Growth Performance, Growth-Related Genes, Digestibility, Digestive Enzyme Activity, Immune and Stress Responses of <i>de novo</i> Camelina Meal in Diets of Red Seabream (<i>Pagrus major</i>)
A 60-day experiment was designed to assess the effect of different ratios of fish meal (FM): camelina meal plant protein (CM) on growth response and relative gene expression of growth-promoting factors, feed utilization potency, digestive enzymes activities, apparent digestibility (ADC), stress resp...

The lowest growth, feed utilization, enzyme activity, and digestibility were recorded in fish fed CM33.
