Special Issue Information

Dear Colleagues,

With the continuous development and innovation of modern genetics and biotechnology, important progress has been made in basic research on fish genomes and molecular mechanism analysis of important economic traits. More importantly, a series of breeding techniques, including selective breeding, hybrid breeding, sex-controlled breeding, polyp breeding, germ cell transplantation, whole genome selection breeding, molecular modular design breeding, genetic modification and gene editing, etc., have been established and applied to the breeding practices of fish genetics.

This Special Issue is focused on using breeding biotechnology based on the basic research of cytogenetics, molecular genetics, and genomics to explore the genes and genetic marker resources that control the economic traits of fish. It aims to establish a basic framework for fish molecular breeding and lay a theoretical and technical foundation for the cultivation of new species of fish. We also hope to analyze the polymorphism and genetic structure of fish populations in different habitats and study and evaluate the genetic resources of freshwater fish germplasm, so as to provide basic data and research platforms for the sustainable development of fisheries.

This study evaluated a diverse range of markers of feeding stress to obtain a more precise assessment of the welfare of rainbow trout in relation to inadequate husbandry conditions. A feeding stress model based on dietary soybean meal was employed to identify suitable minimally invasive “classical” stress markers, together with molecular signatures. In a 56-day feeding experiment, rainbow trout were fed diets containing different levels of soybean meal. The impact of these different soybean meal diets on rainbow trout was assessed by water quality analyses, clinical health observations, classic growth and performance parameters, gut histopathology, blood-parameter measurements and multigene-expression profiling in RNA from whole blood. Soybean meal-induced enteritis was manifested phenotypically by an inflammatory reaction in the posterior section of the intestine and by diarrhoea in some trout. These inflammatory changes were associated with decreased supranuclear vacuolation. The haematocrit values and the levels of plasma cortisol and circulating lymphocytes in the blood were increased in trout that had consumed high amounts of SBM. Notably, the increased haematocrit depended significantly on the bodyweight of the individual trout. The transcript levels of certain genes (e.g., MAP3K1, LYG, NOD1, STAT1 and HSP90AB) emerged as potentially useful indicators in the blood of rainbow trout providing valuable information about inadequate nutrition. The expression-profiling findings provide a basis for improved, minimally invasive monitoring of feeding regimens in trout farming and may stimulate the development of practical detection devices for innovative aquaculture operations.
