Summary: Steelhead fry reared in Oregon hatcheries have a high mortality rate and show signs of vitamin B1 deficiency. This study explores whether thiamine supplementation can improve their health and survival. The results demonstrate that thiamine-treated fry had significantly higher survival and growth rates compared to those without thiamine supplementation.

Summary: This study aimed to evaluate the impact of suspended sediments on fish, specifically in terms of endocrine responses caused by ECs released from sediments. The findings demonstrated that ECs from sediments can have endocrine-disrupting effects on fish, emphasizing the importance of considering sediment quality criteria during flood events.

Summary: Fish hatcheries release billions of fish into the wild every year, but this practice can negatively impact wild fish populations through competition and hybridization with native species. In Montana's Flathead River, Westslope Cutthroat Trout are threatened by hybridization with invasive Rainbow Trout, leading to genomic extinction. By analyzing otolith Sr-87/Sr-86 ratios, researchers were able to identify hatchery-origin Rainbow Trout in a tributary, highlighting the conservation risks posed by invasive species.

Summary: Salmonid fish raised in hatcheries often have lower fitness compared to wild fish, potentially due to hatcheries inadvertently selecting for traits that enhance growth but are maladaptive in the wild. Offspring of hatchery origin grow faster in hatchery conditions but have lower survival in the wild. There is no evidence that reducing the fat content in hatchery feed would reduce variation in body size among families.

Summary: Rhinoceroses are facing an uncertain future due to human-induced population-size reductions. Research on rhinoceros genomes reveals an early divergence between African and Asian species, evidence of past hybridization, and loss of genetic diversity.

Summary: The present research demonstrates that dietary exposure is an alternative route of geosmin uptake in Rainbow Trout fillets, leading to a significant increase in geosmin concentrations. This finding is important for further investigation of sensory quality and off-flavor mitigation strategies for farm-raised fish.

Summary: Disease prevention through vaccination is the most appropriate method for pathogen control in aquaculture, but oral vaccines face technical problems in aquatic animals. This study explores different molecules as oral adjuvants and finds that LPS shows strong immunostimulatory potential and could be safely used as a mucosal adjuvant in rainbow trout.

Summary: The study examined the changes in technological and organoleptic qualities of female rainbow trout flesh after spawning and found that fillet quality gradually recovered over a period of approximately 24 weeks post-spawning. By around 1400 degree C.days after spawning, the quality parameters of the flesh were mostly restored to pre-spawning levels.

Summary: The study showed that PE microparticles have toxic effects on rainbow trout, affecting various health indices such as intestinal disintegration, changes in blood indices, and damage to liver and kidney. This findings raise concerns about potential threat to aquatic ecosystems and human health.

Summary: The aqueous methanolic extract of thin-skinned plum showed positive effects on the growth, immune response, and resistance to a pathogenic bacterium in rainbow trout. Specifically, it improved innate immunity, survival against Yersinia ruckeri, and decreased the feed conversion ratio level significantly.

Summary: This study demonstrates the potential of contrast-enhanced ultrasound (CEUS) imaging for measuring organ blood flow in fish, visualizing contrast enhancement in the liver of rainbow trout, and detecting the effects of drugs on blood flow. CEUS shows promise for exploring different organs, fish species, and the impact of chemical contaminants in future research.
