Behaviour of growth hormone transgenic coho salmon Oncorhynchus kisutch in marine mesocosms assessed by acoustic tag telemetry

Abstract: Underwater acoustic tag telemetry was used to assess behavioural differences between juvenile wild-type (i.e. non-transgenic, NT) and growth hormone (GH) transgenic (T) coho salmon Oncorhynchus kisutch in a contained simulated ocean environment. T O. kisutch were found across days to maintain higher baseline swimming speeds than NT O. kisutch and differences in response to feeding were detected between T and NT genotypes. This is the first study to assess behaviour of GH transgenic salmonids in a marine enviro… Show more

“…A comparable proportion of genes were found to be higher or declined in the same course by domestication or GH transgenesis relative to wild-type, suggesting that changes in specific mRNA are not being strongly inclined by a global regulation of mRNA levels (mRNA: rRNA ratios). Therefore, for these domesticated and GH transgenic strains with a common phenotype, it seems that many of the same genes are complicated and are adapted in parallel ways by both types of genetic alteration from wild-type (Devlin, Biagi, & Yesaki, 2004).…”

“…95,96 An acoustic telemetry system selects appropriate acoustic tag types and parameters according to the individual fish size and the study period for monitoring fish trajectory, 97 which has gradually become the most important means of fish behaviour research. 32,98 At present, the application of the research results of acoustic telemetry systems mainly includes the swimming pattern of fish, 99 the survival situation of fish, 100 the behavioural differences of fish, 101 and the movement parameters of telemetered fish. 102 The acoustic telemetry system is mainly composed of an acoustic tag signal receiver, hydrophone, acoustic tag and computer.…”

“…Acoustic tag tracking technology was used to obtain fish behavioral trajectories, some physical and mathematical models were established (Cai and Li, 2012;Romine et al, 2014). Acoustic tag tracking technology is used to evaluate the behavior, survival and behavior changes of fish in the ecosystem (Everson et al, 2013;Schultz et al, 2015;Hollo et al, 2017). In summary, it can see that the acoustic tag tracking technology is mainly used in fish habits, migration, fish stock, fish species protection and habitat restoration.…”
