“…The acid and alkaline phosphatases have been showed as indicatives of tissue damage in other animals (Molina, 2005; Moreno, 2003). These results would also be in accordance with the maintenance of redox homeostasis previously described for fish fed with IM diets, since an increased oxidative stress environment can be related to tissue damage (Wang, 2019; Wu & Zhou, 2013).…”

Potential use of black soldier fly ( Hermetia illucens ) and mealworm ( Tenebrio molitor ) insectmeals in diets for rainbow trout ( Oncorhynchus mykiss )

Global population is in constant growth, and so is its global protein demand. Aquaculture has been highlighted as one of the best possibilities to satisfy animal protein demand due to the remarkable efficiency of fish growth in comparison with terrestrial animals (Fry, 2018), and to its fast development as an industrial food sector. The most commonly farmed fish require aquafeeds with a high content in protein, whose demand has been traditionally satisfied with a significant inclusion of fishmeal (FM) in fish feeding formulations. In order to favour this continuous development in a sustainable way, the scientific and industrial communities have invested big efforts on

“…In addition, analysis of gene ontology found overrepresentation of biological processes primarily related to regulation of metabolic processes, and immune response. The insulin signalling pathway may relate to both metabolic processes (Babbitt et al, 2010; Zhang et al, 2018) and immunity (Cheng et al, 2017; Wang et al, 2019; Yada & Tort, 2016).…”

Environmentally associated chromosomal structural variation influences fine‐scale population structure of Atlantic Salmon (Salmo salar)

Chromosomal rearrangements (e.g., inversions, fusions, and translocations) have long been associated with environmental variation in wild populations. New genomic tools provide the opportunity to examine the role of these structural variants in shaping adaptive differences within and among wild populations of non‐model organisms. In Atlantic Salmon (Salmo salar), variations in chromosomal rearrangements exist across the species natural range, yet the role and importance of these structural variants in maintaining adaptive differences among wild populations remains poorly understood. We genotyped Atlantic Salmon (n = 1429) from 26 populations within a highly genetically structured region of southern Newfoundland, Canada with a 220K SNP array. Multivariate analysis, across two independent years, consistently identified variation in a structural variant (translocation between chromosomes Ssa01 and Ssa23), previously associated with evidence of trans‐Atlantic secondary contact, as the dominant factor influencing population structure in the region. Redundancy analysis suggested that variation in the Ssa01/Ssa23 chromosomal translocation is strongly correlated with temperature. Our analyses suggest environmentally mediated selection acting on standing genetic variation in genomic architecture introduced through secondary contact may underpin fine‐scale local adaptation in Placentia Bay, Newfoundland, Canada, a large and deep embayment, highlighting the importance of chromosomal structural variation as a driver of contemporary adaptive divergence.

“…To date, studies have found that heat stress has various effects on the liver. Hundreds of liver genes were differentially expressed after heat stress in different animals, including rabbits [ 16 ], fish [ 53 , 54 ], broilers [ 55 ] and mice [ 56 ], and the expression levels changed differently over time [ 57 ]. In addition, the alternative splicing of liver genes in fish was also affected by heat stress [ 32 , 58 ].…”

Heat stress is one of the most severe challenges faced in livestock production in summer. Alternative splicing as an important post-transcriptional regulation is rarely studied in heat-stressed animals. Here, we performed and analyzed RNA-sequencing assays on the liver of Sprague-Dawley rats in control (22 °C, n = 5) and heat stress (4 °C for 120 min, H120; n = 5) groups, resulting in the identification of 636 differentially expressed genes. Identification analysis of the alternative splicing events revealed that heat stress-induced alternative splicing events increased by 20.18%. Compared with other types of alternative splicing events, the alternative start increased the most (43.40%) after heat stress. Twenty-eight genes were differentially alternatively spliced (DAS) between the control and H120 groups, among which Acly, Hnrnpd and mir3064 were also differentially expressed. For DAS genes, Srebf1, Shc1, Srsf5 and Ensa were associated with insulin, while Cast, Srebf1, Tmem33, Tor1aip2, Slc39a7 and Sqstm1 were enriched in the composition of the endoplasmic reticulum. In summary, our study conducts a comprehensive profile of alternative splicing in heat-stressed rats, indicating that alternative splicing is one of the molecular mechanisms of heat stress response in mammals and providing reference data for research on heat tolerance in mammalian livestock.
