Growth and histomorphological responses of Chindongo socolofi to the long‐term replacement of fish meal with defatted Tenebrio molitor meal

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The long‐term suitability of defatted Tenebrio molitor larvae meal (TM) as a substitute for fish meal (FM) protein was evaluated in Chindongo socolofi over a 170‐day feeding period. Six isonitrogenous (38% crude protein) and isoenergetic (4396 kcal kg−1) diets were formulated, in which TM protein replaced FM protein at 0% (control), 20%, 40 ...
