summary: Obtaining desired phenotypic traits in aquacultural production of Atlantic salmon is still a challenge, and the presence of host-associated microorganisms might contribute to this challenge. Understanding the factors that shape the microbiota is crucial for manipulating it towards desired host traits. In this study, DNA methylation differences associated with a tenacibaculosis outbreak and microbiota displacement in Atlantic salmon were investigated, revealing potential genes involved in host-microbiota interactions and the importance of considering epigenetic factors in manipulating farmed fish microbiota.

Summary: This study investigated the effect of salmon protein hydrolysate (FPH) on prion infection and the impact of partially replacing fish meal with salmon hydrolysate on the growth, digestibility, and gut health of Atlantic salmon. The results showed that salmon hydrolysate was free from prions and the diets containing hydrolysate improved the growth rate and digestion of salmon without affecting gut health.

Summary: The repeated warm water treatments led to significantly increased prevalence and/ or severity of scale losses, snout wounds, various eye problems, and active fin injuries as well as a significantly reduced specific growth rate in Atlantic salmon. The fish displayed an immediate, strong behavioral reaction when exposed to warm water, which was likely the main cause of the detected injuries.

Summary: After fifty years of salmon farming, the study found that genetic introgression from farmed escapees can accelerate the growth rate of wild Atlantic salmon and lead to earlier seaward migration and sexual maturity, with significant variation among populations. Additionally, variation at major-effect loci associated with age at maturity was minimally affected by farmed genetic ancestry.

Summary: Precision feeding aims to provide optimal growth and performance for farmed animals while minimizing feed waste. This study examined the relationship between meals, feed deprivation time, and the feed consumed by Atlantic salmon post smolts. The results showed that the time between meals and the size of the previous meal significantly affected the feed intake in the following meal, suggesting the possibility of optimizing meal size.

Summary: Traditional genetic markers and SNP panels have been used to study the genetic variation and genes related to maturation in Atlantic salmon. However, the association between the locus coding for mMEP-2* and maturation remains unclear. In this study, a method was developed to characterize the alleles of this locus and a relationship between SNP G and early maturation was found in the salmon population of the Bidasoa River.

Summary: Feeding Nile tilapia diets with organic trace mineral supplementation at different doses showed that the fish can modulate intestinal morphology based on the doses given, with no effect on growth but potential harm at excessive levels. Body deposition of Fe, Zn, and Cu were highest at specific supplementation levels.

Summary: Maturation of Atlantic salmon male postsmolts is a concern in aquaculture due to its negative impact on growth, welfare, and seawater readiness. The study assessed the effect of temperature and photoperiod on maturation in male postsmolts and found that rearing salmon at 15 degrees C promoted early maturation. The use of high water temperature and winter signal regimes in the aquaculture industry may increase the risk of early maturation and poor hypo-osmoregulatory performance.

Summary: The study found that only 31% of koi from PCR-positive KHV fish groups were seropositive in ELISA testing. Furthermore, over 34% of seropositive but PCR-negative fish had titres of >1/400. These results highlight the concerns related to carp populations that have been screened for KHV using molecular methods alone and emphasize the need for serology to accompany molecular testing in carp for this notifiable virus.

Summary: The study demonstrates that membrane vesicles (MVs) from Gram-positive bacteria are capable of transferring beta-lactam antibiotic-resistant substances to antibiotic-sensitive Gram-negative bacteria, resulting in increased resistance to beta-lactam antibiotics.MVs play a role in transferring substances from Gram-positive to Gram-negative bacteria, shown by the release of MVs from RC85-T that were able to protect beta-lactam-susceptible bacteria from beta-lactam antibiotics.

Summary: Complex gill disorder (CGD) is an important condition in Atlantic salmon aquaculture, but the roles of the putative aetiological agents in the pathogenesis are uncertain. This study shows that the loads of certain pathogens are significantly associated with the severity of CGD, and water temperature and management factors also have an impact on gill lesions.

Summary: In recent years, emerging and re-emerging diseases have had a significant economic impact on the tilapia industry. Without effective management and appropriate biosecurity measures, infectious diseases will continue to challenge the sustainability of global tilapia aquaculture. Enhancing immune response and improving husbandry management can help reduce the impact of diseases.

Summary: The early host-pathogen interaction between European seabass and Betanodavirus was examined by infecting juvenile fish with RGNNV. The study found that the host's immune system was activated shortly after infection, and significant changes in hematological, antioxidant, and immunological responses were observed. Furthermore, the peak expression of certain immune markers coincided with disease symptoms and high levels of fish mortality.

Summary: This review assesses the representation of seafood in recent food security literature and finds that seafood is under-researched compared to terrestrial production systems. The study also reveals a lack of research on the interaction between terrestrial and aquatic systems. Therefore, there is a need for more attention to be given to the role of seafood in global food security and for its integration into interdisciplinary research.
