AI Article Synopsis
- The study investigated how different feeding habitats affect antioxidant levels (vitamin A, E, C, ß-carotene, and selenium) and malondialdehyde (MDA) in rainbow trout flesh.
- The analysis revealed that wild rainbow trout (WRT) had the highest levels of vitamins and selenium, while pond reared trout (PRRT) exhibited the highest MDA levels.
- The findings suggest that the feeding environment significantly influences the nutritional quality of rainbow trout, with wild specimens being the most beneficial.
Article Abstract
The present study was aimed to find the effect of feeding habitats on the amounts of some antioxidants (vitamin A, E, C, ß-carotene and selenium) and malondialdehyde (MDA) levels in the flesh of rainbow trout (Oncorhynchus mykiss). For this purpose, vitamins (A, C and E), β-carotene amounts and malondialdehyde (MDA) levels were determined by HPLC and selenium amount was determined by fluorometric method in the flesh of rainbow trout obtained from various feeding habitats. The highest amounts of vitamins (A, C and E), β-carotene and selenium were found in the flesh of wild rainbow trout (WRT), followed by cage reared rainbow trout (CRRT) and pond reared rainbow trout (PRRT). However, the levels of MDA in the flesh of PRRT were the highest, followed by CRRT and the lowest in WRT.

6PPD-quinone (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone), a transformation product of the antiozonant 6PPD (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine) is a likely causative agent of coho salmon (Oncorhynchus kisutch) pre-spawn mortality. Stormwater runoff transports 6PPD-quinone into freshwater streams, rapidly leading to neurobehavioral, respiratory distress, and rapid mortality in laboratory exposed coho salmon, but causing no mortality in many laboratory-tested species. Given this identified hazard, and potential for environmental exposure, we evaluated a set of U.

In May 2021, the M/V ship fire disaster led to the largest maritime spill of resin pellets (nurdles) and burnt plastic (pyroplastic). Field samples collected from beaches in Sri Lanka nearest to the ship comprised nurdles and pieces of pyroplastic. Three years later, the toxicity of the spilled material remains unresolved.

Infectious hematopoietic necrosis virus (IHNV) is a serious pathogen in the salmonid aquaculture industry and leads to economic losses in the world. This study aimed to develop a new oral DNA vaccine designed to protect rainbow trout against infection by IHNV. Fish were administered via the oral route by the attenuated Salmonella enterica serovar Typhimurium as a carrier of pcDNA3.

Single-cycle viruses hold great promise as fish viral vaccines due to their high protective efficacy. Although the efficacy of the vaccine in olive flounder and rainbow trout has been proven through previous research, safety must be additionally proven considering the environment of use for commercialization. This study comprehensively assesses the safety of rVHSV-GΔTM and its impact on both the host and the surrounding environment, including the coastal habitat of nearby species and seawater.
