Going futher, i am runing a nutrition experiment using black soldier fly meal (BSFM) and polychaete meal (PM) as a replacement for fishmeal targeting maturation in Litopenaeus vannamei. This is the focus of my studies. As part of my PhD research objectives I want to assess the immune competency in the shrimp after feeding this diets for 90 days in feeding trial.
My question now is am I using hemolymph or any other organ like Hepatopancreas to determine this immune competency?
