Inclusion Impact of Jack Mackerel Meal in the Red Sea Bream () Feeds Replacing Various Animal Protein Sources for Fish Meal.

This study aims to elucidate manipulation impacts of jack mackerel meal (JMM) in the red sea bream () feeds replacing various animal protein sources for different levels of fish meal (FM) on growth and feed availability. Two-way ANOVA experimental design was applied with three substitution sources: animal protein sources (tuna byproduct meal (TBM), chicken byproduct meal (CBM), and meat meal (MM)) and two FM substitution levels (25% and 50%). The control (Con) diet contained 60% FM.

Effects of Dietary Inclusion of a Crude Protein Source Exhibiting the Strongest Attractiveness to Red Sea Bream () on Growth, Feed Availability, and Economic Efficiency.

Dietary incorporation of an attractive feed protein source is a practical method of enhancing feed intake and consequently improving the growth of fish. The attractiveness of 18 crude protein sources to juvenile red sea bream () and the effects of the dietary inclusion of the crude protein source that exhibited the strongest attractiveness on growth, feed availability, and economic efficiency were determined. Jack mackerel meal (JMM) showed the strongest attractiveness to red sea bream among 18 crude protein ingredients.

Dietary Replacement Effect of Fish Meal by Tuna By-Product Meal on Growth and Feed Availability of Red Sea Bream ().

The effect of substituting fish meal (FM) by tuna by-product meal (TBM) on growth and feed availability of red sea bream () was investigated. Six experimental diets were crested to be isonitrogenous (51.5%) and isolipidic (14.
